A WELCOME TO THE 12,000 SERIES
The 12,000 Series consoles represent the pinnacle of over two decades of dedication to audio broadcast
console design by Arrakis Systems, inc. These consoles combine the engineering and manufacturing
excellence that has made Arrakis #1 in radio console unit sales in the United States & well respected
throughout the world!
The 12,000 console is a unique synthesis of old and new technologies. It was engineered for the specific
purpose of creating a new Arrakis console standard. The concept was to create a console for all markets.
To do this, the product had to be flexible, reliable, and easy to service. For ease of installation, service
and expansion, the console is entirely front panel modular. Breaking new ground, the console is also of a
universal bus design. This means that every audio bus, logic bus, and audio output is supported in each
module position in the mainframe, hence any module may be placed in any mainframe slot. More importantly, it removes the functional limitations imposed by fixed bus mainframe designs. With three mainframe sizes of 8, 18, & 28 input module slots , the 12,000 fits any size market or application.
To be able to function in all market sizes, the 12,000 also supports a large standard complement of modules. There are four types of input module. Each features two stereo active balance inputs and three stereo assignable bus outputs. There is a basic MIC level input module, a more advances MIC input module
(with PAN), a basic line level input module and a more advanced line level module (with INPUT MODE
select). The console supports the control room and two studios with comprehensive monitoring and
talkback/intercom systems. All three stereo buses are individually metered. Mono sum outputs are standard. Two internally assignable mix-minus buses support the telephone interface and are pre-set once by
the engineer and should be left alone. Once set up, the telephone operation is user transparent requiring
no additional action by the console operator. A ten minute up timer with panel controls and module reset
capability is standard. All input modules, of course, support advanced logic control such as remote turrets, remote start and stop of sources, ready status lights, etc. A variety of option modules are also available such as D.A. modules, remote selector (input expander) modules, turret modules and digital workstation control modules.
The input modules features VCA (voltage controlled amplifier) control of audio to eliminate noisy faders
due to time and wear. No audio passed through the fader and ON/OFF switches, just DC control voltages. Only the finest quality components are used throughout such as Penny & Giles slide faders, custom
conductive plastic rotary faders with stainless steel shaft and bushing, ITT-Cannon switches, heavy aluminum panels, and solid furniture quality oak trim. Only gold PC board connectors are use. All IC’s are
socketed. Modules are programmable via DIP switches. The TURBO series of the 12,000 console line
features an attractive and durable polycarbonate overlay on each module, improved ON/OFF switches
with refined electronics an PC boards. The TURBO series also features a more comprehensive
talkback/intercom system with station call and answer capabilities. Attention to detail makes the 12,000
perfect for the rugged professional broadcast environment.
The 12,000 is a truly remarkable console. The application of Arrakis ingenuity and creativity have made
these consoles a major market console in features and performance. The advantage of Arrakis volume
buying and manufacturing experience have brought these consoles within the budget of most small and
medium market broadcasters. Rugged, reliable and with the features and performance to match any
product on the market, the 12,000 Series Consoles is a console designed with today’s digital audio
world in mind

OPERATING INSTRUCTIONS
2-0) GENERAL OPERATING INSTRUCTIONS
2-0a) GENERAL DESCRIPTION
The 12,000 Series console is a sophisticated electronic product with many automatic features. It is highly recommended that users carefully
study the console‘s operation before going ON AIR or performing production. The console is designed to be very user friendly and therefore
relatively easy to operate. Learning to use the 12,000 can be an enjoyable and rewarding experience.
2-0b) PROPER CONSOLE OPERATION
The 12,000 is manufactured to the state-of-the-art in terms of ruggedness of design, ease of use, and surviving the often harsh broadcast
environment. Premium grade electronic and mechanical components are used throughout. The life of the console, however, can be
dramatically extended if care is taken in day to day operation. Abuse of switches and faders will reduce effective life to only a few years or less.
Painted surfaces, while they consist of the hardest epoxy paint available, will scratch and wear quickly if abused. Polycarbonate overlays are
susceptible to gouging and scratching if they are subjected to sharp instruments. All efforts have been made to make the console as “DJ
proof” as possible, however, heavy handed operation, spilled liquids, heavy smoke and ball point pens can ruin even the most durable
equipment.
With proper care and maintenance the 12,000 will function reliably and attractively for many years.

the studio who is calling. When a studio is calling the control room the appropriate TALKBACK button will
light up (CALL INDICATOR) telling the control room operator which studio is on the line (“CALL LOGIC
FROM” a studio). When a studio is calling, the normal program audio into the control room monitor and
headphones will DIM (or DUCK) allowing the TALKBACK audio to be heard. DIM level is adjustable)

3-1) UNPACKING & PHYSICAL INSTALLATION
3-1a) UNPACKING
The 12,000 Series console is shipped in a specially designed cardboard shipping container with foam fill. This box contains the console
but not the power supply or installation supplies. The power supply is shipped in a seperate cardboard carton along with the manual, spare
parts kit and installation kit. Check all cartons and equipment for shipping damage immediately upon recipt. If any damage is found
contact Arrakis Systems immediately at (970) 461-0730. Do NOT throw away any packaging material until after console installation is
complete and satisfactory.
3-1b) TABLETOP INSTALLATION
The tabletop version of the 12,000 Series console does not require a hole for console mounting, however holes must be provided for cable
routing.
There must be sufficient clearance above and behind the console to accomodate the upward hinging meter panel. Refer to the
diagram on the next page for console dimensions and clearances. In general, the console should be installed in a tabletop 36" deep with
at least 3 to 4" of clearance on either side, 10" clearance above and 6" clearance behind.
The console can be screwed down to the tabletop if deemed necessary. Holes can be drilled through the bottom of the console in
front of and behind the motherboards. The console can then be screwed down.
Arrakis Systems does not cover under warranty any damages incurred due to improper installation, therefore take care when
drilling holes in the console mainframe. Even the smallest metal filing can cause a short circuit. Take appropriate steps to see that no metal
debris gets under the motherboards or in the electronics. It is highly recommended to vacuum out any filings ordebris (as a result of drilling)
from the console mainframe before powering up the console.
3-1c) THRU-TABLE INSTALLATION
The thru-table ("Deluxe") version of the 12,000 Series console requires a mounting hole in the tabletop. See the next page for hole
dimensions.
The console can be screwed down if deemed necessary. It is suggested to screw the console down by drilling
holes up through the tabletop into the console‘s wood side panels.
3-1d) POWER SUPPLY INSTALLATION
The console's power supply mounts beneath the tabletop, up under the table. It may also be mounted in the bottom or side of a cabinet.
The power supply should be screwed down utilizing the screw holes provided for that purpose. Be sure to provide enough ventilation to

INSTALLATION PROCEDURES
3-2) GROUNDING
3-2a) GROUNDING OVERVIEW
An audio installation is only as good (or bad ) as its grounding system. Poor grounding practices are the number one cause of RF
interference, hum, crosstalk and noise.
Grounding is used for FOUR distinct and different purposes:
(1) SAFETY FROM SHOCK HAZARD
(2) SHIELDING FROM RF INTERFERENCE
(3) AC POWER DISTRIBUTION
(4) REFERENCING BETWEEN TWO OR MORE
PIECES OF ELECTRONIC EQUIPMENT
(ELECTRONIC GROUND)
These four purposes are often at odds with each other and therefore require separate grounding systems. As an example, AC
power ground carries large current and creates transients as equipment is turned on and off. It is therefore not a clean ground and
should not be used for or connected to Electronic Ground where it will induce noise. As another example, RF ground should drain
RF energy away from electronic semiconductor devices AND Electronic Ground where the RF can be reintroduced into the
equipment. A last example is Shock Hazard ground (Chassis ground) which is AC ground from the third prong of the AC power
plug. This ground is normally connected to the metal chassis of the electronic product to prevent shock hazard. If this ground is
connected to Electronic Ground and an unbalanced signal wire is used (it will have Electronic Ground also), then there are two different
ground paths and a ground loop is created with its associated 60 cycle hummmmmm. The important point in this discussion is to
remember the basic principle that Electronic Ground must remain pure and NOT connected to (1) Safety Ground (2) RF Ground
or (3) AC Power Ground. Star ground networks are effective in reducing crosstalk and hum.
IMPORTANT - SMALL STUDIOS CAN BE ASSEMBLED USING SLOPPY GROUNDING PRACTICES
AND OFTEN WORK ACCEPTABLY. HOWEVER, THAT IS SIMPLY LUCK. GOOD GROUNDING
PRACTICES SHOULD ALWAYS BE USED.

INSTALLATION PROCEDURES
3-2) GROUNDING (continued)
3-2b) CONSOLE GROUNDING
The console has two parts. One is the console itself, the second is the power supply.
POWER SUPPLY GROUND
Since the power supply contains AC, the chassis of the power supply is connected internally to the third prong of the AC power plug (AC
System Ground). This should NEVER be defeated through the use of a 3-2 prong adapter. If the chassis of the power supply is not
grounded a serious shock hazard exists. The Electronic Ground from the open-frame supplies in the cabinet are FLOATED with respect
to power supply Chassis Ground. The 3-2 prong adapter therefore will not remove a ground loop since none exists.
CONSOLE CHASSIS GROUND
The chassis of the console is ENTIRELY floating. It is not connected to Electronic Ground, AC Ground or anything else. There is AC in the
meter panel to the timer module. Therefore, the chassis of the console MUST be grounded for AC shock protection . It should be
connected to Station Ground for AC protection, to drain static shocks from the chassis and to shield against RF Interference.
To connect the console chassis to ground, a 1/4" hole is provided for a grounding stud. The hole is located on the bottom right side of the
mainframe beneath the Meter Bridge. In high RF fields, or highest quality installations, a 4 inch copper ground strap should be used to ground
the console chassis to the main Station Ground. The Meter Bridge can also be grounded for added safety. Be sure to scrape away
any paint which may compromise the ground integrity.
The 12,000 Series console features a GROUNDING STRIP which runs across the rear of the mainframe. This strip can has a series
of tapped holes (4-40) which can be used to affix ground wires to the console mainframe. It is suggested to run a ground strap from this strip
to the 1/4" grounding stud discussed above. Once again, be sure to scrape away any paint when affixing ground wires to the strip.

3-2c) GROUND LOOPS
Modern audio consoles do NOT generate 60 or 120 cycle hum. Hum is caused by 60 cycle radiation from power supply transformers
located too close physically to electronic equipment (generally 1"-6") or by GROUND LOOPS.
A ground loop is a low frequency LOOP ANTENNA which picks up 60 cycles being radiated within the building from its AC power
distribution system. The loop is created when two pieces of equipment have more than one ground path between them.
THE WAY TO REMOVE THE HUM IS TO SIMPLY TO BREAK THE LOOP !!

CHASSIS
GROUND
A typical ground loop is formed when Electronic Ground is connected within the product to Chassis Ground. Unbalanced semi-pro
equipment is often built this way. Unbalanced equipment requires that Electronic Ground be connected through the audio signal
cable between the two pieces of equipment. The third prong of the AC power plug completes the ground loop. Lifting of the third
prong or insertion of an audio isolation transformer are the only ways to break the loop.
Shield ground loop
shield
Another typical ground loop is created when audio cabling has the shield connected at both ends between two pieces of equipment.
It doesn‘t matter whether the shield is connected to Chassis or Electronic Ground, it is incorrect. Correct procedure is for the shield to be
connected at ONE end only and that end should be the SOURCE equipment chassis. Remember, the only purpose for the
shield is to drain RF interference to ground away from Electronic Ground and any electronic components. That means that
grounding of the shield is only required at one end.

In some situations an Isolation Transformer is required to solve tough RF Interference or ground loop problems where the Source
Output is unbalanced. The Isolation Transformer must be impedance matched to both the source and the console.
Typically a 600½ audio transformer is used whose inputs and outputs want to see a fixed impedance of 600½ for it to meet frequency
response and distortion specifications. The Console Input is high impedance (>10,000 ohms). To match impedances, a 600 ohm
resistor must be placed across the input of the console as shown below.
Most unbalanced sources are low impedance but not all. Check the Zout spec of the source device to insure the proper matching
resistors are placed in series with the transformer primary leads. The total resistance, Zout + Zseries, should equal 600½ for a 600½
transformer. Different transformers and resistors may have to be used for proper impedance matching.

3-4c) CONSOLE BALANCED OUTPUT TO TRANSFORMER BALANCED INPUT
The console Output is low impedance (<100 ohms) and can therefore directly drive only ONE 600½ input impedance transformer
balanced input without a distribution amplifier. The transformer needs to see a 600 ohm balanced driving impedance for
accurate frequency response and low distortion. Each console Output has a 47½ series resistance already built in. This means
that a 253½ (255½ is the closest standard value) series resistor must be added to each leg of the balanced console output as

Under NO circumstances should a console output be used to directly drive telephone lines. The console outputs WILL be destroyed
most likely by lightning. A telephone company approved coupler or (preferrably) a telephone hybrid MUST be used. Arrakis Systems
doesn‘t, under any circumstances, warranty damage due to lightning or any telephone line transients.
3-4f) MONITOR, HEADPHONE AND CUE SYSTEMS
The monitor, headphone and cue outputs are unbalanced with Zout <50½. These outputs will drive HI-Z headphones (>600 ohm)
with no difficulty. These outputs will NOT, however, drive 8½ speakers or LO-Z headphones directly. In order to interface monitor and
cue speakers to the console external power amplifiers must be used.
The monitor and cue outputs mute electronically when activated therefore do not require external muting relays.

3-4g) CONSOLE WIRING - CRIMP TOOL & CRIMP PINS
Good crimps are mandatory for reliable console operation and clean signal path. It pays to be extra careful in crimping right from the
beginning. A good crimp now may save many hours of frustration later. A good crimp will exclude air from the joint. If air gets in the crimp
joint oxidation can occur resulting in an intermittant contact. A good crimp will strain relieve the joint by grabbing the cable insulation taking
most of the strain off the wire itself.

CRIMPING INSTRUCTIONS
1) STRIP the wire‘s insulation off exposing the recommended wire length
2) TIN the exposed wire with a small amount of solder.
3) INSERT A PIN in the crimp tool such that the tool is aligned with the part of the pin which will crimp onto the tinned wire lead. Use the “B” part of the
tool for most applications. Hold the pin in place by partially squeezing the crimp tool.
4) INSERT THE WIRE into the pin to the prescribed depth then...
5) CRIMP the pin by squeezing the tool until the pin is squashed. Oversqueezing the crimp pin will cause it to easily break in half, under-squeezing
will allow the wire to slip out.
6) REINSERT the pin in the crimp tool such that the tool is aligned with the part of the pin which will crimp onto the wire insulation. free joint. Too
much solder will inhibit pin insertion.
7) SQUEEZE the crimp tool once again to crimp the insulation. This acts as a strain relief.
6) SOLDER the wire/pin joint with a SMALL amount of solder. This will insure a long lasting trouble

REMOTE START/STOP
The control logic supports remote start and remote stop of audio source devices. If a momentary
remote start closure is desired, then connect the source device‘s start lines between pins 2 and 7.
If a sustained start closure is called for, connect the source device‘s start lines between pins 2 and 5,
then flip the appropriate dipswitches to set up the module for a “SUSTAINED START” closure
(see dipswitch info). The relay will be closed as long as the module is ON. If a momentary remote
stop is desired, connect the source device‘s stop lines between pins 2 and 5. In this case no
dipswitches need to be flipped. There is no sustained remote stop closure available.

DUE TO IMPROPER CONSOLE INSTALLATION.
The remote start/stop relays are totally floating in respect to the console electronics and ground therefore they are true “DRY CONTACT”
READY STATUS
The module allows easy access to the OFF lamp for interface to a cart machine‘s “Ready Status” output. When the “OFF LAMP
(DRIVER)” and “OFF LAMP (+VDC)” dipswitches are turned off, then the module‘s OFF lamp is entirely disconnected from the
console’s electronics. The lamp will light whenever 12-14VDC (80mA) is applied between pins 1 and 4. If the “OFF LAMP (+VDC)”
dipswitch is left “ON”, then the OFF lamp will light whenever pin 4 is connected to ground (CN3-1).
CAUTION: THE “OFF LAMP (DRIVER)” DIPSWITCH MUST BE FLIPPED “OFF” BEFORE APPLYING
ANY VOLTAGES OR GROUND TO PIN 4. FAILURE TO DO SO WILL RESULT IN THE DESTRUCTION
OF THE INTERNAL OFF LAMP DRIVER!
Once again, Arrakis Systems does not cover under warranty damages resulting from improper installation. Connector CN3 handles
auxilliary audio and control logic.
PREFADER PATCH
The prefader patch allows audio processing gear to be added to the signal chain. When the
“PATCH JUMPER” (see module layout) is removed the signal chain is broken within the
module. Now the PATCH OUT and PATCH IN connections must be used to complete the
signal path. The processing gear is placed in series between the patch out and in. The levels at
the patch are around 0dBu unbalanced. With the “PATCH JUMPER” left in place the
PATCH OUTs can also be utilized as a prefader AUX send... a sort of one output DA. The
PATCH OUTs are very low impedance, <2½, therefore external resistance is suggested.
The PATCH INs have a 18k ohm input impedance.

console’s electronics. The lamp will light whenever 12-14VDC (80mA) is applied between pins 1 and 4. If the “OFF LAMP (+VDC)”
dipswitch is left “ON”, then the OFF lamp will light whenever pin 4 is connected to ground (CN3-1).
CAUTION THE “OFF LAMP (DRIVER)” DIPSWITCH MUST BE FLIPPED “OFF” BEFORE: APPLYING ANY
VOLTAGES OR GROUND TO PIN 4. FAILURE TO DO SO WILL RESULT IN THE DESTRUCTION OF THE
INTERNAL OFF LAMP DRIVER!
Once again, Arrakis Systems does not cover under warranty damages resulting from improper installation.
** Connector CN3 handles auxilliary audio and control logic. **
PREFADER PATCH
The prefader patch allows audio processing gear to be added to the signal chain. When the
“PATCH JUMPER” (see module layout) is removed the signal chain is broken within the module.
Now the PATCH OUT and PATCH IN connections must be used to complete the signal path.
The processing gear is placed in series between the patch out and in. The PATCH OUTs are
very low impedance, <2½, therefore external resistance is suggested. The PATCH INs have a
18k ohm input impedance.

DIRECT OUT
The DIRECT OUT is a postfader signal which turns on and off along with the module. It can be used as a postfader AUX send for a
variety of purposes. The level at the DIRECT OUTs are around 0dBu unbalanced. The DIRECT OUTs are also very low
impedance, <2 ohm.

STUDIO TO STUDIO INTERFACE -- MONITORING AND TALKBACK/INTERCOM
SYSTEMS
The TCRM1 CONTROL ROOM MONITOR module provides full communications facilities to accomodate the control room
and two studios. The control room, in this scenario, is equipped with a 12,000 TURBO series console. The two studios may or may
not be equipped with 12,000 TURBO series consoles. Some basic interface schemes are discussed here. There are many
variations.
I) BASIC CONTROL ROOM TO TALK BOOTH INTERFACE -- In many circumstances the 12,000 is in a control
room looking into an adjacent talk booth, news room or interview room where a few MICs are set up. There is no console in the booth.
CR MIC - Set up DIP switches for CR MUTE. This MIC is assigned to
the TALKBACK BUS via a jumper from CN3-4 to CN3-5.*
TB
HOST MIC - Set up DIP switches for ST1 MUTE. This MIC will
talk back to the control room when a ground is applied to CN1-8.
GUEST MICs - Set up DIP switches for ST1 MUTE. These
MICs will not have talkback.
HOST HEADPHONES - are connected
to the STUDIO 2 UNMUTED output (TCRM1)
GUEST HEADPHONES and STUDIO MONITOR
SPEAKERS - are connected to the STUDIO 1 UNMUTED
and MUTED outputs respectively (TCRM1).
POWER
AMP
When the console operator presses TALKBACK TO STUDIO MONITOR 1 (on the TCRM1 module) the CR MIC will be
heard through the LEFT studio monitor speaker and the LEFT guest headphones. When the console operator presses
TALKBACK TO STUDIO MONITOR 2 the CR MIC is heard through the host‘s LEFT headphone only allowing private
conversation from the control room to the host without the guests‘ listening. In both cases the RIGHT audio through the monitors and
headphones is not effected.
*This assumes the CR MIC is connected to either a TPM1-M or TPM2 MIC level input module. If the CR MIC is brought in through a line level module
(TPM1 or TPM3) then a jumper must be made from the module‘s PATCH OUT (CN3-2 or CN3-5) to the TCRM1’s TALKBACK BUS INSERT input
(CN4-5).

When the console operator in the Control Room presses TALKBACK 2 (on the TCRM1 module) the CR MIC will feed to
STUDIO 2 UNMUTED OUT LEFT. This in turn will feed the Newsroom‘s RIGHT monitor speaker and headphone by way
of the TALKBACK FROM STUDIO 1 input. The TALKBACK 1 button on the Newsroom‘s TCRM1 will also light, indicating
CALL FROM STUDIO 1 (Control Room). When the Newsroom operator presses the TALKBACK 1 button, audio from the main
Newsroom MIC will be fed, via the STUDIO 1 UNMUTED LEFT output and the TALKBACK AUDIO FROM STUDIO 2
input, to the Control Room‘s RIGHT monitor speaker and headphone. The TALKBACK 2 button on the Control Room‘s
TCRM1 will also light, indicating CALL FROM STUDIO 2 (Newsroom). If AUTOCUE has been defeated then TALKBACK
will appear on the MONO CUE OUTPUT, mixed with any CUE audio which may be present. Monitor and CUE speakers
will still mute whenever there is an open MIC.
These examples demonstrate two of the many different ways to utilize the 12,000‘s extensive remote control, monitoring, talkback and
intercom capabilities. With a bit of ingenuity, an effective system can be created for most any circumstance.
*This assumes the CR MIC is connected to either a TPM1-M or TPM2 MIC level input module. If the CR MIC is brought in through a line level module (TPM1
or TPM3) then a jumper must be made from the module‘s PATCH OUT (CN3-2 or CN3-5) to the TCRM1‘s TALKBACK BUS INSERT input (CN4-5).
NOTE Jumpers J3 and J4 must be cut on both 12,000‘s TCRM1 modules to make the intercom work properly.

3-16) MUTING SYSTEMS
3-16a) GENERAL MUTING SYSTEM DESCRIPTION
The 12,000 Series mainframe is equipped with three independant muting systems. These are: a) CR MUTE (Control Room),
b) STUDIO 1 MUTE and c) STUDIO 2 MUTE. Each input module features DIP switches that determine which muting system,
if any, is activated by that channel. The input module can be set up to mute on either the A input, the B input or both A and B. Refer to
the DIP switch setup information found on the particular module‘s Major Parts Layout page in Section 4. When the CR MUTE logic
is activated from an input module, the Control Room Monitor and Cue system outputs will mute and the CR MUTE RELAY DRIVER
output (on the TOB1 module) will activate. Likewise, STUDIO 1 MUTE logic will inturrupt the monitor module‘s STUDIO 1
MUTED outputs and activate the STUDIO 1 MUTE RELAY DRIVER. The STUDIO 2 muting system activates only the
STUDIO 2 MUTE RELAY DRIVER. There is no STUDIO 2 MUTED outputs on the TCRM1 Control Room Monitor module.
3-16b) EXTERNAL MUTE RELAY DRIVERS
The 12,000 Series console‘s three muting systems are brought out to three Open Collector EXTERNAL MUTE RELAY DRIVERS.
These outputs will drive small relays directly to activate “ON AIR” lights, logging recorders, phone ringer mute, extra muted outputs etc.
The drivers are located on the TOB1 output module (see Section 3-9).
The RELAY DRIVER OUTPUT voltages are:

3-17) MONITOR, HEADPHONE & CUE SYSTEMS
3-17a) MONITOR SYSTEM
The 12,000 Series Console features a comprehensive monitoring system which supports the Control Room and two studios.
All monitor outputs are UNBALANCED LINE LEVEL with a nominal output level (trimpot adjustable) of +4dBu. THESE
OUTPUTS WILL NOT DRIVE 8 ohm SPEAKERS DIRECTLY therefore an external power amplifier must be used.
The Studio Monitor outputs (muted and unmuted) can be utilized in a number of ways (see the TCRM1 Module Interfacing notes for
some examples). The console operator can talk back into the Studio Monitor speakers by pressing one of the TALKBACK
buttons on the TCRM1 Control Room Monitor module and speaking into the Control Room MIC (TALKBACK from Control
Room TO a studio). The talkback audio will appear on the LEFT studio monitor outputs. Note that the Control Room MIC input
module must be set up to feed the TALKBACK BUS via the module‘s TALKBACK BUS ASSIGN connector pin.
3-17b) HEADPHONE SYSTEM
The Headphone outputs are also UNBALANCED LINE LEVEL with a nominal output level (trimpot adjustable) of +4dBu. The
Headphone outputs will directly drive HI-Z (³ 50ohm) headphones but will not drive LO-Z (8ohm) headphones. Use an external
headphone amplifier to drive LO-Z headphones.
The UNMUTED Studio Monitor outputs are often wired to headphone jacks instead of monitor speakers.
3-17b) CUE/AUTOCUE SYSTEMS
The 12,000 Series Console features AUTOCUE INTO MONITOR AND HEADPHONES Whenever an
input module is placed into CUE the AUTOCUE feature is activated.
AUTOCUE will:
a) DIM the Control Room Monitor and Headphones
b) feed CUE audio into the Control Room Monitor and Headphones.
The normal program audio will DIM (or DUCK) to a preset level during CUE. This level is adjustable, via trimpots on the TCRM1 Monitor
module, for a DIM attenuation up to 20dB. DIM attenuation is factory preset to -12dB. CUE audio is automatically mixed over the DIM‘d
program audio. This is a stereo cue.
AUTOCUE is also activated during TALKBACK from a studio TO the Control Room. When the CUE/TALKBACK logic pin on
a TPM1-M or TPM2 MIC module is activated then the Control Room Monitor and Headphones will DIM and the TALKBACK
voice audio will automatically be mixed in.
The MONO CUE OUTPUT is a MONO UNBALANCED LINE LEVEL signal with a NON-ADJUSTABLE nominal
output level of 0dBu. MONO CUE volume adjust must be done external to the console. This output will not drive an 8½ speaker
directly. Use a power amplifier. This output can be used if the AUTOCUE feature is defeated.
3-17b) AUTOCUE DEFEAT
The AUTOCUE feature can be defeated. See AUTOCUE DEFEAT PROCEDURE on the TCRM1 Monitor
module Major Parts Layout (section 4-8b).

-- The console has gain adjustment trim pots on each Input module, the Output module and the module.
-- Line level input modules have trim pots which independently adjust left and right channels. There is approximately 20dB of trim
available allowing the module to accomodate input signal levels ranging from - 10dBu (consumer) to +8dBu (professional).*
-- MIC level input modules have approximately 40dB of trim and can accomodate MIC level signals from - 70dBu to -30dBu.
-- The output module has a trim gain adjust of roughly 10dB. The console can be set up to operate at nominal station operating levels
ranging from 0dBu to +8dBu.
-- The Monitor module has six trim pots which set the Control Room Monitor, Headphone and DIM levels.

The console is factory pre-calibrated for +4dBu IN = +4dBu OUT = 0VU. Therefore, when a +4dBubalanced signal is applied to a line
input module and the fader is set at the thick black line, then the VU meters will read 0VU and the console will be sending out a +4dBu
balanced output. MIC inputs are factory calibrated for -55dBu IN = +4dBu OUT = 0VU.
3-18c) ADJUST FOR YOUR STATION LEVEL
If your station operating level is somthing other than +4, then the console will need to be adjusted. Simply recalibrate the VU meters to
reflect your nominal station level (“0VU”).
DO NOT TOUCH THE OUTPUT LEVEL TRIMPOTS!!! ONLY THEVU METER DRIVER TRIMPOTS
NEED BE ADJUSTED. See TOB1 Output module Major Parts Layout (section 4-8b) for trim pot locations. The trim pots are
very easily bumped out of calibration so take care to not touch the wrong ones.
ADJUST FOR YOUR STATION LEVEL: RECALIBRATION PROCEDURE
a) Generate a test tone and feed this tone BALANCED into an input module. This should be no problem if you have a balanced test tone.
If your tone generator has unbalanced outputs hook the SIGNAL lead from the tone generator to the (+) input on the module, and hook
the GROUND from the signal generator to the (-) input on the module. This is effectively a balanced connection.
b) calibrate the output of the tone generator to your chosen station operating level.
c) adjust the fader at the thick black line
d) set the module‘s VU METER DRIVER trim pots such that the meters read 0VU. The VU METER SELECT SWITCH (located
on the left side of the VU meter bridge) should be in the top position.
The outputs of the console will now be at your station operating level when the VU meters read “0VU”. Note that the input module did not
require adjustment nor did the console output trimmers! Only the VU METER DRIVER trim pots were adjusted.
NOTE TO TMF-8 USERS: Even though the TMF-8 does not have AUD and UTL meters, those drivers must still be calibrated.
The VU meter drivers also feed the monitor, so if the AUD and UTL VU meter drivers are turned down, the monitor system will not function
properly.
VU METER RECALIBRATION PROCEDURE (continued, for TMF-8 consoles)
e) after setting the PGM VU meters to “0VU”, press the bottom position on the VU SELECT SWITCH.
f) select PGM on the MONITOR SELECT switch (TCRM1 Monitor module). The meters will now read a little low. Compensate by
moving the input module fader up until the meters again read “0VU”.
:
g) select AUD on the MONITOR SELECT switch. Adjust the AUD VU METER trim pots for “0VU”.
h) select UTL on the MONITOR SELECT switch. Adjust the UTL VU METER trim pots for “0VU”.
NOTE: 0dBu = 0.775 VRMS with no load. dBu is compatible with all active-balanced equipment (low Zout, high Zin). If 600½ transformer balanced
equipment is used, these calibration levels may change.
WARNING: Some voltmeters are optimized for 60 cycles and will not be accurate at midband audio
frequencies (1kHz).

INSTALLATION PROCEDURES
3-18) CALIBRATION (continued)
3-18d) OVERALL RECALIBRATION PROCEDURE
INTERNAL BUS LEVEL -- The key to calibration of the 12,000 Series console is to set the internal summing bus audio level
to -2dBu (.615 VRMS, 1.7V peak to peak). This maximizes headroom and signal to noise ratio (SNR) while it minimizes distortion
(THD). After the bus levels are correctly set the Output module (TOB1) can be calibrated then the input modules.
TO RECALIBRATE THE ENTIRE CONSOLE, FOLLOW THIS PROCEDURE:
STEP 1 -- CALIBRATE VU METERS
To set the console‘s VU meters you must choose a nominal audio operating level for all the equipment in your facility. This “0VU”
reference audio level is often “+4". Other common station levels are “0" or “+8". +4dBu nominal station operating level (+4dBu = 0VU)
is assumed for this discussion.
0dBu = .775VRMS = 2.2V peak to peak
+4dBu = 1.23VRMS = 3.5Vpp
+8dBu = 1.95VRMS = 5.5Vpp
a) With an audio frequency tone generator, feed a midband (~1kHz) tone into any line level input module. The level of this tone is not
important “at this time, nor is the fader setting on the particular input module, however the tone should be around +4. Feed the signal
into both left and right inputs.
b) Connect a voltmeter, dB meter or oscilloscope to the PROGRAM LEFT output of the console. Measure between
PROGRAM OUT LEFT (+) And PROGRAM OUT LEFT (-). This is a BALANCED measurement (do NOT measure
between PGM L and GROUND. That would be an unbalanced measurement). There should be no other load on the output.
Do not put a 600ohm load on the output unless the output of the console is to be wired to a 600½ transformer balanced device. Be
aware that some voltmeters are not accurate at midband audio frequencies since they may be optimized for 60 cycles.
c) Adjust the level of the tone until the voltmeter, dB meter or scope indicates +4dB. This can be accomplished by either adjusting the input
module‘s slide fader or by adjusting the tone generator’s output. Do not be concerned with the console‘s fader and trim pot setting at this
time as we are now only setting the VU meters.
d) Adjust the PGM L VU METER DRIVER trim pot until the PGM L meter reads “0VU”. The VU METER DRIVER trim pots are
located on the TOB1 Output module. See TOB1 Major Parts Layout (section 4-8b) for trim pot locations.
e) Repeat steps b) and c) for PGM R, PGM MONO (SYSTEM 18 ONLY), AUD L and AUD R
f) After confirming that the VU METER SELECT switch on the meter bridge is in the TOP position, repeat steps b) and c) for UTL L and
UTL R.
NOTE TO TMF-8 USERS: Refer to “ NOTE TO TMF-8 USERS” on the previous page. follow those steps d) - g) to finish
VU meter calibration.
STEP 2 -- SET INTERNAL BUS LEVEL
The Internal Bus Level is identical to the levels found at the input module‘s DIRECT OUT outputs. The optimum bus level is -2dBu.
a) Connect your voltmeter, dB meter or scope between the input module‘s LEFT DIRECT OUT and AUDIO GROUND. This is an
unbalanced measurement. There should be no additional load on this output.
b) Adjust the input module‘s slide fader until the voltmeter, dB meter or scope indicates -2dBu (-2dBu = .615VRMS = 1.7Vpp). It is
recommended to tape the slide fader in place to retain its setting.
c) Move the voltmeter, dB meter or scope to the RIGHT DIRECT OUT output. Adjust the RIGHT input module trim pot until RIGHT
DIRECT OUT reads -2dBu. Now both left and right audio buses are set for -2.
d) DO NOT MOVE THE SLIDE FADER OR TRIM POTS on the input module. Both left and right bus levels must be held at
-2dBu throughout the next step, Output module calibration.

3-18) CALIBRATION (continued)
3-18d) OVERALL RECALIBRATION PROCEDURE (continued)
STEP 3 -- CALIBRATE OUTPUT MODULE
With the bus levels held at -2dBu, the TOB1 Output module can be calibrated. Only the CONSOLE OUTPUT trim pots need
adjustment. The VU METER DRIVER trim pots have already been done.
a) Adjust the CONSOLE OUTPUT trim pots (see section 4-7b, TOB1 Major Parts Layout for trim pot locations) until all VU meters
read “0VU”. DO NOT TOUCH THE VU METER DRIVER TRIM POTS!! ONLY THE CONSOLE
OUTPUT TRIM POTS.
b) Carefully replace the TOB1 faceplate to protect the trim pots from unintentional changes. TMF-8 CONSOLES: Use the Meter
Bridge‘s VU METER SELECT SWITCH and the TCRM1’s Input Select switch to complete calibration as previously
described in VU Meter calibration section.
STEP 4 -- CALIBRATE INPUT MODULES
Each input module can now be calibrated to the station operating level you have chosen...“+4" in this case for line level and -55dBu
for MIC inputs.
a) Connect the test tone to the first line level input module to be calibrated. The connection should be BALANCED. This should pose
no problem if you have a balanced test tone. If your tone generator has unbalanced outputs hook the SIGNAL lead from
the tone generator to the (+) input on the module, and hook the GROUND from the signal generator to the (-) input on the
module. This is effectively a balanced connection.
b) Calibrate the output of the tone generator to +4dBu = 1.23VRMS = 3.5Vpp.
c) Set the module‘s fader at the thick black line
d) Adjust the input module trim pots such that the meters read 0VU. This can usually be done by removing the module to the right
of the module to be calibrated leaving a space to access the trim pots. The module can also be placed on the extender cables
supplied with the console to provide access to the trim pots.
e) Go on to the next input module.
f) Calibrate the MIC input modules with a small bladed screwdriver.
If all your audio source devices (cart machines, CD players etc.) are properly calibrated to your station operating level, all inputs
will be correct. Confirm calibration of the audio source devices. If there is a calibration mismatch either change the source‘s output
levels or recalibrate the particular input module in question to match the source. To interface the 12,000 Series console to
consumer level (-10dB) equipment, simply increase the gain on that particular input module until the console‘sVU meters
read “0VU”.
STEP 5 -- CALIBRATE MONITOR MODULE
The TCRM1 Monitor module, in most cases, should not require recalibration. If necessary:
a) Place the TCRM1 Monitor module on extender cables (optional) or remove the module‘s faceplate.
b) Feed a test signal into the console such that the VU meters read “0VU”.
c) Turn the MONITOR and HEADPHONES volume pots up full.
d) Make sure that no modules are in CUE. Any module in CUE will activate the DIM feature resulting in an inaccurate calibration.
e) Adjust the MONITOR and HEADPHONE TRIM pots until all the outputs read the same. The actual level is not as
important as the balance between left and right signals. See the TCRM1 Major Parts Layout page (section 4-8b) for the location
of the trim pots. The pots can be accessed by reaching behind the cabling with a small screwdriver. As previously mentioned, the
module‘s faceplate may be removed to ease trimpot access. Skip steps f) and g) if the AUTOCUE feature on the TCRM1
module has been defeated.
f) Place an unused input module into CUE. This module should NOT have any signal fed to it. The monitor and headphone
outputs should DIM.
g) Adjust the right and left DIM levels by turning the DIM trim pots.
Calibration is now complete!
NOTE- problems with calibration can add hum, noise, pops & clicks, distortion etc. Call the
Arrakis Customer Service Dept. at the factory if you have These symptoms or trouble with calibration.

3-1) CALIBRATION (continued)
3-18e) TDA1 DISTRIBUTION AMPLIFIER MODULE CALIBRATION
The TDA1 Distribution Amplifier module is normally calibrated for UNITY GAIN. That is, the level of the signal coming out is the same as
the level of the signal going in.
CALIBRATION PROCEDURE
1) Feed a signal BALANCED into the LEFT DA input
2) Measure the BALANCED output level from CH 1 LEFT.
3) Adjust the appropriate trim pot (see TDA1 Major Parts Layout, section 4) until the level OUT is the same as the level IN.
4) Repeat for channels 2, 3 and 4.
5) Repeat for RIGHT input.
6) Immediately replace the blank cover panel to protect the trim pots from being bumped. It is very easy to throw the module
out of calibration by inadvertently bumping a trim pot.
3-18f) TPH1 -- PHONE SYSTEM MODULE CALIBRATION
A trimpot on the module allows adjustment of the level of the phone hybrid in the console’s CUE system.

4-1b) FUSES
The power supply cabinet is equipped with an INTERNALAC fuse. If the fuse blows, then replace it with a 2 AMP SLO-BLO FUSE.
Use no substitutions!
NOTE: WARNING!!! ALWAYS unplug the power supply before opening the chassis. Potentially deadly AC line voltage
is present within the power supply cabinet.
4-1c) GROUNDING
THE POWER SUPPLY CABINET MUST BE GROUNDED AT ALL TIMES!!!
Grounding is accomplished by plugging the power supply into a grounded three prong AC outlet. The power supply‘s electronic ground
is totally floating in respect to the cabinet’s chassis ground (AC ground), therefore there is no advantage to removing the third prong on the
AC power cord to try to alleviate a ground loop. If the AC ground is defeated on the power cord or AC outlet then the the power supply
cabinet MUST be grounded through other means. Failure to do so will result in a serious safety hazard.

STEP 1 :
CUT JUMPER J5 TO DEFEAT
AUTOCUE LOGIC CONTROL
SIGNAL. THE MONITOR AND
HEADPHONE OUTPUTS WILL
NOT DIM DURING CUE WHEN
THIS JUMPER IS CUT.
CUT JUMPERS J1 AND J2 TO
INTURRUPT THE STEREO CUE
AUDIO FEED TO THE MONITOR
AND HEADPHONE OUTPUTS. CUE
WILL ONLY APPEAR ON THE
"MONO CUE" OUTPUT WHEN
THESE JUMPERS ARE CUT.
STEP 2 :
PERFORM THESE TWO STEPS IF AUTOCUE INTO THE MONITOR AND
HEADPHONE SYSTEMS IS NOT DESIRED. WIRE THE CUE SPEAKER
AMPLIFIER TO "MONO CUE OUTPUT".

SPECIFICATIONS & TESTING
5-0) INTRODUCTION
The performance test listed this section are:
1) Frequency Response
2) Signal to Noise Ratio
3) Total Harmonic Distortion
4) Crosstalk
The purpose of this section of the manual is to provide a general description of the measurement techniques used by Arrakis Systems.
IMPORTANT - many types of test equipment, test setups, test conditions and test methods
are used in our industry. It is impossible to provide information for all the various combinations used in the real world. For this reason all specifications listed in this manual, or in
any other published literature on these products, are general. Specifications amy change
without notice and may differ between the manual and other literature.
5-1) FREQUENCY RESPONSE
5-1a) DEFINITION
This test defines the product’s bandwidth and measures any variations in the product’s
output level as a function of frequency. In consumer audio the test is performed from 20Hz
to 20,000 Hz. In broadcast, this test is typically performed from 50Hz to 15,000 Hz.
Generally, the frequency response specification if referenced to an arbitrary 0dB. Any
deviation from this 0dB reference is specified as plus and/or minus dB over the stated
bandwidth. The frequency response spec is “+.5dB 20Hz-20kHz.” It is generally accepted
that a person with good hearing can hear a level change as small as .2dB.
5-1b) TEST
The test is performed with an audio signal generator and a voltmeter* (or oscilloscope).
The signal generator is connected either balanced or unbalanced to a console input.
The voltmeter is connected either balanced or unbalanced to a console output (such
as Program Left Output). The frequency of the signal generator is varie over the audio
band of interest (20Hz-20kHz or 50Hz to 50kHz) while recording the Program output level
on the voltmeter. nay variatin in the output level is noted over the entire frequency range.
Many newer model digital voltmeters measure in absolute and relative dB which makes
the test very simple. if you do not have this type of voltmeter, then you must calculate dB
using the following formula (see next page).
*WARNING: some voltmeters are optimized for AC line measurements (50/60Hz) and are not accurate over the entire
audio frequency range (20Hz-20kHz).

SPECIFICATIONS & TESTING
5-1) FREQUENCY RESPONSE (continued)
dB = 20[log(V1/V2)]
where V2 is the reference level (some arbitrary voltage usually measured at 1kHz) and V1
is the voltage level in question.
5-1c) CONSOLE PERFORMANCE
All Arrakis consoles feature ‘Active (electronic) Balanced’ inputs and outputs. That
is,
there are no transformers or frequency response is flat across the product’s entire bandwidth (between the upper and lower rolloff frequencies). The product’s bandwidth is controlled strictly by internal RC time constants.
5-2) SIGNAL TO NOISE RATIO
5-2a) DEFINITION
All Arrakis consoles feature ‘Active (electronic) Balanced’ inputs and outputs. That is,
there are no transformers or frequency response is flat across the product’s entire
bandwidth (between the upper and lower rolloff frequencies). The product’s bandwidth
is controlled strictly by internal RC time constants.
5-2b) TEST
This test is extremely difficult to perform due to differences in test procedures, setup
and equipment. Many times consistent results are elusive. Careful attention to test
parameters is essential to obtaining meaningful results.
The equipment needed for this test is an audio frequency signal generator and an audio
millivoltmeter.
The signal is applied to a console input, either mic or line, at a known level and impedance. The AC millivoltmeter is connected to a console ouput, Program Left for example. The levels are set up such that the VU meters read “0VU” with all the slide faders
at their nominal setting (the “thick line” or “in hand setting”). the ouput level is recorded.
This is the ‘signal’ part of the SNR measurement. The input signal is then removed
from the console and noise level is measure using the AC millivoltmeter. The RATIO
between the SIGNAL out of the console and the residual NOISE measured by the
millivoltmeter SNR. The formula for the SNR is:
SNR = 20[Log(Vsignal/Vnoise)]

SPECIFICATIONS & TESTING
5-2) SIGNAL TO NOISE RATIO (continued)
The many variable factors associated with this test make it difficult to accurately compare the SNR specifications between equipment manufacturers. Differences in signal
levels, input and output impedances, band limiting filters, test setup and other factors
have substantial impact on the test results. Therefor, SNR specs obtained using different test methods cannot be accurately compared. Futhermore, once the console is
installed, 60 or 120 cycle hum (evene if very, very low) cn be the limiting noise factor in
the test
5-2c) CONSOLE PERFORMANCE
SNR TEST: MIC LEVEL INPUT
Most microphones have low-Z output. These MICs require, for proper performance,
that theinpu impedance of the console be matched to the MIC’s output impedance. The
input impedance of the console is high, therefore an impedance matching resistor must
be placed acreoss the MIC input terminals. Place a 150 ohm METAL FILM 1% reistor
across the (+) and (-) inputs of the MIC channel. If the signal generator is UN-balanced,
then connect the (+) input to ground with a wire jumper and feed audio into the (-) input.
If you have a balanced signal generator apply balanced (+) and (-) audio to the MIC
input. Do NOT connect the (+) ternimal to ground in the balanced signal generator
case. Use a millivoltmeter to confirm that a -50dBm (2.4mVRMS) tone is being applied
to the MIC input. Do NOT rely on a -50dBm calibrated setting from the signal generator.
this setting is calibrated for a 600 ohm load, NOT a 150 ohm load. Set the channel
fader to normal, the operating positin (the thick black line or ‘in hand setting’). The input
module should already be calibrated for normal bus level (see “Calibration” section of
the manual). Make certain that onoly one input channel is on. Adjust a output summing
amp trimpot to give a +8dBm (1.95 VRMS) at on of the console outputs (no load necessary on the output). Your SIGNAL is therefore +8dBu. Remove the signal generator
leads from the input connector (remove the ground from the (+) input if applicable. the
level that you now read at the output is the NOISE. Compute SNR using the formula
shown on the previous page.
SNR TEST: LIVE LEVEL INPUT
Apply a +8dBu (1.95 VRMS) tone from the signal generator to a line level input module.
the conncteions can be either balanced or unbalanced as outlined above. An input terminating resistor is not necessary. Set the channel fader to the normal operating position. The input module should be adjusted for porper bus level (see “Calivration” section of the manual). Adjust a output summing amp trimpot to give a +8dBu (1.95
VRMS) at one of the console outputs (no load is necessary on the output). Your SIGNAL is therefore +8dBu. Remove the signal generator leads from the input connector
(remove the ground from the (+) input if applicable). The level that you now read at the
output is the NOISE. Compute SNR using the formula shown on the prevoius page.

SPECIFICATIONS & TESTING
5-2) SIGNAL TO NOISE RATIO (continued)
IMPORTANT
The IC used for the VCA (SSM2018) has a noise floor that, due to slew rate optimization, increases with the frequency above 45kHz. This increase in the noise floor occurs
outside the aduio frequency band and can (should be) ignored. A broadband noise
measurement would include those frequencies above 45kHz hence this type of measurement would be misleading. Therefore, a 20kHze or 30kHz band limiting filter
MUST be used during SNR measurements to obtain accurate results!!
Additionally,
1) A peak reading meter will measure 1.1dB better than an RMS reading meter.
2) A 20kHz filter will read approximately 1.8dB better than a 30kHz filter.
3) Stray 60/120 cycle fields and RFI will effect the test.
5-3) TOTAL HARMONIC DISTORTION
5-3a) DEFINITION
This test measures the nonlinear response of the signal chain to a fixed frequency
sinusoidal tone. A tone is applied to an audio input. A measuring device at the output
cancels (nulls) the input tone then measures the total energy of the remaining harmonics (harmonics are multiples of the frequency of the applied tone) and any noise present. The ratio of the total energy of the harmonics plus noise to that of the fundamental (applied tone) X100 is the percent harmonic distortion +N. It is generally accepted
that a good ear can hear 0.1% THD.
5-3b) TEST
A low distortion audio signal generator is connected to a console input, balanced or
unbalanced as outlined above in the SNR description. A distortion analyzer is connected to a console output, balanced or unbalanced. The distortion analyzer will null out
the fundamental frequency and read distortion in percent (%) THD+N.
5-3c) CONSOLE PERFORMANCE
IMPORTANT
A distortion test is limited by the noise in the system. As an example, a 60dB S/N ratio
means that the noise is down only 1000 times from signal. This would measure .1%
THD+N even if no distortion harmonics were present at all. An 80dB SNR means a
minimum THD+N of .01%. To find true THD, where noise limits the test, a spectrum
analyzer must be used.
Once again, attention must be paid to filtering and test setup since excess noise will
result in excess THD+N.

SPECIFICATIONS & TESTING
5-4) CROSSTALK
5-1a) DEFINITION
Crosstalk is a measure of the amount fo signal that bleeds from one audio chain into
another. Problems occur when producing two seperate programs on a console at the
same timeor when cueing during programming. If audible crosstalk occurs, then ON
AIR integrity can be compromised or a recording can be effected.
5-1b) TEST
Apply a test tone to one audio chain, such as Audition Left & Right. Measure, with a
millivoltmeter, how many dB down (from applied signal) the signal appears in
another audio chain, such as Program Left or Right.
5-1c) CONSOLE PERFORMANCE
Crosstalk takes place in two basic ways. The first is capacitive crosstalk which increases
20 dB for a ten times increase in frequency. The worst case frequency for this type of
crosstalk is therefore 20kHz. The second type of crosstalk is power supply related where
ground between two circuits is modulated by heavy currents. Ground modulation
crosstalk tends to be of a low frequency nature and sounds like bandlimited audio while
capacitive crosstalk has a higher frequency spectrum.

MAINTENANCE & SERVICE
6-1) MAINTENANCE
Arrakis 12,000 Series console require no periodic maintenance with the exception of
occasional cleaning and lamp replacement.
SWITCHES
Switches typically require no cleaning, just operate the switch a few dozen times
SLIDE FADERS
The Penny & Giles slide faders in the Arrakis 12,000 Series consoles have conductive
plastic elements and can be cleaned with warm water. They do no require disassembly.
Remove the fader’s knob by pulling up on it. remove the fader from the console by
removing the two mounting screws, clipping cable ties andn carefully pulling the connector from the PC board. To clean, simply hold the fader under a stream of warm tap water
and operate back and forth 50 to 100 times. For extremely dirty faders a mild soap solution can also be used. Allow the faders to dry TOTALLY before using (this often means
they must dry overnight). A light silicone based lube can be applied SPARINGLY to the
slide fader if required: take the cover plate off the fader (two screws) and use a swab to
apply some lube to the fader’s two guide rods. IMPORTANT: Do NOT use solvents,
cleansers or sprays on the faders. The warm water with mild soap cleaning technique is
recommended by Penny & Giles.
ROTARY POTS
The rotary pots are sealed and cannot be disassembled. Front panel knobs may be
removed by:
1) loosen the collet under the collored knob cover
2) lift the knob from the shaft
Replacement pots are available from Arrakis
SURFACES
Use mild soap and warm water. Abrasives will scratch the polycarbonate overlays, and
solvents will RUIN thse plastic surfaces! Damp dust the wood panels and occasionally
treat with common furniture wax.
6-1b) ROUTINE PARTS REPLACEMENT
The front panel controls on a console are obvious subject to ordinary wear and tear. Abusive treatment of the controls will result in a substantial reduction of their life expectancy.
Be aware of the average use each control in the console is subjected to. It is possible to
predict the life expectancy a switch by noting its frequency of use and comparing that to
the switch’s life expectancy rating. Provisions can then be made to schedule maintenance and request budgeting for replacements parts. For example, consider a channel
ON switch. This switch can be operated 4 million times before a failure can be expected.
If this switch is operated once every 3 minutes, 24 hours a day, 7 days a week, then this
switch has an expected life of almost 23 years!
MANUFACTURER SUGGESTED LIFE EXPECTANCY
ON/OFF Switches - 4 million operations
Faders - 100,000 operations (10%
Momentary Switches (Talkback, Cue, etc.) - 100,000
resistance change)
