INSTALLATION PROCEDURES
IMPORTANT
- READ THESE INSTRUCTIONS CAREFULLY These instructions provide specific information for this product that
must be followed for correct installation and calibration. Incorrect
installation will reduce performance, damage the console, or
damage other equipment in the studio. Arrakis Systems does not
take warranty responsibility for equipment that is not installed per
this manual.

INSTALLATION PROCEDURES
3-1) UNPACKING & PHYSICAL INSTALLATION
3-1a) UNPACKING
The 1200 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 receipt. 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 1200 Series console, if tabletop mounted, does not require a hole for the console itself. However, holes must be provided for cable
routing. See Section 3-1g for locations and dimensions of cutouts.
There must be sufficient clearance above the console (>13") to accomodate the upward and forward hinging top panel. Refer to
the diagram on the next page for console dimensions and clearances.
In general, the console should be installed in a tabletop 24"-36" deep with at least 3" to 4" of clearance on either side, 13" clearance above
and 6" clearance in front.
The console can be screwed down to the tabletop if deemed necessary. Holes are provided through the bottom of the console
behind the motherboards.
3-1c) THRU-TABLE INSTALLATION
While the 1200 console does not require a through the table mounting system, it may be mounted through the table for a more trim
line look. To do this, a hole is cut through the table surface to the dimensions described in Section 3-1h such that the console drops
down to the edge of the wood side and front trim. Over hangs on all four sides of the console make a through the table mount an
easy and attractive option for the console.
3-1d) POWER SUPPLY INSTALLATION
The console‘s power supply (Arrakis model number TPS2) is cabinet mount (not rack mount). Be certain to provide enough
ventilation to insure adequate power supply cooling.

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 NEVER be defeated the third prong of
the AC power plug (AC System Ground). This should 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 connected to Electronic Ground. It is not connected to AC Ground or RF ground. There is no AC in the console
itself. For RF protection, the chassis should be grounded to main station ground. To connect the console chassis to ground, a 1/4" holes
are provided for a grounding stud. The holes are located on the bottom rear of the chassis, to either side. 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. Be sure to a studded
lock washer that will penetrate the paint surface and securely connect to the aluminum of the chassis itself.

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 !!

NOTE: A ground loop is created when chassis and electronic ground are connected in both pieces of equipment. This is generally
accomplished through the AC ground on the third prong of the AC power cord or by connecting the audio cable shield at both ends.

Unbalanced source ground loop
Electronic
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 theground 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.

3-3f) UNBALANCED SOURCE OUTPUT THROUGH AN ISOLATION TRANSFORMER TO BALANCED

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 600 ohm audio transformer is used whose inputs and outputs want to see a fixed impedance of 600 ohm 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 600 ohm for a 600 ohm
transformer. Different transformers and resistors may have to be used for proper impedance matching.

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 253 ohm

3-4e) CONSOLE OUTPUTS TO TELEPHONE LINES
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 (preferably) 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 (>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 TOOLS & CRIMPS 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 intermitant 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.
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 free joint. Too much solder will inhibit pin insertion.
7) INSTALL the pin into the housing (after all crimps on the cable end are completed).
NOTES
1) The connector and pins are made by AMP. CONNECTOR HOUSING = AMP P/N 350720-1
.086" FEMALE CRIMP PIN = AMP P/N 350689-1
2) A PIN EXTRACTION TOOL is available to remove pins from housings. AMP P/N 305183
3) If the wire is too large to effectively crimp, try just soldering the pin on without crimping.

3-8) SUSTAINED LOGIC
For situations such as an external channel 'ON' tally lamp, the 1200 Series Console provides a transistor driven logic output for four of the five input
channels on each input board. The circuit activates when the channel is turned ‘ON’.
This transistor output driver should be used to drive an external relay for interface to other equipment, although it may drive a LED directly through
a 1k ohm resistor.
WARNING - Maximum current allowed is 50mA.
Improper use will destroy the channel‘s drive transistor.

CUE SYSTEM, TALKBACK SYSTEM, ON-AIR RELAY
3-11) CUE SYSTEM
The 1200 handles CUE two ways:
1) AUTOCUE feeds cue audio into the right side of the monitor system while ducking the program audio.
2) &/or connect the mono CUE Output to an external cue amp.
a) Mono Cue Output - the Cue output on PIN 7 of connector CN-5 is a mono mix of a stereo cue feed. Output level is about +4dBu and low impedance
to drive
. speaker. This output will mute when the console muting bus is activated by an open MIC (the MIC channel‘s MUTE JUMPER
an external power amp and
must be in place)
b) How to disable AUTOCUE - Cutting a wire jumper (shown below) will defeat AUTOCUE’S DIM feature. Cutting the two resistors indicated defeats the
audio feed into the monitor/earphones.

TALKBACK AUDIO & MONITOR DIM INPUTS
3-12) TALKBACK SYSTEM
The 1200 features a talkback input to the monitor-cue system. Audio (typically
from another studio) fed to the talkback input appear on the right earphone and
will monitor speakers, as well as the CUE output. The DIM LOGIC feature
allows you to duck the monitor program audio‘s level so that the talkback
rides over the program audio.
a) TB AUDIO IN
An unbalanced talkback audio input is on Pin 9 of CN-5. The input gain stage
has a gain of 10 for low level signals. Add an external series resistor of
value 10k ohm - 100k ohm to reduce the level to match your talkback
audio feed.
b) TALKBACK SWITCH & LAMP
may be wired for any purpose.
c) DIM LOGIC IN

3-15) MIX MINUS CHANNEL ASSIGNMENT
The 1200 Series Console features a Mix Minus system which may be used for telephone or remote feed applications. Audio is sent to this
‘MIX (-)’ bus from all assigned channels in the console. A jumper is used to assign a channel. If the jumper is in place, a mono mix of the channel‘s
signal is placed on the MIX (-) bus when the AUDITION bus assign switch is pressed (except on 5 channel consoles, where there is no a
udition switch) and when the channel is turned ON.
For TELCO applications, all console channels EXCEPT for the phone channel should be jumpered for MIX (-). The console‘s MIX (-)
output (on the Output Board, see Section 3-10) is fed to the telephone hybrid for audio return to the caller. The hybrid receives all console audio
except for the caller‘s audio so that there will not be feedback in the system.
MIX (-) is assigned for each channel at the factory. To unassign a channel for TELCO use, simply remove the black two pin jumper on that
channel.

3-16) CALIBRATION
3-16a) GENERAL CALIBRATION
- The console has gain adjustment trim pots on each input channel, and the output amps.
- Line level input channels 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 - 10dBV (consumer) to +8dBu (professional).*
- MIC level input channels have approximately 30dB of trim and can accomodate MIC level signals from - 65dBu to -35dBu.
- The output amp 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 Cue and Monitor Outputs have fixed gain, although the External Monitor Inputs are adjustable.
3-16b) FACTORY PRESET LEVELS
The console is factory pre-calibrated for +4dBu IN = +4dBu OUT = 0VU. Therefore, when a +4dBu balanced 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 signal. MIC inputs are calibrated for -55dBu IN = +4dBu OUT = 0VU.
3-16c) 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 THE VU METER DRIVER TRIMPOTS NEED
BE ADJUSTED. See the following pages for VU meter trim pot locations.
CAUTION - Trim pots are very easily bumped out of calibration so take care to not touch the wrong ones.
VU METER RECALIBRATION PROCEDURE
a) Generate a test tone and feed this tone BALANCED into an input channel. 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 channel, and hook the GROUND from the signal
generator to the (-) input on the channel. This is effectively a balanced connection.
b) calibrate the output of the tone generator to your chosen station operating level using a voltmeter.*
d) set the channel fader at the thick black line. Turn on the channel & assign to PGM.
e) select PGM on the Monitor Select Switch
c) adjust the VU METER DRIVER trim pots such that the meters read 0VU.
The outputs of the console will now be at your station operating level when the VU meters read “0VU” and the console‘s internal gain structure
has preserved. 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 - 0dBu = 0.775 VRMS with no load. dBu is compatible with all active-balanced equipment (low Zout, high Zin). If 600 ohm transformer
balanced equipment is used, these calibration levels may change.
-10dBu = 0.245VRMS
0dBu = 0.775VRMS
+4dBu = 1.225VRMS
+8dBu = 1.945VRMS
IMPORTANT - Some voltmeters are optimized for 60 cycles and will not be accurate at midband audio frequencies (1kHz).

INSTALLATION PROCEDURES
3-16) CALIBRATION (continued)
3-16d) OVERALL RECALIBRATION PROCEDURE
IMPORTANT - Overall recalibration is only necessary under unusual circumstances. Recalibrate if all trimpots are moved drastically away
from factory settings or when left and right trims are in substantially different positions. This procedure takes some time and concentration.
INTERNAL BUS LEVEL - The key to calibration of the 1200 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 levels can be calibrated then the input levels.
To recalibrate the entire console, follow this procedure:
STEP 1 - RECALIBRATE 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 600½ load on theoutput 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 beaccomplished 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
Output Board. See following pages for trimpot locations.
e) Repeat steps b), c) and d) for the PGM R meter
f) After confirming that the MONITOR SELECT switch is selected to PGM, repeat steps b), c) and d) for AUX L and AUX R VU meters.
STEP 2 - SET INTERNAL BUS LEVEL
The Internal Bus Level is identical to the levels found at the input channel‘s IC4 OP AMP. The optimum bus level is -2dBu.
a) Connect your voltmeter, dB meter or scope between an input channel‘s IC4 PIN 1 and AUDIO GROUND. This is an GROUND. This is an
unbalanced measurement of the LEFT bus level.
b) Adjust the input channel‘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 input channel‘s IC4 PIN 7. Adjust the RIGHT input trim pot until the signal 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 Board calibration.

3-16) CALIBRATION (continued)
3-16d) OVERALL RECALIBRATION PROCEDURE (continued)
STEP 3 - RECALIBRATE OUTPUT BOARD
With the bus levels held at -2dBu, the Output Board can be calibrated. Only the OUTPUT LEVEL trim pots need adjustment. The VU METER
DRIVER trim pots have already been done!
a) Select AUD on the Monitor Select Switch
b) Adjust the PGM trim pots until the PGM VU meters read “0VU”.
DO NOT TOUCH THE VU METER DRIVER TRIM POTS!! ONLY THE OUTPUT LEVEL TRIM POTS.
c) Adjust the AUD trim pots until the AUX VU meters read “0VU”.
STEP 4 - RE 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.
d) Set the module‘s fader at the thick black line Turn on the channel & assign to PGM.
c) Adjust the input‘s trim pots such that the meters read 0VU.
d) Go on to the next input
e) 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 1200 Series console to consumer level (-10dB) equipment, simply increase the gain on that particular
input module until the console‘sVU meters read “0VU”.
Recalibration is now complete!
NOTE: Problems with calibration can add hum, noise, pops & clicks, distortion etc. Call the Arrakis Analog Customer Service Dept. at the factory if you have these
symptoms or trouble with calibration.
3-16e) EXTERNAL MONITOR INPUT CALIBRATION
The External Monitor Inputs have trim pots which allow roughly 10dB of adjustment. To calibrate:
a) Feed a balanced signal into an External Monitor Input at your station operating level (typically +4dBu)
b) Press the Monitor Select switch for the input you are feeding (EXT 1 or EXT 2)
c) Adjust the right and left trimpots such that the AUX VU meters read 0VU
d) Repeat for other input

TRIMPOT PLACEMENT AND USE
a) Audio Output Trimpots - The Pgm & Aud output trimpots will adjust gain by roughly 10dB . The trim level is factory set for +4dBm
as 0VU on the meters.
b) VU Meter Trimpots - The VU meter trimpots adjust from -10dBm to +8dBm for a 0 VU display. The factory calibrates the meters
for +4dBm at 0 VU.
c) External Monitor Input Trimpots - These trimpots adjust from -10dBm to +8dBm input for trimming the level of external audio
inputs to the monitor system.

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 deadlyAC line voltage is present within the power supply cabinet.
4-1c) GROUNDING
THE POWER SUPPLY CABINET MUST BE GROUNDED AT ALL TIMES!!! ground is totally. Grounding is accomplished by
plugging the power supply into a grounded three prong AC outlet. The power supply‘s electronic 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 power supply cabinet MUST be grounded through other means. Failure to do so will result in a safety hazard.

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. Information is also provided regarding variations in test data due to differences in equipment and procedure.
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 20,000Hz. In broadcast, this test is typically performed from 50 Hzto 15,000Hz.
Generally, the frequency response specification is 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 specification varies greatly between manufacturers.
A typical 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).

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.

All Arrakis consoles feature “Active Balanced” (electronic balanced) inputs and outputs.
That is , there are no transformers or inductors in the signal path. Accordingly, there is
no midband ripple at all. The frequency response is flat across the product’s entire
bandwidth (between the upper and lower roll off frequencies). The product’s bandwidth
is strictly controlled by internal RC time constants.
5-12 SIGNAL TO NOISE RATIO
5-2a) DEFINITION
The purpose of this test is to measure the noise floor of the console and compare it to
the nominal signal level. This will tell us the console’s signal to noise ratio (SNR). The
maximum signal level can be also be measured then compared to the console’s noise
floor thereby quantifying the console’s dynamic range.
5-2b) TEST
This is extremely difficult to perform due to differences in test procedures, setup and
equipment. Many times consistent results are elusive. Careful attention to test p
arameters 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 applie to a console input, either mic or line, at a known level and
impedance. the AC millivoltmeter is connected to a console output, 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 output level is
recorded. This is the ‘signal’ part of the SNR measurement. Th input signal is them
emoved from the console and the noise level is measured using the AC millivoltmeter.
The RATIO between the SIGNAL out of the console and residual NOISE measured by
the millivoltmeter is the 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 SNR specifications between equipment manufacturers. Differences in signal levels, input and output impedences, 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. Furthermore, once the console is installed,
60 cycle hum (even if very, very low) can be the limiting noise factor in this test.
5-2c) CONSOLE PERFORMANCE
SNR TEST: MIC LEVEL INPUT - most microphones have a low-Z output. These
MICs require, for proper performance, that the input impedance of the console be
matched to the MIC’s output impedance. The input impedance of the console is very
high, therefore and impedance matching resistor must be placed across the MIC input t
erminals. 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 (+) unput 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 (+) terminal to ground in the balanced signal generator case. Use a millivoltmeter
to confirm that a -50dBm calibrated setting from the signal generator. This setting is
typically calibrated for a 600 ogm load, NOT a 150 ohm load. Set the channel fader to
normal the operating position ( the ‘thick black line’ or ‘in hand setting’). the input
module should alredy be calibrated for normal bus level (see “Calibration’ section of the
manual). Make certain that only one input channel is on. Adjust a ouput summing amp
rimpot to give a +8dBm (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 ouput is the NOISE. Compute SNR using the formula shown
on the previous page.
SCR TEXT: LINE LEVEL INPUT - Apply a +8dBu (1.95 VRMS) tone from the signal
generator to a line level input module. The connections 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 proper bus level (see ;Calibration” section of the manual). Adjust a output summing
amp trimpot to give a +8dBu (1.95 VRMS0 at one 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.

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 frequency above 45kHz. This increase in the
noise floor occures outside the audio frequency band and can (should be) ignored. A
broadband noise measurement would includes those frequencies above 45kHz hence
this type of measurement would be misleading. Therefor a 20kHz 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 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 the signal. This
would measure .1% 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.

5-4) CROSSTALK
5-4a) DEFINITION
Crosstalk is a measure of the amount of signal that bleeds from one audio chain into
another. Problems occur when producing two separate programs on a console at the
same time or when cueing during programming. If audible crosstalk occurs, then ON
AIR integrity can be compromised or a recording can be effected.
5-4b) TEST
Apply a test tone to one audio chain, such as Audition Left & Right. Measure, with a
millivoltmeter, how many dB down (from the applied signal) the signal appears in
another audio chain, such as Program Left or Right.
5-4c) CONSOLE PERFORMANCE
Crosstalk takes place in two basic ways. The first is capacitive crosstalk which
increases by 20dB 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
ordinary audio while capacitive crosstalk is predominantly high frequencies and
sounds ‘tinny.’

6-1) MAINTENANCE
The Arrakis 1200 Series consoles require no periodic maintenance with the exception of
occasional cleaning and lamp replacement.
6-1a) CLEANING
SWITCHES - Switches typically require no cleaning, just operate the switch a few dozen
times.
SLIDE FADERS - the Penny & Giles slide faders in the Arrakis 1200 Series consoles have
conductive plastic elements and can be cleaned with warm water. They do not require
disassembly. Remove the fader’s knob by pulling up on it. Remove the fader from the
console by removing the two mounting screw, clipping cable ties and 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 Clarostat MOD-POTS are sealed and cannot be disassem bled.
Front panel knobs may be removed by: 1) loosen the collet under the colored knob
cover then 2) lift the knob off the shaft. Replacement pots are available from Arrakis.
SURFACES - Use mild soap and wam water. Abrasives will scratch the polycarbonate
overlays, and solvents wil ruin these plastic surfaces. Damp dust the wood panels and
occasionally treat with a common furniture wax.
6-1b) ROUTINE PARTS REPLACEMENT
The front panel controls on a console are obviously 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 of a switch by noting it’s 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 replacement parts. For example, consider a channel
ON switch. this switch can typically be operated 4 million times before a failure can be
expected (4,000,000 operations MTBF). If this switch is operated once every 3 minutes,
24 hours a day, 7 days a week, this this switch has an expected life of almost 23 years!
MANUFACTURER SUGGESTED LIFE EXPECTANCY:
ON/OFF Switches - 4,000,000 operations
Momentary Switches (TALKBACK) - 50,000 operations
Latching Switches (PGM, AUD, MONITOR etc)
Faders - 100,000 operations (10% resistance change)
Lamps - 40,000 hours continuous operation

Arrakis Systems will replace, at no charge, parts that fail due to defects in material or
workpersonship during the warranty period of the product to the original owner only.
Arrakis Systems does not warranty equipment that has failed due to improper installation,
abuse, or acts of nature. It is solely at the discretion of Arrakis Systems as to whether a
part is defective under warranty conditions. Refer to Section 7 for details.
6-2c) WARRANTY SERVICE PROCEDURE
Arrakis Systems assumes that it’s customers have on staff (or access to) competent
technical personnel and adequate test equipment. If a product fail, we will first seek to
ascertain the problem over the phone and solve it at the ‘component level’ where we find
the specific part(s) that have failed and repair or replace them. This is the least expensive
and time consuming solution for you. Depending on the circumstances and at our discretion, Arrakis will replace the specific PC board that we suspect to be at fault. If replacing
PC boards does not solve the problem, then the console is to be returned to the factory
where it will be repaired (normally within 2 days) and returned to you. Return shipping
over and above the cost of UPS ground will be born by the customer.
Under NO circumstances will Arrakis Systems replace the defective console with a
new one. Under absolutely NO circumstances doe Arrakis take any responsibility
for non-factory technical expenses!!!!!!!!!

6-2d) SERVICE (continued)
6-2a) TECHNICAL QUESTIONS
To have a part replaced under warranty, you must:
1) Call or write the ‘Customer Service Dept: and describe what parts need
replacement and circumstances of the failure.
2) A RMA (Return Merchandise Authorization) number will be issued.
3) Return ALL defective parts to the factory (shipping Prepaid) to the
attention of the ‘Customer Service Dept’ with a letter referring to the
replacement parts and your NAME, CALL LETTERS, ADDRESS,
DATE & RMA NUMBER.
IMPORTANT - If the defective parts are not returned within 30 days, you will be invoiced
for them and it will be assumed that they do not fall under warranty. Also, wuntil it is
cleared up, further customer service may be refused.
SPARE PARTS - A spare parts kit is provided with the console. these parts are provided
to take care of emergency failure. These parts, when use to replace failures, are not
replaced under warranty.
PURCHASED PARTS - Any Arrakis customer may purchase spare or replacement parts
from the factory at reasonable prices. Arrakis does not believe in operating it’s Customer
Support Department as a profit center and therefore charges as little as possible. We
have a fixed serivce charge tocover paperwork expenses to which we add the price of the
parts and shipping expenses.
PAYMENT OPTIONS - Parts may be purchased either by:
1) C.O.D. shipping
2) Credit Card
3) Through an Arrakis authorized dealer, who may offer terms. Arrakis does
not sell items on account or payment plan, although dealers may.
IMPORTANT - Non-payment or late-payment for parts will make it necessary to
refuse further customer service support until the issue is resolved.
