The Control Room Monitor system
The Control Room Monitor system is the main audio monitoring system for the studio. It features an input selector switch and a volume level control. The output of the monitor system is connected to an external audio power amplifier and speakers. The level control
on the external amplifier should be set for the maximum sound level desired in the studio.
MONITOR MUTING
When a control room microphone is turned on (channels 1 through 5A), the monitor system will mute (audio turned off) so that there
will not be feedback from the speakers to the microphone.
MONITOR SELECTOR SWITCH
This switch selects the audio source for the Monitor system. Push the switch down (LED will light) to select an external input to the
monitor speakers. This is usually an off-air source so that the final output of the station can be monitored. When the switch is up
(unlighted) the Program bus output of the console is being monitored.

The Headphone system
The Headphone (earphone) system in the console is provided so that audio can be listened to while the microphone is active and the
monitor speakers are muted. The Headphone system receives the same audio feed as the Monitor system but does not mute when
the microphone channel is turned on. The Headphone system has a 1/8" headphone jack on the rear of the console. The headphone
amplifier connected to the headphone jack is designed to work with high impedance (not 8 ohm) headphones.
FIXED LEVEL HEADPHONE OUTPUT
A connector with a fixed volume level headphone output is located next to the standard Headphone connector. This output is provided
to be used with an external audio amplifier to provide headphones to all five mics.
CUE
The console features Autocue. Whenever a channel is placed into cue, the Program audio in the Headphone system will dim and the
Cue audio will play over the Program signal.
MUTING
The headphone system is not muted. When the control room microphone is turned on, the Monitor system will mute (audio is turned
off) so that there will not be feedback from the speakers to the microphone. The headphone system can not have audio feedback so
muting is not required.
MONITOR SELECTOR SWITCH
This switch selects the audio source for the Monitor/Headphone system. Push the switch down (LED will light) to select an external
input to the monitor speakers and headphones. This is usually an off-air source so that the final output of the station can be monitored. When the switch is up (unlighted) the Program bus output of the console is being monitored.

The Cue system
The cue system is designed for monitoring an audio source without placing it on air. This feature is useful for listening to a network
feed before bringing it to air, listening to a CD to be certain it is the correct song, etc. The cue system features ‘Auto-cue,’ where
cue is heard in the Monitor speakers and separate Cue speakers are not required.
ACTIVATING CUE
To activate cue, click on the CUE button on an input source channel. To exit the cue mode, click on the CUE button again. The cue signal
is PRE-fader and therefore the fader level and the channel ON-OFF status has no effect on the cue signal.
CUE AUDIO
Cue audio will be heard in the Monitor speakers and the Headphones. In the Monitor and Headphone system, Autocue will dim the Program in the headphones and play the cue audio over top of program audio.

Unpacking
a) PACKING SLIPS- do you have everything?
Check the Packing Slips that come with the shipment to be
certain that all packages have been received.
b) CHECK FOR DAMAGE
Check all packages and equipment for damage IMMEDIATELY
upon receipt.
If damage is found, contact Arrakis Systems immediately to
report the damage. (refer to inside cover of this manual for
contact information)
c) CAREFULLY GO THROUGH EACH BOX
Arrakis inspects every shipment for accuracy. You will
receive all of the appropriate documentation, install kit,
spare parts kit, and equipment. Be very careful to not throw
away anything if you decide to throw out the shipping materials.
d) KEEP ALL PACKING MATERIALS
Arrakis consoles are shipped in custom shipping containers.
Keep all containers at least until the installation is complete.
This is in case some piece of equipment may need to be
returned to the factory for service.
It is a good idea to keep the shipping materials for the life of
the product. Arrakis is not responsible for shipping damage
to products not shipped to the factory in the original packing
materials.

Before you start
a) PHYSICAL SPACE
It is important to install the console with sufficient space around it to operate and service the console
easily.
b) AREA IN FRONT OF THE CONSOLE
It is normal to have 8-10" between the front of the console and the front of the table so that a piece of
paper may be laid on the table in front of the console.
c) SCRIPT OR COPY BOARD
Are you going to use a copy bridge that spans the top of the console for paper or other objects? A copy
bridge can allow the console to be placed close to the front of the table in tight rooms.
d) ADEQUATE VENTILATION
It is important to provide adequate ventilation to electronic equipment. High temperatures can reduce the
life of equipment.
e) 110V - 220VAC OPERATION
The console comes with a 110VAC-220VAC autosensing external power supply as standard equipment.
f) STATIC
Static discharge to electronic devices can cause damage, reduce performance, or cause noise in the system. Proper choice of carpet is an important consideration when building a studio.
g) THE CONSOLE POWER SUPPLY
The console is powered by an external, regulated power supply. The supply simply plugs into the back of
the console. There are no high voltages within the console

Getting started... a MUST Read !
a) CONSUMER SOURCE EQUIPMENT
The console is designed to be used with balanced professional & unbalanced consumer type audio source equipment such as CD players, MDs, DAT
machines, cassette machines, etc. Unbalanced consumer equipment is designed to perform well in compact studios where audio cables are short.
Balanced audio is required when connecting multiple studios or with long audio cable runs ( > 10 feet). When choosing consumer audio equipment,
choose equipment that has 2 prong AC power plugs (not the 3 prong plugs).
b) AC POWER CONSIDERATIONS
Plug all of the equipment in your studio into a single AC power strip!
Unbalanced consumer source equipment is not designed to reject AC power line hum. This makes it important to put ALL of the equipment
in the studio on the same branch of the AC power and preferably on a single AC power outlet. A single power outlet will have a 1500-2000 watt
capacity. That is plenty of power for most studios. Simply plug a multi-outlet AC power strip into the single wall outlet and then all of your equipment into the power strip. If possible, the power strip should be the kind that has internal surge protection.
Because many buildings have as many as 8-12 duplex wall outlets on a single 1500-2000 watt branch, you must have NO other equipment
on any of those 8-12 other outlets. Make sure the branch your outlet is on does not also power the lights or any other building equipment.
c) SOME THOUGHTS ABOUT 60 CYCLE HUM (or some ideas about what to do if you get it)
The RCA audio cables used in consumer audio equipment connect the chassis ground and signal ground of all of the equipment in the studio together through the cable shield. All shield ground connections should be as tight and low impedance as possible. Use only high quality RCA (IHF) audio
cables.
Most consumer audio equipment will have a 2 prong AC power plug. Some equipment has a 3 prong AC power plug. The third prong on a 3
prong plug is a “Safety Ground” which grounds the chassis to reduce shock hazard. The 3rd prong must never be removed even though it creates
a 2nd ground path along with the audio cable shield ground. Two ground paths creates a “Ground loop” antenna which picks up 60 cycle AC hum. If
possible, use only equipment that has 2 prong AC power plugs. With stubborn hum, replace the equipment with 3 prong AC power plugs with equipment with 2 prong AC power plugs. This is often less expensive that making a custom audio cable with audio transformer isolation.
If there is NO other ground connected to the studio, a single piece of equipment with a 3 prong AC plug does not create a ground loop.
However, if there is another ground (such as from another studio) or a 2nd piece of equipment with a 3 prong AC power plug, then a ground loop is
completed. If you can not change to two prong equipment, it may be necessary to use an audio isolation transformer on the audio cable to break
the audio ground path. Contact a technician or the factory on how to build a transformer isolated audio cable.
In some stubborn cases of hum (or RF interference), the best solution is to make the ground resistance between ALL of the equipment as
low as possible. To do this, connect all of the equipment chassis’ together with #12 stranded, insulated wire. Each piece of equipment is to have its
own wire that returns in a star configuration to a single point in the studio. That single point should return by a single ground wire back to the main
station ground. A 2"-4" copper ground strap to station ground is best.
d) CONNECTING MULTIPLE STUDIOS
When connecting multiple studios, long audio cables are sometimes necessary. These long cables can introduce AC hum into your audio. Long audio
cables should always be balanced. If it is not possible to use a balanced output from the console, it may be necessary to use distribution amplifiers
with balanced inputs and outputs (or audio isolation transformers) to break the ground path and to cancel the AC hum.
e) STEP BY STEP INSTALLATION PROCEDURE
When building a studio, it is important to be able to isolate problems that may be causing noise, hum, or
even not passing audio. To do this properly, the studio should be assembled and tested one piece of equipment at a time. Each problem is detected and eliminated as it occurs. This manual provides a basic step by
step process to assemble and test your studio.

Step by Step Instructions
IMPORTANT- Follow this STEP by STEP procedure. Each STEP has specific tests to determine if the console installation
has been performed correctly to that point.
STEP 1- POWER SUPPLY INSTALLATION
The console power supply should be plugged into a surge protected outlet. First plug the power supply into the back of the console and then plug the
power supply into the AC outlet.
TEST- The console should now be on. To test for power, simply push one of the console On/off switches to see that the Channel On LED lights.
STEP 2- CONNECT A MICROPHONE
Connect a Microphone to the Channel One Mic input XLR connector on the back of the console.
Turn the channel one Mic on by pushing the red on button (the red on LED should now be on), and bring the slide fader on that channel to the in hand setting (0).
TEST- The VU meters on the console should move as you speak into the Microphone.
STEP 3- LISTEN TO THE MIC AUDIO ON THE HEADPHONES
Plug the headphones into the headphone jack on the back right side of the console as illustrated. The console supports only high impedance (>20 ohm) headphones. On the console, the Monitor Selector switch should be off (assigned to the Program bus) and set the Headphone Volume control to 1/2. Talk into the
mic on channel one. Adjust the headphone level control on the console to a comfortable audio level.
TEST- You should hear your voice clearly. There should be no audible hum or noise. If you hear no audio or there is hum or noise, then repeat Steps 1,2,&3.

STEP 4- MONITOR SPEAKER CONNECTION
The console has a low level monitor audio output that is designed to connect to an external audio power amplifier. The console output will not directly drive
speakers.
Connect the audio amplifier input to the console Monitor Output on the back panel of the console. The monitor output of the console is unbalanced, consumer
level and will use an RCA cable (usually supplied with the amplifier). Follow the amplifier’s instructions and connect speakers to the amplifier.
Turn the console power on and the amplifier power on. On the console, the Monitor Selector switch should be off (assigned to the Program bus) and set the Monitor Volume control to 1/2. Set the audio power amplifier level and front panel switches per the amplifier instruction manual.
WARNING- do NOT have all levels controls at maximum. Too much audio level through your speakers can damage the speakers.
To hear Monitor audio you must stream audio through one of the two Bluetooth channels or the PC USB channel. The VU meters should move with the audio and
audio should be present at the headphone jack at the back of the console. Be certain that all mic channels are turned off because it will mute the audio out of the
speakers so that there is no feedback. Audio should now be audible through the monitor speakers.
TEST- The audio through the monitor speakers should be clear and without significant noise or hum.

Turn Mic channels on (the red LED should be on) and set the channel fader to the in hand position (middle). If the mic itself has an on/off switch, then turn it
on.
TEST- Speak into the microphone and the console VU meters should follow your voice. There should be no audio out of the monitor speakers (they are muted
to eliminate feedback) but there should be audio in the Headphones.
If mic level is low, use a small screwdriver to adjust the 25 turn trimpot on the back of the console located next to the mic XLR connector.

Program Output
STEP 6- CONSOLE PROGRAM OUTPUT
The console has both balanced and unbalanced Program bus outputs
UNBALANCED PROGRAM OUTPUT
The console program output (PGM) is located on the console back panel. It is an unbalanced (-10dBu) audio output on RCA connectors.
BALANCED PROGRAM OUTPUT
The console program output (PGM) is located on the console back panel. It is a balanced (+4dBu) audio output on XLR connectors.
CONNECTING THE PROGRAM OUTPUT TO THE SIGNAL CHAIN
The console Program output is both unbalanced analog (-10dBu level) and balanced (+4dBu). The equipment that the Program output drives must accept one
of these input types and levels. You must refer to the product manual for that product. In some cases, it may be useful to connect the Program output of
the console to an audio distribution amplifier which is designed to connect analog audio products that are of different types and levels.
TEST- The Program output of the console is connected to additional equipment (processor, distribution amp, etc) to form a signal chain. Check for presence and quality of audio at each point along the signal chain.

External Monitor Input
STEP 8- OFF AIR MONITORING
The Monitor Selector Switch (EXT) is usually used to monitor the actual radio station on air signal from a radio tuner.
NOTE: it is important to monitor the actual signal from the radio station and not just the output of the console. This is so as to monitor the entire radio chain from
the console to the transmitter.
INSTALLATION
Connect the output of a radio tuner or professional on air monitor to the EXT IN connector on the back of the console.
IMPORTANT: if using a consumer tuner, use a line level output and not the speaker output.
CALIBRATION
The EXTERNAL IN is calibrated to -10dBu input level.
TEST
Set up the tuner or monitor to your station’s frequency and switch the console control room monitor to the EXT position. You should hear the audio output of the
tuner. Audio quality should be high and there should be no objectionable audio hum.

Channel 5b Balanced Input
STEP 10- CONNECT A BALANCED PROFESSIONAL AUDIO SOURCE DEVICE
The console has a balanced, +4dBu audio input on channel 5B. It uses an RJ45 connector.
Factory Cables
A prebuilt cable can be purchased from the factory with an RJ45 on the console end and your choice of XLR, RCA, or TRS
phone connectors on the other end. Or, you can build a custom cable as described below.
Custom Cable
The cable used with the RJ45 connector is CAT5. This cable has 4 twisted pairs of wires. The twisted pairs are identified
by color (ie: orange, orange... green,green... etc). Arrakis ARC consoles use 2 pairs for left and right audio [the two pairs
used by ethernet as the transmit (green) and receive pairs (orange)] . Left is the orange (ethernet transmit pair). Right is
the green (ethernet receive) pair.
Arrakis supplies a CAT5 cable with RJ45 connectors on each end with the console. Cut the cable in half (or to the length
that you need). Then attach the desired connector to the unterminated end of the cable (XLR, TRS phone, RCA, etc)
The balanced inputs are >10,000 ohm input impedance and levels are set for +4dBu signals.

Basic Calibration
The console has been calibrated at the factory to normal -10dBu and +4dBu levels and should not require field calibration.
Because the console has BOTH -10dBu consumer AND +4dBu professional outputs level adjustment is usually not required.
Also, it is better to adjust the level out of the source device than to adjust the console levels. In this way, a source device
can be moved from one studio to another without requiring recalibration.
MIC GAIN ADJUSTMENT
The only user level adjustments are on the mic channels. These trim pots are set at the factory for typical microphone gain levels. These trim pots can be
adjusted if different mic gains are required. To adjust, the simplest method is to speak into the mic and adjust the trim pot with a small straight edge screwdriver until the desired level is reached.

General Repair Considerations
WARNING
The console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before
beginning any type of repair or opening the console CALL Arrakis customer support for recommendations.
DESIGNED FOR MODULAR PART REPLACEMENT
The ARC series console is designed for modular replacement rather than repair. The power supply is external and plug in. Most ICs are plug in, and a physical
board layout is provided with descriptions of the functions of each IC. ICs can be individually replaced to test for functionality. A small amount of disassembly
is required. Diagrams on the following pages explain the required disassembly.
PC BOARD COMPONENT LEVEL REPAIR
If possible, PC board component level repair requiring soldering should be performed at the factory. In particular, replacement of slide faders and switches
should be performed at the factory. If the repair must be made in the field, then extreme care must be taken to not damage the PC board or other components.
Arrakis can not warranty non-factory service.
POWER SUPPLY
The power supply is a sealed module that must be replaced in whole if there is a problem.
REPEATED EQUIPMENT FAILURES
If a specific part of the console is failing regularly, it is likely that it is being subject to unusual stresses.
Examples are;
(1) Switch or fader failure(2) Mic channel IC failure(3) Input op amp failure(4) Output op amp failure(5) Power Supply failure-
rough physical treatment
static discharge to mic
lightning, power surge, or other transient on this cable
lightning, power surge, or other transient on this cable
lightening, power surge, or other transient on the AC power line
SUGGESTED REPAIR PROCEDURES
(1) NO AUDIO OUT OF ONE INPUT CHANNEL- (Swap Cables) Be certain that the problem is in the console itself. If mic channel two doesn’t function but mic
channel one functions properly, then plug the cable from the good mic into the channel that you suspect to be bad. If the channel that you suspect to be bad
now functions, then the problem is external to the console and is in the source or the wiring. This is a very fast and easy way to test your system.
(2) VU METERS MOVE BUT NO AUDIO OUT OF THE CONSOLE- The VU meters measure the actual output of the console itself. If the meters move but no audio
is present, the problem is after the console output and is in the following signal chain. Plug a set of headphones into the output of the console and listen to the
Program output to confirm this.
(3) LOUD LOW FREQUENCY HUM IN AUDIO- Many years ago this would mean a power supply failure. In today’s electronics, this is an installation problem such
as a ground loop. To confirm the problem is not in the console, remove ALL wiring from the console and connect a pair of headphones to the output you are
testing. The hum should be absent. All wiring must be removed and headphones only used. A very common problem is for an audio power amp and speakers to
create the ground loop with the console.
(4) NO AUDIO OUT OF THE MONITORS- Be certain that the monitor system is not muted due to a mic channel being on or talkback being activated.

Opening the Console
WARNING
The console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before
beginning any type of repair or opening the console CALL Arrakis customer support for recommendations.
ACCESSING THE MOTHERBOARD
The motherboard is accessed from the bottom of the console. Four screws must be removed from the side panels (2 on each side) to have
access to the console electronics for test and IC replacement. Be careful to not scratch the console when turning the console over.
REMOVING THE MOTHERBOARD
The motherboard is attached to the front panel with screws on the bottom of the motherboard. This requires access to the inside of the console. When replacing the motherboard, be certain to replace all of the screws so that switches and faders will operate properly.
5.2
S ERVICE & M A IN TEN A N CE
Replacing Slide Faders, Switches and other parts
Slide faders and switches are soldered onto the PC board and should be replaced at the factory if at all possible.
The procedure requires proper tools, and it can be difficult to remove the parts without damaging traces or pads
on the PC board. Also, the switches are very sensitive to temperature and duration during the soldering process
and can be electronically damaged or destroyed when being soldered. If a slide fader, switch, or other part must
be replaced in the field, then extreme care must be taken.
Tools required:
1) Hand held solder sucker (stranded solder wick is not suggested)
2) Temperature controlled soldering iron with pencil tip (soldering guns should not be used)
Procedure:
1) Suck the solder from all holes until the damaged component is entirely free from the PC board. Remove the damaged part.
2) Place the new part onto the PC board. Slide faders and switches (and some other parts) ARE oriented and MUST
be replaced in the correct orientation.
3) Carefully solder the new part to the PC board.
a) Clean the tip of the soldering iron on a wet sponge.
b) Tin the tip of the soldering iron (cover the tip of the soldering iron with a small amount of solder).
c) Set the soldering iron to 734 degrees Fahrenheit (390 degrees celsius).
d) Touch the tip of the ‘soldering iron’ to the junction of the PC board pad AND the component lead.
e) Immediately touch the ‘solder’ to the junction of the soldering iron and the PC board pad.
f) Flow only enough solder to fill the hole. Immediately remove the soldering iron from the part.
g) Do not keep the soldering iron on the part for more than 2 seconds.
h) Clean the solder rosin from the PC board if required. (See Note #1 below)
Note #1: Arrakis uses aqueous core (water soluble) solder that requires the solder joint to be cleaned by water
after soldering. Aqueous core solder is acidic and must be cleaned so as to not damage the PC board over time.
Rosin core solder is not water soluble and requires a flux remover if it is to be cleaned. The rosin residue however
does not have to be removed for rosin core solder.
Warranty: Arrakis can only warranty service performed at the factory. All field service is performed at the
customer’s risk.
5.3
S ERVICE & M A IN TEN A N CE
Replacing ICs
ICs must be replaced with care. All but one IC in the console is socketed so that they can be replaced.
When replacing an IC, be careful to not bend legs under the IC or outside the socket. Be extremely careful to not shock
an IC or the motherboard with a static discharge. In some cases, you must use a grounded arm or anklet if there is a
possibility of a static discharge.
In all cases, retain the old IC because it may be found to not be damaged.

Warranty Service Procedure for the ARC console hardware
Arrakis Systems assumes that its customers have on staff (or access to) competent technical personnel and adequate test equipment.
If a product fails, Arrakis will first seek to ascertain the problem over the phone and solve it at the modular replacement 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 suspected to be at fault. If replacing PC boards does not resolve the problem, then the console is to
be returned to the factory where it will we repaired and returned to you. Repair time at the factory is normally two week days.
Shipping- The customer is responsible for payment for shipping to the factory. Parts returned to the factory freight collect will be refused. Return shipping
over and above the cost of UPS ground will be born by the customer. In the case of international shipments, all cost of shipping and duties are born by the
customer, both to and from the factory.
Under no circumstances will Arrakis replace a defective console with a replacement console.
IMPORTANT- Under no circumstances does Arrakis take any responsibility for non-factory technical expenses.
