The liability of the Seller under this Warranty is limited toreplacing, repairing or issuing credit (at the Seller’s discretion) for any equipment, provided that Seller is promptly notified in writing within five (5)days upon discovery of such defects by Buyer, and Seller‘s examination of such equipment shall disclose to its satisfaction that such defects existedat the time shipment was originally made by Seller, and Buyer returns the defective equipment to Seller’s place of business in Loveland, Colorado,packaging and transportation prepaid, with return packaging and transport guaranteed.B)Equipment furnished by Seller, but manufactured by another, shall be warranted only to the extent provided by the other manufacturer.C)Thermal filament devices (such as lamps and fuses) are expressly excluded from this warranty.D)The warranty period on equipment or parts repaired or replaced under warranty shall expire upon the expiration date of the originalwarranty.E)This Warranty is void for equipment which has been subject to abuse, improper installation, improper operation, improper or omitted maintenance, alteration, accident, negligence (in use, storage, transportation or handling), operation not in accordance with Seller‘s operation and serviceinstructions, or operation outside of the environmental conditions specified by Seller.F)This Warranty is the only warranty made by Seller, and is in lieu of all other warranties, including merchantability and fitness for a particularpurpose, whether expressed or implied, except as to title and to the expressed specifications contained in this manual. Seller’s sole liability for anyequipment failure or any breach of this Warranty is as set forth in subparagraph A) above; Seller shall not be liable or responsible for any businessloss or interruption, or other consequential damages of any nature whatsoever, resulting from any equipment failure or breach of this warranty.

General Repair Considerations1.6WARNINGThe console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before beginning any type of repair oropening the console CALL Arrakis customer support for recommendations.DESIGNED FOR MODULAR PART REPLACEMENTThe ARC series console is designed for modular replacement rather than repair. The power supply is external and plug in. The rotary faders are plug in. Most ICs are plug in, and a physical board layout is providedwith 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 REPAIRIf 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 mustbe 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 SUPPLYThe power supply is a sealed module that must be replaced in whole if there is a problem.REPEATED EQUIPMENT FAILURESIf 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 failurerough physical treatment(2) Mic channel IC failurestatic discharge to mic(3) Input op amp failurelightning, power surge, or other transient on this cable(4) Output op amp failurelightning, power surge, or other transient on this cable(5) Power Supply failurelightening, power surge, or other transient on the AC power lineSUGGESTED 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 fromthe 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 fastand 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 outputand 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 inthe 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 commonproblem 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.

1.7Opening the ConsoleWARNINGThe console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before beginning any type of repairor opening the console CALL Arrakis customer support for recommendations.ACCESSING THE MOTHERBOARDThe motherboard is accessed from the bottom of the console. Six screws must be removed from the bottom panel 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 MOTHERBOARDThe motherboard is attached on the top of the front panel (slide fader screws) and with screws on the bottom of the motherboard, requiring access to the inside of the console. Whenreplacing the motherboard, be certain to replace all of the screws so that switches and faders will operate properly.ACCESSING THE INTERIOR OF THE VU METER PANELThe VU meter panel is opened by removing the screw at the left and right front of the panel.ACCESS SCREWSArrakis Systems inc.

Replacing Slide Faders, Switches, and other partsSlide 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 itcan 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 duringthe 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 acidicand 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. Therosin 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.1.8

1.9Replacing Rotary FadersREMOVING THE KNOBKNOBCOVERAll 3 rotary faders are in a single wiring harness that plugs into the motherboard. Theentire harness should be replaced with all three pots. Contact the factory for a replacement harness.Pry cover fromtop of the Knobto reveal a locknut.

Replacing ICsICs must be replaced with care. Most ICs in the console are 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 PC board 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.1.10
