C AU TI O N 1.4 Warranty This console carries a manufacturer s warranty subject to the following guidelines and limitations: A)Except as expres

13、sly excluded herein, Arrakis Systems inc. (“ Seller” )warrants equipment of its own manufacture against faulty workmanship or the use of defective materials for a period of one (1)year from date of shipment to Buyer. The liability of the Seller under this Warranty is limited to replacing, repairing

14、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 shalldisclose to its satisfaction that such defects existed at the time shipm

15、ent was originally made by Seller, and Buyer returns the defective equipment to Seller s place of business in Loveland, Colorado, packaging and transportation prepaid, with return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, shallbe warranted only

16、 to the extent provided by the other manufacturer. C)Thermalfilament 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 shallexpire upon the expiration date of the original warranty. E)This Warra

17、nty is void for equipment which has been subject to abuse, improper installation, improper operation, improper or omitted mainte- nance, alteration, accident, negligence (in use, storage, transportation or handling), operation not in accordance with Seller s operation and service instructions, or op

18、eration outside of the environmentalconditions specified by Seller. F)This Warranty is the only warranty made by Seller, and is in lieu of allother warranties, including merchantability and fitness for a particular purpose, whether expressed or implied, except as to title and to the expressed specif

19、ications contained in this manual. Seller s sole liability for any equipment failure or any breach of this Warranty is as set forth in subparagraph A)above; Seller shallnot be liable or responsible for any business loss or interruption, or other consequentialdamages of any nature whatsoever, resulti

20、ng from any equipment failure or breach of this warranty. 1.5 General Repair Considerations WARNING The console should be repaired by qualified, professional, (1) Switch or fader failure-rough physicaltreatment (2) Mic channelIC failure-static discharge to mic (3) Input op amp failure-lightning, pow

21、er surge, or other transient on this cable (4) Output op amp failure-lightning, power surge, or other transient on this cable (5) Power Supply failure-lightening, power surge, or other transient on the AC power line SUGGESTED REPAIR PROCEDURES (1) NO AUDIO OUTOFONE INPUTCHANNEL- (Swap Cables)Be cert

22、ain that the problem is in the console itself. If mic channeltwo doesn t function but mic channelone functions properly, then plug the cable from the good mic into the channelthat you suspect to be bad. If the channelthat you suspect to be bad now functions, then the problem is externalto the consol

23、e and is in the source or the wiring. This is a very fast and easy way to test your system. (2) VU METERS MOVE BUTNO AUDIO OUTOFTHE CONSOLE- The VUmeters measure the actualoutput of the console itself. If the meters move but no audio is present, the problem is after the console output and is in the

24、following signalchain. Plug a set of headphones into the output of the console and listen to the Program output to confirm this. (3) LOUD LOWFREQUENCYHUM 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

25、 confirm the problem is not in the console, remove ALLwiring from the console and connect a pair of headphones to the output you are testing. The hum should be absent. Allwiring must be removed and headphones only used. A very common problem is for an audio power amp and speakers to create the groun

26、d loop with the console. (4) NO AUDIO OUTOFTHE MONITORS- Be certain that the monitor system is not muted due to a mic channelbeing on or talkbackbeing activated. 1.6 Opening the Console WARNING The console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before b

27、eginning any type of repair or opening the console CALLArrakis customer support for recommendations. ACCESSING THE MOTHERBOARD The motherboard is accessed from the bottom of the console. Sixscrews must be removed from the bottom panelto have access to the console electronics for test and IC replace-

28、 ment. Be carefulto not scratch the console when turning the console over. REMOVING THE MOTHERBOARD The 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. When replacing the motherb

29、oard, be certain to replace allof the screws so that switches and faders willoperate properly. ACCESSING THE INTERIOR OFTHE VU METER PANEL The VUmeter panelis opened by removing the screw at the left and right front of the panel. ACCESS SCREWS Arrakis Systems inc. 1.7 Replacing Slide Faders, Switche

30、s, and other parts Slide faders and switches are soldered onto the PC board and should be replaced at the factory if at allpossible. 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

31、 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 wickis not

32、suggested) 2)Temperature controlled soldering iron with penciltip (soldering guns should not be used) Procedure: 1)Suckthe solder from allholes untilthe 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 (a

33、nd some other parts)ARE oriented and MUSTbe 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 smallamount of solder). c)Set the s

34、oldering iron to 734degrees Fahrenheit (390degrees celsius). d)Touch the tip of the soldering iron to the junction of the PC board pad ANDthe 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 fillthe hole. Immediat

35、ely 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 #1below) Note #1: Arrakis uses aqueous core (water soluble)solder that requires the solder joint to be cleaned by water

36、 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 fluxremover if it is to be cleaned. The rosin residue however does not have to be removed for rosin core solder. Warranty:Arrakis can

In some cases, you must use a grounded arm or anklet if there is a possibility of a static discharge. In allcases, retain the old IC because it may be found to not be damaged
