If mic cha
36、nneltwo 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 console and is in the source or the wiring. This is a very fast
37、 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 following signalchain. Plug a set of headphones into the
38、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 confirm the problem is not in the console, remove ALLwir
39、ing 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 ground loop with the console. (4) NO AUDIO OUTOFTHE MONITORS-
40、Be certain that the monitor system is not muted due to a mic channelbeing on or talkbackbeing activated. 6.1 SERVICE & MAINTENANCE Opening the Console WARNING The console should be repaired by qualified, professional, & experienced, audio technicians ONLY. Before beginning any type of repair or open
41、ing the console CALLArrakis customer support for recommenda- tions. 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 con- sole electronics for test and IC replacement. Be carefulto not scratch t
42、he 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 motherboard, be certain to replace allof
43、 the screws so that switches and faders will operate 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 6.2 Arrakis Systems inc. SERVICE & MAINTENANCE Replacing Slide Faders, Switches, and oth
44、er 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 to temper
45、ature 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 suggested)
46、 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 dam- aged part. 2)Place the new part onto the PC board. Slide faders and switches (and some
47、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 smallamount of solder). c)Set the solderin
48、g 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. Immediately rem
49、ove 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 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:Arra
