Attention!

This console contains static sensitive devices:

Normal precautions against static discharge should be observed when

handlingindividualmodules.Inparticular, modulesbeingpackedforshipping

for return or repair must be packed in special static protection bags before

packaging. Damage caused by static discharge may not be covered under

warranty.

Replacing Modules in a Powered-up Console:

While in an emergency situation it is possible to remove and insert modules

on a powered-up console, Auditronics does not recommend this procedure.

Whenever possible it is best to power down the console first before removing

or replacing modules.

However, if you find you must proceed with this operation, then be sure to

take the following precaution:

When re-inserting a module, take care to replug it squarely into its

mainframe connector socket, so all edgecard fingers make contact

simultaneously. In other words, the gold-plated bus connector fingers on the

bottom edge of the module's printed circuit board must be inserted squarely

(i.e., perpendicular) to the mating socket on the bottom pan of the console

mainframe. The intent is to prevent a situation where one of the module's

power pins makes significant contact before the others. (Naturally, this

same precaution must be taken when using extenders.)

Iftheaboveinstructionsarefollowedtheprocedureshouldberoutine;ifthey

are not, you could run the risk of damaging the console's logic chips.

Again, to avoid ANY possibility of this damage, whenever possible we

stronglyrecommendpoweringdowntheconsolebeforereplacinganymodules.

Installation and Power

CountertopMounting

The 220 digital audio console is designed for countertop drop-in

mounting. Console placement should avoid proximity to any electro-

magneticfields,suchaslargepowertransformers,motors,andfluores-

centlightingfixtures.Therequiredcut-outwidthis371/4”andcut-out

front-to-back dimension is 19”. The front of the console will extend

approximatelyoneinchforward ofthe cut-out.The console’swooden

sidepieces will extend about 7/8” on either side of the cut-out width.

Clearances

Note the two module extractor tools (black thumbwheel screws)

mounted in the front surface of console’s lower mainframe pan (just

above and to the left of the righthand headphone jack). These must be

removed before lowering the console into its cutout!

Once in place the console mainframe pan will extend approxi-

mately 5/8 inches below the countertop surface. Note the hinged

meterbridge will require 15” above the countertop surface to open

freely. When fully open the meterbridge will extend 5 1/2” behind the

rear line of the cut-out. When closed, the meterbridge will extend

2 1/4” behind this rear cut-out line and 8 1/8” above the countertop

surface.

Do not connect the 220 console to its power supply (and do not

connect the power supply to the AC power line) until instructed to do

so.

System Ground

The first step is to ground the console.

Note that as supplied from the factory, console rackmount power

supply common, audio ground, and the 220 mainframe are connected

togetherattheconsole,butareNOTconnectedtoelectricalgroundand

the chassis of the power supply. Safety requirements dictate that a

positiveconnectionfromtheconsolemainframetoelectricalgroundbe
