Effects Return Jack (EFT/RET)

The EFF/RET jack is provided to

connect an external effects

device to the MCX-106. When a

plug is inserted

t h e

internal

reverberation u n i t

is

a u t o m a t i -

cally switched out of the MCX-

106 circuitry, being replaced by the external u n i t . This jack

should be connected to the out - put of the external effects u n i t .

Nominal input level is —20dB

w i t h an impedance of 50k ohms.

Effects Output Jack (EFF)

The EFF Out jack used in con- j u n c t i o n with the EFF/RET Jack allows use of an external effects

device in place of

the i n t e r n a l

reverberation unit .

The effects

out jack should be connected to the input of the external effect unit . Nominal o u t p u t level is

l0dB with an impedance of 600 ohms.

Graphic Equalizer Input Jack (GEQ)

The GEQ i n p u t jack allows t h e

graphic equalizer to be used in-

dependently of the MCX-106

w i t h other external e q u i p m e n t ,

or the i n t e r n a l

power

a m p l i f i e r

and the

graphic

equalizer w i t h

external

equipment .

When a

plug is inserted, the main mix from the program buss is discon- nected from the graphic equal- izer and the power amplifier .

The nominal input level is —4dB

w i t h an input impedance of 50k ohms.

Power Amplifier Input Jack (PWR)

The PWR Amp i n p u t jack allows

the internal power amplifier to be used w i t h e x t e r n a l equip- ment . When a plug is inserted, the power amp is a u t o m a t i c a l l y disconnected from the MCX-106 mixer section . The nominal in- p u t level is +4dB w i t h an i n p u t impedance of 10k ohms.

Program Buss Link Jack (PGM) (+4dB 22k)

Fold Back Buss Link (FB)

(+4dB 22k)

Reverb/Effects Buss Link Jack (EFF) (+4dB 22k)

Buss Link Jacks

The buss link provides direct access to the PGM, FB, and ef- fects mixing busses, and is pro- vided for easy input expansion w i t h additional MCX-106 units or other auxiliary equipment. All jacks have an input level of +4dB with an impedance of 22k ohms.

Program Output Jack - (PGM)

The PGM Out jack is provided for connection to external equal-

izers and/or power amps, deriv-

ing its signal prior to the internal

GEQ and power amp. Nominal

o u t p u t level is +4dB with an

impedance of 600 ohms.

-Foldback Output Jack (FB) This jack is for connection to external power amplifiers and/ or equalizers for the on-stage monitoring system. Nominal

o u t p u t level is +4dB with an

impedance of 600 ohms. If the internal power amp and equal - izer are to be used for the on-

stage monitor

system, the

FB

o u t p u t

should

be connected

to

the GEQ

input

jack.

 

-Graphic Equalizer Output Jack (GEQ)

This jack allows the MCX-106 and the internal graphic equal- izer to be used with an external power amplifier, or in conjunc - tion with the GEQ in jack, to be used independently of all other

MCX-106 circuitry . Nominal o u t p u t level is +4dB w i t h an impedance of 600 ohms

Power Switch (POWER) -

The power switch is a three-

position type w i t h the middle

position being the "off" position.

The MCX-106 should be operat -

ed in the switch position which

produces the lowest amount of

system hum.

Speaker Jacks (SPEAKERS) -

The speaker o u t p u t s are stand - ard 1/4" phone jacks wired in parallel. Speaker cables (recom- mend at least #18 gauge wire) should be connected between

the MCX-106 and the speaker

systems prior to applying power

 

 

 

to the

u n i t .

 

 

 

 

 

Caution - The MCX-106 should

 

 

 

never be operated i n t o less t h a n

 

 

 

a 2 ohm speaker load.

Warning -

To

and or per-

sonnel

t h e

f u s e should

a l w a y s

be

replaced

w i t h same

t y p e and r a t i n g . Using improper

fuses will also void the warran-

Cord Wrap

The cord wrap is provided for convenient storage of the power cord when the MCX-106 is not in

use.

Caution - The power cord should

always be completely removed from the cord wrap prior to operation of the u n i t . This will insure maximum cooling of the

MCX-106. For the same reason,

adequate clearance should be m a i n t a i n e d between the rear panel and any other surface (4-6

inches should do). The vents on

the b o t t o m and top of the MCX-

106 are also provided for convec-

t i o n cooling. These vents should

be kept clear and open. Failure to

do so may cause thermal shut - down of the u n i t .

t y . The MCX-106 should always be disconnected from AC o u t l e t prior to changing fuses. If fuse

repeatedly

f a i l s , the u n i t

should

be referred

to q u a l i f i e d

service

personnel lor repair .
