Страница: 11 / 20

Pin configuration for the XLR BALANCED INPUT connectors on the MC7104.
PIN 1: Shield or ground.
PIN 2: + input.
PIN 3:-input.
In stereo installations where the amplifier and accessory component are close to each other
and require interconnecting cables of six feet or less, using quality unbalanced connecting
cables is usually satisfactory. If the units are farther apart and require longer interconnecting
cables, using balanced cables will give extra protection from noise or interference.
9. UNBALANCED INPUTS, (2 - 1 MONO / BRIDGED)
NORMAL (Stereo) Mode: Connect shielded unbalanced cables from the unbalanced outputs
of two channels of a Preamplifier, Control Center, Remote Control System or other similar
component to UNBALANCED INPUTS, 2 and 1.
(The MODE Switch must be in the NORMAL
position).
MONO / BRIDGED Mode: Connect a shielded unbalanced cable from the unbalanced output of
a single or mono channel of a Preamplifier, Control Center, Remote Control System or similar com-
ponent to the MONO / BRIDGED 1, UNBALANCED INPUT. The UNBALANCED INPUT 2 is inactive
in the BRIDGED / MONO Mode. ( The MODE Switch must be in the MONO / BRIDGED position).
10. LEVEL, (2 - 1 MONO / BRIDGED)
NORMAL (STEREO) Mode: Adjust the individual channel level controls to the 2.5 Volt setting
when the MC7104 is used with Mclntosh Preamplifiers, Control Centers or Remote Control
Systems. For other applications you may wish to increase or decrease the settings as desired.
(The MODE Switch must be in the NORMAL position).
MONO / BRIDGED Mode: Adjust the volume level of the combined MONO / BRIDGED
channels 2 and 1, using only the MONO / BRIDGED 1 Level control. (The channel 2 Level
Control is inactive in the MONO / BRIDGED mode.) Set the control to the 2.5 Volt position when
used with Mclntosh accessory components. (The Mode switch must be in the MONO /
BRIDGED position).
11. MODE, (NORMAL - MONO / BRIDGED)
Set the MODE switch for the desired operating modes for channels 1 and 2.
12. AC POWER CABLE
Connect the MC7104 power cable to a 50/60Hz , 120 volt AC wall outlet or a Power Control
Relay. The power outlet should be capable of handling up to 8 amperes or 960 watts. Do not
connect the cable to an AC outlet on the rear panel of a Preamplifier or Control Center. The most
convenient method for turning the MC7104 power on and off is with a Power Control signal sent
to the POWER CONTROL IN connector or to the MULTI-ROOM IN connector.
13. 8A 250V SLO BLO
CAUTION: For continued protection against fire hazard, replace only with the same type 8A
(Ampere) - 250 volt SLO BLO fuse.
