Mc7106 Operating Configurations; Rear Panel Features And Connections - McIntosh MC7106 Owner's Manual

The versatile Mclntosh MC7106 can be used in four different basic operating configurations.
1. Six separate 100 watt channels into 8 ohms, (160 watts into 4 ohms).
2. Four 100/160 waft channels and one 320 watt channel, bridged (8 ohms).
3. Two 100/160 watt channels and two 320 watt channels, bridged (8 ohms).
4. Three 320 watt channels, bridged (8 ohms).
The Mclntosh HT, Home Theater Series loudspeakers are 4 ohm impedance. The Mclntosh
MC7106 will deliver a total of 960 watts of power into these six loudspeakers when used in
a Mclntosh Home Theater System.
The MC7106 is designed to directly interface with a Mclntosh C39 or MX130 Audio/Video
Control Center. The connection is through a shielded 25 conductor Subminiature "D" com-
puter type cable connected from the Mclntosh Control Center to the THX INPUT connector
on the MC7106 rear panel. All six program signals as well as AC power control signals are
sent to the amplifier through this cable. Individual discrete cables can also be used if desired.
The MC7106 also is an ideal amplifier for applications requiring multi zone amplifiers. For
example, the MC7106 can supply power to a pair of speakers in three separate areas when
it is used with the Mclntosh CR10 Remote Control System.
Use high quality input and output connecting cables. Proper cables will ensure receiving
the best possible performance from your Mclntosh system. Your Mclntosh dealer can advise
you on the types and lengths of cables that will work best in your installation.
Refer to the hookup drawings for information on how to connect the inputs and outputs for
each installation configuration. Pay special attention to the polarities of the speaker hookups.
The top RED speaker output terminals are positive, and the bottom BLACK terminals are
negative or common. This configuration applies when the amplifier channels are used
individually.
In BRIDGED configuration, only the Top RED terminals are used. Follow the plus and minus
polarity indications marked above the RED terminals. When using a pair of channels in BRIDG-
ED mode, set the rear panel MODE Switch for that pair of channels to the BRIDGED position.
Use only speakers with an impedance of 8 ohms or higher with BRIDGED channels.
Refer to the numbers on the rear panel drawing for the descriptions of the MC7106 con-
nections and controls.
1. POWER (ON, OFF/REMOTE)
ON position turns the MC7106 AC power on. OFF/REMOTE allows the MC7106 AC power
to be turned on by a control signal from a Mclntosh Control Center through the 25 conductor
THX connector. The amplifier can also be turned on by a control signal fed from a Mclntosh
Control Center POWER CONTROL Output to the MC7106 rear panel POWER CONTROL IN
connector.
2. MODE (NORMAL/BRIDGED)
Set this switch to NORMAL when channels 5 and 6 are being used separately. Set the switch
to BRIDGED when the two channels are connected together for bridged operation.
3. INPUTS 5 and 6
Connect cables from a preamplifier, control center or other accessory output- to these
inputs.
