[. . . ] MC7106 SIX CHANNEL POWER AMPLIFIER MC7106 SIX CHANNEL POWER AMPLIFIER IMPORTANT SAFETY INSTRUCTIONS THESE INSTRUCTIONS ARE TO PROTECT YOU AND THE MclNTOSH INSTRUMENT. 4. Read all instructions - Read the safety and operating instructions before operating the instrument. Retain Instructions - Retain the safety and operating instructions for future reference. Follow Instructions - Follow all operating and use instructions. WARNING: TO REDUCE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS INSTRUMENT TO RAIN OR MOISTURE. 5. [. . . ] 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" computer 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. 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. When the room lighting returns to normal, the displays will also return to their normal intensity. Turn the control fully counterclockwise to turn the displays completely off. The front panel teal nomenclature retains normal illumination at all times. MODE (NORMAL/BRIDGED) Set this switch to NORMAL when channels 3 and 4 are being used separately. Set the switch to BRIDGED when the two channels are connected together for bridged operation. INPUTS 3 and 4 Connect cables from a preamplifier, control center or other accessory outputs to these inputs. LEVEL 3 and 4 Set the controls fully clockwise to the THX (1 volt) reference position when using the amplifier with a Mclntosh C39 or MX130 Control Center adapted for the Home THX® Audio System. THX® INPUT Connect a shielded 25 conductor Subminiature "D" male-to-female computer type cable from the 6 channel output connector on a Mclntosh C39 or MX130 to the MC7106 THX® input connector. This cable will supply all six output signals from the Control Center for surround sound operation. It also supplies the control signal to turn the MC7106 AC power on and off. MODE (NORMAL/BRIDGED) Set this switch to NORMAL when channels 1 and 2 are being used separately. Set the switch to BRIDGED when the two channels are connected together for bridged operation. INPUTS 1 and 2 Connect cables from a preamplifier, Control Center or other accessory outputs to these inputs. LEVELS 1 and 2 Set the controls fully clockwise to the THX (1 volt) reference position when using the amplifier with a Mclntosh C39 or MX130 Control Center adapted for the Home THX® Audio System. OUTPUTS 1 and 2, and BRIDGED OUTPUT For separate channel operation, connect the Hot lead of a loudspeaker to the + (Plus) RED upper terminal, and the Common lead to the - (Minus) BLACK lower terminal of each channel. For BRIDGED operation, connect the Hot lead of a loudspeaker to the + (Plus) RED upper Channel 1, BRIDGED terminal, and the Common lead to the - (Minus) RED upper Channel 2, BRIDGED terminal. 8 14. [. . . ] However, if a short circuit or very low load impedance is connected to any of the MC7106 outputs, destructive current levels could be reached if it was not controlled by the SENTRY MONITOR circuit- This circuit senses the dynamic operating time, voltage and current of the output stage, and controls it to safe operating limits. There is absolutely no compromise in sonic performance and it ensures safe operation of the amplifier under even the most extreme operating conditions. THERMAL CONTROL All power transistors have limits for the maximum amount of heat they can safely tolerate. The MC7106 uses highly efficient amplifying circuits which produce relatively little heat for the output power produced. [. . . ]
