[. . . ] C712 SYSTEM CONTROL CENTER C712 SYSTEM CONTROL CENTER IMPORTANT SAFETY INSTRUCTIONS THESE INSTRUCTIONS ARE TO PROTECT YOU AND THE MclNTOSH INSTRUMENT. BE SURE TO FAMILIARIZE YOURSELF WITH THEM. 1. Read all instructions - Read the safety and operating instructions before operating the instrument. Retain Instructions - Retain the safety and operating instructions for future reference. [. . . ] The MONO pushbutton does not affect the TAPE outputs. The total power capacity of the SWITCHED AC outlet must not exceed 1400 watts or 11. 6 amperes. To expand the AC capacity of the SWITCHED outlet, add a Mclntosh R612A or PC2 Power Controller. L and R BALANCED OUTPUTS Connect cables with XLR type Balanced Connectors from the C712, L (Left) and R (Right) BALANCED OUTPUT jacks to the balanced input jacks of a stereo amplifier, or two mono amplifiers. Signals at the BALANCED jacks are the same signals as at the Unbalanced MAIN OUTPUTS. Using balanced connectors and cables can reduce noise and interference by as much as 40dB. This extra noise reduction can be a significant improvement, especially if the cables are quite long. If two separate mono power amplifiers are used with the C712, balanced cables can eliminate the possibility of hum pickup. If cable lengths between the C712 and the power amplifiers are one meter or less, you may find high quality unbalanced cables to be adequate. - Output 7 THE REAR PANEL AND HOW TO MAKE CONNECTIONS MAIN OUTPUTS (Unbalanced) Connect shielded cables from the C712 MAIN L and R OUTPUTS to the Left and Right channel power amplifier inputs. TAPE OUTPUTS 1 and 2 These outputs provide signals to feed two separate tape recorders. The program that appears at the tape outputs is determined by the setting of the front panel INPUT switch. The TAPE COPY Switch also affects the signals at the tape outputs. Connect a cable from the C712 Left channel TAPE 1 OUTPUT to the left channel high level input of a tape recorder. Connect a cable from the C712 Right channel TAPE 1 OUTPUT to the right channel high level input of the tape recorder. Connect a second tape recorder in a similar manner, to the TAPE 2 OUTPUTS. If more than one tape recorder is connected for both record and play, make certain that the inputs and outputs of each recorder are connected to the same matching numbered inputs and outputs. PROCESSOR FROM and TO An external signal processor can be added to the C712 that will affect only the MAIN and BALANCED Outputs. The PROCESSOR-FROM jacks have built-in switching contacts to allow normal signals to pass through when no cables are connected. When an external processor is properly connected, the program signals feed to the processor from the PROCESSOR-TO jacks, and return to the C712 at the PROCESSOR-FROM jacks. Connect a cable from the left channel processor output to the C712 left channel PROCESSOR-FROM jack. Connect a cable from the right channel signal output to the C712 right channel PROCESSOR-FROM jack. [. . . ] E E (ENTER) is used with the optional RCT-2 Remote Control Translator to operate accessory equipment. MUTE Press MUTE to mute all audio outputs except those for Headphones and Tape. A Red LED above the front panel volume control turns ON to indicate that the outputs are muted. Press MUTE a second time to restore normal operation. [. . . ]
