Page 4: Introduction
INTRODUCTION Your MC450, MC650 or MC750 digitally controlled power amplifier represents the latest technology in control circuitry coupled to a no compromise high quality class AB power amplifier. There is no dynamic switching of the audio or power rails (a very common method of achieving extra power at the expense of audio quality) thus ensuring optimum sonic performance. -
Page 5: Connections
The minimum rating for an MC750 or MC650 should be 15 amps for 4 ohm and 20 amps for 2 ohm loads. For the MC450 it is 12 amps for 4 ohms and 15 amps for 2 ohms. -

BRIDGED (MONO) OPERATION Connect as follows : HOT Channel A Hot COLD Channel B Hot Leave both COLD connections open circuit, they are internally joined. NOTE: The load impedances change when operating in the bridged mode. (See Load/Power section below.) LOAD/POWER SWITCH 2 ohm/4 ohm In the 4 ohm position, the amplifier supply voltages are set up for loads of 4 ohms and above. -
Page 7: Limiters
Limiters The MC750, MC650 and MC450 incorporate digitally controlled signal limiters. They attenuate the signal via the same switch array as the level controls and introduce virtually no distortion. The attack time, release time, threshold level and operating mode can be set internally via the programming switches on the control PCB. -

2 ohm & Bridged LEDs These indicate the position of the switches on the rear panel. The 2 ohm LED will also illuminate if the controller senses a low impedance load (excessive temperature rise). INTERNAL CONFIGURATION SWITCHES As these can only be accessed by removing the top panel this should only be carried out by qualified personnel. -
Page 9: Remote Control Option
NEVER INCREASE THE RATING OF THE FUSE. REMOTE CONTROL OPTION The MC450, MC650, MC750 are internally wired for remote control, which is easily achieved by installing the appropriate interface/drive board during the manufacturing process, without any change to the amplifiers’... -
Page 10: Remote Control Set-Up Instructions
REMOTE CONTROL SET-UP INSTRUCTIONS To set up the remote control: Connecting the system to the controlling computer The RS485 adaptor is plugged into the back of the computer and the cable (which must be 2- core with a screen) runs from this adaptor to the 9-pin D connector on the back of the first amplifier in the sequence and then on, via 9-pin D connectors, to all other amplifiers in the system, thus creating the daisy chain link from one amplifier to the next.
