Introduced in October 1997, this technologically innovative,
digitally controlled amplifier has been designed to be used in studios,
clubs and a wide variety of fixed installations. The unique current
driven drive stage adds an extra dimension to the bass dynamics, ensuring
very accurate reproduction of transients coupled with a natural 'openness'
not usually found in amplifiers of this type. The sophisticated microcontroller
ensures that this performance is maintained over a wide range of temperatures
and loads.
The heatsinks have been specifically designed to maximize efficient
heat exchange allowing the MC750 to be run flat out, all night in the
most arduous of conditions, without shutting down or cutting out.
Despite the sophistication of the amplifier, its modular design makes
it remarkably easy to work with and it also has the option of a remote
control facility.
- Complementary class AB bipolar outputs, with unique floating drive
stage for optimum audio performance.
- No dynamic switching of audio outputs or supply voltages.
- Sophisticated monitoring of load, temperature and operating parameters.
If overheating occurs, the power supply is reduced to a safe level
- protecting the unit without shut-down.
- Low noise vari-speed fans for quiet operation.
- User selectable clip limiter with "tight" and "easy"
settings which track the supply voltages.
- Accurate Peak Level Meters indicating headroom, which automatically
adjust to power supply and load.These double as level control position
indicators when adjustments to level are made.
- Mute switches with fade up on release. The "power on"
sequence also starts in "mute" and fades the signal up to
the previous setting, after checking the system.
- Level controls can be separate or linked. In "linked mode",
adjustments are relative (both channels change by the same amount
in dBs).
- "2 ohm" and "bridged mode" indicators on front panel.
- Full DC and short circuit (serious fault) protection which automatically
reconnects when the fault is cleared. Front panel LEDs indicate fault
condition.
- Modular construction with proprietary heat sinks for ease of serviceability.
- 750 watts per channel into 4ohms using dynamic signals (signal dependent).
- Optional crossover cards available. 24dB/Octave Linkwitz Riley.
- Fully functional bi-directional remote control via RS485 available.
- Soft start "power on" sequence with full inrush protection.
- Full 5-year warranty.
