Introduction
This top of the range, no-compromise, ultra-high quality and professional power amplifier has a sonic performance that is comparable to the very best hi-fi amplifiers, only much more powerful. Since its introduction in September 1996, the MC1250 has been extremely successful in the discotheque and night-club market all over the world, where it has proved itself capable of maintaining its high performance levels in the most demanding conditions.
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 MC1250 to be run flat out, all night in the most arduous of conditions, such as in a hot discotheque or night club, 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.
Features
- Complementary class AB bipolar outputs, with unique floating drive stage for optimum audio performance.
- 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.
- No dynamic switching of audio outputs or supply voltages.
- 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. Levels are matched to within 0.2dB at all positions.
- Optional crossover cards available. 24dB/Octave Linkwitz Riley.
- Fully functional bi-directional remote control via RS485 available.
- "2 ohm" and "bridged mode" indicators on front panel.
- Modular construction with proprietary heat sinks for ease of serviceability.
- 1250 watts per channel into 4ohms using dynamic signals (signal dependent).
- Soft start "power on" sequence with full inrush protection.
- Full DC and short circuit (serious fault) protection which automatically reconnects when the fault is cleared. Front panel LEDs indicate fault condition.
