AMPLIFICADOR ETAPA DE POTENCIA 250W X 4 (4 OHM) - MC2 (T4-250)

Designed for use in multi-zone installations, where sonic quality and reliability are the highest priorities. The T4-250 is a 4 x 250W amplifier housed in a 2U chassis and has been designed with complementary AB bipolar outputs, using the unique MC2 current driven floating drive stage and conventional analogue level controls.

The sound quality is maintained over a very wide range of load and temperature conditions. Sophisticated 'side chain' limiters prevent distortion and speaker damage but are out-of-circuit until the onset of clipping.

The control circuitry provides full protection against short circuits, DC and excessive temperature together with inrush current limiting and delayed 'turn on'.
-Complementary class A/B bipolar outputs, using the unique MC2 current driven floating drive stage, which gives one of the 'cleanest' sounds available.
-Sophisticated monitoring of amplifier temperature and load conditions.
-Proprietary control and protection circuitry continuously checks for all fault conditions such as shorted outputs, DC on outputs, excessive temperature (blocked air flow), component failure etc… and disconnects the outputs, if such an event occurs.
-Low noise vari-speed fans.
-Side-chain' clip limiter prevents speaker damage from clipped signals but only comes into the signal path during limiting, and is inaudible during normal operation.
-Audio 'fade-up' on Power-on.
-Optional internal crossover cards available.
-New proprietary 'Ultra Cool' heatsink.
-Full mains inrush protection.
-Full 5-year warrant
