PA4 Series

4-Channel Professional Amplifiers

The PA4 Series amplifiers combine 4 discrete high-power amplifiers in a single rugged chassis while providing extremely high-quality sound. The PA4 Series amplifiers are especially suited for monitor application in clubs or touring applications where a rugged, compact amplifier is required.

 Very light weight, 250W (rms) x 4, only 12.5Kg.

 High power density, only 10" deep. All four channel models built with 2U rack high chassis.

 Compact size is excellent for touring or fixed installation applications.

 4 Independent Channels or Dual Bridge Mode (Hi-Power) operation.

 Powerful, high current, low noise toroidal transformer matched with 60,000µF capacitance.

 To prevent large start-up currents, a soft power-up limiter is standard on all models.

 Ultra-low distortion (<0.01%) circuitry and high current output stage for punch.

 Switchable limiter reduces clipping distortion and protects speakers from being overdriven.

 Selectable high pass filter 35 or 70Hz, prevents woofer speaker over excursion or when full band-width is not required.

 Balanced XLR input and two balanced TRS phonejacks for cascading amplifiers.

 Quiet, auto-variable speed fan, forced air cooling system.

 Detent volume controls.
