PA2 Series Dual Channel Amplifiers

PA2 Series

Dual Channel Professional Amplifiers

The PA2 Series amplifiers are dual channel power amplifiers in a single rugged chassis while providing extremely high-quality sound. The PA2 Series amplifiers are especially suited for monitor application in clubs or professional touring applications where a rugged, compact amplifier is required.

Very light weight, 250W x 2, only 8.5kg.

High power density. All channel models built with 2U high chassis with only 10 inch depth.

Compact size is excellent for touring or fixed installation applications.

Powerful, high current, low noise toroidal transformer matched with 30,000µF capacitance.

To prevent large start-up currents, a soft power-up limiter is standard on all PA-2404 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.

Dual / Parallel / Bridge Mode operation.
