Power and style that amplifies

The PA660.4 is a four-channel class A/B amplifier with built-in fully variable low-pass crossover. Equipped with remote gain, the PA660.4 is capable of two-channel operation with a maximum power of 600 Watts when both the front and rear bridged channels are driven into 4 ohms speaker loads.

PA660.4 Features:

75 Watts x 4 continuous, 85 x 4 dynamic power (2 ohm load), 4 channel mode.

150 Watts x 2 (4 ohm) continuous power, 2 channel mode.

CEA-2006 compliant specifications for true, accurate power ratings.

4-channel, dual bridge-mono (2-channel), or dual simultaneous stereo/mono operation provide a variety of configurations and setups: 4-channel for front and rear speakers; 2 speakers and a sub; 2 subwoofers

2 ohm stable 4-channel operation.

High-speed MOSFET switching power supply and high current bipolar output transistors pump maximum voltage and high current to your speakers or subwoofers.

Double layer fiberglass epoxy printed circuit boards for more rigidity, less shrinkage and a smaller overall amp footprint.

6-way Smart System Protection (SSP) circuits

Variable bass boost (0dB, +8dB) for extra bass thump.

Variable input gain optimizes match with different signal sources (250mv to 8V).

RCA outputs (front channels only) for easy daisy chaining of other amplifiers.

Mounting hardware with rubber isolation grommets and extra fuses included.

 

Multi-color status LED gives instant information on amplifier operation.
