Ashley PF-470 Powerflex Series Amplifiers
Today’s 70 Volt commercial amplification systems are likely to be a multi-zoned system requiring more than one channel or a pair of channels of amplification. Ashly's Powerflex models 470 and 670 provide four and six channels of power amplification with power ratings sufficient to drive multiple speakers and eliminate the need for external output transformers on the power amplifier.

The Powerflex-470 is a four channel amplifier capable of 4 zone operation delivering 250W per channel and the Powerflex-670 has six channels capable of a 6 zone operation with a 200W per channel rating. Channels of both amplifiers may be bridged in pairs for 140 Volt applications.

Both amplifiers use the Powerflex Series high-speed MOSFET switching design with spread spectrum switching technology and are housed in a 3RU high chassis. Modular input panels with level controls and euroblock connectors are installed on the rear panel. Speaker connections are made with screw terminal output connectors. A two speed cooling fan maintains airflow from front to back. Each channel has signal, clip, thermal and protect LEDs located on the front panel.
