Rolls RA170 Rack Mount 70V 70 Watt 1U Power Amplifier

The RA170 Power Amplifier was designed especially for the installation contractor. The RA170 is a single rack-space- mono unit with a choice of an RCA or 1/4- unbalanced input. The 70 volt speaker outputs are provided via spring-loaded terminals - no transformer is required for speaker connection. The front panel includes a Power indicator LED- a Volume control- and two Clip LEDs which indicate circuitry overload. The output circuitry is protected from momentary shorting and excessive load by a specially designed protective circuit. 70 Watts of clean amplification into 70 V system.Spring-loaded output terminals.Front-panel heat sinking.Specifications:Recommended Load: 70 Volt line (70 Watts maximum).Frequency Response: 70Hz to 20 kHz.Equiv.
