Description
The RA170 mono power amplifier was designed especially for the installation contractor, and is housed in a single rack-space unit with a choice of either an RCA coaxial or 1/4 TS phono unbalanced input. The 70 volt speaker outputs are provided via spring-loaded terminals and no transformer is required for speaker connection.
The front panel includes a power indicator LED, a volume control, and two clip LED's which indicate circuitry overload. The output circuitry of the RA170 is protected from momentary shorting and excessive load by a specially designed protective circuit.
Features:
- Mono 70 volt amplifier
- Drives 70 volt speakers directly
- Choice of RCA coaxial or 1/4 TS phono input
- Spring loaded speaker output
- Clip indication
