Rolls RA170 70 Volt Mono Installation Power Amplifier
Please Note: Orders will not be available for shipment until on or about Wednesday August, 19.
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
- Fault protection output
