Rolls RA170 规格指南

RA170 70 Volt-70 Watt Amplifier

The R A170 is a great problem solver for installation applications. It's a mono

70 Volt amplifier requiring no transformer coupling to drive 70 volt speakers

directly. The unit 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 has been pro-

tected from momentary shorting and excessive load by a specially designed pro-

tective circuit.

FEATURES:

• Balanced 70 volt line output

• Drives 70 volt speakers directly

• RCA or 1/4" inputs

• Spring-loaded output

• Clip indication

• Fault protected output
