Rolls RA170 overview

  • 1Description

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.

    Rolls RA170 reviews

    RA170 Amplifier is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from Works great! Quiet, no fans. I replaced a noisy fan cooled amp with this one, and it is driving eight 70 Volt 5 Watt ceiling speakers in our church's overflow areas easily.
