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.\u003c\/p\u003e\r\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eRecommended Load: 70 Volt line (70 Watts maximum)\u003c\/li\u003e\r\n\u003cli\u003eFrequency Response: 70Hz to 20 kHz\u003c\/li\u003e\r\n\u003cli\u003eEquiv.
