Operating Manual - SRA-120 Power Amplifier

• Signal present indicators active but clip LED is not:

Applied input signal is distorted before it gets to the amp. Check to see if a piece of equipment in the signal chain before the amp is clipping. Normally the amplifier should be operated with input levels fully CW to maximize headroom in the signal source. Also check for damaged speaker drivers that could cause distorted sound.

If distorted sound is still heard, there may be an internal problem. Call Ashly Audio service department at 1-800-828-6308.

10.3Excessive Hiss Noise

If an excessive hiss noise is heard relative to the signal level, then the amplifier may not be getting a strong enough input signal. Push the rear panel sensitivity switch to the out position and increase the output level of the audio source which feeds into the amplifier. If excessive hiss noise is still heard, then a noisy signal is being fed into the

SRA-120. Isolate which piece of equipment in the audio chain is causing the noise. The audio source medium itself may contain the noise.

10.4Excessive Hum Noise

This is usually caused by "ground loops" in the system wiring. In a complex sound system where there are many components separated by significant distances and where several power outlets are being used, there are many opportunities for this problem to occur. If possible, feed every component in the system from one power source with a single ground point. Use balanced input and output connections between widely separated components. If a hum noise still exists, the SRA - 120 signal ground can be disconnected from its chassis ground by removing the jumper strap from the input barrier strip.

If you still need help, get in touch with your Ashly dealer, or call Ashly direct: (800) 828-6308. In New York State, dial (716) 872-0010.
