1. SENSITIVITY CHANNEL A: Use this control to adjust the input
sensitivity for Channel A.
2. CHANNEL A LED METER: Use this LED meter to monitor the
output signal level for Channel A.
3. CHANNEL A LIMIT LED: This LED illuminates when the output
signal level for Channel A triggers the internal Limit circuits. If this
LED illuminates constantly, reduce the input signal level going to the
Power Amp A Input (#18) and/or turn down the Sensitivity Channel
A control (#1).
4. LIMIT DEFEAT: The SVP1600 employs internal limit circuits to
help keep the power amplifier’s output clean at extreme volume lev-
els. (All amplifiers may begin to clip their output signals as they
approach maximum output levels, resulting in potentially speaker-
damaging distortion.) These circuits may be disabled by depressing
the Limit Defeat switch, which may result in an increase in output
power but with the possibility of distortion. Use discretion whenever
playing with the Limit circuits off.
5. CHANNEL B LIMIT LED: This LED illuminates when the output
signal level for Channel B triggers the internal Limit circuit. If this
LED illuminates constantly, reduce the input signal level going to the
Power Amp B Input (#15) and/or turn down the Sensitivity Channel
B control (#7).
6. CHANNEL B LED METER: Use this LED meter to monitor the
output signal level for Channel B.
7. SENSITIVITY CHANNEL B: Use this control to adjust the input
sensitivity for Channel B.
8. POWER INDICATOR: This lamp illuminates when the amplifier is
powered up.
9. POWER SWITCH: Use this switch to turn the amplifier on (top of
the switch depressed) and off (bottom of the switch depressed).
IMPORTANT: This unit employs forced air cooling by means of
an internal fan. The rear and side ventillation slots must
remain unobstructed when operating this amplifier. When
mounting the unit in a rack make sure there is ample room for
proper air circulation. The rack must be constructed and posi-
tioned in such a manner to allow proper air flow and the
exhausting of hot air away from the rack at all times.
