1. GRAPHIC EQUALIZER
Each slider controls the cut (decreased gain) or boost (increased gain) for its associated frequency band. The
middle position indicates flat response (no cut or boost). Moving the slider upwards increases that frequency’s
gain, while moving it down decreases the level of that frequency.
2. PROTECTION INDICATOR
This LED indicates the state of the amplifier’s protection circuitry. When the Protection LED is on (illuminated),
the protection circuitry is active, indicating that the unit is not operating normally. This is typically due to
overheating or power limiting. Please check the Input and Output condition of the amplifier.
3. OUTPUT LEVEL DISPLAY
This 10-segment LED meter indicates the amplifier’s output level in RMS.
4. CHANNEL 1 INPUT
This is an input jack for Channel 1. Inserting a connector into this front-panel jack will override (disconnect)
the signal connected to the rear-panel CH 1 jack.
5. CHANNEL 1 - CHANNEL 5 VOLUME
These knobs provide continuous control of the output volume of Channels 1-5.
6. CHANNEL 6/PHONO VOLUME (Channel 6/CD Volume for USA/CANADA & Associated Version)
This knob provides continuous control of the volume of Channel 6 or Phono Input, as selected by the
associated rear panel switch.
7. MASTER VOLUME
This knob provides continuous control of the overall volume of the amplifier’s output signal.
