1. Power Switch
Pushing this switch up switches the unit on. Pushing it down switches the unit off.
2. Power Indicator LED
When the unit is powered on, the Power LED will glow steadily.
3. Input Attenuators
These are detented controls for regulating each channel’s input level. Clockwise
rotation increases gain.
4. Output Level Indicators
These LEDs indicate the amplifier’s output status, lighting when audio signal
reaches –30dB and –15dB.
5. Clip Indicators
The red CLIP LED indicates an excessive output level, lighting when distortion
reaches approximately 1%. Do not operate the unit with the CLIP LED steadily on
(illuminated).
6. 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.
(Note that the Protection Indicator lights for approximately six seconds when the
amplifier is first powered on.)
