1. CH1 volume control
In bridge mode, this attenuator controls the volume of two channels. CH2 attenuator has no function.
In stereo or parallel mode, this attenuator just controls CH1 volume.
Gain control range: -8 ~, continuous control.
Gain control range: -8 ~ 0dB, 40 steps control, effective rotation angle is 280 degrees.
2. Protection LED
The Protection LED indicates that one or more critical issues require your attention. The amplifier is
protected against overheat, overload, DC and short circuit. When the LED is lit, check the amplifier for
these problems and provide an adequate solution.
3. Over-heat indicator
The over-heat LED will light when the internal temperature of the amplifier exceeds 105 degrees Celsius.
At the same moment, the over-heated channel might automatically be switched off in order for the
amplifier to cool down. When the over-head LED is lit, be sure to check the air circulation at the front
and the back of the amplifier.
4. Clip indicator
The Clip Indicator LED will light when over-modulation of the audio signal is detected. Although the
amplifier has a built-in clip limiting circuit, any illumination of the Clip indicator LED indicates that the
input level should be reduced.
5. Signal indicator
The signal LED indicates that an audio signal is present at the amplifier input. The sensitivity of this LED is
0,35V or -9 dB. Illumination of this LED indicates correct functioning of the device.
6. Power LED.
Indicates that AC power is connected and the amplifier is turned on.
7. CH2 volume control
In bridge mode, this attenuator has no function, the volume is controlled by CH1 attenuator .
In stereo or parallel mode, the attenuator just controls CH2 volume.
Gain control range: -8 ~ 0dB, 40 steps control, effective rotation angle is 280 degrees.
8. AC Power Switch.
This is the main Power switch. Press to turn the amplifier on.
9. Parallel indicator
When this LED is lit, means the amplifier is working in parallel mode .
10. Bridge indicator
When this LED is lit, means the amplifier is working in bridge mode.
11. Air entrance
Don't obstruct or insert objects into air vents.
12. Standby power indicator
The stand-by LED indicates that the amplifier is in Stand-by mode. When the amplifier is switched on,
the stand-by LED will stay illuminated for a few seconds, during which a self-test is performed. When
the self-test is completed, the stand-by LED dims.
13. Handles
Handles are used for easy transportation.
