POWER SWITCH
1
press to toggle the power on or off.
PROTECT
2
By overheat or when DC is occured at power amp blocks, protection cirquit is activated and „protect" -LED
turns red. The protection cirquit and LED is always activated for 3 seconds after you turn the amplifier on.
LIMIT
3
Lights up orange when the output signal distortion on the corresponding channel rises above 1% -indicating
that"clipping"has occurred because the signal level is too high. In this case lower the Gain.
SIGNAL LED
4
Normal indication: The Signal indicator illuminates when the input signal exceeds -35dB, the -15dB indica-
tor illuminates when the signal exceeds -15dB, the -10dB indicator illuminates when the signal exceeds
-10dB, the -5dB indicator illuminates when the when the signal exceeds -5dB.
If no iddication: check gain settings and increase gain if necessary. Check input conn
-ections and audio sourece for signal. If the Clip LED illuminates with little or no Signal
Indication, check the output wiring for shorts.
Abnormal indication: if -20dB, -15dB, -10dB, -5dB LED illuminates with no signal
input, there may be system oscillations or some other malfunction. Disconnect the load
and fully reduce the gain. If the LED remains on , the amp may need servicing.
GAIN CONTROLS
5
Turn the gain controls clockwise to increase gain and counter clockwise to decrease gain.
The maximum voltage gain of the amplifier varies depending on the model is shown of the
designation. The Gain controls are marked in dB of attenuation.There are 21 steps in Gain control for
adjustments. The upper 14 steps are about 1dB each, and settings should normally be
made within this range. The range below -14 dB should not be used for normal program
levels.
