How does it work?
Power on
Use the mains switch on the back of the amplifi er to turn it on. The amplifi er is now in standby mode.
Standby
The amplifi er can enter standby mode only by pressing on the remote control. Only the microprocessor and the standby LED are
powered during standby. Therefore, the AMP-150 has an ultra-low standby power consumption of less than 1W.
Reactivate the amplifi er by pushing the on the remote control again or pressing the heat or mute button on the amplifi er itself.
Heat
By pressing the heat button you will quickly warm up the amplifi er to the optimal temperature. This process would otherwise normally
take up to 2 hours, but the pre-heating feature reduces this period to about 15-30 minutes at normal room temperature. The heat
indicator will turn off when the optimal temperature has been reached. You will fi nd the pre-heater button on the front panel between
the input selection knob and the display.
Adjusting the volume
Turning the volume control knob clockwise increases the volume. Turn it
counter-clockwise to decrease the volume. The front panel analogue meter
displays the volume level.
Input selection
Use the input selection knob to select input channel. You can turn the input
selection knob both clockwise and counter-clockwise endlessly. See the order
of the input channels when turning the knob in the two fi gures on the right.
Display dimming
The display backlight can be dimmed by a trimmer on the rear panel. Use a
small screwdriver and turn it clockwise to increase light intensity or turn it
counter-clockwise to dim it.
Muting
For complete silence simply press the mute button. The selected input channel indicator will blink when muted. Press the mute button
once more to return to the previous volume level. The button is located between the display and the volume knob.
Direct
The direct function bypasses the volume control turning this amplifi er into a power amplifi er. This can be very useful in surround setups.
To activate this mode, select the tape input and press and hold the mute button on the amplifi er for 2 seconds. The amplifi er is now
muted and an indicator will show that the function has been activated. Press the mute button on the amplifi er to disable muting.
To disable the Direct function, press and hold the mute button on the amplifi er again for 2 seconds. The Direct indicator will turn of
and the Direct mode is now disabled. Press the mute button on the amplifi er again to restore normal listening mode.
This function can only be enabled and disabled on the amplifi er itself.
