FRONT PANEL
The front panel does not have any controls, but only illuminated messages indicating the operation of the
amplifier.
The FRONT PANEL provides the following messages:
POWER
Three coloured (red, green, yellow) Led.
The red illumination goes ON when the main power switch is in the ON position. This indicates that the
amplifier is connected to the line supply but is in stand-by.
The green illumination goes ON when the amplifier is active by the remote control and is operating
normally. The yellow illumination goes ON when the amplifier has entered the protected state.
This implies that a fuse has blown.
WARM-UP
This led flashes while the amplifier is warming-up; during this period the operating temperature and
currents are reaching steady state conditions.
When warming-up, the amplifier is not able to express
its full sound reproduction qualities, and some background noise is normal.
The Led will be
illuminated continuously when stable operating conditions have been reached.
CD
Indicates that the CD program source has been selected.
TUNER
Indicates that the TUNER program source has been selected.
AUX 1
Indicates that the AUX 1 program source has been selected.
AUX 2
Indicates that the AUX 2 program source has been selected.
T.MON
Indicates that the signal from the tape deck has been selected.
VOLUME
The indicator goes On when a change in volume is requested with the remote control, for as long as the
volume button is pressed. When the volume is increasing the up arrow will light, and when the volume is
decreasing the down arrow will light. When the volume has reached the minimum settings, the associated
arrow will go Off, even is the remote control button is pressed.
BALANCE
The indicator goes On when a change in speaker balance is requested from the remote control. The right
arrow will go On when the left channel is attenuated, and the left arrow will go On when the right channel
is attenuated.
MUTING
The indicator goes On when the muting function is pressed on the remote control.
PROGRAM
The indicator goes On when the control microprocessor is placed in “program” mode, and can thus be
programmed from the remote control.
INFRA RED DETECTOR
All commands to the amplifier are communicated via this sensor. The infra red detector should be kept
free of obstruction, and the front of the amplifier should face towards the listening area.
REMOTE CONTROL
The remote control has the following button:
1.
CD
Press this Key to activate the amplifier and select the CD input.
2.
TUNER
Press this Key to activate the amplifier and select the TUNER input.
3.

4.
AUX 2

5.
TAPE MONITOR
