3 Soft Keys 

These keys operate functions depending on the System Component Key setting.

numeric keypad: 

In 

preamp

mode the numeric keys will switch between the amplifier inputs 

(1 - cd, 2 - tuner, 3 - tape, 4 - av, 5 - aux 1, 6 - aux 2). In 

cd

mode the numeric keys will select tracks.

In 

tuner

mode the numeric keys will select tuner presets or can be used directly to input station

frequencies.

prog: 

In 

preamp mode

the 

prog

key function varies depending upon the specific amplifier model in

use. Firstly, some models incorporate a programmable volume control system that enables different
source component output levels to be matched. Secondly, some models incorporate optional
automatic source switching which will switch the input of the amplifier as soon as any handset key
appropriate to a particular source is operated. For example, if the tuner input is selected on the
amplifier and the CD 

play

key is operated on the handset, the amplifier will switch to the CD input.

Thirdly, if you have a surround sound processor connected to the A/V input, the volume control on the
amplifier can be disabled, allowing the processor to take over control of the output level from the
power amplifier stage (unity gain).

To program the volume control for each input first set the volume control to a comfortable listening
level with the loudest source (probably CD). Enter program mode by pressing and holding the 

prog

key

until the amplifier volume control indicator flashes.  Select the input to be adjusted using the handset
and use the vol 

up

and

down

keys to set the volume to a comfortable listening level. The amplifier

volume control will not rotate during this operation. Select a further input to adjust. To exit program
mode press and hold the 

prog

key until the volume control indicator stops flashing, or operate any

control on the amplifier.

To access automatic source switching enter program mode as described above.  Use the handset 

mon

key to toggle automatic switching on and off. The 

mon

button on the amplifier will illuminate when

source switching is automated. Exit the program mode as above.

To utilise the surround sound processor unity gain function, enter program mode as described above.
Use the handset 

mute

key to toggle the function on and off. The 

mute

button on the amplifier will

illuminate when unity gain is selected. Exit the program mode as above. 

The unity gain function

should only be used where the amplifier is used in a correctly configured A/V system. Damage may
result if the unity gain feature is used inappropriately.

To return to the default settings, press and hold the 

prog

key until the amplifier volume control

indicator flashes. Press and hold 

disp

key until the volume control indicator stops flashing.

In 

cd mode

the 

prog

key enables specific CD tracks and their play order to be selected. To select a play

order select a track number from the numeric keypad followed by the 

prog

key until the desired

selection is complete. During selection, the track number indicated in the player display will be
followed by either “P”, “-” or a space. “P” indicates that the track is already selected. “-” indicates that
the track can be selected. A space indicates that there is no more memory available.

The 

prog

key can also be used to delete tracks from a play order. To delete a track, press and hold the

prog

key until the 

prog

indicator in the CD display illuminates then delete the track or tracks using the

numeric keypad followed each time by a further operation of the 

prog

key. During deletion the track

number indicated in the player display will be followed by either “C”, “-” or a space. “C” indicates that
the track is already deleted. “-” indicates that the track can be deleted. A space indicates that there
is no more memory available.

The play order can be reviewed by pressing 

prog

while the player is either stopped or playing. The

player display will then scroll through the selected tracks. The 

prog

indicator on the player display will

illuminate when a play order has been programmed. To clear memory press and hold the 

stop

key.

In 

tuner mode

the 

prog

key enables specific FM station frequencies to be assigned to preset memory.

To assign a station to a preset first tune manually by inputting the station frequency directly from the
numeric keypad or by using the 

up

or 

down

keys (or 

scan

). Press and hold the 

prog

key on the handset.

The tuner is now in 

preset programming mode

- the preset indicator will flash and the display will

show “— — ”. Press the desired preset number from the numeric keypad. The display will show “— ” or
“P” if the preset number is already in use. Exit from program mode and save the new or overwritten
preset by pressing and holding the 

prog

key. To exit program mode without saving (or overwriting) a

preset, select “0 0” on the numeric keypad. To erase a preset number, select the preset and press and
hold the 

display

key. To clear all preset numbers press and hold the 

program

key followed by the

display

key.

d i s p l a y :

In 

cd mode

the 

d i s p l a y

key will scroll through these options: tracks (

“time” 

indicator off),

time (

“ t i m e ”

indicator on) and display off. In 

tuner mode

the 

display key

will simply toggle between

on and off.
