Volume  – balancing function 

 

The volume can be evenly distributed though the speakers or one channel can be louder than 

the other. To equalise the outputs of the speakers to the same volume, depress both the L & R 

balance buttons (Fig1, 4&7) on the front of the unit at the same time. 

Front Panel: 

Using either the Balance Control Right (Fig 1, 5) or the Balance Control Left (Fig 1, 2), the user 

can change the relative volume for the left and right channels.  Depressing the Right button 

will increase the volume on the right hand channel and decrease the volume on the left.   

 

To change the overall volume of the unit, use the Volume Control Knob (Fig 1, 7). Turn knob 

clockwise to increase the volume and counter-clockwise to decrease the volume.  To mute the 

system, when the speakers are balanced, continue to turn the knob counter-clockwise until the 

word MUTE

 

appears on the display, or press the Mute switch (Fig 1, 4). 

Remote Control 

Using the Function key on the remote control the user can change the relative volume for the 

left and right channels.   

 

Depress the function key once (Fig 2, 5).  The display on the preamplifier (Fig 3) will display 

BALANCE

, then use the Volume buttons on the remote control.  Depressing the - VOL button 

will increase the volume on the left and decrease the volume on the right. Depressing the + 

VOL button will increase the volume on the right and decrease the volume on the left.  

The volume can be evenly distributed through the speakers or one channel can be louder than 

the other. To balance the outputs of the speakers to the same volume, depress both the L & R 

(Fig1, 2&5) balance buttons on the front of the unit at the same time. 

 

Switching between sources 

 

To select a device, press the appropriate button on the remote control or turn the selector knob 

on the front panel until the device you require appears in the center of the display.  After a few 

seconds,  the  center  of  the  display  will  reverts  to  displaying  the  volume  level,  though  the 

selected  program  source  will  remain  on  the  lower  left  hand  corner  of  the  display.  Only 

allocated devices are available. Note: The Phono Input is always allocated. 

 

If a source is selected (either through the front panel or remote control) and the correct source 

is not selected, ensure that the program button adjacent to the input connectors for the selected 

source is illuminated.  If it is not, these input connectors will need to be re-allocated, refer to 

Connecting signal sources
