Switching the unit on 

 

Switch the main power switch to On. 

 

When the unit is switched on at the main power switch (Fig 6, 6) the pre- amplifier will go into 

Standby mode. 

 

Switch the unit on by pressing the Standby/On button on the unit or the remote control.  To 

return the unit to Standby mode press the Standby/On button again. 

Note:  To continue the set up process, the unit must be On, not in Standby. 

 

Allocating signal sources and the remote control 

 

All inputs must be allocated using the remote control (Fig 7).   

Note

: The Phono selection is 

permanently allocated to the Phono inputs. 

 

Once  the  signal  source  units  (e.g.  CD  player)  have  been  connected  to  the  input  connector 

terminals (Fig 6, 7) at the rear of the preamplifier, ensure that the preamplifier is On, not in 

Standby mode. 

 

Depress  the  applicable  program  button  (situated  above  the  connectors)  and  simultaneously 

point the remote control to a remote sensor window and press the button on the remote control 

which best describes the signal source unit you have connected. 

 

The program button will flash twice and will remain illuminated, indicating that this pair of 

input connectors are now allocated to the selected signal source unit.  Repeat this process for 

all signal source units (maximum 5 plus Phono). 

 

If the device label that is being depressed on the remote control has been previously allocated 

to another connector pair, this pair will now be de-allocated. 

 

De-allocating Program Buttons 

 

Note: Ensure the location being de-allocated is not the currently selected input, the currently 

selected input can not be de-allocated. 

 

Press and hold the applicable program button and simultaneously point the remote control to 

a remote sensor window and press the Mute button.  The Program Button will flash twice and 

then  remain  off.    This  input  has  now  been  de-allocated  and  can  be  used  for  another  signal 

source unit.
