Standard Wiring

The main loudspeakers should be connected to the 

“A”

 terminals. Connect the Left 

Loudspeaker to the Left channel of the amplifier. Connect the Red (Positive) terminal of 
the loudspeaker to the +VE terminal of the  amplifier. Connect the Black (Negative) 
terminal of the loudspeaker to the –VE terminal of the QUAD II Classic Integrated 
amplifier. Now connect the Right Loudspeaker to the Right channel of the amplifier. 
Ensure that the Left and Right loudspeakers are connected to the Left and Right 
channels respectively.

If you have another pair of loudspeakers in a different location you can connect them to 
the 

“B”

 terminals.

Bi-Wiring

Connecting the Mains

Set the ON/OFF switch on the rear panel to the “

0

" OFF position.

Ensure that the volume control on the front panel is at the minimum (fully anticlockwise) 
position.

Plug the supplied IEC lead into the mains input socket. 

Now plug the IEC lead into the wall socket and switch on at the mains point.

Plug in the mains leads and switch on the power to your source units. The system is now 
fully connected and ready for operation.

Bi-wiring  is  a  technique  whereby  the  treble  and  bass  sections  of  a  loudspeaker  are 
independently connected to the relevant channel of the amplifier. If your loudspeakers can 
be bi-wired, you may certainly bi-wire the amplifier to the loudspeakers if you wish. Follow 
the recommendations in your loudspeaker user handbook.
