Inputs and Outputs
For adding or removing connections your AMP IV must be switched off!
Please make sure that all cables are in absolute best condition. Bro-
ken shields or short-cut loudspeaker cables could damage loud-
speakers or the amplifier!
At first connect your AMP IV to your pre amplifier. The inputs are sub-
divided into the groups "
Right Group
" and "
Left Group
". Within both groups
are two input jacks each ("
IN 1R
" & "
IN 2R
" and "
IN 1L
" & "
IN 2L
").
If you want to use the AMP IV as a 4 channel power amplifier flip both
switches "
Input Source
" into position "
Right Multi
" and "
Left Multi
".
In case you want to use the AMP IV as a bi-amping power amplifier in
stereo mode flip the switches "
Input Source
" into position "
IN 1R
" and
"
IN 1L
". Connect the outputs of your pre amplifier to inputs "
IN 1R
" and
"
IN
1L
".
Both modes are selectable separately to both input groups. For example,
you can use "
Group Right
" with its inputs for both surround channels "Left
Surround" and "Right Surround" (switch position "
Right Multi
"). The left
group can be used to setup a Center speaker in bi-amping mode (switch
position "
bi-amp IN 1L
").
Connect your speakers to the gold plated WBT terminals at the back.
Please make sure that the red outputs (+) of the amplifier are connected to
the positive inputs of the loudspeakers (usually red) and the white outputs
(-) are connected to the negative loudspeaker inputs (usually white or
black).
Wrong speaker polarization will result in severe loss of sound quality!
The nominal loudspeaker impedance should be 4 ohms or higher.
Although the AMP IV has a protection circuit to prevent damage of the
system, switch off the unit while working on the loudspeaker cables.
