USER INSTRUCTIONS: WH-D8 & WH-D10 SUBWOOFER
A/V Processor Connections
Your subwoofer has been designed for optimum
performance with a digital processor. If your A/V
processor has a line level or LFE subwoofer output you
should use this connection. You will need to purchase
a single screened RCA phono lead from your dealer.
Connect this lead to the LFE input of the subwoofer as
shown.
Alternatively, you may use a split mono lead from the
processor to Line Inputs of the subwoofer. In this case
the input level at the subwoofer will be slightly higher.
Stereo Line Output Connections
If your amplifier has a spare preamplifer output or a
stereo subwoofer output, connect the subwoofer as
shown. You will need a stereo screened RCA phono
cable.
Pre Out – Main in Connections
If you use a stereo pre and power amplifier, or an
amplifier where the pre and main amplifier cab be
separated, connect the subwoofer as shown. There are
two alternative methods.
You will need two screened RCA 'Y' adaptors and two
single RCA phono cables.
Remove the Pre-Main links on your amplifier. Connect
the socket (common) of an RCA 'Y' adaptor to the Left
Channel Pre Out socket on the amplifier and the other
leg to the Left Channel Main In socket. Connect the
remaining plug on this combination to the Left Channel
Line Level input on the subwoofer. Repeat this for the
Right Channel.
