If you use a separate stereo pre and power amplifier, or an amplifier where the pre and main
amplifier can be separated, connect the sub-woofer as shown. There are two alternative
methods.
A: 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 one of the mono cables. Connect one leg of the 'Y' adaptor to the Left Channel Pre
