preamplifier

Connect the sockets marked INPUT on the back panel of the
stereo power amplifier to the outputs from your preamplifier.
You should either use a twin-screened audio cable, or a pair of
single-screened audio cables. These cables can have a
considerable effect on the quality of the sound, and you are
advised to seek your dealer’s advice on the best type of cables
for your system.
