The SOURCE DIRECT switch is used to help improve sound
quality by selecting the shortest circuit route through the ampli-
fier that the playback signal has to travel.

The subsonic filter, MONO/STEREO MODE select circuit, tone
control circuit and balance control circuits are by-passed.
When set to OFF (SUBSONIC):

control circuit and balance control circuits.

bration during playback).
Note:
e The subsonic filter removes low frequency signals (18Hz or
lower) that are present in the playback signals.
