SOURCE DIRECT switch
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.
When set to DIRECT:
The subsonic filter, MONO/STEREO MODE select circuit, tone
control circuit and balance control circuits are by-passed.
When set to OFF (SUBSONIC):
The playback signal is routed through the subsonic filter, tone
control circuit and balance control circuits.
During record piayback this position can be used to reduce ultra
low frequency noise, rumble, hum ete. (indicated by woofer vi-
bration during playback).
Note:
e The subsonic filter removes low frequency signals (18Hz or
lower) that are present in the playback signals.
