Radio cassette players
Features
1) Adjustment of the base boost to a level appropriate
for the volume through BBS.
2) Maximum bass boost level can be set externally.
(20dB recommended)
3) Treble boost circuit (constant at 4dB) included on-
chip to preserve overall balance.
4) BBS on/off “pop” sound almost nonexistent.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions (Ta = 25 C)
