Note : 1.
If the output of sound sources is rela·
ti vely high (e.g. record player, tape recor ·
der, radio tuner, tape deck etc., which
incorporate an amp lifi er), connect them
to the AUX. IN jack.
Note : 2.
AUX. IN ja ck is separate ly circuited
wi th the vol ume control so as to mix
sounds.
Therefore the input level from
AUX. IN jack is not automatica lly
recorded.
