KA22296 DOUBLE DECK SYSTEM FOR RADIO CASSETTE
4. Outside Input
This product is so designed to accomdate 3 types of outside input and 3 paired input terminals are
also present too. It is possible to use each of them independently and their selection lies within
the switch output condition of table 1,2. Under the condition of usage it is wise to be aware of
situations since it could be inputed through reduction from outside. Take it as a reference when input
impedance is reduced to approximately 30
§ú
, especially the input dynamic range is 0.6Vrms.
The input monitor output gain is 6dB, and take it into an account that record output
’
s gain is 26dB.
5. Mic Input
The MIC amplifier
’
s advantage is 20dB. Attention MIC input signal level at MIC mixing mode or another input signal with mixing
input signal can reduce because of ALC operating from excessing MIC input signal.
