Preliminary specification
Audio processor for VHS hi-fi
TDA9615H
Table 14
Bits IS2, IS1 and IS0; note 1
Notes
1.
Bits IS2, IS1 and IS0 select the input signal which is led to the volume controls of the hi-fi processing and generally
via the normal select function to the linear audio circuit (LINOUT; pin 20).
POR.
‘Dub Mix’ is a special selection for linear audio use supporting audio dubbing (a video recorder feature mode for
sound recording of linear audio only). ‘Dub Mix’ connects the AUX input signal to the left channel
(

AUXR) and the hi-fi output signal to the right channel (generally

hi-fi left +

hi-fi right but also
hi-fi left or hi-fi right can be selected). ‘Dub Mix’ also changes part of the ‘Output Select’ mode settings to ‘Normal’
mode for monitoring of the linear audio recording (see control bits OSN, OSR and OSL of the output byte for
‘Dub Mix’ mode input and output selection).

Bits NS2, NS1, NS0; note 1
Notes
1.
With bits NS2, NS1 and NS0 the input signal is selected which is available at the LINOUT output (pin 20) for
connection to an external linear audio circuit. The signal selected with the input select function (via
bits IS2, IS1 and IS0) is available in the following ways:
a) Left and right channel combined, optional including hi-fi volume control (

hi-fi left +

hi-fi right).
b) Left channel only (language I), optional including left channel volume control.
Furthermore the SAP input (pin 44), tuner input (pins 1 and 2) or EXT2 input (pins 7 and 8) can be selected
independently. Also a mute setting is available.
