Philips Semiconductors Product specification
Audio processor with head amplifier for VHS hi-fi TDA9605H
7.5.3 NORMAL INPUT LEVEL
Fifteen settings of amplification and mute can be selected for the linear audio input signal on pin LININ. The normal input
level control can replace the manual adjustment of the playback level at the linear audio circuit.
All selections using the normal linear audio signal include the normal input level control.
Table 17 Normal input level (bits NIL3 to NIL0)
Note
1. Power-on reset state.
7.6 Input byte at subaddress 02H
The input byte is used for input selection of the hi-fi and linear audio.
7.6.1 I
NPUT SELECT
The input select function defines the input signal which is forwarded to the volume control function of hi-fi processing and
usually via the normal select function to the external linear audio circuit on pin LINOUT.
Table 18 Input select (bits IS2, IS1 and IS0)
Notes
1. Power-on reset state.
2. The dub-mix mode is a special selection which supports audio dubbing. This video recorder feature enables the
recording of the sound signal of the linear audio only (see Section 6.9).
