Stereo or HF envelope(3)

DESCRIPTION

audio peak envelope of ‘Output Select’ mode signal

audio peak envelope of hi-fi stereo or HF envelope

Notes

1. A signal selection for output ENVOUT (pin 39) is available using bit EOS.

2. POR.

3. The selection made for mode ‘Stereo or HF envelope’ depends upon the mode of the hi-fi processing:

a) Hi-fi ‘loop-through’ mode or ‘record’ mode (bit AFM = 1): audio peak envelope of hi-fi stereo.

b) Hi-fi ‘playback’ mode (bit AFM = 0): HF envelope of left channel FM carrier.

Output Select(3)

Ext2

DESCRIPTION

line output signal is set by output select function

line output signal is EXT2L and EXT2R input

Notes

1. An independent selection of EXT2L and EXT2R inputs (pins 7 and 8) to the line outputs LINEL and LINER

(pins 15 and 16) is possible by setting bit LOS to 1. This direct selection is also operable in ‘active standby’ mode

(STBA = 1 of the control byte).

2. Using bit DOS and bits DOS1 and DOS0 of the output byte mode ‘Tuner’ or ‘Ext1’ selection to the outputs DECL and

DECR (pins 18 and 19) is offered realizing full Euro-SCART pay-TV decoder switching.
