CIRCUIT

8

1. LA71501BM (QIP 80 PIN): NORMAL AUDIO &  Y/C SIGNAL PROCESSING IC
1) Applicable to Multi system (PAL-GBI,MESECAM,3.58NTSC, 4.43NTSC and NAP-GBI)
2) Built-in NAP circuit to convert NTSC to PAL.
3) Normal audio signal processing circuit. (self-alignment for record bias)
4) Buit-in distinction SECAM signal circuit  (MESECAM)
5) Built-in Record and Playback FM-EQ function  (Switching the specific characteristic is possible by SERIAL CONTROL)
6) Y/C separation using comb filter
7) Built-in Input Switching circuit for 3 Video/Audio input
8) Using serial control by I

2

C-BUS 

9) Complete Adjustment free
10) Crosstalk reduction by CCD IC for exclusive use (Color Comb filter is unnecessary)

2. LA70001(2CH),LA70011(4CH),LA70020(6CH): PRE-AMP IC
1) AGC circuit is built in this IC (no record current adjustment is required)
2) Built-in the playback signal ENVELOPMENT  detection circuit for Auto tracking adjustment.

3. LC89978M: MULTI CCD DELAY LINE IC
1) Built-in Comb Filter for color noise reduction
2) Built-in 1H Delay Line for luminance circuit

1. RECORD PROCESSING
The video input signal is selected by AV 1CHIP switching IC among EXT VIDEO INPUT(28pin), LINE VIDEO
INPUT(32pin) and IF VIDEO INPUT(30pin), is supplied to the 35th pin of AV 1CHIP IC.

The input video signal is then automatically adjusted to suitale level by the built-in VIDEO AGC circuit and supplied to
SYNC separation and FBC(feedback clamp) part respectively .
SYNC signal is obtained from the composite video signal ,is supplied to the 93rd pin of MICOM and the 
11th pin of PRE-AMP IC to determine the presence of signal ,selection of PAL/NTSC and is using for SERVO control,
In PRE-AMP, is using for the HEAD-AMP switching timing and AGC circuit for self-adjustment  of the record bias.
The input signal through FBC is processed in luminance signal processing part and chrominance signal processing part
independently.
