Features

• REC equalizer is very small number of external parts and have 4 types of frequency characteristics

built-in.

• 2 types of input for PB, 1 type of input for REC.

• 70µ - PB equalizer changing system built-in.

• Dolb y NR*

Unprocessed signal output available from recording out terminals during PB mode.

• Provide stable music sensor system, available to design music sensing time and level.

• Controllable from direct micro-computer output.

• Bias oscillator control switch built-in.

• NR ON / OF F and REC / PB fully electronic control switch ing built-in.

• Normal-speed / high-speed, Normal / Crom and PB equalizer fully electronic control switching built-in.

• Available to reduce substrate-area because of high integration and small external parts.

Notes: 1. Each pins are on pulled down with 100 kΩ inter nal resi stor.

Therefore, it will be low-level when each pins are open.
But pin 24 is mid-level when it is open.

2. Over shoot level and under shoot level of input signal must be the standardized (High: V
Low: −0.2 V).

3. For reduction of pop noise, connect 1 µF to 22 µF capacitor with mode control pins.
But it is impossible to reduce completely in regard to Line mute, therefore, use external mute at
the same time.

Both setting up range are ±4.5 dB. In case that you do not need setting up, pin 10, pin 11 should be open

Note: Depending on the employed REC/PB head and test tape characteristics, there is a rare case that the

Automatic Level Control

ALC is the input decay rate variable system. It has internal variable resistors of pin 55 (pin 44) by
RECOUT signal that is inputted to p in 9 (pin 34 ) .

The operation is similitude to MS, detected by pin 13.

The signal input pin is pin 56 (pin 43). Resistor R1, R2 and capacitor C2, external components, for the
input circuit are commended as figure 12. There are requested to use value of the block diagram figure for
performance maintenance of S/N, T.H.D. etc.

Figure 11 shows the relation with R1 front RIN point and ROUT.

ALC operation level acts for the center of +4.5 dB at tape position TYPE I and the center of +2.5 dB at tape
position TYPE II, to standard level (300 mVrms).

Then, adopted maximum value circuit, ALC is operated by a large channel of a signal.

ALC ON/OFF can switch it by pin 15. Please do ALC ON, after it does for one time ALC OFF inevitably,
for ALC time to start usefully (when switching PB → PASS, when switching PB → PASS), in order to
