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: VCC, Low: − 0.2 V).

3.For reduction of pop noise, connect 1 µ F to 22 µ F 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.

Music Sensor Output (MSOUT)

As for internal circuit of music sensor block, music sensor output pin is connected to the collector of NPN type directly, output level will be “high” when sensing no signal. And output level will be “low” when sensing signal.

Connection with microcomputer, it is requested to use external pull up resistor (RL = 10 kΩ to 22 kΩ ) Note: Supply voltage of MSOUT pin must be less than VCC voltage.

REC Equalizer

The outlines of REC Equalizing frequency characteristics are shown by figure 9. Those peak level can be set up by supplying voltage. (0 V to 5 V, GND = 0 V) to pin 10 (GPCAL).

And whole band gain can be set up by supplying voltage (0 V to 5 V, GND = 0 V) to pin 11 (RECCAL).

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

Note: Depending on the employed REC/PB head and test tape characteristics, there is a rare case that the REC-EQ characteristics of this LSI can not be matched to the required characteristics because of built-in resistors which determined the REC-EQ parameters in this care, please inquire the responsible agent because of the adjustment of built-in resistor is necessary.

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 pin 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 reset ALC circuit.
