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

Therefore, it will be low-level when each pins are open. But 19 pin are mid-level when it is open.

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

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

As for internal circuit of music sensor block, music sensor out pin is connected to the collector of NPN

REC Equalizer

The outlines of REC Equalizing frequency characteristics are sh own by figure 10. Those peak level can be set up by supplying voltage. (0 V to 5 V, GND = 0 V) to 30pin (GPCAL).

And whole band gain can be set up by supplying voltage (0 V to 5 V, GND = 0 V) to 31pin (RECCAL).

Both setting up range are ± 4.5dB. In case that you don't need setting up, 30 pin, 31pin 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.

Since an output pin and an input pin for REC-EQ are adjacent, it will easily oscillate if patterns run abreast.
