PB Equalizer The gain establishment of PB-EQ considers PB output level {(internal Line Amp. + PB Amp.) = 580 mVrms} like figure 3 at the target. After replace RA and RB with a half-fix volume, adjust level. REC-EQ adjust the gain in front of input to this IC. The level digram of 1 kHz is shown figure 3. Please set "RA + RB 10 k"

Reducing pop noise is so much better 10 k to 22 k resistor to pin 14 in series and 1 F to 22 F capacitor. A mute is not built-in when doing a power ON/OFF. Please correspond to it, on the side of a set system.

REC Equalizer REC-EQ gain adjust before the input of this IC. RL needs the value more than 5.6 k based on the output at reference input. Because mode establishment resistances are built-in, REC-EQ frequency characteristics are respectively fixed value. In vase the change of the frequency characteristics are necessary, please inquire the responsible agent because the adjustment of resistors is necessary.

ALC (Automatic Level Control) ALC is the input decay rate variable system. It has internal variable resistors of pin 8 (pin 23) by REC signal that is inputted to pin 7 (pin 24). Pin 17 is detector pin. The signal input pin is pin 7 (pin 24). Resistor R1, R2 and capacitor C2, external components, for the input circuit are commended as figure 4. There are requested to use value of the block diagram figure for performance maintenance of S/N, T.H.D. etc. Figure 5 shows the relation with R1 and C1 front input point and RECOUT. ALC operation level acts for the center of +4.5 dB to standard level (453 mVrms). Then, adopted maximum value circuit, ALC is operated by a large channel of signal. ALC ON/OFF can switch it by pin 11. Please do ALC ON, after it does for one time ALC OFF inevitably, for ALC time to start usefully, in order to reset ALC circuit.
