Since amplifier ch1 and ch2 are used as a NAB equalizer amplifier at playback, a time constant circuit is established in the NF section (1-11pin, 7-10pin) to obtain NAB characteristics. The voltage gain at this time is determined by the following formula: GV = │R11+R9/ (│+j ωC9・R9)│/R3 Obtain the necessary gain by regulating the (power-on pop noise prevention) NAB time constant circuit in the same way when regulating the gain at recording stage. The operating point of the output stage (1,7pin) is fixed at 3VF. Accordingly, even if VCC is raised to 5V or more, as in the VMAX-VCC characteristic (Fig.13), the maximum output voltage does not rise above 1.2V (Typ.). 4pin is grounded at playback since ALC is not needed. For better signal-to-noise ratio characteristics at playback, don’t use R1 and R2, which are attached to the input pin (13pin, 9pin).
