Circuit diagram
〈VCC
Power supply for anything other than REC + B.
〈REC MUTE CTRL〉
REC MUTE control.
In REC MUTE mode, the recording amplifier
output is stopped.
REC: L, REC MUTE: H.
Do not leave open circuit.
〈OVER REC CTRL〉
OVER REC control.
In OVER REC mode, the recording current is set
to + 2dB (Typ.).
Do not leave open circuit.
〈REC MIX IN〉
Recording amplifier input.
〈REC NF〉
Recording amplifier feedback.
Connect the GND of a decoupling capacitor to
main GND (pin 16) to improve common-mode
distortion.
〈REC / PB CTRL〉
REC / PB control pin.
Use of an RC circuit time constant to slow the rise
of the control signal reduces noise spikes during
switching.
Do not leave open circuit.
