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.
