A pin for outputting the BBE
ΙΙ
signal.
Connect the LPF capacitor
between the MIX1 and MIX2 pins
and connect this pin to a rear stage
circuit through a coupling capacitor
between the TIN1 and TIN2 pins.
A pin for inputting a sound signal
to Treble.
The input impedance is 47k
(upon typical setting).
Connect this pin to a front circuit
through a coupling capacitor
between the BBOUT1 and BBOUT2
pins.
A pin for time constant of high pass
boost detector of BBE
ΙΙ
.
Attack/Recovery time depends on
the external capacitor and resistance.
T=CR (sec)
A pin for ON/OFF switching time
constant of BBE
ΙΙ
.
Timing constant "T" depends on the
external capacitor "C" and internal
resistance "R" (upon typical setting).
