Fig.4
Volume control curve; voltage gain (Gv) as
a function of control voltage (V1-18).
Measured in Fig.1 (internal potentiometer
supply from pin 17 used); VP = 8.5 V;
f = 1 kHz.
Fig.5
Balance control curve; voltage gain (Gv) as
a function of control voltage (V16-18).
Measured in Fig.1 (internal potentiometer
supply from pin 17 used); VP = 8.5 V.
Fig.6
Bass control curve; voltage gain (Gv) as a
function of control voltage (V9-18).
Measured in Fig.1 with single-pole filter
(internal potentiometer supply from pin 17
used); VP = 8.5 V; f = 40 Hz.
