FCircuit operation

(1) As shown is the block diagram, the main circuit

blocks are the main volume (front and rear), tone control

(bass and treble), and balance and fader. Signal control

for each block is possible with a DC voltage.

(2) The main volume is comprised of a front volume

and rear volume controller. The front volume controller

has 18dB of attenuation.

(3) ThetonefilterisanexternalCRcircuit. Refertoitem

5 of the application notes regarding the component val-

ues.

(4) The loudness is set by a calculation based on the

tone control current. Refer to control curves item 3 of the

application notes.

(5) The control curves for the balance and fader are

given in the measurement data.
