Description
(d) Balance
The balance control function is valid only in balance display mode.
This function becomes valid as soon as either of these keys is pressed. Pressing a key increments
or decrements the balance by one step, respectively.
When the key is held down for about 0.5 seconds, the balance is successively incremented or
decremented at a rate of one step every 0.3 seconds. Incrementing or decrementing stops when
BAL CNT is reached.
The initial value when the power is first applied is BAL CNT (0 [dB]) for both the left and right.

(e) Fader
The fader can be adjusted when initial setting diode FAD = 0.
This function is valid in fader display mode.
This function becomes valid as soon as either of these keys is pressed, and the fader is
incremented or decremented by one step.
When the key is held down for about 0.5 seconds, the fader is successively incremented or
decremented at a rate of one step every 0.3 seconds. Incrementing or decrementing stops when
FAD CNT is reached.
The initial value when the power is first applied is FAD CNT (0 [dB]) for both the front and rear.
