Description of Functions
Main volume control block 5 dB-step attenuator input terminals. These pins should be
driven at a low impedance.
Main volume control block 5 dB-step attenuator output terminals. Having been designed
to be open, the step positions will develop errors if at low acceptor impedances, so that as
high load impedances as possible should be provided.
Main volume control block 1 dB-step attenuator input terminals. Theses pins should be
driven at alow impedance.
Main volume control block 1 dB-step attenuator output terminals. Due to the step
positions designed to be open, load impedances as high as possible should be provided to
them, similar to those for the LC1 and RC1.
Fader functions employing mode input terminals. These pins should be driven at a low
impedance.
Fader block output terminals. These pins permit the front and rear sides to be faded out
independently of each other. Attenuations exercised on Lch will be the same as on Rch.
Due to the step positions designed to be open, acceptor impedances as high as possible
should be provided to them.
Bass tone control block terminals. A total of 15 positions have been provided in 2 dB
steps
Treble tone control block terminals. A total of 15 positions have been provided in 2 dB
steps. The VR resistance value is 20 kΩ.
Loudness dedicated terminals. A high-frequency-range correcting C should be put
between CT1 and IN, and low-frequency-range correcting C between CT2 and L–VSS
(R–VSS).
