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. VR resistance : 20 k Ω VR resistance : 20 k Ω VR resistance : 20 k Ω 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. Pin Description ( ) : LC7537AN, 7537NE 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 k Ω. VR resistance : 20 k Ω VR resistance : 20 k Ω 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). |
