A capacitor must be connected between Vref and VSS to suppress power supply ripple. • Fader outputs. The front and rear systems can be attenuated independently. The amount of attenuation is the same in the left and right channels. • Low impedance operational amplifier outputs • Fader inputs • Must be driven from low-impedance circuits. Tone control outputs Connections for the bass and treble compensation capacitors for the tone control circuit Connect high-band compensation capacitors between T1 and T2. Connect low-band compensation capacitors between T2 and T3. Loudness pins. Connect high-band compensation capacitors between LCT1/RCT1 and L10dBIN/R10dBIN, and connect low-band compensation capacitors between LCT2/RCT2 and LVref/RVref. Continued on next page. |
