• Fader outputs. The front and rear systems can be attenuated independently.

• 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.

• Super bass compensation capacitors

• 4-dB volume control inputs

• These inputs must be driven from low-impedance circuits.
