Input signal specifications: Short-circuit current: 10 mA or less, open voltage: 35 V DC or less
7.7. Connecting the External Equipment between the Line Output and the Power Amplifier
Appropriate sound can be obtained by connecting a signal processor like an equalizer or limiter between the
unit's preamplifier section (Line output jack) and the power amplifier section (Power amplifier input jack).
Notes
• When using the signal processor, be sure to turn OFF the unit's line output interlock switch.
• Inserting a pin plug into the unit's power amplifier input jack disconnects the preamplifier section from the
power amplifier section inside the unit.
Tip
Either Line output 1 or 2 can be used.
