About external power amplifiers
We recommend using power amplifiers that meet the following conditions.
- With unbalanced inputs
- With volume control bypass (or without volume control circuit)
- Output power: 100 W (8Ω) or more
• When using an external amplifier that does no have the volume control bypass, turn up the volume of the
external amplifier enough and fix it.
Caution
• To prevent the generation of loud noises or abnormal sounds, make sure the followings before making
connections.
- Remove the power cable of this unit and turn off the external power amplifier before connecting them.
- When using the PRE OUT jacks, do not connect speakers to the corresponding SPEAKERS
terminals.
- When using an external amplifier that does not have the volume control bypass, do not connect other
devices (except this unit) to the amplifier.
