ADJUSTING INPUT VOLUME

Power Amplifier
(WA-MA120N, MA240N, etc.)
for High-Impedance Loudspeakers
Pre-amplifier, etc
Line-level equipment, etc.
• When line-level equipment is connected to LINE IN, use the LEVEL knob on the back of the Amplifier to adjust the volume to
the desired level.
• Input volume cannot be adjusted when power amplifier output is connected to 100 V.
Adjust the output level of the power amplifier in this case.
Note:
• When LINE IN and 100 V are connected to different audio signal sources at the same time, the inputs are mixed.
