Before Connecting

Before connecting other devices, connect the jack side of 
the accessory power cable to the AC inlet of this unit.

When connecting, turn off the power supply of this unit and 
the power supplies of auxiliary devices to prevent unex-
pected accidents that may be caused by noise.

How to connect power supply

Use the accessory power cable and insert the AC plug in 
the outlet on the wall in the room where the unit is installed.

How to connect CD player, control 
amplifier

Connect the output terminal of a control amplifier to the in-
put terminal with 2 (R and L) pin-plug cables.
When using a source device without the volume adjusting 
function, such as a CD player, connect to the VARIABLE 
input terminal. When using a source device with the volume 
control, such as a control amplifier, connect to the DIRECT 
input terminal.
Select DIRECT or VARIABLE input with the input selector.

How to connect speakers

Connect the right-channel speaker to the right speaker ter-
minals of the MQ-88uSE power amplifier and the left-chan-
nel speaker to the left speaker terminals.
Securely connect the 

!

 terminal of the speaker system to 

the speaker terminal 

!

 (red) of this unit, and the 

@

 terminal 

of the speaker system to the speaker terminal 

@

 (black) of 

this unit.
If the 

!

 and 

@

 terminal is reversely connected to either of 

the right or left of the speaker system, the signal phases 
reproduced from the right and left of the speaker system 
are also reversed. In such a case, be aware that the sound 
level in the low range will be reduced and the acoustic sta-
bility will worsen, thus the normal stereo playback is not 
achieved.
