Note
It is highly recommended that the low-cut switch be placed
in the CUT position to cut off unnecessary low frequency.
This is because the built-in transformer cannot produce low
frequencies though the unit has flat response even in low-
frequency range.
• When connecting speakers to the 4 Ω output (UNBALANCED DIRECT OUTPUT), connect as
illustrated below.

Step 8. Install modules.
Six input ports for plug-in modules are provided. Select the desired modules depending on
applications. Plug the modules fully into the input ports by sliding them along the upper and lower
guide rails, then secure each with two screws.
Be sure to cover idle slots with the blank panels attached to the unit and secure each with two screws.
Important
Be sure to switch off the unit’s power when
inserting or removing the modules. Failure to
do so may cause modules to fail.
Step 9. Attach the front cover.
To complete installation, be sure to attach the front cover onto the installed amplifier with the supplied
4 screws (screw thread by inch system).
Be sure to attach the front cover after connection completion.
Because high voltage is generated at the speaker output
terminals, never touch these terminals to avoid electric shock.
