Step 1. Loosen the screw.
Step 2. Shift the impedance selector switch to "DIRECT 4 Ω" position.
Step 3. Retighten the screw.
6.3.1. Mute control connection
The Mute control works to mute only the modules having mute function.
Short-circuiting between MUTE 1 and GND terminals mutes the modules set for "mute receive" function
activated on the MUTE 1 bus. Likewise, short-circuiting between MUTE 2 and GND terminals mutes such
modules on the MUTE 2 bus.
In this case, the modules set for "mute send" function are not muted, having precedence over "mute receive"
modules. For details, refer to the module's instruction manual.
6.3.2. Remote volume control connection
The connected potentiometer serves as the remote control of the Master volume control on the unit's front
panel.
Note: The controllable maximum volume is limited up to the volume set with the Master volume control. So,
do not place the Master volume control in the counterclockwise position when using the remote volume
control.
This type of output allows speaker connection to 4 Ω terminal only.
