Connecting Peripheral Devices
Make connections as shown in the diagram below. When making any connections, make sure that all devices are turned off.
fig.00-301
To prevent malfunction and/or damage to speakers or other 
devices, always turn down the volume, and turn off the 
power on all devices before making any connections.
● To prevent the inadvertent disruption of power to your 
unit (should the plug be pulled out accidentally), and to 
avoid applying undue stress to the AC adaptor jack, 
anchor the power cord using the cord hook, as shown in 
the illustration.

● Feedback could be produced depending on the location 
of microphones relative to speakers. This can be 
remedied by:
1.  Changing the orientation of the microphone(s).
2.  Relocating microphone(s) at a greater distance from 
speakers.
3.  Lower the volume.
* Two types of MIC inputs are included, TRS phone type jacks 
compatible with balanced input, and XLR type connectors. 
The pin assignment for the MIC jack is as shown below. Before 
making any connections, make sure that this pin assignment is 
compatible with that of all your other devices.
