5. AUDIO OUT & RCA JACK CONNECTION
Use the RCA connection on the back of the unit to connect the unit to your PBX or Key
phone system. Most PBX and Key systems will be equipped to accept an RCA jack
connection. Some systems may require a 3.5mm mini connection.
Cables for both RCA-to-RCA and RCA-to-3.5mm are included with the GDI-USBM10.
6. IMPEDENCE SWITCH
The impedance Switch on the back of the unit has selections for 8 ohm and 600 ohm
output setting. 8 ohm is the default for most PBX and Key Phone systems. IP based
phone systems may require a 600 ohm setting.
7. TRIGGER JACK
The 2.5mm Trigger Jack connection on the back of the unit is designed for use with a
momentary switch enabled device. When the jack is activated by the momentary switch,
audio should start from the beginning of the program.
8. POWER ADAPTER CONNECTION
Power to the unit is provided by a wired power connection. Connect the pronged end of
the 5V power adapter to a power outlet and connect the other end to the power adapter
connection on the back of the unit. Once connected, turn the power ON by pressing the
Power Button on the front of the unit.
