Combi Jacks
Rear Panel inputs 1-4 feature a combination (combi) input connector that is able
to receive an XLR or 1/4” plug through the same jack� Set the input source via
Ensemble’s front panel controls (page 17), or from the Apogee Control software
(page 46) according to the input connector being used�
• When using the 1/4” input, the source must be set to “Inst”.
• When using the XLR input, the source may be “Mic”, “+4dBu”, or “-10dBV”.
When Input Source is set to:
Mic - The XLR input is sent to the microphone preamp circuit�
Inst - The 1/4” input is sent through a Hi-Z to Low-Z conversion circuit, then the microphone preamp circuit�
+4dBu - The XLR input bypasses the microphone preamp circuit and sent to the A/D converter�
-10dBV - The XLR input is converted to +4dBu, bypasses the microphone preamp, and sent to the A/D
converter�
