Other Inputs and Outputs
Common Input
A stereo input is provided for feeding a common signal to all of the 12 mix buses simultane-
ously. From the stereo source, the left signal will feed all of the odd mixes, the right signal will
feed all of the even mixes. Both XLR and 1/4” TRS jacks are provided, the XLR jack is normal'd
thru the TRS jack, so if a plug is inserted into the TRS jack, the XLR is disconnected.
Electronically balanced input: 20K
Ω impedance
XLR: Pin-2= Hot, Pin-3= Cold, Pin-1= Chassis
XLR is normal'd to TRS jack (see diagram):
TRS: Tip= Hot, Ring= Cold, Sleeve= Chassis
Nominal input level is +4dBu
Monitor Output
This output follows the Solo system and is controlled by both the HP/Mntr pot and SPEAKER
ON switch on the front panel.The pot controls the audio level of both the front panel
PHONES jack, and also these rear panel Monitor Out jacks.The SPEAKER ON switch enables
these rear jacks while leaving the PHONES unaffected.These jacks normally would feed the
engineer’s monitor system if something more than headphone listening was desired. Both TRS
and XLR jacks are provided, they are wired in parallel, and both sets may be used
Electronic balanced cross-coupled output: 100
Ω impedance (50Ω per leg)
XLR: Pin-2= Hot, Pin-3= Cold, Pin-1= Chassis
TRS: Tip= Hot, Ring= Cold, Sleeve= Chassis
Nominal output level is +4dBu.
