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: 20KΩ 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: 100Ω 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.
