Phantom power may be selected by engaging the mixer's phantom [35] switch.

Never plug single-ended (unbalanced) microphones,­ or ribbon mics into the mic

input jacks if phantom power is on. Do not plug instrument outputs into the mic XLR input jacks with phantom power on, ­unless you are certain it is safe to do so.

6. LINE INPUTS

These 1/4" jacks share circuitry (but not phantom power) with the mic preamps, and can be driven by balanced or unbalanced sources.

To connect balanced lines to these inputs, use a 1⁄4" Tip-Ring-Sleeve (TRS) plug, wired as follows:

RING SLEEVE SLEEVE RING TIP

SLEEVE

Tip = Positive (+ or hot) Ring = Negative (– or cold) Sleeve = Shield or ground

To connect unbalanced lines to these ­inputs, use a 1⁄4" mono (TS) phone plug, wired as follows:

Level control is available –20 dB to +20 dB. If you are connecting a mono source, use the left (mono) input, and the mono signals will appear on both sides of the main mix.

The first two stereo channels [9/10 and 11/12 on the ProFX16 and 15/16 and 17/18 on the ProFX22] are

Mono Channels	Stereo Channels
Channels 1-8 on ProFX16	Channels 9-16 on ProFX16
Channels 1-14 on ProFX22	Channels 15-22 on ProFX22

hybrid channels, each with a mic input XLR jack [5] and low cut switch [10]. In these channels, the gain control [9] only affects the mic input. The stereo line inputs are fixed at unity gain.
