MACKIE PROFESSIONAL MIC/LINE MIXERS WITH FX AND USB I/O PROFX16 - Manual (Page 12)

12 ProFX16 and ProFX22
Phantom power may be selected by engaging the
mixer's phantom [35] switch.
Never plug single-ended (unbalanced)
micro phones, 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:
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:
Tip = Positive (+ or hot)
Sleeve = Shield or ground
7. STEREO LINE INPUTS
The stereo line inputs are designed for 1/4" TRS
balanced or 1/4" TS unbalanced signals. They may
accept any line-level instrument, effects device, CD
player, etc.
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
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.
