6. LINE INPUTS

(MONO)
These 1/4" jacks share circuitry (but not phantom
R
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"

7. STEREO LINE INPUTS

XX / XX
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
1-2
player, etc.
3-4
Level control is available –20 dB to +20 dB. If you are
connecting a mono source, use the left (mono) input,
L-R
and the mono signals will appear on both sides of the
PFL
main mix.
SOLO
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.
Never plug single-ended (unbalanced)
micro phones, or ribbon mics into the mic
input jacks if phantom power is on. Do not
