ProFXv3 Professional Effects Mixer with USB
ProFXv3 Professional Effects Mixer with USB
10
To connect balanced lines to these inputs,
use a /4" Tip-Ring-Sleeve (TRS) plug. To connect
unbalanced lines to these inputs, use a /4" mono (TS)
phone plug. Wiring diagrams for both connectors
are presented on page 8.
NEVER connect the output of an amplifier
directly to a ProFXv3’s input jack. This could
damage the input circuitry and we wouldn’t
want that now, would we?
6. Line / Hi-Z Switch [Chs.  and 2]
To connect a guitar directly to the mixer without
using a DI Box, press this switch in first; then connect
the output from the guitar to the channel’s /4" TRS
input. The input impedance is optimized for direct
connection and high-frequency fidelity is assured.
In the out position, the channel’s /4" TRS input
becomes a line input just like the other mono line
inputs.
To use guitars or other instruments on other
channels, you will need to use an external DI box first.
Without the DI box – or if this switch is not pressed
in – guitars may sound dull and muddy.
7. Mic Ins
This is a female XLR connector that accepts a
balanced mic or line level input from almost any type
of source. These Onyx mic preamps feature higher
fidelity and headroom rivaling any standalone mic
preamp on the market today. These circuits are
excellent at rejecting hum and noise.
Professional ribbon, dynamic, and condenser
mics all sound excellent through these inputs.
The mic / line inputs will handle any kind of level
you can toss at them, without overloading.
Wiring diagrams for these XLR connectors
are presented on the previous page.
NEVER connect the output of an amplifier
directly to a ProFXv3’s input jack. This could
damage the input circuitry and we wouldn’t
want that now, would we?
8. Line Ins
These /4" jacks share circuitry (but not phantom
power) with the mic preamps, and can be driven by
balanced or unbalanced sources at almost any level.
You can use these inputs for virtually any signal you’ll
come across.
To connect balanced lines to these inputs, use a /4"
Tip-Ring-Sleeve (TRS) plug. To connect unbalanced
lines to these inputs, use a /4" mono (TS) phone plug.
Wiring diagrams for both connectors are presented on
page 8.

9. Stereo Line Inputs
The stereo line inputs are designed for /4" TRS
balanced or /4" TS unbalanced signals. They may
accept any line-level instrument, eects device, CD
player, etc.
If you are connecting a mono source, use the lef
(mono) input, and the mono signals will appear
on both sides of the main mix.
To connect balanced lines to these inputs, use a /4"
Tip-Ring-Sleeve (TRS) plug. To connect unbalanced
lines to these inputs, use a /4" mono (TS) phone plug.
Wiring diagrams for both connectors are presented on
page 8.
NEVER connect the output of an amplifier
directly to a ProFXv3’s input jack. This could

0. /8" Stereo Input
This stereo input may accept an /8" line-level signal
from a phone, MP3 player, or other signal source.
Last one! NEVER connect the output of an
amplifier directly to a ProFXv3’s input jack.
This could damage the input circuitry and
we wouldn’t want that now, would we?
