Phantom Power
Most modern professional condenser mics require
48V phantom power, which lets the mixer send
low-current DC voltage to the mic’s electronics
through the same wires that carry audio. (Semi-pro
condenser mics often have batteries to accomplish
the same thing.) “Phantom” owes its name to an ability
to be “unseen” by dynamic mics (Shure SM57/SM58,
for instance), which don’t need external power and
aren’t affected by it anyway.
The ProFX mixer’s phantom power is
globally controlled by the phantom power
switch (meaning that phantom power for
all mic inputs is turned on and off together.)
Never plug single-ended (unbalanced)
micro phones or ribbon microphones into
the mic input jacks if phantom power is on.
Do not plug instrument outputs into the mic input jacks
with phantom power on unless you know for certain it
is safe to do so.
6. Line / Hi-Z Switch [ProFX8v2 / ProFX12v2]
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 channel 1's 1⁄4" TRS
input. The input impedance is optimized for direct
connection and high-frequency fidelity is assured.
In the out position, channel 1's 1⁄4" 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. Line Inputs
Hi-Z Input (Channel 1 Only) [ProFX8v2 / ProFX12v2]
In addition to accepting balanced mic or line-level
signals using an XLR connector, ProFXv2 Series mixers
may also accept 1/4" line-level signals driven by
balanced or unbalanced sources. These 1/4" jacks
share circuitry (but not phantom power) with the
mic preamps.
To connect balanced lines to these inputs, use
a 1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for
Tip-Ring-Sleeve, the three connection points available
on a stereo 1/4" or balanced phone jack or plug.
