Low Cut; Trim - Mackie 1202 VLZ Owner's Manual

To connect balanced lines to these inputs,
use a 1 ⁄ " Tip-Ring-Sleeve (TRS) plug, the type

found on stereo headphones:

Tip = Positive (+ or hot)
Ring = Negative (– or cold)
Sleeve = Shield or ground
To connect unbalanced lines to these
inputs, use a 1 ⁄ " mono (TS) phone plug or

standard instrument cable:

LINE IN inputs 1–4 are a good place to con-
nect older instruments that need more gain.
You can correct weak levels by adjusting the
corresponding channel's TRIM control .
LOW CUT (Channels 1–4)
The LOW CUT switch, often referred to as a
High Pass Filter (all depends on how you look
at it), cuts bass frequencies below 75Hz at a
rate of 18dB per octave.
We recommend that you use LOW CUT on
every microphone application except kick
drum, bass guitar, bassy synth patches, or
recordings of earthquakes. These aside, there
isn't much down there that you want to hear,
and filtering it out makes the low stuff you do
want much more crisp and tasty. Not only that,
but LOW CUT can help reduce the possibility
of feedback in live situations and it helps to
conserve the amplifier power.

you are inserting a signal that is very hot, or
when you want to add a lot of EQ gain, or both.
Without this "virtual pad," a scenario like that
might lead to channel clipping.
