Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Mic/Line Preamp Section: The 4-channel 402VLZ4 analog mixer features two of
Mackie's flagship Onyx mic preamps in an ultra-compact design that offers both
Mic & Line inputs. This preamp design is excellent at rejecting hum and noise.
- Mic Inputs (Ch. 1-2): The mixer's channel 1-2 mic inputs consist
of female XLR connectors. You can plug in almost any kind of mic that has a
standard XLR mal mic connector. Professional ribbon, dynamic, and condenser
mic will sound excellent through these inputs. The 402VLZ74's mic inputs
will handle any kin of mic level without overloading. Most modern professional condenser mic are equipped for phantom
power, which lets the mixer send low-current DC voltage to the mic's electronics
through the same wires that carry audio. Phantom power for both mic channels 1-2
is turned on and off together.
- Line Inputs (Ch. 1-2): The mixer's channel 1-2 line inputs
consist of female 1/4" phone connectors. These input share circuitry (but
not phantom power) with the mic preamps, and can be driven by balanced or
unbalance sources at almost any level. You can use these input for virtually
any audio signal. To connect balance lines to these inputs, us a 1/4" TRS
phone plug. to connect unbalanced lines to these inputs, use a 1/4" TS phone
plus. These two line inputs are a good place to connect older instruments
that need more gain.
Note: You can adjust the input sensitivity (Gain) of the Mic/Line
channel 1-2 inputs. You can also adjust the channel level of each Mic/Line
input to determine the level of the signal that is sent from each input
channel to the mixer's main output.
Stereo Line Inputs (Ch. 3-4): The mixer's channel 3-4 line inputs
consist of female 1/4" phone connectors. These fully-balance inputs are designed
for stereo or mono, balanced or unbalanced signals. They can be used with just
about any professional or semi-pro instrument, effect, or CD player. Signal
entering channel 3 are added to the left side of the main mix only, while
signals entering channel 4 are added to the right.
Main Outs: The mixer's main outputs consist of two 1/4" phone
connectors These outputs feed the main mix out to line-level inputs of your
power amplifier, powered speakers, or another mixer. Use a 1/4" TRS connector
cable for a balanced connection and a 1/4" TS connector for a non-balanced
connection. There is Main Mix level knob which control the level of signals sent
to the main outputs. All channels that are not turned fully down will wind up in
the main mix.
Tape Input/Tape Output: The 402VLZ4 offers both Tape inputs and Tape
- Tape In: These dual, unbalanced RCA inputs accept line-level
stereo signals. The signals entering these inputs are always routed to the
phones output, but can also be routed the main output. Use these jacks for
convenient playback of your mixes. You'll be able to review a mix and then
try another pass without repatching or disturbing the mixer levels. You can
also use these jacks with an iPod, computer, or CD player. There is Tape
Level knob which lets you adjust the level of the tape input playing in the
main mix and headphones.
- Tape Out: These unbalanced RCA connections tap main mix output to
make simultaneous recording and PA work more convenient. Connect these to
your recorder's inputs. This output is an unbalanced copy of the main mix
and it is affected by the main mix level.
Headphone Jack: This stereo 1/4" jack will drive any standard
headphone to very loud levels. In the headphones, you will hear the main mix as
well as any source playing the tape inputs. Adjusting the main mix level will
not affect the headphone output; adjusting the tape level will affect the level
of the tape input signal heard in the headphones. There is a Phones Level knob
which allows you to adjust the level of the signal going to your headphones.
2-Band EQ: The 402VLZ4 has 2-band equalization at carefully selected
points; low shelving at 80Hz and high shelving at 12kHz. "Shelving" means that
the circuitry boosts or cuts all frequencies past the specified frequency.
- High EQ: This control gives you up to 15dB boost or cut above
12kHz and it is also flat at the center.
- Low EQ: This control gives you up to 15dB boost or cut below
80Hz; the circuit is flat at the center position.
Meters: The 402VLZ4's peak metering system is made up of two column of
eight LEDs. It displays the signal level after the main mix level control.
Applications: The Mackie 402VLZ4 is great for live sound mixing,
houses of worship, clubs, gymnasiums, banquet halls, conference rooms
boardrooms, studio and field recording, multimedia applications, broadcast, and
many other applications.
