Introduction
Mackie’s 1402-VLZ PRO combines the compact
size of the 1202-VLZ PRO with added features and
60mm log-taper faders. Its six new “audiophile”
XDR™ Extended Dynamic Range mic preamps offer
the best RFI rejection of any compact mixer design.
Added benefits include maximum freedom from
ground loops and impeccable sonic performance
that meets or exceeds the specs of esoteric, outboard mic preamplifiers. The XDR design is the only
compact mixer mic preamp that is totally impedance
independent: frequency response does not change
even with extremely long cable runs or exceptionally
high-impedance mic inputs.
A sharp, 18dB/octave 75Hz Low Cut filter on each
mic channel greatly reduces mic thumps, wind noise
and stage rumble. Mute/Alt 3-4 effectively creates a
second stereo bus. The Mute button on each channel
mutes that channel in the Main Mix, while simultaneously placing the signal on the Alt 3-4 stereo bus,
greatly increasing signal routing flexibility.
The EFX to Monitor feature allows routing of
reverb or other effects signals back into a monitor
mix via Aux Send 1. Aux 1 Master’s Pre/Post switch
can be set for pre-fader/post-EQ use, which is beneficial for stage monitor mixes, or post-fader/post-EQ
for use with external effects. It also has a level control for added flexibility.
Control Room/Phones has its own level control,
stereo output pair and input matrix for selecting any
combination of Main Mix, Tape In and Alt 3-4 to
create custom headphone mixes, to monitor tape
levels, and more. A separate switch routes this
multi-source signal back into the Main Mix.
Because of its many features and durability, the
1402-VLZ PRO can be used for extra studio-grade
preamps, as aux inputs for a mixing console, or as
an impedance- or level-matching audio toolkit.
