Mackie 1642-VLZ Pro Parts list
Introduction
The 1642-VLZ PRO is perfect for applications where
more line-level inputs (and fewer mic preamps) are
needed.
Channels 1–8 are essentially the same as our
1604-VLZ PRO with mono line-level input and our
new ultra-high-quality XDR™ (Extended Dynamic
Range) mic preamps with the best RFI rejection of
any compact mixer design on the market and maximum freedom from ground loops.
Channels 9/10 and 11/12 (two physical channel strips) each have a stereo pair of line-level
inputs and a mono XDR™ mic preamp.
Channels 13/14 and 15/16 (also in two physical channel strips) each have a stereo pair of
line-level inputs only with xed four-band equalization at points that are especially benecial to
line-level inputs such as keyboards.
Like all of Mackie Designs’ mixers, the 1642-VLZ
PRO is designed for rugged, 24-hour-a-day use. It is
a supremely exible mixer, not just because of its
multiple input/output congurations, but because
of its true 4-bus architecture, 4 aux sends, and
extensive routing capabilities.
Built like a tank, the 1642-VLZ PRO is a team player
that can stand up to vigorous use, day in and day out, any
place it is installed. Its sturdy-yet-light steel monocoque
construction houses rugged, double-sided through-holeplated berglass circuit boards, and 60mm faders with
ultra-tight lip seals for keeping out dust and other contaminants. Impact-resistant knobs are mounted so they
“ride” just above the steel chassis—they absorb impact
without trouble. They’re designed to last, too, thanks to
co-molded potentiometers that don’t get brittle and crack
up. Then we use metal stand-offs at regular intervals to
mount thick berglass circuit boards inside the mixer.

Radio frequency interference from TV/radio stations and cellular phone users is virtually eliminated,
thanks to Mackie’s new XDR mic preamp design.
The mixer’s built-in power supply is beefy enough
to handle major power consumption without breaking
up. And there’s no bulky “wall wart” to be kicked out
of place or to cover up extra outlets.
All of this adds up to an extremely durable mixer
that can withstand major use. Multi-user venues such
as churches, night clubs, A/V rooms and schools are
perfect homes for the 1642-VLZ PRO.
Ten XDR mic preamps deliver the nest quality
sound ever offered in a compact mixer. They cannot
be damaged by hot patching. And they are imped-
