Onyx 1640i
Featuring a full 16 mono mic/line channels each with 4-band
dual sweep Perkins EQ, six aux sends each with pre/post
and solo capability, four subgroups and a powerful master
section, the Onyx 1640i is the flagship mixer of the Onyx-i
series.
The Onyx 1640i is equipped with 16x16 FireWire capability,
allowing all channels, aux sends, sub groups and main L/R
to be routed to any desired DAW, including Pro Tools®9 and
M-Powered™8. 16 channels of FireWire output from the
computer may be brought back directly into the channel
strips for a true tape-style mixdown. FireWire aggregation
allows multiple Onyx 1640i mixers to be connected.
Each channel has an Onyx mic preamp, phantom power, an
input Gain control with 60 dB of gain, a sharp 18 dB/octave,
75 Hz Low Cut filter, an EQ in/out switch, Pan, Mute, Solo,
assign switches, a 60mm fader and a Channel Insert jack
for connecting an external processor. In addition, two DB-25
connectors provide balanced direct outputs for channels 1-8
and 9-16, respectively.
There are built-in DIs on the first two channels for direct
connection of guitars or bass and a dedicated talkback
section for easy communication with band members on
stage or during recording sessions.
Other features include a stereo tape input and output, a
1/4-inch stereo headphone jack, stereo 12-segment LED
meters, BNC lamp socket and XLR and TRS stereo output
jacks.
The Control Room/Phones section has its own level control,
outputs and input matrix for selecting any combination of
Main Mix, Tape In and Subs.
Despite its large channel count, the Onyx 1640i is
compact, rack mountable and features our renowned
flexible RotoPod™design, allowing the mixer to be housed
in any configuration – from custom studio furniture, live
sound installs to post-production machine rooms. Plus, it’s a
Mackie which means it is “Built-Like-A-Tank” and will survive
years of abuse.
APPLICATIONS
Live sound mixing, houses of worship, clubs, gymnasiums,
banquet halls, conference rooms, boardrooms, multitrack
studio and field recording, video post-production,
multimedia applications, broadcast, and many, many more.
