Mackie Onyx 1640i User Manual

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 master L/R to be routed to any desired DAW, including Pro Tools® 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 ¼-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.
