The Mackie ONYX 1640 16-Channel Mixer is a premium 16-channel, 4-bus small-format analog mixer. It features all-new circuitry including 16 boutique-class Onyx mic preamps with 4-band Perkins EQ plus sweepable mids on mic/line channels. Other features include six aux sends with pre/post switches, four stereo line-level inputs, a built-in talkback section for use with internal or external mic, true hardware EQ bypass, and a "Planet-Earth" switching power supply for worldwide use. It's also equipped with individual 48V phantom power switches on all mic inputs, 60mm logarithmic taper faders for smooth, linear fades; balanced direct outs for every channel via DB-25 connections; and selectable instrument inputs on the first two channels, meaning no DI boxes are needed.
