Mackie Onyx 24.4 – No Longer Available

24-channel/four-bus premium SR console
MFR# 0015900-00

Product Description

From Mackie, the Onyx 24.4 is a 24-channel, four bus live sound mixer for use in mid-size venues. Much like the preceding SR series mixers, the Onyx 24.4 is designed to deliver optimum, professional quality in a compact, portable frame. 24 input channels feature 1/4" phone line level connectors and Mackie's famed Onyx microphone preamplifiers.

The Onyx microphone preamps boast an impressive 123dB total dynamic range, -129.5 dBm Equivalent Input Noise (EIN) and 0.0007% Total Harmonic Distortion (THD) for an overall sound that rivals expensive "boutique" mic preamps. The Onyx four-bus mixers feature an internal compressor / limiter for complete control over dynamics, transients and level fluctuation.

Each channel features Mackie's patented four-band Perkins EQ for high quality "British" EQ style signal contouring. There is no shortage of routing options with its 6 x 2 matrix providing sufficient monitor sends, four-bus group outputs for routing channel signal to recorders and direct outputs on DB-25 connectors. The Onyx 4-bus live sound consoles are full featured, portable work-horse mixers for touring, small venue, house-of-worship, schools, halls and more.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
