Primo-sounding Mixer, Rock-solid Too!

Mackie's Onyx 24x4 analog live mixer offers nightclubs, bands, and houses of worship a console that doesn't force them to sacrifice channel count or sound quality when looking for a mid-sized analog console. Mackie's flagship Onyx 4-Bus Series live sound mixers upgrade the performance and functionality of the mythical Mackie SR24•4 and 24•4 while adding 100mm Panasonic faders, 20 Onyx microphone preamps, redesigned analog circuitry, Perkins EQ, and a built-in assignable stereo compressor/limiter section.

Mackie Onyx 24x4 Analog Live Mixer at a Glance:

• 20 Onyx microphone preamps
  
• Redesigned Analog Circuitry
  
• Built-in stereo compressor/limiter
• 4-band Perkins EQ
  

20 Onyx Microphone Preamps
The Onyx 24x4 analog mixer is loaded with Mackie's flagship Onyx microphone preamps, offering excellent fidelity, headroom, and transparency. With specs like 123dB total dynamic range, -129.5 dBm Equivalent In Noise, and 0.0007% Total Harmonic Distortion, Onyx preamps hold their own against boutique standalone microphone pres. When you need crystal-clear fidelity, look no further than the Mackie Onyx 24x4 mixer with its superb microphone pres.

Redesigned Analog Circuitry
Mackie spared no expense developing the Onyx 24x4 analog mixer, pulling together some of the highest-quality parts available-from premium op-amps to IC chips costing exponentially more than those used in previous designs. All-new summing bus circuitry was designed from the ground up to maximize the Onyx 24x4's headroom. And the entire signal chain was electronically balanced from in to output, offering big, full-range sound and lower noise than many mixers in this class. Most significantly, premium Onyx microphone preamps, Perkins EQ circuitry, and a THAT Corporation 4301 assignable stereo compressor/ limiter chip were custom tailored specifically for these new mixers.

4-band Perkins EQ
Mackie enlisted the aid of veteran audio engineer Cal Perkins to design the EQ circuit for the Onyx 24x4 live console. The Perkins EQ is made on the classic Wein Bridge circuit topology used in British mixers during the '60s and '70s, but offers increased filter and phase shift control. The end result is an extremely musical and totally effective 4-band EQ with sweepable low- and high-mids, making the Onyx 24x4 a perfect for mixing live sound.

Built-in Stereo Compressor/Limiter
Compression and limiting have been a live sound tool for years, so Mackie decided to made one into the circuitry of the Onyx 24x4 mixer. And not just any compressor/limiter chip would do, so Mackie chose a excellent master compressor/limiter chip from THAT Corporation for the Onyx 24x4. This assignable analog stereo compressor/limiter chip was designed and manufactured in the US by veteran analog engineers, offering true RMS Detection and Auto Make-up Gain for extremely accurate and musical results. It features independent Threshold, Ratio and Fast/Slow Attack controls, and can be assigned post-fader to the L/R main mix (for rig limiting and protection) or pre-fader to Group 1 / 2 or 3 / 4 outs (for grouped signal compression, like drums or background vocals). This reduces the pain and expense of separate outboard processing.

On the rear of each Onyx console are DB-25 female connectors (in groups of eight), which can be used to route all mic/line signals to an external device. These connectors are configured with standard TASCAM pin outs. All of these balanced direct outputs are pre-fader and selectable via internal jumpers as either pre- or post-EQ. These outputs are ideal for multi-track live recording.
