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 consoles
upgrade the performance and functionality of the legendary Mackie
SR24•4 and 24•4 while adding 100mm Panasonic faders, 20 Onyx mic
preamps, redesigned analog circuitry, Perkins EQ, and a built-in
assignable stereo compressor/limiter section.
20 Onyx Microphone Preamps
The Onyx 24x4 analog mixer is
loaded with Mackie's flagship Onyx mic preamps, offering excellent
fidelity, headroom, and transparency. With specs like 123dB total
dynamic range, -129.5 dBm Equivalent Input Noise, and 0.0007% Total
Harmonic Distortion, Onyx preamps hold their own against boutique
standalone mic pres. When you need crystal-clear fidelity, look no
further than the Mackie Onyx 24x4 mixer with its superb mic pres.
Redesigned Analog Circuitry
Mackie
spared no expense developing the Onyx 24x4 analog mixer, pulling
together some of the highest-quality components 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 input to output, offering big,
full-range sound and lower noise than many mixers in this class. Most
significantly, premium Onyx mic preamps, Perkins EQ circuitry, and a
THAT Corporation 4301 assignable stereo compressor/ limiter chip were
custom tailored specifically for these new consoles.
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 built on the
classic Wein Bridge circuit topology used in British consoles during
the '60s and '70s, but offers increased filter and phase shift control.
The end result is an extremely musical and very 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 built one into the circuitry of the Onyx 24x4 mixer. And not just
any compressor/limiter chip would do, so Mackie chose a high-quality
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
system limiting and protection) or pre-fader to Group 1 / 2 or 3 / 4
outputs (for grouped signal compression, like drums or background
vocals). This reduces the hassle 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 switchable via internal jumpers as either pre- or
post-EQ. These outputs are ideal for multi-track live recording.
