32-channel Premium Analog Mixer with 28 Onyx Preamps and 4-band Perkins EQ. Mackie's Onyx 32x4 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 32•4 while adding 100mm Panasonic faders, Onyx mic preamps, redesigned analog circuitry, Perkins EQ, and a built-in assignable stereo compressor/limiter section.
