Benchmark PRE420 Mic-Pre/Mixer Rack Mount Silver
The 4-channel Benbchmark PRE420 Mic-Pre/Mixer gives you a remarkable microphone preamplifier with an integrated stereo mix bus and stereo/mono solo bus in a sleek 1RU chassis. The PRE420 is designed for maximum transparency, wide bandwidth, low-noise, low-distortion, and superior RF immunity. It is well suited for the most demanding pro audio applications in studios and live venues.What makes one mic pre superior to others? Even high-end preamplifiers can mask subtle details because of intermodulation distortion, a symptom of RF interference and nonlinear performance at ultrasonic frequencies. This non-linearity causes intermodulation distortion (IMD) components that fold down to audible frequencies. Unlike harmonic distortion (THD), IMD produces distortion tones that are very unnatural and nonmusical. IMD also masks and alters the subtle details of delicate high-frequency transients such as those produced by bells. Benchmark MPS series preamps have always had outstanding high-frequency performance as well as freedom from IMD. The PRE420 takes the Benchmark design one step further, and achieves the lowest IMD that we have ever measured in any microphone preamplifier – the innovative circuitry provides ultra-low distortion over a 500kHz bandwidth while maintaining RF-immunity in the most demanding environments. Benchmark equips the PRE420 with the exclusive CMF1 RF-filter The CMF1 has been extensively tested and proven in Benchmark's MPS mic-pre series by experienced studio and remote recording engineers in heavy RF fields – such as venues in close proximity to broadcast antennas. This RF-immunity is coupled with ultra-low distortion performance at high frequencies beyond the reach of most mic pres, giving your audio remarkable realism. With amazingly low THD+N of 0.00024% (see specs), we welcome you to compare the PRE420's performance specifications with any other mic pre available. MirrorPan minimizes distortion & ensures constant-power precision panning MirrorPan's innovative mirrored-circuitry, from which the name is derived, eliminates the nonlinear distortion caused by potentiometer wiper-current. The result is excellent channel separation and remarkably accurate imaging. The center detent position is factory calibrated for precise center-placement. Elegant & completely unique feature set An elegant and completely unique feature set compliments the uncompromising sonic integrity of the PRE420.A solo section allows monitoring of any channel or combination of channels (with switchable stereo/mono) via control room XLR outputs and the integrated HPA2 – Benchmark's signature high-current, 0-Ohm headphone amplifier. The PRE420's main mix bus XLR outputs are monitored via a dual, variable intensity signal level meter and peak-warning indicator*. Each of the four channels has an independent direct XLR output, a variable intensity signal level meter and peak-warning indicator*, and MirrorPan control. Eac...details
