Benchmark PRE420 - Microphone Preamplifier / Mixer - Discontinued

The PRE420 has been discontinued. A remarkable four-channel microphone preamplifier with an integrated stereo mix bus and stereo/mono solo bus in a sleek, 1RU chassis. The PRE420is designed for maximum transparency, wide bandwidth, low-noise, low-distortion, and superior RF immunity. It is well suited for the most demanding applications in studios and live venues. What Makes a Microphone Pre-Amplifier Transparent? Even high-end preamplifiers can mask subtle details because of intermodulation distortion, a symptom of RF interference and non-linear performance at ultra-sonic frequencies. This non-linearity causes inter-modulation distortion (IMD) components that fold down to audible frequencies. Unlike harmonic distortion (THD), IMD produces distortion tones that are very un-natural and non-musical. 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
