The Series 80B Dual Microphone Preamplifer and Equalizer from Trident Audio is a 2-channel, rack-mountable version of the Series 80B console. Comprising two independent channels, each with a microphone/line amplifier and four-band equalizer, it is designed to process incoming signals from a microphone or line-level instrument and output to a recording device such as a digital audio workstation or analog multi-track tape recorder.
In keeping with the functionality of the Trident Series 80B console, each channel strip of this rack unit features insert points, phase reverse (which operates on both microphone and line inputs), and an output level control with peak signal indication. All inputs and outputs are balanced so that maximum signal integrity and high output levels are assured with minimum distortion.
The Series 80B rack incorporates a classic 4-band equalizer, which is identical to that employed in the Trident Series 80B console. It consists of frequency-switchable, high- and low-pass shelving sections, coupled with two swept low and high mid-range bands and a switchable 50 Hz, 12 dB per octave filter.
