The single channel voice processor format has become the accepted way of getting the most out of any sound source. The 5051 provides the perfect front end for any system by offering a combined preamp, compressor, equaliser and noise gate all in one easy-to-use package: now with an optional digital output. The 5051 compressor section is identical to that of the 5021 and includes hard/soft knee modes, and the four band equaliser section is modelled on that of the legendary TL Audio EQ-1 - yielding superb results instantly, with an improved optical gate for removing unwanted source noise. So whatever your source, let the 5051 unlock its true potential!

The 5051 features no less than six valve stages, supplied by three twin triode ECC83/12AX7A valves running from a stabilised 150V DC power supply. One valve stage is located in the preamp, one in the compressor gain control circuit, and four in the equaliser section.
