Radial Workhorse Powerpre 500 Mic Preamp

Description

The PowerPre is designed for clean low-noise operation, with an AccuState input stage what automatically optimises signal-to-noise at all levels with up to 55dB of gain available. A Hammond broadcast transformer on the output provides vintage warmth and a classic smooth tone, and a Vox switch allows you to add extra character to the signal: The Breath setting adds high frequency air that can accentuate a vocal track or add harmonic content to an acoustic guitar, while the Punch setting adds body when recording electric guitar or it can be used to fatten up bass tracks. =+= Technical Specification
