The Radial PowerPre is a 500 series 100% discrete mic preamp with Accustate input control for low noise and transformer coupled output for added warmth.
The Radial PowerPre? is a high performance microphone preamplifier designed to be used with the Radial Workhorse and other 500 series modular racks. It features 100% discrete components for optimal signal transfer and employs a 'vintage' Hammond broadcast output transformer for warmth and exceptionally smooth tone.
The design begins with a front mounted XLR for instant connectivity plus a recessed 48V phantom power switch for safety. Unlike most mic preamps that require careful gain adjustment to avoid troublesome noise, the PowerPre is equipped with the newly developed AccuState? input stage that automatically optimizes signal-to-noise at all levels with up to 55dB of gain. This is supported with a full 10 segment LED meter for precise signal monitoring.
To add extra character; a 3-position Vox control lets you set the PowerPre to 'breath' for added high frequency air such as when accentuating a vocal track or adding harmonic content to an acoustic guitar. The 'punch' setting adds body when recording electric guitar or can be used to fatten a voice. When set to linear, the PowerPre delivers a truly natural rendering for orchestral recording that will suit the most demanding purist. This is augmented with a gentle high-pass filter that helps control low end resonance when layering acoustic instruments.
Ultra quiet, low noise and exceptionally warm sounding... the PowerPre makes spectacular audio easy.
