The Radial PowerPre microphone preamplifier fits inside a standard API style lunchbox frame. Its differential design and discreet components deliver up to 60dB of gain with low noise. The simplicity of the design is reminiscent of vintage equipment, and it avoids zero-cross distortion and other limitations imposed by off-the-shelf op-amps.
The Radial PowerPre also has a front-panel mounted XLR input for easy access with desktop workstations and a second XLR input via the lunchbox frame for traditional patch-bay setups. Phantom power is accessed via a protective set-and-forget recessed switch. This avoids erroneous activation, which could harm older vintage ribbon mics.
Other features include a ground lift for the XLR output and 180º polarity reverse. This is augmented with transformer isolation to eliminate hum and buzz caused by ground loops and a 10 segment LED for optimum signal monitoring.
When used with the Radial Workhorse, several new features are made possible. Both ¼-inch line level inputs and outputs are provided, and the Omniport has been designated as a high-impedance instrument input for direct-to-workstation recording. This is configured with a switching jack that will automatically disconnect the XLR inputs when it is being used.
