Description
An outstanding aspect lies in the ability to connect up to six pickups simultaneously, comprising three symmetrical and three asymmetrical configurations. Each pickup’s unique parameters—input impedance, capacitance, amplification, equalization, subsonic, and output adjustment—are stored individually and displayed prominently through white LEDs on the front panel, navigated through an intuitive button interface. The distinction between MM and MC systems is transcended by the broad gain settings, accommodating both MC high-output and low-noise MM systems, covering an extensive range from +30 to +66 dB.
Employing a DC-coupled amplifier featuring cascaded bipolar and super-fast input transistors, the Violectric PPA V790 guarantees maximum bandwidth, minimal noise, imperceptible distortion, and unparalleled dynamics. The amplification range spans from +30 dB (30x) to +66 dB (2000x), facilitated by a clip indicator to ensure accurate configuration.
Furthermore, the three DC-coupled equalizers—crafted to precision with a deviation of merely 0.1 dB—conform to standards such as RIAA, NAB, and LP- Columbia, catering even to unconventional sound mediums. Enhanced by a switchable subsonic filter to address low-frequency interference, the Violectric PPA V790 achieves harmonious integration with downstream systems through boost settings of 0, +6, and +12 dB.
