The Violectric PPA V790 is a state-of-the-art phono preamplifier with surprising features.

It offers a huge variety of adjustments, easily accessible from the front panel, plus newly developed extremely low-noise and distortion-less amplifier technology. Because of its multiple inputs, up to six differing cartridges may be managed in only one amp, and individually treated in terms of impedance, capacity, gain and EQ.

Up to six cartridges (3 x balanced, 3 x unbalanced) may be connected to PPA V790 at the same time.

For each cartridge the input impedance, the input capacity, the EQ level, the subsonic filter and the output boost may be set individually. All this is achieved via clearly denoted push-buttons and displayed by white LEDs on the front panel. All settings are stored. The usual distinction between MM and MC cartridges in most phono preamps does not apply to the PPA V790.

Instead, beneath standard cartridges, MC High-Output, or MM Low Output can be treated individually by the wide and open gain adjustment, ranging from +30 to +66 dB.

The gain stages inside the Violectric PPA V790 are DC coupled with cascaded bipolar super-fast input transistors. This gives the highest bandwidth, extreme low noise, lowest distortions and highest dynamic range. Do not expect any coloration from this amplifier! Gain may be set in 7 steps from +30 dB (factor 30) to +66 db (factor 2000). A clip indication is displayed to avoid incorrect operation.

PPA V790 offers three DC coupled EQs. Beneath the usual RIAA filter, NAB and Columbia-LP EQs may be selected for more exotic recordings. The filter accuracy is 0.1 dB. A switchable subsonic filter also helps to eliminate low frequency interferences. The Boost circuitry with 0, +6 und +12 dB settings is intended to adapt Violectric PPA V790 into virtually any signal chain.
