The PPA Violectric PPA V790 is a state-of-the-art phono preamplifier with absolute unsuspected features until now. It offers a huge variety of adjustments, easily accessible from the front panel and a 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.PPA V790 offers:
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 law, the subsonic filter and the output boost may be set individually. All this is done by clear 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 such amps was renounced.
Instead, beneath “standard” cartridges also “MC High-Output” or “MM Low Output” can be treated individually by the wide and open gain adjustment from +30 to +66 dB.
The gain stages inside Violectric PPA V790 are DC coupled with cascaded bi-polar superfast input transistors for highest bandwidth, extreme low noise, lowest distortions and highest dynamic range. Don´t expect any coloration from this amp! Gain may be set in 7 steps from +30 dB (factor 30) to +66 db (factor 2000). A clip indication is in charge 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 “exotic“ recordings. The filter accuracy is 0,1 dB.
A switchable subsonic filter 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.
