![]() The Boost circuitry with 0, +6 und +12 dB settings is intended to adapt Violectric PPA V790 into virtually any signal chain. The filter accuracy is 0,1 dB.Ī switchable subsonic filter helps to eliminate low frequency interferences. Beneath the usual RIAA filter, NAB and Columbia-LP EQs may be selected for “exotic“ recordings. A clip indication is in charge to avoid incorrect operation. 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). 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. 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. All settings are stored! The usual distinction between MM- and MC-cartridges in such amps was renounced. All this is done by clear denoted push buttons and displayed by white LEDs on the front panel. Up to six cartridges (3 x balanced, 3 x unbalanced) may be connected to PPA V790 at the same time.įor each cartridge the input impedance, the input capacity, the EQ law, the subsonic filter and the output boost may be set individually. Obviously all individual adjustments are stored.triple boost circuitry to perfectly adapt the amp into existing equipment.Clip indication to visualize incorrect operation.8 selectable capacities from 22 to 1000 pF (for MM cartridges).7 selectable impedances from 10 to 1000 Ohm (for MC cartridges).3 unbalanced stereo cartridge inputs via RCA.3 balanced stereo cartridge inputs via XLR.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. 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. Otherwise I could conceivably blow out my woofers.The PPA Violectric PPA V790 is a state-of-the-art phono preamplifier with absolute unsuspected features until now. I would only use it on a truly terrible warp or outrageous rumble that is on the disk.īut it is nice to know I have it with all that horsepower laying around. The bass gets clean as a whistle but everything sounds very closed in when it is in the circuit. The filter sucks all the separation out off the signal and makes it sound like mono in the bass.Īnd it completely alters the tone of the set. SUBSONIC FILTER & BALANCE CONTROL The Alva Solo will even work if. ATTENTION TO DETAIL The Alva Duos switch mode power supply and. DESIGNED FOR VINYL Cambridge Audio’s Alva Solo is a dedicated. I can't remember using my subsonic filter at any time during the last year. Cambridge Audio Alva Solo Phono Preamp for Moving Magnet Turntable. I'm not bragging on hot air-I am a professional installation guy and retired after 40 years in the trenches.Īnd the table feet are then floated again on their own silicon pads for TOTAL isolation from vibration at ANY volume my main system can put out (measured 105dB on "All Along the Watchtower by Hendrix"). It is so quiet you think the record is really a CD. Records are normally dead quiet on the quiet passages-zero rumble, hiss and just a tiny bit of groove scrape. It tests +-3dB down to the low 20s in room using test microphone at listening position. I have a KAB subsonic filter on my far field system that can be switched in or out of my tape monitor loop when I need it.Īnd dual 15 inch Velodynes under those for truly deep bass. ![]()
