Alva Solo is a phono preamplifier for mobile magnet cell, compact. It brings a gain of 39 dB, a subsonic filter, a scale setting and an automatic shutdown after twenty minutes.
The RCA entrance receives a mobile loving cell on an impedance of 47 kohms and a capabilities of 100 pf. The gain reaches 39 dB to 1 kHz for a nominal output of 300 mV. A dedie mass terminal welcomes the ground wire of the plate, and a balance adjustment corrects a balance between the two channels.
The card is carried out in surface mounting, a choice that shortens the tracks and preserve the signal from the cell. The diet has a decoupage works outside the audible frequencies, which spreads the snoring of the sector. The RIAA curve is followed at +/- 0.65 dB between 30 Hz and 20 kHz and the distortion remains in 0.0025%.
The box measures 17.6 cm wide on 13.2 cm deep and 4.8 cm high. It slides under a plate or has a phono-intensive amplifier. The maximum consumption is 10 W.
The device is coming from itself after twenty minutes without signal. In standby, he consumes less than half a watt. The subsonic filter withdraws the very low frequencies produced by a veil or use disc.
