UNISON RESEARCH PHONO ONE Pre amplifer Phono Classe A MM MC

Unison Research PhonoOne preamplifier in class A PHONO ONE maintains the original aesthetic, circling 10 triode (ECC83 / 12AX7 dual triode). gain stages with parallel configuration that limits the distortion. I reached 54 dB allows you to use all the heads MM (moving magnet) and most of the MC cartridges (Moving Coil) . passive RIAA equalization network guarantees the standard curve. Muting function delayed eliminates bump and the continuing tensions in the warm-up and the shutdown, so the output is not active until the temperature of the valve operating point. In the case of pick-up with impedance values ​​not usual you can insert a resistance value to be chosen in the slot specifically left free. Each gain stage is provided with an independent RC filter cell which reduces the cross-talk of over 20dB. In PhonoOne the low frequency cross-talk reaches -90dB . The PhonoOne reaches maximum performance, detail and naturalness of sound.
