The optional PH-2 phono board for the REVO IPA-140B amplifier adds the functions of impedance adapter, RIAA equaliser and preamplifier to the device, in order to receive the signal from a turntable.
It has the peculiar characteristic, and probably the only one of its kind, to be made in dual mono configuration: the two channels are placed on two independent bases, and the power supply is separately stabilised and filtered, to guarantee the best possible quality.
It is able to accept signals from both mobile coil (MC - Moving Coil) and mobile magnet (MM - Moving Magnet) detectors, simply by quickly and practically replacing an integrated circuit (supplied). It is possible to vary the load seen by the head through a switch, which allows you to choose between four default resistance values ​​(100.500, 1K, 47 Kohm) and a value that can be set by the user, by inserting a resistance.
Even the gain value is variable with a similar system, proposing a range from 34 dB to 52 dB in six steps, plus a user-definable value, always by inserting a resistance.
The boardPH-2 is made with very low noise components, sized both for sound detectors with a relatively robust output, and for heads with lower sensitivity.
Equipped with a very accurate layout that makes setting operations simple, this tab allows you to better appreciate the expressive nuances of an analog source, without compromising its natural characte
