Rated 0/5 (Not Rated)


The HV-32P contains two simple HV-32 mic preamp stages, while the HV-35P contains a single HV-35 preamp with front-panel instrument input. Both units are housed in the same neat aluminium case, which measures 144 x 43 x 208 mm (WHD) and weighs 740g. These dimensions equate to one-third rack width and 1U high, so three units can be mounted alongside each other on a rack shelf if required. The top and bottom plates overhang the operational controls at the front, and the connector latches at the back, providing some very useful transit protection. Internally, the two models are built around the corresponding rack module card (or cards, in the case of the HV-32P), along with a bespoke DC-DC power-supply board along one edge, which feeds ±16V power rails.
Each of the MV-32P’s two simple preamp channels is equipped with a rotary gain control, spanning a nominal 15 to 60 dB range, and a traffic-light trio of LEDs below the knob indicates the output signal level (green above -30dBu, yellow at +8dBu and red at +18dBu). Three illuminated push-buttons select a 14dB output pad, engage phantom power, and activate the ‘ribbon mode’. The last of these boosts the gain by 10dB, disables phantom power, and provides a DC-coupled input connection — all to provide the ideal input configuration for dynamic microphones in general, and ribbon mics in particular.
