Amplifier 擴音機 / Primare / A32

Power Amplifier


With the mighty A32, Primare has set foot on truly esoteric ground. This is a massive fully balanced design capable of controlling the most demanding low-sensitivity speakers - even at the very highest volume levels. The specification is impressive. Equipped with a 2kVa toroidal transformer featuring four separate windings, two for each (L/R) channel; a reservoir of 90.000 uF and sixteen bipolar output devices per channel, the A32 is undeniably an elite amplifier in the classic Primare dual/mono mould. Both balanced and unbalanced inputs are provided, as well as twin speaker terminals for bi-wiring, a trigger input and RS232C inputs. If the unbalanced inputs are used the A32 converts the signal to balanced, to take full advantage of its balanced design.
