Primare - A32 Stereo Power Amplifier
Dual Mono Balanced Power Amplifier. 2 x 250W RMS 8 §Ù The A32 is an immensely powerful fully-balanced power amplifier, conservatively rated at 2 x 250 watts into an 8 ohm load and 2 x 400 watts into a 4 ohm load.
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.
At the heart of the A32¡¯s dual-mono topology is a massive 2000VA toroidal transformer featuring four separate windings, two for each (L/R) channel. Double rectifiers per channel are used to create a ¡°floating ground¡± for the best possible galvanic insulation from the mains. The electrolytic bank is 90.000 uF per channel to ensure that there is more than enough power available for even the deepest sonic transient.
The A32¡¯s outputs are fully protected against DC (servo-controlled), high temperature and speaker terminal shorting. Alternative methods of protection, such as current limiting, affect sonic performance when using low impedance speaker loads.
The amplifier incorporates two standby modes. The first is the audiophile standby, in which all the power supplies remain active, only the speaker relays and bias are switched off. In this mode the amplifier will start at optimum performance with no warm-up time. The second mode, suitable for extended periods of inactivity, turns off all analogue power supplies and will therefore require a warm-up period before the A32 performs at optimum levels.
As with all Primare designs, the A32 is housed in a heavy gauge steel alloy chassis, which provides strength, rigidity, and temperature stability, while being effective at damping vibrations from external sources.
Specified to offer a boundless soundstage and effortless dynamics, the A32 enters the world of the elite power amplifier.
