Primare A33.2

High Current Dual Mono Balanced Power Amplifier. 2 x 120 W RMS 8 ?,

The A33.2 is a two channel dual/mono power amplifier that provides a level of performance that eclipses even Primare’s acclaimed A30.2 design.

Its dual-mono design provides a dedicated mono amplifier for each channel incorporating a heavy-duty custom-made toroidal transformer and low noise regulated power supplies. Each uses four ultra-fast bi-polar output devices in a push-pull configuration to preserve perfectly the fidelity of musical transients and minimize distortion.

The heat sinks are massive to keep the temperature at a moderate level even under the most difficult working conditions. The amplifier, which is capable of delivering 120watts into an 8ohm load and over 200W into 4ohm, incorporates full speaker protection against faulty input signals. One individual DC-servo for each channel together with protection circuit and temperature monitoring provide state-of- the-art protection.

The A33.2 can be connected conventionally via RCA sockets or in balanced operation via its XLR connections. Massive high quality gold plated speaker terminals are also specified.

The A33.2 is flexible enough to be used with the PRE30 pre-amplifier, SP32 AV Processor or as a substantial 7.1 upgrade for the SPA22 integrated AV amplifier. The amplifier can be remotely operated via its 12V trigger input, which has a loop-through output for controlling a second A33.2 or other amplifier.

As with all Primare units, the A33.2 is housed in a heavy gauge (2 mm) steel chassis, which provides strength, rigidity, and screening, while being effective at damping vibrations from external sources.

   Head to Head: Pre30/A33.2
Primare's 'new' pre/power combo of Pre30 and A33.2 power amplifier has gained the best marks (80%) for sound quality in a group test published in Hi Fi News' September 09 edition. In collecting a 'Highly Commended' badge the Primare combo was 'assured and supremely confident in all areas of performance' and tracked 'dynamic swings in the music to make for a rousing sonic event.' It concludes that 'with its transparent, dynamic and involving sound to match the satisfying build quality, this pair more than justifies its price tag. Indeed it was judged to be the equal of the Levinson amplifier used as this month's benchmark'.
