Powerful Hybrid Class A/AB 350 wpc Power Amplifier
All pre-owned product is tested in our service department and have been passed for sale... and comes with a 90 day warranty!
In good condition - Cabinet has a few small scratches - see pix.- note front panel. Original box and packing are not included, but we will pack carefully. (note: this amp is 66 lbs!)
First introduced in 2008. Made in New Zealand.
Not as well known here in the USA, Perreaux has been making excellent products since 1974, and they are internationally well respected and highly reviewed! Lots of very cool amp technology.
Features:
Balanced and Unbalanced inputs
High power output
Dual binding posts per channel
Multiple protection systems
Advanced PCB design and earthing techniques
Earth isolation switch
Rugged Build Quality: Mechanical strength has been a hallmark of Perreaux products since the company first started production back in 1974. The concept behind the physical design and construction is that each structural member should contribute to both rigidity and performance.
Ultra Stiff Power Supply: The 350 incorporates a massive custom designed, toroidal power transformer, employing unusually heavy gauge wire that reduces copper losses to a minimum. An electrostatic shield prevents AC line borne interference from entering the signal path. The power supply filter capacitors, totaling 60, 000uF (30, 000uF per channel), have exceptionally low inductance and internal resistance.
Hybrid Class-A/AB: The bi-polar transistors used in the 350 are operating in Class-A. This avoids the crossover notch distortion and the resulting odd-order harmonics present, to some degree, in all other classes of operation. The devices used in the 350 output stage are MOSFETs, which with high quiescent current circuitry, are run in the equivalent of Class-A to 10 watts. Beyond this point the output class is technically Class AB (hence the hybrid nomenclature), but with a major difference.
MOSFET Output Stage: The 350 output stage takes full advantage of the unique qualities of MOSFET devices and in many ways they are superior to bi-polar transistors.
All this leads to an absolutely incredible 80 amps per channel drive capability, which allows absolute and consummate control of any loudspeaker.
Multiple Protection Systems: The 350 incorporates a full range of protection circuits, isolated from all signal carrying circuits via opto-couplers. However, these circuits are aimed at ensuring an extremely high safety margin for these high-powered products rather than as a mandatory addition to correct for poor or overloaded circuit topologies.
