ℹ Product Information
POWERFUL, HIGH PERFORMING, SLEEK AMPLIFIER
The perfect blend of performance and power. Both classy and class-leading - the 350 is a high-power, fully-balanced, 350 Watts RMS per channel, hybrid Class A/AB stereo power amplifier featuring power MOSFET technology, dual speaker binding-post pairs, two remote trigger inputs and both Balanced (XLR) and Unbalanced (RCA) inputs.
Available in dragon red or black.
Features:
- Bi-Wiring - The 350 features two pairs of high-quality speaker binding posts per channel; provided for bi-wiring applications.
- Multiple protection systems - The 350 incorporates dedicated protection circuitry, isolated from all signal carrying circuits via opto-couplers providing a range of electronic and speaker safety functionality.
- Soft-start - The 350 utilises soft-start circuitry to protect the fuses and/or circuit breaks in your home's mains power supply when powering on the 350 amplifier.
- Toroidal Power Transformer - The 350 incorporates a high performance, custom-designed, toroidal power transformer. The power supply filter capacitors have exceptionally low inductance and internal resistance. An electrostatic shield prevents AC line borne interference from entering the signal path and the wiring from the power supplies to the output boards is designed for unimpeded transmission of the required current and voltage and utilizes heavy-gauge, tinned copper cable.
- I/O options - 1 pair Unbalanced Inputs (RCA), 1 pair Balanced Inputs (XLR), 2 pairs Speaker Binding Posts per channel, 2 Remote Trigger Inputs (5VDC).
- Hybrid Class-A/AB - The bi-polar transistors used within the 350 operate in Class A. This avoids crossover notch distortion and the resulting odd-order harmonics often present in other classes of power amplifier. The 350 output stage employs power MOSFET transistors, which with high quiescent current circuitry are run in the equivalent of Class-A to 10 watts. Beyond this output level the 350 operates as a hybrid Class-AB power amplifier. The combination of MOSFET characteristics and their application in this circuitry, results in a high power output with extremely low crossover distortion.
- Built to last - Mechanical strength, reliability and longevity have always been the hallmarks of Perreaux’s amplifier designs. The 350 is a rugged, powerful, high performance stereo power amplifier designed to drive the most challenging of speaker loads with minimal effort. Buy one for life.
The PERREAUX 350 stereo power amplifier provides power for the musical purist. This classic, robust, Class A / AB amplifier exudes the crystal-clear, full-bodied and detailed signature sound our PERREAUX power MOSFET amplifiers are renowned for.
