General Features

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 6160 incorporates a massive custom designed toroidal power supply 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, have exceptionally low inductance and internal resistance. They charge and discharge in response to load demand far more rapidly than conventional storage capacitors and are capable of delivering the instantaneous current required by the output stages, providing optimum dynamic range and transient response. 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 wire cables. Since power supply leads radiate at signal frequencies, all wiring is carefully loomed to minimise this effect.

Hybrid Class-A/AB

The bi-polar transistors used in the 6160 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 6160 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. The combination of MOSFET characteristics and their application in this circuitry, result in crossover distortion so minimal that it is virtually non-existent.

Bridgable Outputs

All channels on the 6160 are bridgeable, enabling 3, 4, 5 or 6 channel operation. Bridging two channels increases the continuous power output from 160Wrms to 425Wrms into 8Ω.

Earthing

We pay particular attention to designing the product to ensure maximum separation between internal signal and power earths, only meeting at a central starred point.

MOSFET Output Stage

The 6160 output stages take full advantage of the unique qualities of MOSFET devices and in many ways they are superior to bi-polar transistors. A major advantage is their tendency to draw less current over a large section of the power bandwidth as their temperature rises (Negative Temperature Coefficient), hence self stabilising thermally, whereas bi-polar transistors draw more current as their temperature rises (Positive Temperature Coefficient) and protection circuits become mandatory to prevent thermal runaway and eventual self destruction. MOSFETs have the ability to swing fully across the amplifier’s internal DC voltage and are therefore true “rail-to-rail” devices. Using MOSFETs encourages the highest performance from the balance of the internal amplifier circuitry.

Multiple Protection Systems

The 6160 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.

Remote Trigger Inputs

These inputs allow the 6160 to be remotely controlled by a processor or other component, and along with the ability to have all channels bridged, the 6160 can be seamlessly integrated into a current stereo application to create a powerful home theatre system.

Soft Start

The 6160 utilises soft start circuitry to protect the fuses and/or circuit breakers in your home’s mains power supply. Without this circuit, the huge inrush current required to charge the 60,000uF of power supply capacitance, would blow the fuses or trip the circuit breakers.

Highest Quality PCBs and Components

Quality fiberglass PCBs, featuring heavy copper tracks and high quality audiophile grade components, are used throughout the 6160.

Clipping Indicators

Six LEDs located on the front panel indicate if any of the channels are clipping.
