Clipping 

Indicators 

Each of the six channels of the 6160 have an independent LED indicator which
will illuminate if the output approaches clipping, potentially causing damaging
distortion and is a warning to reduce volume to the indicated channel(s). 

Caution!  When the clip indicator illuminates, that channel is approaching clipping.

This should be avoided, as clipping is the main reason for damage to
both amplifiers and loudspeakers. 

Bridgeable 

Outputs 

The 6160 has the facility to combine two independent channels into a single
higher output channel.  The bridging switch allows the selection of two
independent channels, or the combining of two channels to form a single higher
output channel.  Bridged channels offer considerably more power than two
channels individually. 

Protection 

Systems 

AC Sense 

The 6160 monitors the AC voltage at the secondary windings of the toroidal
transformer, that in turn supply the rectification stages.  In the event that the
toroidal transformer AC output should fail, the protection circuitry will
disconnect the output.  The output will be reconnected once the AC voltage has
been restored. 

DC Rail Fuse 

Each of the +VE and –VE DC rails supplying the output stages of each channel
are protected with a fuse.  In the event that any one of the fuses should fail, the
protection circuitry will automatically detect the fault and disconnect the output
of the respective channel(s). 

Earthing 

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

Earth 

Isolation 

Switch 

The toggle switch on the rear of the 6160 allows the internal circuitry to be
isolated from the mains earth, whilst still maintaining an earth connection to the
chassis.  This ensures the potentially fatal practice of using an AC cord-set with
no earth connection, to alleviate system hum, is not required. 

Highest 

Quality PCBs 

and 

Components 

Quality fiberglass PCBs, featuring heavy copper tracks and high-grade
components, are used throughout the 6160.  This provides added stability under
variable thermal or electrical loads and assures maximum signal integrity,
separation and product life. 

Soft-Start 

Circuitry 

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 60,000µF of power supply capacitance can blow the fuses
or trip the circuit breakers. 

Highly 

Powered 

Capable of continuously delivering 160W

RMS

 into 8

 (225W

RMS

 into 4

), the

6160 is highly powered.  Utilising six high current Hitachi MOSFETs per
channel, the 6160 handles even the most difficult loads with ease.
