Dynamic Headroom........................................................................................>1.5dB
This indicates the 6160 can provide more than enough extra power to cope with
the sharpest musical transients. Without adequate headroom, an amplifier can
become unstable under clipping conditions. Perreaux amplifiers are intrinsically
stable under all dynamic conditions.
Voltage Swing..................................................................................................160V
p-
p
Loud transients call for a sudden burst of power from the amplifier to drive th
e
speakers. This force is voltage. Peak to peak voltage is a more usefu
l
specification than Watts when it comes to delivering power to a speaker.
Maximum Current Output..........................................................24A per channel
Current is the power reserve in the amplifier necessary to deliver the burst o
f
voltage required by the ever-changing audio signal. With more than adequat
e
continuous current per channel and high volts peak-to-peak, the 6160 can easil
y
meet any challenge music can present to it – whether instantaneous o
r
continuous. To be specific it can deliver high power into low-impedance loads
and provide great dynamic headroom.
Damping Factor.................................................................... >500, @ 1kHz into 8
Ω
Another specification not always provided. One reason perhaps, this
specification is important when indicating an amplifier’s ability to control the
cone behavior of speaker systems, which are difficult to drive. Perreaux power
amplifiers have high damping factors. Thus exerting massive control over the
speaker system.
Signal to Noise Ratio
(unweighted)
......................................................................95dB
The ratio of desired signal to noise signals present in the output. This figure is
referenced to the rated output of the 6160, taking into full account all potentiall
y
annoying hum components.
Input Sensitivity................................................................................................1.3V
RMS
Indicates the amount of input voltage required to drive the unit to its rated outpu
t
power (160W
RMS
into 8Ω).
Input Impedance................................................................................................. 36k
Ω
The resistance “load” that is presented to the component that is driving it. Th
e
high value indicates that the power amplifier will not load down the output o

most high quality preamplifiers.
