Dynamic Headroom........................................................................................>1.9dB
This indicates the E160 can provide more than enough extra power to cope wit
h
the sharpest musical transients. Without adequate headroom, an amplifier ca
n
become unstable under clipping conditions. Perreaux amplifiers are intrinsicall
y
stable under all dynamic conditions.
Voltage Swing..................................................................................................156V
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 of
voltage required by the ever-changing audio signal. With more than adequate
continuous current per channel and high volts peak-to-peak, the E160 can easily
meet any challenge music can present to it – whether instantaneous or
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 th
e
cone behavior of speaker systems, which are difficult to drive. Perreaux powe
r
amplifiers have high damping factors. Thus exerting massive control over th
e
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 E160, 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 power amplifie
r
section to its rated output power (160W
RMS
into 8Ω).
Input Impedance................................................................................................. 22k
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
f
most high quality preamplifiers.
