Voltage swing .................................................................................... ±80V
p-p
Comments
Loud transients call for a sudden burst of power from the amplifier to drive
the speakers. This force is voltage. Peak to peak voltage is a more useful
specification than Watts when it comes to delivering power to a speaker.
The test for power in Watts uses a purely resistive load, even though no
speaker is purely resistive.
Instantaneous output current................................................ 36A per channel
(Electronically current limited)
Comments
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
Perreaux R200i 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.
Channel separation............................................................................> 120dB
Comments
This is another revealing specification. Our result comes from Perreaux
power supply design (effecting the low end) and the care taken in design
and manufacture (effecting the high end). The result is a clear, sharp and
well-defined stereo image.
S/N ratio..............................................................................................> 95dB
(referenced to rated output)
Comments
This is an unweighted figure taking into full account all potentially
annoying hum components. Higher figures can be stated with weighting of
course.
Damping factor ..................................................................................> 2000
Comments
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.
