Specifications
Explained
Rated Power Output............................................................... 750W
RMS
into 8Ω
The 750 has been designed around the industry standard 8Ω load. The 750
delivers a staggering 750W
RM S
continuously into 8Ω loads and 1300W
RM S
into
4Ω loads.
Frequency Response .................................................... 5Hz to 40kHz ±0.25dB
This is the “standard” specification with which everyone is familiar. Actually,
“frequency response” is a misnomer: technically, it should be called “amplitude
response versus frequency” for it describes how uniform the amplitude or
strength of signals of various frequencies is maintained. It is generally thought
that a difference of 1db is the least that can be perceived by ear. To better that
by a wide margin, the 750 is specified four times higher, thus far exceeding the
audible range of the human ear.
Total Harmonic Distortion
(THD+N)
........................... 0.008%, @ 1kHz into 8Ω
M easurements are made with fixed, purely resistive loads. However, since
speakers are not purely resistive, an amplifier’s distortion specifications do not
indicate what performance will be with the actual loads presented by speakers.
Perreaux distortion measurements hold for any conditions presented by any
known speaker. Further, any measurable distortion in the Perreaux is second-
order harmonics – the least offensive to the ear.
Voltage Gain............................................................................................. 34.3dB
