Rated Power Output | 750WRMS into 8Ω |
The 750 has been designed around the industry standard 8S load. The 750 delivers a staggering 750WRMS continuously into 8S loads and 1300WRMS into 4S 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 |
Measurements 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 |
