Voltage Gain | 30.7dB |
The amount of amplification the amplifier is asserting on the input signal. Gain can be calculated by dividing the rated output by the input sensitivity.
Dynamic Headroom | >1.1dB |
This indicates the 350 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 |
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.
Maximum Current Output | 80A per channel |
Current is the power reserve in the amplifier necessary to deliver the burst of voltage required by the
Damping Factor | >700, @ 1kHz into 8Ω |
Another specification not always provided. One reason perhaps, this specification is important when indicating an amplifier’s ability to control the cone behaviour 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) | 100dB |
The ratio of desired signal to noise signals present in the output. This figure is referenced to the rated output of the 350, taking into full account all potentially annoying hum components.
Input Sensitivity | 1.5VRMS |
Indicates the amount of input voltage required to drive the unit to its rated output power (350WRMS into 8S).
Input Impedance | 22kΩ |
The resistance “load” that is presented to the component that is driving it. The high value indicates that the power amplifier will not load down the output of most high quality preamplifiers.
