Perreaux Prisma 350 owner manual Voltage Gain 30.7dB

Page 35

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

197Vp-p

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 ever-changing audio signal. With more than adequate continuous current per channel and high volts peak-to-peak, the 350 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

>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.
