Stereo Power Amplifier

This small stereo power amplifier shows everyone that size does not necessarily have anything to do with greatness. With the power of 570 W it has every speaker under control. Thanks to VOLTAiR technology, it is fast, precise and highly efficient with outstanding sound.

Better safe than sorry

The Performer s800 has a protection circuit against DC voltage and a limiter against output overload.

If direct current (DC) is detected, the output stage switches off automatically and the Protect LED lights up red.

To protect the output against overdriving, an LDR limiter (light-dependent resistor) is used. Since it works optically, the audio quality is not affected. The Protect LED lights up yellow when the limiter responds.

As one calls into the forest,

so it echoes out.

This saying inspired us to send the input signal out again in order to drive another power amplifier in bi-amping mode.

Trim to fit

With reference to the s800, “fit” means adapted. And you can adapt the input sensitivity in 0.5 dB steps. From 0 dB to -5.5 dB.

This is the much more audiophile solution for acoustically problematic rooms or loudspeaker set-ups than the panorama potentiometer of the preamplifier.

In addition, the difference in loudness of loudspeakers can be elegantly compensated in bi-amping mode.

Plus & Minus

The loudspeaker binding posts can accommodate banana plugs as well as a stranded wire with a diameter of up to 4mm.

For bi-wiring operation, both types of connection can be used together.

No loudspeaker with less than 4 ohms impedance may be connected.


The power amplifier can be switched on and off using the AMP CTL connection between the Performer s800 and a preamplifier such as the Director Mk2 or the Crossover.

To do this, connect the 3.5 mm jack sockets with a cable with 3.5 mm mono or stereo jack plugs.

Third-party preamps can also switch the Performer s800 on and off with their 12 V trigger.
