SPL Performer m1000 Power Amplifier (Silver)

The SPL Performer m1000 Power Amplifier is a completely analog amplifier easily controls any loudspeaker. Thanks to the VOLTAiR technology the performance of the m1000 is detail-rich, vivid, honest and plain simply beautiful.

The Performer m1000 has a protection circuit against DC voltage and against overheating. If direct current (DC) is detected, the output stage switches off automatically and the Protect LED lights up red. To protect the m1000 against the unlikely event of overheating, a temperature sensor at the heatsinks continously monitors the temperature of the device. The TEMP LED lights up yellow when the Performer m1000 is getting too hot. As a result of this the output stage is switched off and the fans run on high-speed until the device has cooled down.

Power to the speakers
The loudspeaker binding posts can accommodate banana plugs as well as a stranded wire with a diameter of up to 4 mm. Thus, any common type of speaker cable and in bi-wiring mode even both connection types can be used together. However, we do not recommend connecting a speaker with less than 2 ohms impedance.

A class of its own
Conventional solid-state power amplifiers tend to operate in a critical range of the built-in components – this results in unpleasant harmonical artifacts. Tube power amplifiers also distort at their limit but their characteristical behaviour softens this roughness and harshness. Non the less this is a falsified representation of the sound image. Thanks to VOLTAiR Technology, the Performer m1000 can process much higher levels without even coming near to a critical range. All components constantly operate in the optimal range. The result is a very pleasant, natural and relaxed sound experience. Enjoy your music in every detail and without any listening fatigue.

Full power
The Performer m1000 features individual amplification stages for voltage and power amplification, which ensures a perfect operating of the class-AB amplifier circuit.Thanks to each stage’s own negative feedback path, it is ruled out that feedbacks from the loudspeaker are interacting with the input stage – this way the SPL VOLTAiR Technology can play out its full performance.

Keep cool
Inside the Performer m1000, six fans usually do nothing at all, because 90 % of the heat is passively dissipated via massive heat sinks. Should it nevertheless become really loud for a really long time, the processor-controlled fans remain virtually inaudible at only 19 dB (A). During power-up, the fans of the Performer m1000 briefly rotate at a higher speed to remove dust of themselves and surrounding components.

The VOLTAiR Technology
The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology. The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers. The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience. By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed. The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
