SPL Performer m1000 Monoblock Power Amplifier

With its appearance, the SPL Performer m1000 mono power amplifier fits perfectly into the SPL “Professional Fidelity” HiFi product line – and is of course available in the three basic colors black, red or silver. In addition to the choice of the basic color black, red or silver, there are three more options for each to customize the Performer m1000 to individual design preferences with the black, red and silver decorative panels included in the scope of delivery. The decorative panels adhere with the help of a strong neodymium magnet. No tools are required to exchange them.

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.

With reference to the Performer m1000, “fit” means adapted. You can adapt the input sensitivity in 0.5 dB steps from 0 dB to -5.5 dB. In contrast to a panorama potentiometer in a preamplifier, this trim switch is the more audiophile solution. In addition, the difference in loudness of loudspeakers can be elegantly compensated in bi-amping mode.

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 can be used. However, we do not recommend connecting a speaker with less than 2 ohms impedance.

The standby mode of the power amplifier can be switched on and off using the AMP CTL connection between a preamplifier such as the Director Mk2. To do this, connect the 3.5 mm phone jacks with a cable with 3.5 mm mono or stereo jack plugs. Thanks to its 12 V trigger input, third party preamps can also switch the Performer m1000’s standby mode on and off.

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.

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.

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 s1200 briefly rotate at a higher speed to remove dust of themselves and surrounding components.

With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.
