The powerful stereo amplifier
This impressive stereo power amplifier leads even the most demanding speakers to soundscapes beyond your expectations. With a power amplification of 2 x 520 W (4 Ω) [2 x 550 W (2 Ω); 2 x 300 W (8 Ω)], this completely analog amplifier easily controls any loudspeaker.
Thanks to the VOLTAiR technology the performance of the s1200 is detail-rich, vivid, honest and plain simply beautiful.
The Performer m1000 can be equipped with a black, red or silver decorative panel that are included in the scope of delivery. This gives you a choice of three colour variants for your chosen basic colour.
The decorative panels adhere with the help of a strong neodymium magnet. No tools are therefore required for changing them.
Better safe than sorry
The Performer s1200 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 s1200 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 s1200 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.
Freedom of choice
The Performer s1200 features a stereo pair of XLR and RCA inputs. This makes it compatible with all preamps on the market without the use of adapters. The stereo input can be selected via the Input Select switch on the rear panel.
Trim to fit
With reference to the Performer s1200, “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. The optimal operating range of the loudspeakers and preamplifier can be perfectly adjusted this way.
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 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 s1200’s standby mode on and off.
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 s1200 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 s1200 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 s1200, 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. All important components are installed on the circuit boards using THT technology. This way we can ensure that we can use the best sounding components.
Home is where the heart is
That’s why we manufacture all SPL devices in our own production facility in Niederkrüchten on the Lower Rhine, Germany.
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 highest possible audio quality requires the highest possible audio operating voltage.
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.
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.
Most audio devices work with an internal operating voltage of +/-15 volts and can thus process a maximum input level of +21.5 dBu. If a DAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of the music material would already cause overloads in the input stage of the device.
All components in the audio device often operate at their limits. The result is an unsteady sound that causes stress and faster ear fatigue.
SPL devices with VOLTAiR technology can handle input levels of +32.5 dBu thanks to the higher internal operating voltage of +/- 60 volts – thus offering 12dB more headroom. All components consequently operate continuously in the optimum operating range. The result is a very pleasant, natural and relaxed sound experience. So you can enjoy your music in every detail.
