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 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.
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, SPL 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.
