The Performer m1000 is the big brother of the highly acclaimed Performer s800. Built as a mono block it features SPL's proprietary VOLTAiR technology that allows creating power amps with far less components in the signal path than common designs. Only one preamplifier op-amp is required to drive the bipolar power amplifier transistors: extremely fast, direct, highly efficient and with an extraordinary sound.The Performer m1000 delivers 1000 W into 2 ohms or 750 W into 4 ohms out of a linear power supply with a massive toroidal transformer. The Performer m1000 amplifier is an ultra-compact power amplifier. Thanks to the VOLTAiR technology this power amplifier has absolute control over the speakers up to their load limits. Designed as a mono block amplifier this bi-polar transistor power amplifier delivers up to 1000 W into 2 ohms, 750 W into a 4 ohms and 420 W into 8 ohms speaker. The Performer m1000 is equipped with a slave-through XLR output and an input trim switch.The Performer m1000 is equipped with a 1375 VA toroidal transformer. After many listening tests we are convinced that a fully analog power amplifier with a power supply built around a toroidal transformer sounds superior to digital amplifiers and power amplifiers with switch mode power supplies. The power supply is equipped with a capacitance of 54400 µF for screening and electricity storage and a faithful reproduction of impulse peaks. The toroidal transformer is mounted on a separate mounting plate that sits on 8 rubber dampers to extenuate any mechanical hum noise.
