Mono Power Amplifier
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.

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 power supply is equipped with a capacitance of 100,000 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.
If DC is detected at the output, the amplifier automatically switches off. DC voltage can be an indication for a defect in the power stage or can be induced by other equipment. The Performer m1000 does not automatically switch on again. It needs to be disconnected from the power (on/off). The Protect-LED on the front illuminates red indicating that the protection circuit is activated and the power stage has been switched off.
To protect the output from overload a limiter will be deployed in case the input level is so hot that the output stage will overload. The limiter operates with a so-called LDR which is a light-dependent resistor. This means that the regulating process is in the photo-optical domain and does not affect the audio signal. Only the result of the processing, a resistor value, affects the audio. The Protect-LED on the front illuminates yellow when limiter is working. The Performer m1000 keeps on playing.
This coil prevents the possibility of oscillation of the power stage. This oscillation can be a result of certain speaker specification. With the Mundorf coil in place a huge variety of speakers can be operated seamlessly.
At about 50°C /112°F at the heat sink, the amplifier will engage the processor-controlled fan cooling. In the unlikely event that the fan is not capable to cool the power transistors or in case the fan is defective the power amplifier will switch off at 85°C/185°F at the heat sinks. The TEMP LED on the front indicates the overheating. Once the temperature falls below 55°C/131°F the Performer m1000 switches on automatically.
The input can be lowered via a Trim rotary switch from 0 dB to -5.5 dB in 0.5 dB steps. This is useful in order to achieve an optimal stereo sweet-spot in acoustically suboptimal rooms. In bi-wiring line-ups or in the studio with multi speaker sets it allows to level speakers with different efficiency to equal loudness.
The speaker connectors are gold plated binding posts. The terminals can accommodate both banana plugs, as well as a wire of up to 4mm diameter.
The Performer m1000 comes with three ornamental inlays: in black, red and silver. They can be combined with the chosen color of the main front panel. A neodymium magnet holds the ornamental inlay in place. This allows easy exchange and gives you the unique opportunity to style your power amplifier.
