Performer m1000 Mono
Power Amplifier

Includes black, red
and silver ornamental inlays!

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.

Ultra-compact power

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.

Toroidal transformer

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

The power supply is equipped with a capacitance of 54400 µF
for screening and electricity storage and a faithful reproduction of impulse

The toroidal transformer is mounted on a separate mounting
plate that sits on 8 rubber dampers to extenuate any mechanical hum noise.


The Performer m1000 has a protection circuit against DC
(direct current) voltage at the output and a limiter against overloading the

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

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.

Custom-made Mundorf

The Performer m1000 is equipped with a custom 3,8µH coil
made by German high-end specialist Mundorf. 

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

Processor controlled

Heat dissipation is done with a micro-processor controlled
fan cooling that only gets activated when the internal temperature exceeds
certain limits. In standard operation the fan may not even start working at
all. But if so, the fan speed and thereby its noise level is temperature

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.

Input and output

The Performer m1000 is equipped with Neutrik XLR input and
output connectors for balanced operation. The input signal is passively routed
to the output connector to feed e.g. a second power amplifier for

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

Amp control

The Performer m1000 has a 3.5mm mono jack designated as AMP
CTL (amplifier control). With the appropriate cable, the Performer can be
connected to a preamplifier, so that when you turn the preamplifier on the
amplifier is automatically switched on, too. In our Pro-Fi series the Director,
Phonitor x and the Crossover provide AMP CTL ports.

Variety of colors

You can customize the look of your Performer m1000! 

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.
