The Performer s800 Stereo Power Amplifier from SPL 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. Free shipping to Continental US only!
In stereo operation, this bi-polar transistor power amplifier delivers up to 2 x 285 watt into 4 Ohms speakers. In Bridge Mode it delivers 450 watt into an 8 Ohms speaker. In addition, it is equipped with slave-through outputs and input trim switches.
The Performer s800 amplifier uses the VOLTAiR technology ( 120V rail technology ) to offer a high voltage of 120V ( +/-60 VDC ) and large dynamic range of over 140 dB. The 120V electronics operate quasi 'idle' even at highest audio levels and impulse peaks. They never operate on the limit and therefore never get stressed. The music presents itself with serenity so that you feel pleasant when listening.
The amplifier is equipped with an 855VA toroidal transformer. The power supply is equipped with a capacitance of 40800 µF for screening and electricity storage for faithful reproduction of impulse peaks.
The Performer s800 amplifier has a protection circuit against DC voltage at the output and against overheating. At about 158°F at the heat sink, the amplifier will switch off. After the temperature has fallen below 131°F, the amplifier automatically switches on again. The temperature LED at the front indicates the overheating.
If DC is detected at the outputs, the amplifier automatically switches off. DC voltage can be an indication for a defect in the power stage. The amplifier does not automatically switch on again. It needs to be disconnected from the power ( on/off ). The Protect LED at the front indicates that the protection circuit is activated and the power stage has been switched off.
The amplifier is equipped with Neutrik XLR input and output connectors for balanced operation. The input signal is passively routed to the output connector to feed a second power amplifier for bi-wiring. The input can be lowered via a Trim rotary switch from 0 to -5.5 dB in 0.5 dB steps. This is useful in order to achieve an optimal stereo sweet-spot in acoustically sub-optimal rooms. In bi-wiring line-ups or in the studio with multi-speaker sets, it allows for leveling speakers with different efficiency to equal loudness.
The speaker outputs are gold plated binding post connectors. The terminals can accommodate both banana plugs, as well as a strand of up to 4 mm diameter. To protect against short-circuits, the binding post is equipped with a clear plastic cap.
The Performer s800 amplifier features a 3.5 mm mono jack designated as AMP CTR ( amplifier control ). With the appropriate cable, the amplifier can be connected to a pre-amplifier. This automatically helps in switching on the amplifier when you turn on the pre-amplifier.
