Creek Audio - Evolution 100P

Who needs a power amp?  Well, you do, if you use a digital or analogue pre-amplifier like the EVOLUTION 50CD or 100CD, with built-in volume control.  It is also possible you already own an integrated amplifier like the EVOLUTION 100A and wish to bi-amp your system to power difficult loudspeaker loads.

The new Creek power amplifier forms part of the new generation EVOLUTION 100 range of products. Housed in a slim case with engraved front panel and solid control knobs, it’s finished with either a black or silver brushed aluminium front panel.

The EVOLUTION 100P uses a massive 350 Watt toroidal mains transformer with separate windings for high and low current analogue and control circuitry. This solution produces a good power to weight ratio and low magnetic interference. Creek’s design policy of connecting several small low impedance capacitors in parallel creates an ultra-high specification capacitor to smooth the DC and helps to produce a very powerful and accurate sound from such a relatively small amplifier.

This power amplifier has a similar high-end, bi-polar transistor, Class-G power amplifier circuit, to the highly rated EVOLUTION 100A.  It achieves very high open-loop gain and low distortion for a smooth and powerful sound. Featuring Sanken 15 Amp power transistors, with built-in thermal compensation for rapid bias tracking performance, the EVOLUTION 100P Power Amplifier circuit has very low output impedance and is also able to deliver high output current. This combination will provide exceptional speed and control over most loudspeakers.

A simple unity gain pre-amplifier selects between balanced XLR and direct un-balanced RCA inputs, to enable the user to input two different signals and select between either, on the fly, if required. It is fully protected from over-current, over-temperature and DC faults and will trigger the output and input relays to disengage immediately if an error occurs.

When required, the Evolution 100P can also be configured as bridged-mono to achieve even higher power output and will therefore sound more dynamic and in control. Please consult Creek Audio or your dealer for details about the external bridging adapter required to simply convert it from stereo into mono operation.
