Evolution 50P Power Amplifier

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 50A and wish to bi-amp your system to power difficult loudspeaker loads.

This new 55W (into 8 Ohms) power amplifier forms part of the new generation EVOLUTION 50 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 50P uses a massive 200 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 A/B power amplifier circuit, to the highly rated EVOLUTION 50A, also developed by David Gamble.  It achieves very high open-loop gain and low distortion for a smooth and powerful sound. Featuring a pair of Sanken 15Amp power transistors, with built-in thermal compensation for rapid bias tracking performance, the EVOLUTION 50P 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 select 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.
