Creek EVOLUTION 50P Power Amplifier


Product Description

The EVOLUTION 50P is the most sophisticated and reasonably priced Power Amplifier Creek has made. It provides stunning audio performance and is capable of out-performing other makes of Power Amplifiers costing many times the price.

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.
