Creek Evolution 50P Power Amplifier

This new 55W (into 8 Ohms) power amplifier forms part of the new generation Evolution 50P 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 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.

 Creek Evolution 50P utilises a a pair of Sanken 15 Amp power transistors with built-in thermal compensation for rapid bias tracking performance. The circuit has very low output impedance and the ability to deliver high output current. This combination provides exceptional speed and control over most loudspeakers.

The Evolution 50P uses a 200 watt toroidal transformer, the Evolution 50P has a separate windings for high and low current analogue and control circuitry. This solution produced a good power to weight ratio and low magnet interference. Creek's design policy of connecting several small low impedance capacitors in parallel creates an ultra-high spec capacitor to smooth the DC and helps to produce a very powerful and accurate sound from such a relatively small amplifier. 
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.
