Evolution 50A
Amplifier


This new amplifier forms part of the next generation EVOLUTION 50 range of products. Housed in a slim case with engraved front panel and solid control knobs, its finished in either black or silver brushed aluminium. An ingenious new push button design has been developed for it, offering excellent tactile feel and backlit optical indication of usable functions for optimum user-friendliness.

This is Creeks first product to feature an OLED (Organic Light Emitting Diode) display. This white on black display provides higher clarity and resolution than a normal display. Brightness levels can be changed or the display made to turn off when not required, via the menu system.

At the heart of any good amplifier lies a good power supply; The EVOLUTION 50A uses a 200 Watt toroidal mains transformer with separate windings for high and low current analogue and digital circuitry. This solution produces a good power to weight ratio and low magnetic interference. Creeks policy of paralleling several low impedance capacitors to create an ultra-high specification capacitor to smooth the DC also helps to produce a very powerful and accurate sound from such a relatively small amplifier.

Creeks Senior Engineer David Gamble has much experience in the audio industry. He has developed a completely new bi-polar transistor power amplifier circuit especially for the EVOLUTION 50A with very high open-loop gain and low distortion. Featuring a pair of Sanken 15Amp power transistors, with built-in thermal compensation for rapid bias tracking performance, the Power Amplifier circuit has very low output impedance and can produce high output current. This combination will provide exceptional speed and control over most loudspeakers.
