Creek EVO 2 Features
-
To achieve 80 Watts power into an 8 Ohms load and >140 Watts into 4 Ohms, the mains transformer has to be big. The Evolution 2 uses a 250VA toroidal transformer, which will provide enough current to almost double its output into 4 Ohms. To achieve high-end sound quality, no expense has been spared.
-
Separate windings are used for each of the high current high voltage and low voltage, analogue and digital circuits. A high capacity power supply using 20,000 micro-Farads of multiple smoothing capacitors are used to power the left and right power amplifiers and provide a very dynamic performance.
-
The Evolution 2 uses a high quality, Burr-Brown PGA2311, digitally controlled analogue volume control. This allows the user to adjust the volume accurately, from 0 to -80dB. An analogue style rotary encoder, with 40mm solid control knob, is used to alter the volume from the front panel and display the relative level on a large blue coloured VFD. Position 80 is the loudest and 0 is mute. To amplify the signals into the volume control circuit, a high grade Burr-Brown OPA2134 Op-Amp is used as a pre-amplifier. Signal switching is performed by gold contact relays, which are digitally selected from a microcontroller, similar to the Destiny Integrated Amplifier.
