Creek Evolution 2 Amplifier | Creek Amplifier
Creek Evo 2 Amplifier - is a remarkable design, delivering form AND function, without scrimping on the most important ingredient in any good hifi – sound quality.
Significantly, the Evolution 2 is the first product made by Creek to use an electronic volume control. It uses a Burr-Brown PGA2311, stepped resistor attenuator operated by a microcontroller. This allows the user to adjust the volume accurately, in 1 dB steps, 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 reverse level in dB on a large blue coloured VFD display i.e. 80 is loudest and 0 is off. To buffer the signals in and out of the pre-amp, high grade Burr-Brown OPA2134 op-amps are used. Signal switching is performed by relays, which are driven by signal from a powerful microcontroller, similar to the Destiny amp.
To keep the amplifier safe, it is monitored by discrete transistor circuitry to protect against over current demand, short circuits and DC offsets. Relays mute the input and separate the loudspeaker output in the case of faults.
Mains connection is via a standard, fused, IEC chassis plug. A high quality power cord, with suitable mains plug for the country of use is supplied.
