RUBY DAC

DAC, BT, FM RDS Module

Leaflet - Instructions - Images

Creek’s EVOLUTION 50A and EVOLUTION 100A amplifiers are normally supplied with 5 analogue inputs. However, Line input 5 is mounted on a removable panel, so it can be swapped with a tuner or DAC module, to add several more inputs. The RUBY DAC module contains 4 x SPDIF inputs for both optical and co-axial connection. In addition it has a USB input, to stream audio content to the amplifier from a computer and control it via the EVO remote control. To maintain the best sound quality from your amplifier, the RUBY DAC module uses a top of the range Wolfson WM8742 DAC chip, designed in Scotland.

For mobile applications, the RUBY DAC also adds the highly useful feature of Bluetooth connectivity to the amp, via the RUBY DAC. So smart phones or tablets can be synced to the amp and your favourite music streamed wirelessly. In addition to this surprising amount of connectivity in such a small module, Creek have also incorporated the same FM tuner circuit, used in the brilliant AMBIT module, to provide FM connectivity to the RUBY DAC. Sound quality is further improved over the AMBIT module by selecting the tuner’s digital output and converting that to analogue via the RUBY’s own high-end DAC. For details of the radio performance etc. Please read the AMBIT module page for more details. FM radio performance is limited only by the quality of the studio signal and of course the antenna used. Choose an external antenna for the best results.
