CONCERO's are digital audio processors. They contain advanced algorithms to process digital audio data; each can optionally upsample 44.1kS/s and 48kS/s to four times that rate, (176.4kS/s and 192kS/s) with filters specifically designed by audiophiles to the finest quality available. CONCERO HP & HD support USB PCM data rates up to 352.8kS/s, CONCERO supports up to 384kS/s via USB Audio 2.0. If you are using a Windows PC you may install the Resonessence provided Thesycon driver to enable USB Audio 2.
possible by use of the Apple Remote Control. CONCERO HP does not switch automatically from S/PDIF input to output. Resonessence provides a PC and MAC CONCERO HP configuration utility that allows the user to configure CONCERO HP to always power-on in S/PDIF input or output mode. (This user setting may be changed as many times as required, and is stored in the unit's non-volative RAM chip.) CONCERO and CONERO HD models will stream out PCM data to the S/PDIF output when accepting PCM data via the USB.
Music from PC/MAC via USB In this mode CONCERO will work with your favourite music player application and output analog signals to your pre-amplifier, or headphones, and/or digital signals via S/PDIF to your S/PDIF enabled audio components. If using a Windows computer download the Resonessence USB Audio 2.0 Driver. See page 14 of this document for download and installation instructions. 1: Connect either: 1. The Red and White Audio RCA outputs to your pre-amplifier inputs. 2.
Analog Output from S/PDIF Input In this mode CONCERO will work as a DAC, converting your S/PDIF digital data into high quality audio signals to your preamplifier inputs or headphone output. 1: Connect the Red and White Audio RCA outputs to your pre-amplifier inputs or connect your headphones to the jack plug. 2: Connect your source of S/PDIF data to the Orange RCA input of the CONCERO.
Operation with Apple IR Remote CONCERO HD responds to the Apple IR Remote and provides the following functions. Selecting an up-sampling filter • Initially no filter is applied: the CONCERO processes data bit-perfect. Whatever data is received is sent to the DAC and/or SPDIF unmodified. In this mode the display LED will be Blue while music is playing. You may send USB data at up to 352.8kS/S or 384kS/S. ( Note that if you use DSD data sources Resonessence upsampling filters are not used.

USB Audio 2.0 on Windows Downloading and Installing the Resonessence Thesycon Driver This is needed only for the Windows Operating System. The MAC Operating systems already include USB Audio 2.0. 1: Download this zip file: http://resonessencelabs.com/downloads/USB_Audio_Drivers.zip and unzip the contents into a temporary directory on your computer. 2: If you have had a previous installation of the Thesycon driver you must now uninstall it.
4: Run the “setup.
5: Follow the onscreen instructions to ensure CONCERO is plugged in if you are asked during the installation process and then choose “Next”. Continue to choose “Next” when appropriate, and the installation will complete after a short while.
6: Select the CONCERO as the default audio device.
CONCERO HP Volume Control On the MAC and on Windows, the volume control knob of the CONCERO HP controls the volume in the operating system (it is not a volume control within the CONCERO electronics). For example, on Windows when the CONCERO is the default audio device, the volume control (which is made visible by clicking on the speaker icon on the task bar by the clock) will move as the volume knob is adjusted.
The first time CONCERO HP is used on any of the computer USB ports the volume will be 0dB. We strongly recommend that you plug the CONCERO HP into the USB port with the headphones unconnected, and first set the volume to a much lower level. Again, for each USB port the Operating System (both PC and MAC) will thereafter remember the volume you last used, so this caution only applies to the first time you use CONCERO in any given USB port.
CONCERO Software Updates Resonessence may make software updates available from time to time which will add features to your CONCERO (or correct any problems that may be found in the future). The latest software for all CONCERO models may be found at http://resonessencelabs.com/software-updates-for-concero/ Refer to that link for details, but an overview is given here. CONCERO Software update tools are provided for both the MAC Operating Systems and the MS Windows Operating system.
3. Run the dfuw_concero.exe executable by double clicking it. 4. When prompted by the onscreen instructions, click ‘Continue’ to begin the upgrade procedure. 5. The upgrading process will take several seconds. When complete, unplug the CONCERO from the computer by removing the USB cable. 6. Wait until the dfuw_concero.exe program reports that the upgrade is complete. Once completed, it is safe to exit the program and then use your upgraded CONCERO.
Installing Software updates from a MAC Install “mono” on your MAC. This is a tool that supports C# programs in the MAC environment. To do this go to http://www.go-mono.com/mono-downloads/download.html and choose the MAC version. 1. Download the Zip file from Resonessence at the link on page 20. It will be a file similar to ConceroUpdaterVERX_MAC_OS. Extract the file that is in the ZIP. 2. Connect the CONCERO to your MAC via a USB cable. 3. Run the ConceroUpdater application. 4.
