CONCERO HD connects the Resonessence upgradable FPGA based DSP engine to the new 32bit ESS ES9018-2M Sabre DAC for high performance, high sample-rate PCM up to DXD rates (352.8kS/s) from the USB Audio 2.0 port. In addition, it also contains the Resonessence 4x up-sampling filters that will accept 44.1kS/s and 48kS/s data streams from USB or S/PDIF and convert them to 176.4kS/s and 192kS/s respectively.
CONCERO HD activates the ES9018-2M’s internal DSD processing engine to support Direct Stream Digital (DSD64 and DSD128) from the USB Audio 2.0 port using DoP standard version 1.1. CONCERO HD can operate as a USB to S/PDIF bridge in all modes except the DSD128 mode (that more would result in an S/PDIF stream data rate that exceeds the S/PDIF specification. DSD64 however does work, DoP data packets are send out on the S/PDIF in that mode).
CONCERO HD is designed from the ground up to deliver on the promise of Direct Stream Digital in addition to high sample rate PCM. It brings the latest ESS Sabre DAC chips and the latest standards in audio processing to your existing power amplifier and loudspeaker configurations.
- Plug CONCERO into an active USB port and CONCERO enumerates as an audio output device. Now you can use CONCERO with your favorite music player on the MAC or PC, and experience a new level of audio clarity. CONCERO will optionally up-sample your digital 44.1kS/s and 48kS/s provided over the USB, into both an analog output from its internal ESS Sabre DAC’s into your existing audio pre-amplifier inputs or to your headphones. CONCERO (not the HP version) is also capable of generating a 24 bit ultra low jitter SPDIF stream output.
If you prefer to provide your own data at higher than 48kS/s, all CONCERO models will render it bit-perfect into the DAC (and SPDIF stream if not HP) while providing exceptional jitter removal.
- Plug CONCERO into a power-only USB port (of the type used to charge cell phones or similar), and finding no active host, CONCERO will configure to accept SPDIF input. Once again offering to up-sample 44.1kS/s and 48kS/s into high quality 176.4kS/s or 192kS/s, or render it bit-perfect and jitter reduced into to the internal Sabre DAC for your pre-amplifier inputs or headphones.
CONCERO models respond to the Apple IR Remote for you to conveniently control the USB host track selection and play/pause, and on-the-fly select the ideal internal filter to suite your taste. No glitch or artifact is generated during filter switching, allowing you to audit the filters and choose the optimum. Pressing the volume control knob on the HP model also cycles through the filter selections.
*The CONCERO HD and CONCERO HP do indeed use the 32bit ESS9018-2M Sabre DAC but the data you send to our DACs is at most a 24bit word. What then is the reason to mention that the DAC is 32 bits? It is important, and it sounds better when the DAC is 32 bits, because of the signal processing the DAC must do can end up loosing information (ie making a very low level of noise) if the internal bus width cannot accommodate a dynamic range higher than the dynamic range of the input data word.
Update June 2013
: the latest software for CONCERO enables 384kS/s mode! If you purchased a CONCERO at any time you can now upgrade your unit to 384kS/s. Check out the Software Updates for CONCERO
page. We now provide both a PC and a MAC version of the CONCERO updater. Please note that the 384kS/s is the new highest rate that the CONCERO can take from your USB source (352.8kS/s is the highest rate CONCERO HP and CONCERO HD can take), the internal filters still up-sample by a factor of four to the 176.4kS/s or 192kS/s rates.
Downloading and Installing
Both of our CONCERO products (CONCERO HD and CONCERO HP) are upgradeable via a USB connection to a computer. We offer upgrade utilities for both the Windows platform (XP, Vista, 7 and 8) and Mac OS X. Please follow the instructions below to download the appropriate updater (the updater differs for each model of CONCERO).
Step 1: Install pre-requisites
The CONCERO updater requires the .NET framework. The .NET framework is installed by default on all modern Windows installations. However, on Mac OS X platforms you will need to load the Mono framework. The mono framework can be installed from here: Mono Framework
Step 2: Download Installer
Please download the software that corresponds with your operating system:
Step 3: Unpackage Updater
Unzip the updater to a location of your choice.
Step 4: Perform Update
Run the CONCERO updater program while the CONCERO is plugged in via USB. The CONCERO updater requires the use of a USB 2.0 or USB 1.0 port to work properly. Once the updater has found your device you may follow the on-screen directions. Note: The updater computer will require an internet connection to retrieve the most up-to-date firmware for your device.
Step 5: Enjoy!
Enjoy the newly upgraded firmware on your CONCERO audio device! If you run into any issues while performing an upgrade, please try closing the updater, unplugging the CONCERO and then trying again.
Returning the CONCERO for Repair under Warranty
If you find any problems, faults or unexpected performance in the CONCERO unit in the first year of operation, it may well be covered by our warranty policy. The first step in returning a unit to Resonessence is to contact your local dealer, or directly by phone to us at our Canadian headquarters (778) 477-5536.
