    CONCERO HP is the Headphone driver version of CONCERO. It supports DSD64 and DSD128, Sample rates up to 352.8kS/s and 24bits. Over 100dB (0.001%) THD+Noise performance into headphones above 300 Ohms (over 90dB performance into 32 Ohm headphones). S/PDIF and USB Audio 2.0 data sources.

    CONCERO HP Uses the ES9018-2M – the latest chip from ESS Technology.

    CONCERO HP is three things in one: first, it is the Resonessence upgradable FPGA DSP core with all the proven filters and algorithms of the CONCERO family; second, it uses the 32bit ES9018-2M Sabre DAC in both PCM and DSD modes to provide high quality audio; and finally it provides a state-of-the-art headphone driver capability.

    The CONCERO HP delivers digital music directly from your computer USB or audio S/PDIF source to your chosen headphones with exceptionally low distortion (< 0.001%) and high dynamic range (> 112dB).

    Similarly to all the CONCERO family, the CONCERO HP enumerates on the PC as a USB Audio 2.0 device (by use of our freely provided Thesycon USB Audio 2.0 driver), and natively on the Mac. But in addition, CONCERO HP also enumerates as a Human Interface Device  (HID) which allows its volume control to drive the volume level in the music player directly. (Learn more about the volume control)

    When internal up-sampling is being used (taking your 44.1kS/s or 48kS/s to 176.4kS/s and 192kS/s) pressing the center of the volume control knob cycles through the Resonessence up-sampling filters for you to optimize your listening experience.

    ( These last two features mean that no remote control is necessary with the CONCERO HP, but if you prefer to use a remote control, CONCERO HP responds to the Apple IR Remote just like the other CONCERO family members.  )

    ( A configuration utility on both PC and MAC is provided to configure the CONCERO HP to use S/PDIF as either an input or as an output to enable S/PDIF bridge mode. This configuration utility is provided so that the CONCERO HP requires no remote control to access all the features. You can change the configuration as often as you like, the configuration you chose is stored in the CONCERO’s non-volatile memory chip. )

    Important note: the volume level that you set on the CONCERO HP is stored in your music application. Both the PC and MAC have the feature that the last setting of the volume is restored when you use your CONCERO HP for a second or subsequent time. However, the very first time that you use the CONCERO HP, both Window’s and the MAC OS will initially set the volume to 0dB – ie to the maximum level. Take care therefore when first using the CONCERO HP that you have the headphones unplugged and set the volume to a lower level before listening. This initial volume level of 0dB may also apply if you use a different USB port for your CONCERO HP. Our engineers suggest that certain software music players may store a different volume level for each USB port.

    CONCERO HP is designed to be the only audio device you need to take your library of digital music in whatever format you choose, to your high quality headphones. Laptop, CONCERO HP and quality headphones together make an outstanding audiophile system.

     

    • 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.

    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.

    CONCERO Mode Selection

    CONCERO is powered over USB.

    If CONCERO detects an active host on the USB connection

    then it enumerates  (that is, informs the host that it is an

    audio device and requests that the driver be connected)

    and enters ‘USB DAC’ mode. CONCERO and CONCERO HD

    enable the ‘USB to SPDIF Bridge’ concurrently.Normally, powered by an active host, CONCERO will

    output audio to both SPDIF out and Analog out at the same

    time. We expect that most of our customers will use one

    or other of the outputs. However, if you choose to use both

    outputs (perhaps directing Audio output to your headphone

    driver, and SPDIF output to your power amplifier) we provide

    a means to enable one or the other via the Apple IR Remote.

    (See below).The display LED will remain red until data begins to stream

    from the USB host, at which point the LED turns blue.SPDIF input mode may be selected while plugged into an

    active USB port by pressing the “up button” two times.

    If CONCERO does not detect an active host (that is, if it finds

    that it is plugged into a power-only USB) then

    CONCERO enters ‘SPDIF Dac’ mode.

    CONCERO and the Apple IR Remote

    CONCERO responds to the Apple IR Remote (without the need

    to ‘pair’ with it).

     

    Pressing the menu button cycles through the filter settings:

    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.* On the first menu press CONCERO engages the IIR

    up-sampling filter.* On the second menu press CONCERO engages the

    Apodizing up-sampling filter.Note that both filters up-convert 44.1kS/s and 48kS/s

    data to 4x rate. (ie to 176.4kS/s or 192kS/s).

    Data received at higher than 48kS/s is not filtered: it

    is processes bit-perfect. When either filter is active,

    the display LED will be magenta while music is playing.

    Learn more about Resonessence custom filters.

    IN USB DAC and USB SPDIF Bridge mode:

     

    Pressing the pause/play button pauses and plays by sending

    commands to the music player application.

    Pressing left/right scrolls in the application playlist.

    Pressing the UP/Down button enables or disables the Analog

    output and SPDIF output.* Initially both outputs are active.

    * Pressing the up button shuts off the SPDIF output.

    * Pressing the up button again selects SPDIF as input.

    * Pressing the down button shuts off the Analog output.The LED flashes briefly to indicate that the action has

    been taken. Upon reaching the top (SPDIF input selected)

    or bottom (SPDIF output only) the LED no longer flashes,

    indicating that you have reached the setting.

    CONCERO HP Configuration Tool

     

    Resonessence will provide a configuration tool on both

    MS WIndows and MAC OS to allow a non-volatile setting

    of the CONCERO HP for S/PDIF mode. Specifically, the

    user will be able to configure the S/PDIF port as an output

    that replicates the data received on the USB port (except

    for DSD128 mode), or operates as an input for the DAC.

    All Modes

    Low Jitter Oscillators for Reference clocks. (No PLL’s)

    Custom Async USB 2.0 up to 24bit 384kS/s (download Windows USB Audio 2.0 Driver)

    Selectable ‘bit-perfect’ mode of operation, jitter removed, but identical data

    Two selectable up-sampling filters: Minimum Phase IIR, and Apodizing

    High Quality Film Caps for Audio Section

    3 Dedicated regulators for Audio Section (2 in DAC chip, 1 on-board)

     

    USB DAC mode

    To use these two USB host modes, connect the USB of CONCERO to the USB

    Host (use a High Speed USB port, not a Full Speed USB port). Connect your

    analog input pre-amplifier to the analog output ports on CONCERO HD,

    – or – connect your SPDIF input pre-amplfier to the SPDIF output on

    CONCERO HD. On CONCERO HP connect the Headphone to the output socket,

    (ensure the volume level on your player application is not too high!)

     

    HD and HP Models: DSD64 and DSD128 using DoP protocol version 1.1

    Apple Remote IR sensor for USB HID Control. (Play/Pause, Prev/Next track)

    Data Lock indication with Blue LED illumination

     

    SPDIF DAC mode

    Please note: External USB based Charger is needed for power supply. To use

    this mode, connect the USB of CONCERO to a power-only USB port. (Such

    as are commonly used to charge cell phones). Because CONCERO will not find

    an active USB Host on such a connection, it will switch to SPDIF DAC mode.

    Connect your SPIDIF output from your digital music source to the SPDIF port on

    CONCERO, connect your analog input pre-amplifier to the analog output ports

    on CONCERO. Connect the headphones to the CONCERO HP.

    Any SPDIF data received will then be output to the analog outputs.

     

    SPDIF Input with up to 24bit 192kS/s support

    Galvanic Isolated SPDIF Input

    USB port is now the power supply, can use high end USB cable and “power-only” cable.
