    The figure below illustrates the connection of an eight-channel A/D converter and an eight-channel D/A converter to I/O Port A of the AES16e. This setup uses only half of the available I/O on the AES16e. Additional converters can be connected to I/O Port B to provide up to 16 channels of A/D and D/A conversion.
  • Page 27 Each of these ports provides eight channels of input and eight channels of output. In this setup, either the digital mixer or AES16e can act as the system clock master depending on the clock settings of each device. In each case, the clock is transmitted to the receiving device via the AES/EBU connection.

  • Page 38: Adapter Window

    Windows Sample Clock Section This section of the mixer provides control of the system sample clock generator. All AES16e audio devices on a single card MUST have identical sample rates since there is one on-board generator. Sample rates cannot be changed while AES16e is playing or recording – unless the “Allow Clock Change if Active”...
  • Page 39 “Internal”. The rate will change only if the card is idle (not recording and playing). Manual adjustments are not required if the card is being used with an application. This control is primarily useful when the AES16e is the clock master for other digital devices.
  • Page 40 1. The selected source is not present or the connected device is not generating a valid clock signal. This can be confirmed by seeing “Not Present” next to this source. In these cases, the AES16e will operate from its Internal clock until a valid clock signal is connected to the selected clock source.
  • Page 41 Lynx Mixer Reference 3. The Clock Source was selected when the AES16e card was being accessed by some software application. In this case, the Preferred Clock Source will become the Current Source when the card is no longer being accessed. If “Allow Clock Change if Active” is selected from the Lynx Mixer Settings >...
  • Page 42 When DualWire In is checked to enable AES dual-wire operation on input, Clock Rate should read half of the encoded channel status rate described above. For example, when running at 192 kHz with dual-wire inputs, the Clock Rate should indicate 96.0 kHz and the Current Rate should indicate 192 kHz. AES16e User Manual Page 42...
  • Page 43 For example, when the device connected to Digital In 5 is running at 48 kHz, the AES16e-SRC is running at 44.1 kHz, and SRC Enable for Digital In 5 is ON, the AES16e-SRC will convert the sample rate from 48 kHz to 44.1 kHz and the SRC Ratio (see below) will indicate approximately 0.918:1.

  • Page 44: Record/Play Window

    In this example, LStream In 1 is being routed to the left channel of record device 1. This input would be valid if an LS-ADAT ADAT card was connected to the AES16e’s LStream Port.
  • Page 45 Lynx Mixer Reference Peak Meter These meters display the instantaneous peak level of audio being sent to the AES16e input selected by the Input Source Select buttons.

As discussed in Section 5.1.5 Digital Mixer Outputs, each output of the AES16e is derived from a ten-input submixer. This submixer is shown below. The inputs to the submixers include both input signals and playback signals.
  • Page 57 AES16e’s on- board digital mixer. Instead of using the Lynx Mixer to manually enable monitoring as discussed in the previous section, controls within the application provide convenient access to this functionality.

  • Page 58: Playback Routing And Mixing

    Click the speaker icon in Samplitude/Sequoia to enable Direct Monitoring. Playback Routing and Mixing In addition to standard monitoring of inputs through physical outputs, the Lynx mixer is capable of sophisticated routing and mixing of playback and record sources. One can monitor playback from several applications through a single output, combine live input and playback streams, and record a single source into several applications with the power of this flexible tool.

  • Page 59: Clock Selection And Control

    Operating System will resample the playback stream to match the current sample rate of the AES16e. In this case the audio speed and pitch will be fine, but there may be undesirable consequences from this low-quality sample rate conversion.

  • Page 60: Asio Specific Setup (Windows Only)

    Several control parameters of the AES16e are accessible from the ASIO Control Panel within applications that utilize the AES16e ASIO driver. One of the benefits offered by this inter-application control, is that these parameters can be saved with a project – allowing consistent performance conditions each time a project is opened.

  • Page 61: Controlling Latency By Changing Buffer Size

    Lynx LS-ADAT card would need to be used in conjunction with the AES16e in order to provide a sync source to the system. With a valid sync source connected to the ADAT Sync In port on the LS-ADAT, sample-accurate synchronization is possible via APP.

  • Page 62: Working With Third Party Applications

    When more than one AES16e is installed in your system, the device names will contain a numeric adapter ID assigned by the operating system. For example, the first input device on adapter 2 would be listed as “AES16e 2 Record 1”. Refer to the “Configuring Multiple AES16e’s” in section 9 for more information.

  • Page 63: Controlling Audio Bit Depth

    The application uses this information to set the resolution of the AES16e. The AES16e supports file types with 8, 16, 24, or 32 bit word widths. Note that 32-bit files contain 24-bit data with zero data in the least significant bit positions.
