  • Page 20: Lynx Mixer Application Reference

    The Lynx Mixer is a single screen app for controlling the routing and various features of the E22/E44. The software simply reveals and facilitates changes to the hardware, so the Mixer will not launch if a Lynx card is not installed and functional. In addition to the controls on the Main Window there are two menus with additional features.

  • Page 21: Navigation Bar

    software applications (the exception being non-ASIO software under Windows: see Section 8.1.4: Configure for use). Most features are identical for the OS-X and Windows versions, but there are a few OS- specific controls. These will be pointed out as such in the sections below. 7.3.1 Navigation Bar The bar at the top of the Lynx Mixer main window, provides access to commonly used functions, and allows for customizing the displayed elements.
  • Page 22 Rate Select This button displays the current sample rate of the Lynx card and can also be used to select a desired sample rate when the card is operating off of its Internal Clock. However, when on Internal clock, the sample rate is generally determined by the audio application being used, or the default sample rate settings in the operating system.

  • Page 23: Adapter Section

    This button can turn the SynchroLock clocking system On and Off. SynchroLock is Lynx’s proprietary technology for attenuating jitter on clock inputs and providing a stable clock for all digital signals passed through the E44/E22. This button also shows the status of the SynchroLock clocking system. Prior to achieving lock, the four green LED’s give an indication of the completion of various lock stages.
  • Page 24 Disabled: Indicates that SynchroLock has been manually turned Off. Preferred Clock Source This section of the mixer provides control of the system sample clock generator. All E22/E44 play and record devices on a single card MUST have identical sample rates since there is one on-board generator.

  • Page 25: Record Section

    Input and output trims can be set independently for any pair of channels. The E44 card will display trims for all four inputs and outputs, the E22 will show them for two ins and outs. For details about setting input and output levels with the onboard Trim Pots, see Section 8.3: Onboard Variable Trim...
  • Page 26 Digital Inputs instead of Analog, so that they appear first in the list. For an E44 user, it may be advantageous to have the Analog and Digital inputs appear in contiguous pairs, rather than the default arrangement of the four Analogs First and then the four Digitals.
  • Page 27 into an audio application. It is applicable to Monitoring Level only (how loud that signal source is through the output you are listening to). Faders and Meters The METERS on the Input section show the peak level of the signals at the associated input. Since there is no way to attenuate the level of the signal being recorded (except for the rotary Trim controls, see Section 8.3: Onboard Variable Trim...

    Monitoring levels, pan or balance, mirroring of streams, and muting can be easily set here. With an E44 there will be four pairs of faders here; with an E22, two pairs. This section can be “hidden” by clicking the PLAY button in the Lynx Mixer Toolbar. When the section is hidden, all of the settings are still active.
  • Page 29 Play channels are pre-routed by default. Play 1+2 is routed Analog Output 1+2, Play 3+4 is routed to Analog Output 3+4 on an E44, and Digital Out Left/Right with an E22. With an E44, play 5-8 are assigned to the Digital Outputs For most users, the default is appropriate and will never need to be changed.

  • Page 30: Outputs Section

    The channels shown will be appropriate to the card used. There will be 8 output channels for an E44 (4 analog and 4 digital), and there will be 4 channels for an E22 (2 analog and 2 digital).
  • Page 31 In the Mixer’s default state, each output has a play device routed to it. Play 1+2 is routed to Analog Output 1+2, Play 3+4 is routed to Analog Output 3+4 on an E44, and Digital Out Left/Right with an E22. With an E44, play 5-8 are assigned to the Digital Outputs.

  • Page 35 Allow Clock Change If Active This option allows the Current Clock Source to be changed even when the Lynx card is being used by an audio application. Please note: there will be an audible glitch when a clock source is changed during playback or recording of audio. With the Allow Clock Change if Active option OFF (the default), changing the Preferred Clock Source will not change the Current Clock Source until the driver is no longer being utilized by a software application.

  • Page 36: Using The E22/E44

    8 Using the E22/E44 With the E22/E44 correctly installed in your computer, you can begin to use it with most popular third-party audio applications. In this section we will explore setting up the card for different contexts of use. Configuring multiple cards Up to four PCIe Lynx cards can be used in a single computer.

  • Page 37: Setting Device Order

    In these cases, the Lynx Cards can either slave to their word clock inputs or digital inputs. On the E22 and E44 cards, the digital I/O and word clock connectors are on the same cable set.
