External Connections External Connections The Lynx L22 includes two break-out cables that provide connections for external equipment. The L2Audio cable provides XLR connectors for analog audio signals. The L22Sync cable provides XLR connectors for digital audio signals and female BNC connectors for clock input and output.
External Connections Please note that with 16 dB of headroom, the Lynx L22’s analog outputs are capable of delivering +20 dBu signal levels. It is important to verify that the equipment you are driving is capable of handling these signal levels in order to prevent clipping or possible damage. Digital Audio The XLR connectors on the L22Sync Cable, labeled DIGITAL IN and DIGITAL OUT are used for AES/EBU and S/P DIF digital audio connections.
Using Your Lynx L22 Using Your Lynx L22 With the Lynx L22 and its drivers properly installed in your computer, you can begin to use its capabilities with any third party audio application running under Windows or ASIO compliant applications under Macintosh OS. In order for these applications to access the Lynx L22 you must select one of the Lynx L22 audio devices in an application’s configuration menu for audio or wave.
Using Your Lynx L22 Mixer Configuration Recall The state of the Mixer settings are saved each time Windows is shut down. The stored settings are automatically recalled the next time Windows is restarted. Clock Source Requirements A valid clock source signal must be connected to the appropriate Lynx L22 clock connector when the Sample Clock Source is set to either Digital, External, or Header. If a signal is not present, the sample clock generator will run very slowly or erratically.
Using Your LynxTWO Windows Quick Audio Test The installation of your Lynx L22 can be tested using the Lynx L22 Mixer and the Sound Recorder application that ships with Windows 98/ME and Windows NT/2000/ XP. Any other audio application capable of audio recording and playback can be used in a similar manner. 1. Connect a stereo analog signal source to the IN 1 and IN 2 connectors on the Audio cable. 2.
Mixer Reference Mixer Reference The Lynx L22 Mixer provides complete software control of the audio features of the Lynx L22 and an indication of signal level during recording and playback. This section describes the function of each menu and control of the mixer. Mixer Menu With one Lynx L22 installed in your computer the first selection in the Mixer Menu will be “Lynx L22 Mixer” proceeded by a check mark.
Mixer Reference Word256, Header/Word, or Header/Word256 the displayed sample rate must match the rate of the incoming clock being used for synchronization. This will ensure the correct sample rate is stored in the file’s WAV header, and that audio will playback at the correct sample rate. Digital Format – Allows selection of either AES/EBU or S/P DIF formats for Digital In and Digital Out. Digital Mode – Selects the mode for the Sample Rate Converter on the Digital Input. SRC On – Default.
Mixer Reference Recalibrate Converters – Used to calibrate DC offset of the A/D and D/A converters. When the Lynx L22 driver first loads, the converters are calibrated for optimum fidelity. Over time temperature changes inside your computer may cause the DC offset to drift slightly. Because of this, Lynx recommends recalibration 15 to 30 minutes after your computer has been turned on and whenever significant changes in room temperature occur.
Mixer Reference Record Window Record Source Selection – Provides selection for the source of each associated record channel. Each channel may take its source from any one of the 24 available inputs. Peak Meters – Displays the instantaneous level of the audio being sent to the Lynx L22. Mute – Provides a mute function for each associated input. Dither – Enables / Disables dither for each associated input. The Dither type is specified in the Adapter window.
Mixer Reference Outputs Window Overload Indicator – Provides instantaneous overload indication of the audio being played or monitored. Once an overload condition has occurred the overload indicator remains until reset manually by the user by clicking on the control. Peak Meters – Displays the instantaneous level of the audio being played or monitored. Volume Faders – Controls digital attenuation of the audio being played or monitored. This control acts on the digital signals before D/A conversion.
Working with Third Party Applications Working with Third Party Applications Compatibility The drivers included with your Lynx L22 provide compatibility with all standard third party audio editing applications that communicate with Windows Wave audio, DirectSound and ASIO devices. A list of applications that have been tested for compatibility is provided on the Lynx web site at http://www.lynxstudio.com/swlist.html.
Working with Third Party Applications The Lynx L22 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. The Lynx L22 Mixer application displays the currently selected bit depth for each device just above the device name in the Record window and the Play window.
Configuring Multiple LynxTWO’s Configuring Multiple Lynx L22’s More than one Lynx L22 card can be installed in a computer for additional audio channels. If required, all Lynx L22’s in a computer can be configured to maintain sample accurate synchronization during digital audio recording and playback. Cards are synchronized in a master-slave arrangement. One card is selected as the master which provides the word clock source for the other slave cards in the system.
Configuring Multiple LynxTWO’s 4. 5. Listen to the playback of any wave file and note which Lynx L22 card is generating the audio signal. In this case, the card generating audio is adapter 1. Repeat steps 3 and 4, for “Lynx L22 2 Play 1”, “Lynx L22 3 Play 1”, and so on until all Lynx L22’s in your system have been identified. The next step is to choose which Lynx L22 will act as a master.
Troubleshooting Troubleshooting When Windows starts I see a Lynx L22 Mixer error - “No mixer device drivers are available”. This error will appear when the Lynx L22 Mixer is loading during Windows startup and the Lynx L22 is not installed correctly. You should check the following items: 1. With the computer power off, verify that the card is properly seated in the PCI slot. 2. Verify the Lynx L22’s resources are not conflicting with some other device in your system.
Troubleshooting Audio playback sounds fast or slow when I am using the digital input as the clock source. When the digital input is selected as the clock source, the Lynx L22’s sample clock will run at the sample rate of the incoming digital input signal. In the case when the sample rate of this signal is 48 kHz and a file being played was actually recorded at 44.1 kHz, the audio will playback fast.
Troubleshooting Can the Lynx L22 share interrupts with other devices? The Lynx L22 is able to share interrupts with other PCI devices, as long as the other PCI device’s driver is written correctly to share interrupts. The Lynx L22 is not able to share interrupts with ISA devices (such as a modem, serial port, printer port, keyboard or mouse). The BIOS on many motherboards require the user to manually reserve an interrupt (IRQ) for an ISA device.
