External Connections

The LynxTWO includes two break-out cables that provide connections for external equipment. The L2Audio cable provides XLR connectors for analog audio signals. The L2Sync cable provides XLR connectors for digital audio signals and female BNC connectors for clock input and output.

Two bracket mounted D-connectors provide connection ports for the break-out cables: the L2Audio Port is a 25-pin female D-connector and the L2Sync port is a high-density 15-pin female D-connector.

Referring to figure above, locate the L2Audio Port and the L2Sync Port on the mounting bracket of the LynxTWO. Insert the L2Audio cable into the L2Audio Port and tighten the thumb screws on the cable shell. Insert the L2Sync cable into the L2Sync Port and tighten the thumb screws on the cable shell.

Use of both cables is not a requirement. If you will be using only the analog audio capabilities of the LynxTWO, for example, there is no reason to connect the L2Sync cable.

Analog Audio

For the LynxTWO A Model, the XLR connectors on the Audio Cable, labeled IN 1, IN 2, IN 3, IN 4, OUT 1, OUT 2, OUT 3 and OUT 4 are used to connect balanced and unbalanced analog equipment to the analog inputs and outputs of the LynxTWO. The LynxTWO B Model replaces IN 3 and IN 4 with OUT 5 and OUT 6. The LynxTWO C Model replaces OUT 3 and OUT 4 with IN 5 and IN 6. Make connections to professional consoles and other balanced equipment directly with these connectors. Connect to balanced equipment with 14 TRS jacks using XLR-to-TRS adapters such as the Lynx CBL-XF2TM18 (female XLR) and the Lynx CBL-XM2TM18 (male XLR). Connect to unbalanced consumer devices with RCA jacks using XLR-to-RCA adapters such as the Lynx CBL-XF2RM18 (female XLR) and the Lynx CBL-XM2RM18 (male XLR). Adapters with line transformers are not required. Refer to the “XLR Connector Wiring and Adapters” section for information regarding XLR adapter construction.

The nominal analog signal levels are compatible with either professional or consumer equipment. Use the Trim controls on the LynxTWO Mixer application to select +4dBu for balanced professional devices or -10dBV for balanced or unbalanced consumer devices.

Please note that with 16 dB of headroom, the LynxTWO'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 L2Sync Cable, labeled DIGITAL IN and DIGITAL OUT are used for AES/EBU and S/P DIF digital audio connections. Connect AES/EBU devices directly and select AES/EBU Digital Format in the LynxTWO mixer application. Connect to S/P DIF devices using the supplied XLR-to-RCA adapters. Select S/P DIF Digital Format in the LynxTWO mixer application.

LTC Connections

Two BNC connectors on the L2Sync Cable, labeled LTC IN and LTC OUT are used to connect to the LynxTWO's LTC reader and generator.

Sync Input and Clock Output Connectors

Two BNC connectors on the L2Sync Cable, labeled SYNC IN and CLOCK OUT are used to synchronize the LynxTWO with external equipment. The connectors support TTL or Composite Video level signals and should be connected with 75-ohm coaxial cable. Connect the SYNC IN connector to the clock output or video output of an external device and select External as the Sample Clock Source in the LynxTWO mixer. Adjust the clock Reference to match the incoming clock type.

CLOCK OUT is a word clock that tracks the sample rate of the LynxTWO. Connect this output to the word clock input of an external device.

Header Connectors

The Header connectors labeled CLOCK IN and CLOCK OUT are used to synchronize the LynxTWO with equipment located inside your computer. For systems containing multiple LynxTWO's, these connectors are utilized to synchronize the sample clocks of each card. The connectors support TTL level signals and should be connected using the Lynx Internal Clock Cable, Lynx Universal Clock Cable or similar 75-ohm coaxial cable.

Connect the CLOCK IN connector to the clock output of an internal device and select Header as the clock source in the LynxTWO mixer. Adjust the clock Reference to match the incoming clock type.

The signal on the CLOCK OUT header is a word clock that tracks the sample rate of the LynxTWO. Connect this output to the word clock input of an internal device or another LynxTWO.

Using Your LynxTWO

With the LynxTWO 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 LynxTWO you must select one of the LynxTWO audio devices in an application's configuration menu for audio or wave. Refer to the “Working with Third Party Applications” section for more information regarding device selection.

Prior to audio recording or playback, you should also use the LynxTWO Mixer application to adjust the Trim and Digital Format to match the equipment connected to your LynxTWO. Failure to do so may result in improper operation or damage to external equipment.

The LynxTWO Mixer

The LynxTWO Mixer, which is installed during setup, provides software control of the features of the LynxTWO and a visual indication of audio signal level during recording and playback.

It can be used dynamically to change operational settings of the LynxTWO, but in most cases once the settings are configured for a particular studio installation they require no adjustment.

Starting the Mixer

After installation, the LynxTWO Mixer icon will appear on the Windows task bar in the lower right corner of your screen. By double clicking on this icon with your left mouse button, the LynxTWO Mixer will launch. Alternatively, a single click with your right mouse button on this icon will open a menu that provides access to basic mixer controls and an “Open Mixer” selection that will also start the mixer.

If the icon does not appear on the Windows task bar, the LynxTWO mixer can be started by selecting Start > Programs > Lynx Studio Technology > Mixer.

General Operation

If you are simply recording and playing digital audio without synchronizing to an external clock source, you can begin using the LynxTWO by simply setting the analog Trim level and/or the Digital Format if required. Input monitoring can be enabled by selecting the desired Monitor Source and then clicking the Monitor buttons on the Analog and/or Digital Out panels.

Typically, it is convenient to keep the Mixer running on your Windows desktop to monitor signal levels or to allow instant access to Mixer controls requiring dynamic changes. The Mixer can be forced to appear on top of other applications by selecting the “Always On Top” option in the Settings pull-down menu.

For further information about the LynxTWO Mixer controls refer to the “LynxTWO Mixer Reference” section for a complete description.

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 LynxTWO 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. Symptoms of this problem include audio files that sound either fast, slow or garbled.

When a valid clock source is present, the frequency and type of clock signal must match the Sample Clock Reference setting selected in the Mixer. The frequency of word clock sources, chosen by setting the Sample Clock Source/Reference to either Digital/Auto, External/Word, or Header/Word, must match the sample rate specified when recording new files or the sample rate associated with a previously recorded file during playback. For example, if a 44.1 kHz word clock is connected to the external clock input, the Sample Clock Source/Reference must be set to External/Word and the sample rate must be set to 44.1 kHz when a new file is being recorded in an application. Failure to do so will result in files being recorded at the wrong sample rate.

Volume Faders and Signal Quality

The faders in the LynxTWO Mixer perform digital attenuation on audio signals in the digital domain. The attenuation is applied to the digitized signals just prior to the D/A converters.

As with any digital signal processing function, the digital attenuation calculations used by the LynxTWO can introduce arithmetic errors that can add small amounts of noise to signals. To insure the highest signal quality it is highly recommended that the faders be left in their maximum position during critical recording and playback. In this position, no attenuation calculations are performed.

Mono Recording and Playback Operation

When recording a file in mono, the LynxTWO will provide an audio signal from the left channel only. The audio signal from right channel is not used. When playing back a file in mono, the LynxTWO will send the signal to both the left and right outputs. To force playback on a single output, turn up the volume for the desired output, and turn down the volume for the output to be muted.

Windows Quick Audio Test

The installation of your LynxTWO can be tested using the LynxTWO Mixer and the Sound Recorder application that ships with Windows 95/98/ME and Windows NT/2000. 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. Connect the OUT 1 and OUT 2 connectors to an amplifier or mixer capable of delivering an audio signal for listening via headphones or speakers.

3. Open the LynxTWO Mixer by double clicking on the mixer icon.

4. In the LynxTWO Mixer, set the Trim to either +4 dBu or -10 dBV to match the signal level of the connected equipment.

5. In the LynxTWO Mixer Record Panel, route the Record 1 Left & Right signal from the Analog In 1 & 2 to the Analog Out 1 & 2. This is done by pressing the “1” button for Record 1 Left and pressing the “2” button for Record 1 Right. Unmute the Monitor Mute buttons for both the left and right channels. You should hear the signal from the audio source which is connected to the analog inputs. If this is not the case, check your connections.

6. Disable input monitoring by again clicking on the Mute buttons on the Record 1 device. After doing so, the buttons should look like they are in the “out” or non-depressed position.

7. Start Sound Recorder by clicking Start > Programs > Accessories > Multimedia > Sound Recorder. Position Sound Recorder on your screen so it be easily viewed along with the LynxTWO Mixer.

8. In Sound Recorder, select the LynxTWO's audio devices by opening the Edit menu and selecting Audio Properties. Select LynxTWO Play 1 as the Preferred device for playback and LynxTWO Record 1 as the Preferred device for recording.

9. Record a short sample by clicking the red record button followed by the stop button in Sound Recorder. During recording, you should observe a graphic display of the waveform being recorded in the center display in Sound Recorder. You should also see activity on the Record 1 peak meters of the LynxTWO Mixer.

10. Playback the test sample by clicking the play button in Sound Recorder. During playback, you should observe a graphic display of the waveform being played in Sound Recorder. You should also hear the recorded audio and see activity on the Analog Out peak meters of the LynxTWO Mixer.

If the test did not operate as described or you received any errors, please refer to the “Troubleshooting” section of this manual.

Mixer Menu

With one LynxTWO installed in your computer the first selection in the Mixer Menu will be “LynxTWO Mixer” proceeded by a check mark. With more than one LynxTWO installed in your computer, the Mixer Menu will list each LynxTWO with a numeric suffix, and allow you to select which card is being controlled by the Mixer application. A check mark will appear next to the currently selected LynxTWO. Refer to the section on “Configuring Multiple LynxTWO’s” for a more information regarding the use of multiple cards.

Adapter Window

Sample Clock – This section of the LynxTWO mixer provides control of the sample clock source and reference. Since the sample clock is the master timing source, all LynxTWO audio devices on a single card must have identical sample rates. Sample clock settings cannot be changed if any LynxTWO audio device is playing or recording.

Source - Allows selection of the sample clock source from one of the following:

Internal - Clock derived from the on-board crystal oscillator.

Digital – Clock signal from the DIGITAL IN connector on the L2Sync cable. The Digital Format control must be correctly selected when selecting this clock source.

External - Clock signal from the SYNC IN connector on the L2Sync cable.

Header - Clock signal from the board-mounted CLOCK IN header.

Video – NTSC or PAL composite video signal from the SYNC IN connector on the L2Sync cable.

LStream 1 – Clock signal from the LStream port on the L2Sync connector.

LStream 2 – Clock signal from the LStream port on the board mounted header.

Reference – Provides selection of the clock source reference type from one of the following:

Auto - Automatic selection. Valid for Internal and Digital clock sources.

13.5MHz - 13.5MHz video dot clock. Valid for External and Header clock sources.

27MHz - 27MHz video dot clock. Valid for External and Header clock sources.

Word - Word clock. Valid for External and Header clock sources.

Word256 - 256 times word clock. Valid for External and Header clock sources.

Rate – Displays the current sample clock rate of the LynxTWO. When the Sample Clock Source/Reference are set to Digital/Auto, External/Word, External/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. The sample rate converter is on.

SRC Off: Clock Synchronous – Turns off the sample rate converter and indicates that the digital input and digital output clocks are synchronous. This mode is useful when the digital output is feeding the digital input either directly or through an external device with no sample rate converter.

SRC Off – The sample rate converter is off. When in this mode the Sample Clock Source must be set to Digital. Use this mode when recording non-audio formats such as Dolby Digital, DTS or others formats that require bit-perfect transfers.

SRC On: Digital Out – The sample rate converter is turned on, but it is used by the Digital Output instead of the Digital Input. The Digital Input sample rate will determine the actual rate of the Digital Output. This mode is useful when sending audio to external equipment at a different rate than it was recorded.

Transmit Only – Disables the Digital Input and the sample rate converter. Used for testing purposes only.

Digital Input Status – Displays real-time status of the digital input, updated 4 times a second.

Digital In Rate - Displays the measured rate of the incoming digital signal.

SRC Ratio - Indicates the sample rate conversion ratio in SRC On mode.

Frame Rate - Indicates the actual frame rate of the LTC Receiver.

Position - Indicates the last frame position decoded from the LTC Receiver.

LTC Output - This section of the LynxTWO Mixer provides control of the Longitudinal Timecode generator.

Enable - When checked, the LTC generator is enabled.

Frame Rate – Provides selection of the frame rate of the LTC generator. Allowed rates are 24, 25, 29.97 and 30 fps.

Drop Frame - Used to indicate drop frame for 29.97 and 30 fps frame rates.

Sync Source – Selects the synchronization source the the LTC generator.

Position - Used to enter the starting position for the LTC generator and display the current timecode position when the generator is enabled.

Recalibrate Converters – Used to calibrate DC offset of the A/D and D/A converters. When the LynxTWO 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.

Dither Type – Provides selection of the type of dither used on all record channels. The selection may be one of the following:

None - Dither is disabled. Volume processing utilizes rounding prior to truncation.

Triangular - Enables the addition of triangular probability density dither. This type of dither is free of data-dependent noise modulation effects, but decreases signal-to-noise ratio by 4.8 dB. Triangular is the preferred dither type in most cases.

Shaped Triangular - Enables the addition of shaped triangular probability density dither. This type of dither is essentially a high-pass filtered triangular dither that places most of the dither energy at higher frequencies making it less audible to the human ear. Shaped triangular dither also decreases signal-to-noise ratio by 4.8 dB.

Rectangular - Enables the addition of rectangular probability density dither. This type of dither decreases the signal-to-noise ratio by 3 dB (less than triangular), but is less desirable because of its noise modulation effects.

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 LynxTWO.

Mute - Provides a mute function for each associated input.

Activity Indicators – The names at the bottom of the Record and Play windows reflect the name of its associated wave device. When a device is inactive its name is shown as blue text. When a device is active (currently open for play or record) its name appears in red text.

Play Window

Output Selection – Provides buttons for routing play device channels to output channels. Each button represents a physical output on the LynxTWO.

Volume Faders - Controls digital attenuation of the audio being played.

Mute - Provides a mute function for each associated play device channel.

Phase - Inverts the phase for each associated play device channel.

Device Format - Displays the bit-depth and number channels in use on this device. This is set by the audio application using each play device and is provided for reference purposes only.

Activity Indicators – The names at the bottom of the Record and Play windows reflect the name of its associated wave device. When a device is inactive its name is shown as blue text.

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. With the volume fader at its maximum position, the vertical line within the fader turns black, no volume calculation is performed and the audio stream is unaltered. This is the recommended position for critical recording and mixdown sessions in which the highest signal quality is required. Volume control processing is done prior to peak meter readings causing the peak meters to reflect any volume control changes. Since volume changes act on the digitally converted signals, they have no effect on the analog full-scale input and output levels. This must be done with the Trim control. When the volume fader is not at its maximum or minimum position, the vertical line within the fader turns red to indicate that the volume control is active.

Mute - Provides a mute function for each associated output.

Phase - Inverts the phase for each associated output. This is a master control and overrides the phase controls for any record monitor or play channel assigned to this output.

Dither - When pressed, enables the addition of triangular probability density dither for each associated output.

Working with Third Party Applications

Compatibility

The drivers included with your LynxTWO 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.

LynxTWO Devices

Third party applications communicate with the LynxTWO through its installed driver. The driver presents the LynxTWO's audio capabilities to applications as standard multimedia, DirectSound or ASIO devices.

Most, if not all, third party applications provide device selection in configuration, options, or preference setting windows or menus. For two channel or stereo audio applications, a separate selection option is typically provided for the input or recording device and the output or playback device. Multitrack applications provide multiple input and output device selection menus or windows. Refer to the documentation included with your application to determine how to select audio devices.

With the LynxTWO properly installed in your computer, the digital audio devices will be available to applications, and their names will appear in their device selection menus as follows:

LynxTWO Record 1 LynxTWO Play 1

LynxTWO Record 2 LynxTWO Play 2

LynxTWO Record 3 LynxTWO Play 3

LynxTWO Record 4 LynxTWO Play 4

LynxTWO Record 5 LynxTWO Play 5

LynxTWO Record 6 LynxTWO Play 6

LynxTWO Record 7 LynxTWO Play 7

LynxTWO Record 8 LynxTWO Play 8

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

Controlling Audio Bit Depth

Creating a audio file with a particular bit depth (or resolution) is controlled through an application's recording settings. These settings are typically adjusted in an audio device configuration menu or in a recording setup window just prior to recording. When recording is initiated the LynxTWO will generate audio samples of the desired resolution.

Bit depth control during playback of an audio file is also an application issue. When a file is played, the recorded bit depth is read from the file's header by the application. The application uses this information to set the resolution of the LynxTWO.

The LynxTWO 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 LynxTWO Mixer application displays the currently selected bit depth for each device just above the device name in the Record window and the Play window.

Simultaneous Device and Multitrack Operation

The sixteen audio devices of the LynxTWO operate completely independent in terms of whether they are in recording or playback modes and their associated audio files. This implies that the devices can operate simultaneously and support the so-called “full-duplex” mode where, for instance, the LynxTWO Record 1 device is recording while the LynxTWO Play 1 device is playing.

Although the devices act independently, when multiple devices are being used to record or play multiple audio files simultaneously, the LynxTWO driver has the capability to synchronously start all devices with sample accuracy. This is especially important for maintaining synchronization during playback of multiple devices and overdubbing.

By using all of the record and play devices, sixteen track recording and playback is possible. Again, control of this multi-channel operation is simply a matter of device selection in any compatible multitrack audio application.

Configuring Multiple LynxTWO's

More than one LynxTWO card can be installed in a computer for additional audio channels. If required, all LynxTWO'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. From the master, the word clock signal is daisy-chained from one slave to the next.

Word clock signals can be connected internally using the Internal Clock Cable, which is available from Lynx. The CLOCK OUT header of one card is connected to the CLOCK IN header of the next card. A separate cable is required for each slave card in the system.

Alternatively, the SYNC IN and CLOCK OUT connectors on the L2Sync cable can be connected externally with a standard 75 ohm BNC cable.

Adapter ID's in a Multiple Card System

When multiple LynxTWO cards are installed in a computer they are automatically assigned unique adapter ID numbers. These adapter ID's provide a means to identify and communicate with each LynxTWO when using the LynxTWO Mixer application and to select audio devices in third party applications.

In the LynxTWO Mixer, the adapter that a user wishes to control is selected from the Mixer pull-down menu. In a system with four LynxTWO's the adapters will be listed as follows:

LynxTWO 1 Mixer LynxTWO 2 Mixer LynxTWO 3 Mixer LynxTWO 4 Mixer

In each case, the adapter ID is the numeric character in each selection.

Most third party applications provide a setup or configuration menu for selecting a desired wave audio device for recording and playback. With multiple LynxTWO's in a system, each device name will contain the adapter ID. For example, the first play device on adapter 2 would be listed as “LynxTWO 2 Play 1”.

Selection of Master and Slave Clocks

In order to select master and slave LynxTWO's in a system, each adapter ID must be first physically associated with a LynxTWO installed in a computer slot. Since ID assignment is automatic, determining this association is somewhat trial and error. The procedure is as follows:

1. Connect at least one analog output channel of each LynxTWO to an amplifier, mixing console or other equipment that will provide audio monitoring.
2. Choose an audio application that allows selection of wave audio devices for audio playback.

3. Select "LynxTWO 1 Play 1" as the playback device.

4. Listen to the playback of any wave file and note which LynxTWO card is generating the audio signal. In this case, the card generating audio is adapter 1.

5. Repeat steps 3 and 4, for “LynxTWO 2 Play 1”, “LynxTWO 3 Play 1”, and so on until all LynxTWO’s in your system have been identified.

The next step is to choose which LynxTWO will act as a master. This choice is based on preference only, but for ease of connection it makes sense to choose a LynxTWO that is on one end of the PCI slot array on your motherboard.

Cable Connections

Starting with the master LynxTWO, insert the plug on one end of a Lynx Internal Clock Cable into the CLOCK OUT header, until it clicks and locks into place. This header is polarized to ensure the correct orientation of the cable plug. Insert the plug on the free end of the cable into the CLOCK IN header, on the nearest slave LynxTWO. Connect each slave in a similar manner. Refer to the figure below.

Alternatively, if clock connections are made externally using the SYNC IN and CLOCK OUT connectors on the L2Sync cable, use BNC cables to make connections between cards in the same sequence as described above.

Mixer Settings

With the clock connections in place, the sample clock settings of each LynxTWO must be adjusted using the LynxTWO Mixer.

For the master LynxTWO:

1. Select the master LynxTWO from the Mixer pull-down menu.
2. Select a desired Sample Clock Source.
3. Select a desired Sample Clock Reference.

For each slave LynxTWO:

1. Select the slave LynxTWO from the Mixer pull-down menu.
2. Set the Sample Clock Source to Header if internal clock connections are used or External if external clock connections are used.
3. Set the Sample Clock Reference to Word.

Troubleshooting

When Windows starts I see a LynxTWO Mixer error - "No mixer device drivers are available".

This error will appear when the LynxTWO Mixer is loading during Windows startup and the LynxTWO 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 LynxTWO's resources are not conflicting with some other device in your system. For Windows 95/98, check in the Device Manager (Start > Control Panel > System > Device Manager > Sound, video and game controllers > LynxTWO > Resources) to verify there are no resource conflicts. For Windows NT check in Windows NT Diagnostics (Start > Programs Administrative Tools > Windows NT Diagnostics > Resources) to verify there are no resource conflicts. If there is a resource conflict, you may need to move the LynxTWO to a different slot in your computer as some motherboards have specific resources assigned to specific slots, or change the interrupt setting in the BIOS setup screen. Please refer to your motherboard/computer documentation to determine how to change the interrupt for a PCI device.

I installed the LynxTWO in the PCI slot before I ran Setup.exe for Windows 95/98, what do I do now?

The device manager in Windows 95/98 requires the .INF file for a device to be installed before the Plug and Play scan to detect new hardware (which happens on each boot). This is why Setup.exe should generally be run before you install the LynxTWO into your computer. To correct this follow the steps listed here:

1. Load the device manager by clicking on Start > Control Panel > System > Device Manager.
2. There should be an entry called “+ ? Other Devices” listed about 3/4 down the page. Click on the + sign. “PCI Multimedia Audio Device” should appear.
3. Click on "PCI Multimedia Audio Device", then click on "Remove".
4. A "Confirm Device Removal" dialog box should appear, click on "OK". It might take a couple of seconds for this dialog box to close.
5. Click on "Refresh". After several seconds, a "New Hardware Found" dialog box will appear. Depending on your installation of Windows 95/98, another dialog box may appear asking for setup disk. The location you need to specify is: C:\Windows\System Click on "OK" after entering this path.
6. You may need to reboot your machine once this completes to get everything running properly.

Audio playback sounds really slow or erratic.

The Sample Clock Source selected in the LynxTWO Mixer is not connected to an active clock source. In this case, the sample clock generator on the LynxTWO runs very slow or erratic. This will occur if Digital is selected as the Sample Clock Source and there is either no connection to the LynxTWO's digital input or the device connected is turned off. The same situation will occur if either External or Header is selected as the clock source and there is no connection to the corresponding inputs on the card.

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 LynxTWO'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. To solve this problem either change the sample rate of the device driving the digital input or select Internal as the sample clock source using the LynxTWO mixer.

How do I minimize record monitor latency when I am doing overdubs?

Use the LynxTWO's on-board monitor circuitry. This is controlled by the LynxTWO mixer.

What does the green LED on the LynxTWO indicate?

When lit, the LED indicates successful initialization of the LynxTWO and the driver.

When I connect the LynxTWO analog outputs to the MIC inputs on my Mackie mixer I hear distortion.

The MIC inputs are being overdriven. Even with the mic gain adjusted to its lowest setting, the maximum signal level that the MIC inputs of the smaller Mackie mixers can handle is +14 dBu. In the +4 dBu trim setting, the LynxTWO is capable of delivering a +20 dBu signal. To solve this problem use 1/4" line inputs of the mixer. This requires the use of XLR to TRS adapters as described in the "External Connections" section.

I connect my microphone directly to the LynxTWO Analog Input connectors, but the level is very low, what is going on?

The LynxTWO Analog Input connectors should be connected line level devices only. To record from a microphone, first route the signal through a microphone pre-amplifier or mixer and then into the LynxTWO.

Where on the LynxTWO do I connect my internal CD-ROM drive?

The LynxTWO has no connector for an internal CD-ROM drive. We recommend using digital audio extraction software to capture the audio data from your CD's and saving it to your hard disk drive as .WAV files. Using this method, the audio files can be played back using the D/A converters on the LynxTWO which have far superior performance to those found in most CD-ROM drives. If your CD-ROM/DVD drive can reliably extract digital audio then you could use Windows Media Player (Version 7 or higher) to extract digital audio from CDs and play it in real-time with no physical connection between the LynxTWO and the CD-ROM drive.

Can I leave my current sound card in my computer while using the LynxTWO?

You may leave your existing sound card in your computer as long as you have a free PCI slot and interrupt for the LynxTWO. You may need to reconfigure certain software to access the LynxTWO instead of your existing sound card. Please refer to the “Working with Third Party Applications” section for details.

Can the LynxTWO share interrupts with other devices?

The LynxTWO 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 LynxTWO 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. If this is not done the BIOS may assign an ISA device and a PCI device the same interrupt which results in a conflict.

Does the LynxTWO support Dolby® AC-3 (Dolby Digital) and DTS?

The LynxTWO supports Dolby AC-3 and DTS through its Digital In and Digital Out ports. This allows an application to record an incoming Dolby or DTS encoded audio stream, as well as play an encoded stream through an external decoder. This ability is available for both S/P DIF and AES/EBU modes. The LynxTWO is able to recognize and generate the "Non-Audio" bit while recording for both S/P DIF and AES/EBU.

Is it safe to connect the LynxTWO analog outputs to a mixer whose inputs provide "phantom" power?

The LynxTWO should never have phantom power applied to it's output. This can easily be avoided by connecting the LynxTWO to the line inputs in your mixer, and not the microphone inputs. Generally, lower cost mixers have line inputs on TRS connectors. If you use XLR to TRS adapters cables you should be able to connect the LynxTWO to your mixer and avoid any phantom powering problems.

XLR Connector Wiring and Adapters

This section describes the proper wiring of cables that can be used to adapt both the analog and digital audio XLR connectors on the LynxTWO Audio Cable.

Balanced Connections

The wiring method for balanced connections with XLR connectors to balanced TRS ( 14 ” phone) connectors using shielded twisted pair cable (2 wire + shield) is as follows:

XLR Pin 1 (GND) to cable shield and to the TRS sleeve

XLR Pin 2 (+) to one signal wire and to the TRS tip

XLR Pin 3 (-) to the other signal wire and to the TRS ring

Unbalanced Connections with Twisted Pair Cable

The wiring method for unbalanced connections with XLR connectors to 14 " phone connectors (tip and sleeve only) using shielded twisted pair cable (2 wire + shield) is as follows:

XLR Pin 1 (GND) to cable shield with no connection on the other end

XLR Pin 2 (+) to signal wire and to the 1/4" phone tip

XLR Pin 3 (-) to the other signal wire and to the 1/4" phone sleeve

The wiring method for unbalanced connections with XLR connectors to RCA/Phono phone connectors using shielded twisted pair cable (2 wire + shield) is as follows:

XLR Pin 1 (GND) to cable shield with no connection on the other end XLR Pin 2 (+) to signal wire and to the Phono center pin XLR Pin 3 (-) to the other signal wire and to the Phono sleeve

Unbalanced Connections with Single Conductor Cable

In some cases it may be necessary to use single-conductor cable to adapt to unbalanced devices. These cables are considerably more susceptible to interference and grounding problems than the two conductor cables shown above. Two-conductor cables should be used whenever possible.

The wiring method for unbalanced connections with XLR connectors to unbalanced 14 " phone connectors (tip and sleeve only) using coaxial cable (1 wire + shield) is as follows:

XLR Pin 1 (GND) no connection XLR Pin 2 (+) to signal wire and to the 14 " phone tip XLR Pin 3 (-) to the cable shield and to the 14 " phone sleeve

The wiring method for unbalanced connections with XLR connectors to unbalanced RCA/Phono phone connectors using coaxial cable (1 wire + shield) is as follows:

XLR Pin 1 (GND) no connection

XLR Pin 2 (+) to signal wire and to the Phono center pin

XLR Pin 3 (-) to the cable shield and to the Phono sleeve
