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.
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 Lynx L22 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 Lynx L22 when using the Lynx L22 Mixer application and
to select audio devices in third party applications.
In the Lynx L22 Mixer, the adapter that a user wishes to control is selected from the
Mixer pull-down menu. In a system with four Lynx L22’s the adapters will be listed as
follows:
Lynx L22 1 Mixer
Lynx L22 2 Mixer
Lynx L22 3 Mixer
Lynx L22 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 Lynx L22’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 “Lynx L22 2 Play 1”.
Selection of Master and Slave Clocks
In order to select master and slave Lynx L22’s in a system, each adapter ID must be
first physically associated with a Lynx L22 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 Lynx L22 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 “Lynx L22 1 Play 1” as the playback device.
