Group Signal Type
A group is configured for analog or AES/EBU digital audio. Certain products only have analog or
AES/EBU digital inputs. You cannot include products in a group reproducing selected audio type
(analog or digital), if these specific products do not have the correct input type available. If a
selected audio signal type is not supported by a monitor or subwoofer, it will be automatically
marked as not belonging to the group (we call this Group OFF and indicate it with a yellow glow
around the product in the GLM window and a yellow LED color showing on the actual product
(Note: If using SE7261 and 8130 monitors (non-SAM monitors), 8130 monitors indicates valid
digital signal with yellow LED).

AES/EBU subframe A and B selections
For AES/EBU digital audio, the channel assignment needs attention. Typically AES/EBU cables
carry two channels of audio, called subframes A and B. In a stereo system the subframe A is
usually assigned to the left channel and the subframe B to the right channel. A multichannel audio
presentation, using more than one digital audio cable, will split the channels into cables. The
correct selection is needed for each monitor and subwoofer.
GLM 2.0 defaults to the common AES/EBU channel assignments (subframe A is left, B is right).
To edit specific group settings for individual monitor or subwoofer, single-click on the monitor or
subwoofer icon. The icon starts to blink. Also the monitor blinks its green LED. A settings panel
opens. You can
 rename the monitor to facilitate easy recognition
 include or exclude a monitor in the group using the ‘Active In Group’ selection
 determine if the subwoofer crossover frequency is globally the same for the whole group or
specific to the product (monitor or subwoofer) only
When using SE7261, digital AES/EBU subframe A and B must be selected from the back panel of
the 8130 monitors.
For subwoofers, you can also
 set the subwoofer crossover frequency
 set the LFE channel gain (0 or +10 dB)
