Audio Meters & Groups:
As with the video signal(s), each SDI signal may contain up to sixteen channels (8 pairs) of
embedded audio. Typically, 48kHz, 20-bit audio; (extendable to 48kHz, 24-bit audio).
Use the “Group” setting to select which group of embedded audio to monitor. In accordance with
SMPTE standards, incoming audio may be embedded in up to 4 groups with each group
containing 4 channels. For example; a simple stereo signal would typically use: Channels 1 & 2,
which can also be thought of as Meter 1-Left & Meter 1-Right. An embedded 5.1 surround sound
signal would typically use: Ch1-Left, Ch2-Right, Ch3-Center, Ch4-Subwoofer, Ch5-Right
Surround, Ch6-Left Surround. The Pacific C-SHS is capable of displaying 8 Channels (2 Groups)
at a time. Meters 1 & 2 are always displayed on the left side of the screen and Meters 3 & 4 are
always displayed on the right of the screen. However, you can associate any Group to any “set” of
meters. For instance, Group 2 could be displayed on the left side of the screen.
Note: when interfacing with advanced/custom installations, there may also be audio embedded on
channels 9-16.

Recap:
Any of the 4 Groups can be assigned to Meters 1 & 2, and any of the 4 Groups can be assigned
to Meters 3 & 4. However, Meters 1 & 2 and Meters 3 & 4 can never share the same group. For
example; Group 1 can never be set to Meters 1, 2, 3 & 4 simultaneously.
Note:
When changing the audio meter settings through the Pacific’s LCD interface, the names are
abbreviated. For Example:
 METER12: GROUP1 – This means Group 1 is assigned to Meters 1 & 2.
 METER34: GROUP2 – This means Group 2 is assigned to Meters 3 & 4.
Upon changing the audio source entering the “SDI IN” port, make sure to refresh the audio meters
by either re-selecting the “ON” option within the audio meter menu or by physically disconnecting
and reconnecting the signal cable to the “SDI IN” port. Refreshing the audio meters is necessary
for Meters 3 & 4 to display the correct dynamic meter bars.
