NETWORK / AVB PORTS
Network/AVB

Network/AVB Connectors
CAL's two Network / AVB ports use RJ-45 Ethernet connec-
tors and allow the loudspeaker to be connected to a stan-
dard computer Ethernet port, network router, or network
switch with a CAT-5e cable. CAL's Network / AVB ports are
AVB-enabled and use the IPv6 protocol for network commu-
nication. Two ports are provided for redundant control and
each has an independent Media Access Control (MAC)
address that is static and preassigned.
The yellow and green LEDs indicate connection and data
traffic as on standard Ethernet ports.
When CAL is connected to a Mac or Windows-based com-
puter, the Compass control software lets you configure
beam spread and beam angle and upload the settings as a
preset to CAL. Compass also includes an RMS tab for
remote monitoring of all CAL loudspeakers on the network.
AVB Audio Stream Input
AVB audio streams received from CAL's Network / AVB
ports can be used as audio sources. In the Compass control
software, AVB audio streams for the connected port can be
specified as the active input or override input.
OLED BUTTON
The OLED button is located in the upper right of the CAL
user panel and provides visual feedback on the unit. During
startup, the OLED displays CAL's Network port addresses.
The addresses can also be viewed after startup.
To view CAL's Network port addresses:
1. Press and hold the OLED button until the addresses
appear.
■
The address for the left Network port is displayed when
the OLED button displays a left arrow.
The address for the right Network port is displayed when
■
the OLED button displays a right arrow.
AMPLIFIER COOLING SYSTEM
CAL employs a combination of natural convection and
2
forced air in its cooling system. The amplifier's heat sink pro-
vides natural convection cooling from the air flowing near its
fins. In addition, a single-speed fan circulates air internally to
ensure that CAL remains operational when exposed to high
ambient temperatures or when driven continuously at high
output levels.
USER PANEL COVER
A user panel cover is included with CAL to protect the con-
nectors from dust in indoor installations and the weather
elements in outdoor installations. The cover is installed by
default and must be removed to gain access to the user
panel.
CAL User Panel Cover
CAUTION:
The CAL heat sink can reach tem-
peratures up to 85° C (185° F) during extreme
operation. Use caution when approaching the rear of
the loudspeaker.
CAUTION:
When installing CAL outdoors, the
user panel cover should always be attached to
protect the user panel connectors from the weather
elements.
