SARA):
1.
System Model
2.
IP: Active when the system has obtained an IP address from a
DHCP server (router) or via Static configuration.
3.
L/Sxxxx: ID name of the system. ALMA needs a unique ID name
per device. When systems are manufactured the amplifiers are
loaded with this unique ID number*.
4.
Mute / Unmute: this symbol shows with a X on top of the speak-
er symbol if the system has been totally or partially muted by
using ALMA.
5.
Device Gain: variations of Gain (level in dB) are possible from
+6dB to -40dB in 0.1 increments / decrements.
6.
Device Delay: from 0ms to 323ms.
7.
Array Balance settings. The graph shows both, AB Low and AB
High settings.
8.
HPF filter: In case of “top” units such as SARA / LARA this part
of the display shows the active High Pass Filter (63/80/100Hz).

. Atmos. Correction enabled: As sound propagates through
the atmosphere its energy is gradually absorbed by a num-
ber of energy-exchange processes in the air called atmos-
pheric absorption. To compensate this effect Atmos. Correc-
tion filter are appied at High frequencies depending on the
ambient conditions.
