Multicast - Algo 8410 User Manual

8410 IP Display Speaker &
8420 IP Dual-Sided Display Speaker
DTMF Detection Type
Select the preferred dual-tone multi-frequency (DTMF) detection method. DTMF is a technology used with touch tone
phones, best known to users as the sound made when pressing a number key. In the 8410 or 8420, this is used for
multi-zone selection, passcode, etc.
Audio Processing
Ambient Noise Compensation
Ambient Noise compensation will allow the speaker level to adjust automatically in response to ambient noise levels
detected at the device prior to the start of each call.
Ambient Noise Compensation No Loss
Configure the Ambient Noise Compensation algorithm to only use levels at or above the current volume. The current
volume is the minimum speaker volume when this setting is enabled.
Ambient Noise Compensation Max Volume
Based on ambient noise levels, a maximum volume can be set for the speaker.
Automatic Gain Control (AGC)
AGC normalizes the audio level. This ensures the audio level heard near the speaker is always at a consistent level,
independent of the phone that is used to answer the call.
Screen
Idle Pattern
Select a pattern to be displayed on the screen for when the 8410 or 8420 is idle. Patterns can include up to several
screen displays and can vary to include a single image, a notification template, a clock display, and other
configurations.
Screen Brightness
The screen brightness level can be adjusted according to the placement of the screen within a building to optimize
visibility of content. Select a brightness level for the display screen on the 8410 or 8420.

5.2.3 Multicast

Multicast IP Addresses
