The ASB dashboard displays information about the ASB, including LEDs and temperature output that provides status of the ASB. You can also make temporary adjustments to the ASB volume using a volume slider that appears at the bottom of the ASB dashboard. The volume can be adjusted on a scale from -42 dB to 0 dB.
The dashboard displays the following fields:
Displays the model of this device. | |
Serial Number | |
Displays the Media Access Control (MAC) address, which is a unique identifier assigned to network interfaces for communications on the physical network segment. | |
Firmware Version |
Real-time statuses that can be viewed from the dashboard are described in the following table:
Channel 1/2 Status | Provides clipping status for Channel 1 and 2. Clipping is sound distortion that occurs when an amplifier attempts to deliver an output voltage or current that is beyond its maximum capability. If this indicator is green, the channel is not clipping. Red means the channel is clipping. Gray means that the appliance’s web UI is not receiving data from the appliance's web server, indicating that the ASB may be offline or rebooting. |
Protection Status | Indicates if the ASB is in partial shutdown mode to protect the built-in two-channel amplifier module. In this case, the appliance itself may remain “on” as indicated by its front panel Status and Power LEDs. However, the ASB’s amplifier module senses various faults that can be caused by factors such as incorrect speaker wiring (for example, shorts or too low an impedance). These faults can overload the amplifier output capability (overcurrent/clipping) and/or amplifier thermal conditions (overheating). If the indicator is green, the amplifier module is operating in a normal capacity. If the indicator is red, the amplifier module is in protection mode and audio will not be passed to any ASB port. If the cause is temporary or intermittent (for example, signal clipping), the amplifier module will quickly return to normal mode. If the system remains in protection mode for an extended period of time, this likely indicates some sort of wiring fault or low-impedance condition is present that must be rectified. When the indicator is gray, the ASB's web UI is not receiving protection status information from the appliance’s web server. This usually indicates that the network connection has been interrupted or dropped or that the device is rebooting. |
Temperature | Provides a snapshot of the amplifier module’s temperature in degrees Celsius during any transition (that is, change state) on the Channel 1, Channel 2, or Protection Status indicators. Note: The ASB’s UI displays the temperature reading from the latest update; it does not receive or display continuous real-time amplifier module temperature readings. |
Volume | Sets the volume for the speaker during an intercom call or page. This is a temporary adjustment that allows the user to experiment with the loudness of the speaker. To make permanent adjustments, change the various cut level settings on the Nyquist System Controller. The value can be adjusted between -42 dB and 0 dB. |
The following buttons are available at the top of all pages in the application.
