Status/Control (DAB-801)
The DAB-801 DataPort Amplifier Backup extends Q-SYS redundancy capability to include designated QSC power amplifiers and I/O Frames populated with Q-SYS DataPort cards.
The DAB-801 provides N+1 amplifier redundancy for QSC 2 and 4-channel DataPort amplifiers, and supports I/O Frame redundancy. Two DAB-801s can be stacked to provide double the primary amplifier redundancy.
- A single DAB-801 supports four 2-channel primary amplifiers with one 2-channel backup amplifier, or two 4-channel primary amplifiers with one 4-channel backup amplifier.
- A pair of DAB-801s support eight 2-channel primary amplifiers with one 2-channel backup amplifier, or four 4-channel primary amplifiers with one 4-channel backup amplifier.
Note: The DAB-801 does not support 8-channel amplifiers.
The DAB-801 is a physical piece of hardware represented by a virtual Component in the Inventory list of Q-SYS Designer. This topic covers the virtual Component.
Note: Read the DataPort Amplifier Backup Panel topic and the DAB-801 User Manual for information about the capabilities and functionality of the hardware.

Status LED |
This LED changes color to indicate the current status. See Status for the meanings of the various colors. |
N / A |
Status |
Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:
|
N / A |
Panel Power Good |
LED indicating the status of the DAB-801 Panel power. |
Green/On = Good Off = Bad |
Backup Amp Power Good |
LED indicating the status of the Backup Amplifier connected to the DAB-801. |
Green/On = Good Off = Bad |
Backup Amp engaged |
LED indicating that the Backup Amplifier is in use, or engaged - one of the primary amplifiers has failed. |
Off = Not Engaged On/Red = Engaged |
LED indicating that the Alarm or Page mode is active. When the Alarm or Page mode is active, regular input to the amplifiers (per hardware settings) is suspended, and there is direct input to the amplifiers from either the alarm system or page system. Alarm takes precedence over Page. |
Off = Not Active On/Red = Active |
|
Automatic Mode |
When this button is engaged, you are not able to manually engage the Backup Amplifier. This should be on for normal operation. When an amplifier fails, the Backup is automatically switched in. |
Off = Manual On/Green = Automatic |
Reset |
Pressing this button resets the DAB-801 back to the Primary Amplifiers. |
N / A |
DataPort |
Label indicating the DataPort connector, on the DAB-801, associated with the information directly below. There are four DataPort connectors (A - D) on a single DAB-801, and four more (A - D) on the Extension Panel. |
N / A |
Channel |
Label indicating the channels associated with the DataPort connector on the DAB-801, as labeled directly above. |
N / A |
Amplifier Status |
LED indicating the status of the associated amplifier. |
Green = Good Red = Bad Yellow = Wait |
Backup Engaged |
LED indicating if the Backup Amplifier is Engaged for a specific DataPort (2-channel amp) or DataPorts (4-channel amplifier). |
Off = Not Engaged On/Red = Engaged |
Manual Backup Engaged |
Toggle button allowing you to manually switch a single DataPort for 2-channel, or two DataPorts for a 4-channel to the Backup Amplifier. When this button is pressed, the Backup Engaged LED (for the associated DataPort(s)) and the Backup Amp Engaged LED (for the Backup Amplifier) are On/Red. This is a radio-style button allowing only one button on at a time. |
Off = Not Engaged On/Red = Engaged |

Name |
User-defined name to identify the DAB-801. |

Location |
User-defined name that groups the amplifier with other components in the same physical location, or in the same organizational scheme. |

Amplifier Channel Count |
You can have either 2- or 4-channel amplifiers connected to the DAB-801. You cannot have both connected to the same DAB-801. This property selects the channel count of the amplifiers. |
2-Channel 4-Channel |
Dual |
Specifies if you have a single DAB-801, or two connected together. |
No = Single Yes = Two |
Mute On Alarm |
Specifies if you want the I/O Frame to mute its output to the DAB-801 when a signal is detected from either the Alarm or Page analog inputs to the DAB-801. This applies to all channels. The DAB-801 hardware disconnects the channels designated by the Alarm/Page switch from the main inputs, and connects them to the Alarm or Page inputs, so regardless of this setting, the Alarm/Page overrides the selected channels. |
No = do not mute Yes = mute on alarm |
1. There are four DataPort connectors on a single DAB-801. Each DataPort connector carries two amplifier channels. You can have four 2-channel amplifiers, or two 4-channel amplifiers connected to a single DAB-801. With an extension DAB-801, you can have eight 2-channel amplifiers or four 4-channel amplifiers. The backup amplifier must be the same channel count (2- or 4-channel) as all the primary amplifiers. |
