DAB-801 DataPort Amplifier Backup Component

The DAB-801 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.

IMPORTANT:   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.

IMPORTANT:   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

Displays the current status of the DAB-801 both in text and color. The following is a list of possible status colors, and some example conditions.

NOTE:  These conditions are examples, and may not be applicable to all components with a Status field.

OK – Green – (0) – Audio is good, hardware is good.

Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.)

Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.)

Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware.

Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad.

Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.

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

Alarm/Page Active

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.

User-defined

Location

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

User-defined

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.
