Analog Input (MPA-Q)

Tip: For additional properties that are not listed, refer to the Properties Panel help topic for more information.

MPA-Q Amplifier Properties

Is Network Redundant

Selecting Yes allows a device to maintain network connectivity even if one network path fails. If a network problem occurs, the secondary network takes over automatically.

Channel Configuration

Select the configuration needed for your venue.

Note: Eight-channel models have two sets of four channels for configuration.

• 4 Channel, A B C D
• 3 Channel, A B C+D Bridged
• 3 Channel, A+B Bridged C D
• 2 Channel, A+B Bridged C+D Bridged

Channel configurations are as follows: 

• Space between letters (A B C D) = single channels,
• "+" between letters (A+B) = bridged.

When you make your selection, then run the design, the configuration is made available to the amplifier. Follow the instructions on the amplifier display.

Standalone Mode

Off – Turns Standalone Mode off.

One-to-one – Each audio input is routed to its corresponding output Ch1 – Output A, Ch2 – Output B, Ch3 – Output C, Ch4 – Output D.

One-to-all – Input Channel 1 is routed to all outputs.

Note: See the Standalone section below for details.

The controls for the Amplifier Status component, listed below, are divided into sections to match the Control Panel sections.

Analog

Peak Input Level (dBFS)

Meters for each channel indicating the peak analog input level. The measurement is taken after the A/D converter, but before the Digital Gain. Use this meter in conjunction with the Max Input Level to obtain an input signal as close to 0 dBFS as possible without actually clipping.

Clip

Red LED indicating if the signal is being clipped.

Clip Hold

Holds the clip indication until manually cleared.

Preamp Sensitivity (dBu)

The maximum analog level, coming into the Analog Input, that can be converted without clipping. This level is typically set slightly higher than the source's output level, so that the Peak Input Level reads about 0 dBFS without actually clipping.

You can select the field and enter the value you want, or click and drag the number to the value.

Also known as Analog Sensitivity or Line Level Sensitivity.

Digital

Invert

Toggle button to invert the digital output of Analog Input.

Mute

Toggle button to mute and unmute the output signal.

Gain (dB)

Controls the Gain of the digital output signal. Range is between -100 and 20 dB.

Status

Status LED 

This LED changes color to indicate the current status of the amplifier. See Status for the meanings of the various colors.

Status

Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:

• OK: The device is functioning normally.
• Initializing: The device is in the process of a firmware, patch, or configuration update, or the design is starting.
• Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
• Missing: The device cannot be discovered.
• Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
• Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
• Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.
