Connecting the HPA-DAC4 to a Dante

Network

Refer to the example below on how to connect a simple Dante

network audio system. There are

three items needed to make a Dante

network, (1) gigabit router, Dante

transmitter and a Dante

receiver. In the illustration example below the AtlasIED BlueBridge

BB-168DT is the transmitter

and the HPA-DAC4 is the receiver. The HPA-DAC4 installed into the HPA amplifier becomes the HPA

amplifier’s Inputs 1-4. The router and the CAT5e cable connect the devices together.

Figure 5 is a configuration snapshot of the GUI of the BB-168DT. Analog inputs 1-4 are routed to a

limiter, then onto the network outputs 1-4. Where signal goes from the BB-168DT network output is

determined by a separate software called Dante

Controller. Dante

Controller is free software that

allows connectivity and signal routing within Dante

devices.

Figure 6 shows the BB-88DT and HPA-DAC4 on the Dante

Network. The HPA amplifier model number

will not appear in the Dante

Controller GUI because the amplifier is not the recognized Dante

device, the HPA-DAC4 is. The accessory card installed in the amplifier combines the digital and

analog platforms. The cells that have been connected are indicated by the green highlighted circle

with the check mark. These highlighted cells indicate the routing of the BB-88DT transmitters

01, 02, 03, 04 (BB-88DT network output 1, 2, 3, 4) to the HPA-DAC4 (Atlas4-0a004b) receiver channels

1, 2, 3, 4 (HPA amplifier inputs 5-8).

Figure 5

Note:

Always

add a limiter

before the

network output.

Set the limiter

threshold to

0dBu to prevent

clipping the

input of the HPA

amplifier.

Figure 6

Green check circles

indicate a specific

channel connection

between the Dante

transmitting device

and the Dante

receiving device.

Note:

Can be

renamed in Dante
