DriveCore Install DA Series Operation Manual
Application Examples
Dual Mode High-Z (70Vrms/100Vrms) Output Operation
Typical input and output wiring, along with
software settings, are shown in Figure 11 and
Figure 12
.
Inputs
If using analog inputs, connect the inputs with
wiring in place for each channel. If the same signal
is to drive both outputs of a channel pair, the input
signal can be sent to adjacent amplifier channels
using the "Y" options (see Figure 12 ).
Outputs
Maintain proper polarity (+/–) on output
connectors. Connect the channel 1 speaker’s
positive (+) lead to the amplifier channel 1 positive
terminal; repeat for negative (–). Repeat channel
2 wiring as for channel 1, and for any subsequent
channel pairs on multichannel models.
Dante
When connecting via Dante, two Dante-equipped
devices can be connected directly together using
the Primary Dante ports. If connecting more than two Dante devices, the Primary ports of each device should be connected to a network switch (this is a referred to as a
"star" network topology).
100Mbps network switches and Category 5 cabling can be used for smaller Dante networks, where smaller channel counts and/or lower sample rates are used. For optimum
performance and improved reliability, a Gigabit network and Category 5e or Category 6 cabling should be used. Visit the Audinate website for more information.
To provide fault protection when using Dante, connect the Secondary ports of all Dante devices to a secondary (separate) network switch. If any "primary" cable connections
or the "primary" switch fail, the "secondary" Dante network will automatically take over.
For further information on Dante, refer to
"Using Dante" on page 37
.

NOTE:
A 35Hz high-pass filter is automatically inserted when an amplifier output channel is configured for high-Z operation.
NOTE:
Amplifier outputs can be independently configured for high-Z or low-Z operation, while 70V/100V selection is global.
NOTE:
Always route the input and output wires in separate bundles.
WARNING:
Only connect to networks that remain inside the building.
