All Stewart Audio products will ship from the factory with the
name Ultimo-<MAC>. This can be renamed within the device con-
figuration in the Dante Controller software.
Transmitters are shown on the top of the matrix while Receivers are
shown on the left-hand side. The DSP100 Series amplifiers include 2
receive channels. In order to make a connection, click on the matrix
node between the appropriate transmitter and receiver. If a connection
is successful, it will display a green checkmark.
Note: All network-enabled DSP100 amplifiers are shipped from the
factory with
network
input 1 routed to
local
output 1 (via the in-
ternal DSP software mixer). If the DSP100 model has more than
one local output, the corresponding network input is routed to the
local output with the same number designation. This can be
changed as desired via the DSP Control Center software.
3.4.2 Dante FAQ
Q: I am having problems installing or using the Dante Controller Soft-
ware.
A: Please refer to the official documentation available in the Audinate
portal where you downloaded the Controller Software.
Q: I do not see the DSP100 Series amplifier showing up on the net-
work?
A: All Stewart Audio products are tagged as Ultimo-<MAC_ADDRESS>
from the factory. You can find a specific Ultimo device by choosing the
device’s MAC address from the list. You can rename this using the
Dante Controller software.
Q: I routed an audio signal to network input 1 of the FLX amplifier using
the Dante Control Center software, but hear no output from the amplifi-
er.
A: Check the settings in the matrix mixer (using the DSP Control Cen-
ter software) to be certain that network 1 is routed to a local output.

3.5 Remote Volume Control
DSP100 Series amplifier volume can be remotely controlled (or muted)
via the input on the rear of the amplifier. An external potentiometer,
which can be located wherever convenient, controls the output volume
of all channels. Remote muting is also useful for fire-alarm situations in
which all unnecessary sound must be silenced.
NOTE: The remote volume control connector attenuates
the signal level from the level set by the DSP settings. It
cannot increase the signal level above those settings, nor
does it change those settings.
NOTE 2: The remote volume control is disabled when the
USB cable is connected to the device even
if a connection
has not been established between the DSP Control Center
and the device.
Remove the USB connector to use the
remote volume control.
In order to remotely control the volume of the unit, a 10k-ohm, linear
taper potentiometer should be placed between the +10V pin and the
GND (Ground) pin on the rear of the unit with its wiper on the RVC pin.
The volume will be determined by the selected resistance on the po-
tentiometer, the greater the resistance the louder the volume.
The amplifier can be remotely muted by making a connection between
the GND pin and the MUTE pin. No power should be applied to these
pins, simply a contact connection.
