Press the mode button until it fast blinks (3 times) after 5 s, release
it within 2 s after it has blinked. This will reset the amplifier to auto-
IP and it will toggle the Ethernet mode and update the "Switched"
indicator:
• Unlit: This is the default "split mode". The internal Ethernet
switch is disabled => the two ports are not connected and the
right port is then internally assigned for Dante/AES67. The left
port is only for control/monitoring.
• Lit: The internal Ethernet switch is enabled => the two ports are
connected and will both work for Dante and control/monitoring.
It means that you only need to connect with one cable for control
and audio. It also means that the product can be inserted in a
daisy chain of other Gigabit Ethernet products as long as there is
enough bandwidth.
Step 4 - Routing and control via GPI
Dante/AES67 (AD models)
Dante &/ AES67 is enabled and it has priority over the corresponding
analog input if there is an audio signal coming over the network.
This could be configured in the Dante Controller or in a third party
plug-in.
4 Channel models
The analog 1 is always a mix on the unbalanced and the balanced
analog 1; same with analog 2. The unbalanced input will get a 6 dB
boost so that normal unbalanced sources will deliver enough level
to drive the amplifier to full power.
Otherwise the amplifier will have straight 4 in 4 out routing and the
4 GPI inputs can be used with a 10kohm passive pot to attenuate
the levels. If a different routing or a different functionality of the
GPI pins is desired, then the software needs to be used redefine
the functionality of the GPI pins. Please look at the Advanced
configuration (with software) instead.
2 Channel models
The default here is that
• Whatever signal is delivered to output 1 is also delivered to
output 3 (but without the highpass filter). The level of these
outputs can be attenuated with GPI1.
• Whatever signal is delivered to output 2 is also delivered to
output 4. The level of these outputs can be attenuated with GPI2.
Inputs 1 and 3 are mixed. Inputs 2 and 4 are mixed. This means
that a balanced or unbalanced source can be used. It's possible to
defeat this mixing by connecting GPI3 to GND. When this is done
GPI4 defines which input signal pair is used with an external contact
closure between GPI4 and GND. Open → the balanced inputs are
used; Closed → the unbalanced inputs are used.
