DL107, DL207 and DL210 2.0 Digi-Loop™ DSP Induction Loop Amplifiers

7f2. Loop Test
The Loop Test function performs a test algorithm to verify that the
load falls within the acceptable range of 0.5 Ω to 3.0 Ω. If the load
is outside this range (essentially open or shorted) the test will show
“FAULT”.
Note that when running a single loop in dual-loop mode, a “FAULT”
is acceptable for the output with no loop connected. However, in
this case, the unused loop output should be turned off in the menu.
This tool is to verify that a connected loop does not have an open
(break) in it.
7f3. Version
Version is an info screen that shows the firmware version of the
bootloader chip, main processor chip (CPU), DSP chip#1, DSP chip
#2 and the ethernet card firmware version.
7f4. DL107/207/210 Name
The DL107/207/210 Name provides the ability to give the amplifier
an 8-character name for easy identification when connecting to it
through the PC App on a network. This name will show up on a
drop-down list in the PC App as an available device to connect to.
For example, if 5 amplifiers were connected on the network, and the
third amp was designated for the Ballroom, you could connect to
“Ballroom” amplifier to make changes to that amp’s settings.
7f5. NET Info
This screen is for viewing Ethernet and Dante parameters of the
amplifier. No changes can be made from this screen.
Four parameters can be viewed here: (1) Ethernet Address and MAC
address of the ethernet card, (2) Ethernet Address and MAC address
of the Dante card, (3) the Dante Card Name, and (4) the Default
Dante Card Name. To set the ethernet parameters, see section “7c
Ethernet”. To set the DL107/207/210 Name, see the previous section
“7g4 DL107/207/210 Name”. To set the Dante parameters, use
Dante Controller. (For more information about installing/using Dante
controller, please visit Audinate’s website: https://www.audinate.
com/products/software/dante-controller).
7f6. Amp Temp
The temperature of the two amplifier output stages and the CODEC
(audio processor chip) can be monitored here. A “zz” by the
temperature means that the amplifier is in sleep mode (see “7f.
Power Save” for how to adjust when the amplifier goes to sleep).
7f7. Reset All
This resets all of the settings back to factory defaults -
except
the
Ethernet and Dante Network Settings. Any other user-entered
information will be lost. The amplifier may need to be rebooted after
the factory reset is performed to change states. For example, if the
amplifier goes to sleep it may still be asleep until it gets rebooted.
Note: The PC App gives the user the ability to save all settings to a
configuration file for recall later. In this manner, all settings can be
erased (here) to bring the amplifier back to a known state (factory
defaults) for troubleshooting purposes, etc. Then if desired, a saved
configuration can be loaded back into the unit via the PC App. It is
good practice to store backup configurations in a configuration file
(see PC App section) if much work has been done to finely adjust
the amplifier.
