6.3. Channel selection
To select the active channel use the SEL button. With each
press of a button the DBS steps through six states of
channel selection as shown on the right. The yellow
channel LEDs show the active selection.
All changes made using the remaining four functional
buttons (page 12) are applied to those channels whose
LED is lit.
The function of each key changes depending on whether
an input or an output is selected. See explanations in the
next chapters.
Hint: If two channels are selected the LEDs are showing
settings of channel 1 only! There is no indication if Ch. 2 has different settings to Ch. 1! Parameter changes are
relative to the current setting of channel 1 and copied to channel 2. Keep this in mind when different source
signals like a microphone and a line signal are connected.
6.4. Sensitivity
The front panel provides 8 LEDs which indicate the current input or output gain. As there are more than 8 steps
in gain these “fine steps” are shown as a combination of two LEDs. The tables below show the gain settings.
Info: Bold values are factory default
To change the sensitivity of a channel follow these steps:
1. Make sure the correct channel is selected. Push the SEL button until the desired channel LEDs are lit
2. Use the SENS buttons to change the output or input sensitivity according to Table 1 or Table 2
At the rear panel you’ll find a summary of both tables:
The output sensitivity indicates which analogue signal level (in Volts or dBu) is to be expected at the
maximum digital signal level (fullscale, FS) over Dante®.
The input sensitivity indicates which analogue signal level (in Volts or dBu) can be applied before the
digital maximum level (fullscale) is reached. Never exceed this level because this will lead to distortions!

7. Network Setup
A Dante®- device that is connected to a network will automatically set up its network configuration including IP
address settings.
On a network with DHCP server, which may be the case for installed networks, the DBS1 will receive an IP
address using the standard DHCP protocol.
On a network without DHCP server, which may be the case for temporary or smaller networks, the Dante®-
device will automatically assign itself an address using link local protocols, in the same way PCs and printers
often do.
If you directly connect the DBS1 to your computer, both devices will automatically negotiate their IP addresses
using link local protocol. Alternatively, you can run a DHCP service on your computer to assign an IP address to
the DBS1 and to your computer.
Please also check the official Dante® Controller User Guide at
http://dev.audinate.com/GA/dante-controller/userguide/pdf/latest/
Once the DBS1 is correctly integrated in your network, you can change its IP settings in the Dante® controller
software.

9. Firmware Update
To update the DBS1 firmware, follow the instructions below. Please make sure you have a reliable power supply
and network connection.
The DBS1 contains two central chips: The Dante® Ultimo chip and a controller chip by Four Audio. Therefore, the
update requires multiple steps. The first step is a preparatory update for the Ultimo chip. Then, update the DBS1
controller chip and finally install the latest Ultimo firmware.
To update the Dante® Ultimo firmware, third party software from Audinate has to be used.
Please follow exactly the steps described here. Do NOT just update the Dante® Ultimo firmware
without also updating the Four Audio firmware, as this will lead to malfunction.
9.1. DBS1 Software and firmware
Download and install the latest DBS1 Software from http://four-audio.com/en/downloads.html.
Download the latest set of firmware files http://four-audio.com/data/latest_dbs_firmware.php and unzip it:
DBS1_ult-preparatory.dnt (preparatory firmware for Dante® Ultimo chip)
DBS1_<version>.fwu (firmware for Four Audio Controller chip)
DBS1_ult-<version>.dnt (firmware for Dante® Ultimo chip)
README.txt (update instructions)
9.2. Dante® Firmware Update Manager
Download and install the latest Dante® Firmware Update Manager (v.1.4.16.6 or later) from Audinate.
https://www.audinate.com/products/firmware-update-manager
9.3. Dante® Controller
Download and install the Dante® Controller.
You’ll find it under https://www.audinate.com/products/software/dante-controller
It is strictly recommended to disconnect audio output or turn off connected devices during the update
procedure because loud click noise can occur!
9.4. Performing the preparatory Ultimo update for old Dante
Software versions
Because of major changes in the Ultimo and Four Audio
Controller firmware, a preparatory Ultimo firmware update
is required if the Ultimo firmware is lower than 2.2.3.1.
Open the Dante® Firmware Update Manager, select your
network, and then choose Update Dante Firmware. Load the
DBS1_ult-preparatory.dnt firmware file. The Update Manager
will scan for your DBS1 devices.

Date: 2016-02-18
DBS1 user manual
16
If the displayed Ultimo Software Version of your device is lower than 2.2.3.1, you need the preparatory update
(otherwise go to 9.5 directly).
Select the device and click Start in order to upgrade to the preparatory Ultimo software.
Restart the DBS1.
After the update, the Ultimo Software Version will be
2.0.0.9. Even if it was the same number before, the
update has worked. Inside the Dante Controller, you
can verify that the Device Firmware Version has
changed to 15.11.5.
9.5. DBS1 controller firmware update
Start the Four Audio DBS1 software. If you have several
network cards installed in your computer, choose the correct
network interface. In the list displaying the DBS1 units found
in the network select the device that is to be updated.
The status bar shows the version of the Four Audio
Controller Firmware.
Now go to Device => Firmware Update browse to
DBS1_<version>.fwu. Open starts the firmware update.
During the update process, you can hear relays clicking inside
the DBS1.
After closing the Update dialog and pressing 'Refresh' the status bar shows the new firmware version.
9.6. Final Ultimo Update
Update the Ultimo chip with Dante® Firmware Update
Manager to version DBS1_ult-<version>.dnt.
Congratulations, your DBS1 is up-to-date now.
In Dante® Controller you should find your device with the
latest Firmware versions now:

10. Troubleshooting and FAQ
10.1. Dante® firmware update fails
If the Dante® firmware update failed, the Dante® Firmware
Update Manager reports an error message like shown on the
right and the SYNC and SYS LEDs of DBS1 are flashing red. The
Dante® Controller reports that the device has entered failsafe
mode.
To solve this issue, the DBS1 needs a static IP address for the
firmware update even if it is running in a network with DHCP
server or local link configuration.
Follow these steps:
1. Power cycle the DBS1. It will start with the previous firmware.
2. Choose two IP addresses within the same subnet.
3. Connect the DBS1 directly to the network socket of the computer.
4. In Dante® Controller set the IP of the DBS1 to one of those addresses and press ‘Apply’.
5. Set the IP of the computer to the other IP address as chosen above.
6. Perform the upgrade again
7. Restore the original network settings on the DBS1 and the computer
Hint: To simplify step 2 to 5, you can temporarily assign the same IP address to the DBS1 that it had been given
by the DCHP server before and leave it on the network. Restore settings after the update.
How do I read the current IP address of my DBS1?
Open Dante® Controller and read the current IP address from
Device view => Status.
How do I change the IP settings of my DBS1?
Open Dante® Controller and go to the Network Config Tab in
the Device view

Date: 2016-02-18
DBS1 user manual
18
I have upgraded the chips in the wrong order and the DBS1 does not appear in DBS1 software
Flash the firmware DBS1_ult-2.0.0.9_5B05.dnt with Dante® Firmware Update Manager to the Dante® Ultimo
chip and start the upgrade procedure again.
The firmware upgrade for the Four Audio controller chip does not finish
It may happen that the Ultimo chip stops to communicate with the Four Audio controller chip. In that case
turn the DBS1 off and on and start the upgrade of the Four Audio chip again.
Firmware upgrade was interrupted e.g. by loss of power or network failure
If the upgrade of the Four Audio controller was interrupted, just repeat the procedure after restarting the unit.
The unit always starts with the old firmware until the upgrade was successful.
In case the Dante® Ultimo chip update fails, see Using Failsafe Recovery in the User Manual of Dante®
Firmware Update Manager.
Other problems
See Troubleshooting in the User Manual of Dante® Firmware Update Manager
http://dev.audinate.com/GA/firmware-update-manager/userguide/latest/
10.2.Network Troubleshooting
When do I expect to have network problems?
If one or several of the following symptoms occur, we recommend checking the network configuration:
Dante® Controller shows orange “unsuccessful subscription” icons, which usually means that a device
that was present earlier is now missing
Intermittent faults, which may be heard as dropped samples or “cracks” in the audio signal
Dante® devices appear and disappear in Dante® Controller
Items in the “Device View” of the Dante® Controller are greyed out
What are possible causes for network problems?
One or several of the following items can cause connection problems:
Unplugged /badly connected or faulty Ethernet cables
Misconfigured switches
Network cables not suitable or damaged (use at least 100 Mbit CAT5 cables)
Dante® devices removed or turned off
Symptoms of switch or cabling issues
IP address conflicts or configuration issues (e.g. static IP set)
How can I fix network issues?
Go through the switch and cabling checklist
Are all the connected link/status lights on the switch lit or flashing as expected?
Are all switches powered on and show no error?
Is the cable plugged in correctly at the switch and the PC or equipment?
Is the switch configured correctly?
Perhaps QoS or VLANs have been set up incorrectly
Are you using a switch from another application with an unchecked or untested configuration?
Is there a DHCP server present in the network?
If a DHCP is used check that “obtain IP address automatically” is activated
Do other devices receive an IP address correctly? We experienced that in most cases IP address
problems cause the devices not to work properly.
Try to deactivate wireless LAN / Wi-Fi on your computer

Can I use the DBS1 on a wireless network?
Audio streaming and control over wireless LAN (Wi-Fi) is intentionally blocked by all Audinate software
applications. A Dante® device will not appear in the Dante® Controller if it is connected over wireless LAN.
Do I have to deactivate my wireless LAN adaptor?
Our experience is, that Wi-Fi can be kept activated without hassle. In case of problems, especially network
problems, it is worth to check again with deactivated Wi-Fi adapter.
10.3.General FAQ
Many options, features and behaviours that a user may expect to be device specific are actually Dante® specific.
Thus, most of the following explanations are copied from the Dante® Controller user manual or online FAQ.
Consult these resources for Dante® related information:

Why does the DBS1 not detect the sample rate automatically?
Dante® supports different sample rates simultaneously within one network. So before subscribing to a
transmitting device the sample rate needs to be selected with Dante® Controller. After that, Dante® Controller
allows subscriptions to transmitting devices running with same sample rate only.
Keep in mind that the DBS1 can receive flows from different transmitting devices and auto detection of sample
rate would fail if transmitting devices are not running with equal sample rates.
Why does the DBS1 not playback audio if connected directly to a computer with Dante® Virtual Soundcard as
external soundcard?
Dante® is an audio network, not a point to point connection. DBS1 as a receiver and/or transmitter, always
needs to be subscribed to the desired transmitter even if there is only one transmitter in the network. Audio
routes are most frequently configured using the Dante® Controller software, running on any Windows or Mac
OSX computer that is attached to the Dante® network. Dante® Controller and Dante® Virtual Soundcard can be
used on the same computer.
Dante® Controller is not displaying details under Clock Status or Device Status. What's wrong?
This symptom indicates that the Dante® services cannot communicate with the Dante®-enabled devices on the
network. This may be caused by port blockage due to protection software, or by the failure of a background
service.
On a Windows PC make sure that no third-party firewalls or Internet protection products are active on the
computer. Dante® software will automatically adjust the built-in Windows firewall.
If you have multiple network interfaces (NICs) on the computer, disable any that are not being used by
Dante®.
Check the Services application (Start Menu -> Control Panel -> Administrative Tools -> Services) to see that the
Dante® Control and Monitoring service is running. Restart this service if necessary.
