potential electric shock or fire hazards.
To avoid defeating the safeguards that have been built into the device, please observe the precautions discussed
in this document.
Warnings on the external power supply
The lightning flash with arrowhead symbol, within a triangle, is intended to alert you to the presence of
uninsulated “dangerous” voltages within your device’s enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within a triangle is intended to alert you to the presence of important instructions in the
literature accompanying the device.
Other warnings
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER OF THE DEVICE.
THERE ARE NO USER-SERVICEABLE PARTS INSIDE IT.
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS DEVICE TO RAIN OR MOISTURE.
DO NOT PERFORM ANY SERVICING UNLESS YOU ARE QUALIFIED TO DO SO BY FOUR AUDIO.
REFER ALL SERVICING TO QUALIFIED SERVICE PERSONNEL.
SERVICING THE DEVICE YOURSELF WILL INVALIDATE THE WARRANTY.
Ventilation
Slots and openings in the casing of the device are provided for ventilation, to ensure reliable operation of the
device and to protect it from overheating.
Never block the ventilation openings by placing the device on a bed, sofa, rug or other similar surface;
Never cover the ventilation openings with items such as newspapers, cloths etc.
Do not place the device in a built-in installation such as a bookcase or rack unless proper ventilation is provided
or you have adhered to the manufacturer’s instructions.
Water and moisture
Do not expose this device to dripping or splashing and ensure that no objects filled with liquids, such as vases,
are placed on the device
Disposal
When the end-of-life of your device is reached, do not dispose this device in the household waste. This protects
our environment and saves raw materials. Return it to your distributor who will dispose it free of charge for you.
KEEP THIS INFORMATION FOR FUTURE REFERENCE

5. DBS1 Inputs/ Outputs
The DBS1 provides 2 balanced analog inputs and 2 balanced analog outputs for audio.
5.1. Analog Inputs
The analog inputs provide a dynamic range of 115 dB(A) with a maximum input voltage of 30 dBu.
Following functions are available:
Sensitivity +30 / +21 / .. / +3 / 0 / -3 /.. -42 / -45 dBu 3 dB steps
48 V Phantom Power On / Off
70 Hz / 1st order low cut filter On / Off
(Bold values are factory default)
The two input channels will appear as Channel 1 and 2 of the DBS1 device in the Dante® Controller Software.
5.2. Analog Outputs
The analog outputs provide a dynamic range of 114dB(A) with a maximum output voltage of 15 dBu.
Following functions are available:
Sensitiviy -48 dBu .. 15 dBu in 3 dB steps
Phase Invert 0° / 180°
Mute On / Off
Both output channels will appear as Channel 1 and 2 of the DBS1 device in the Dante® Controller software.
5.3. Ethernet connector
The DBS1 has one RJ-45 Ethernet connector to connect the unit to a Dante® Primary network. For information
about how to set-up a Dante® network please check Audinate’s help site and the famous Dante FAQ
https://www.audinate.com/resources/faqs
5.4. Power Supply jack
Use the supplied 5 V desktop power supply or Power over Ethernet (PoE).
The external power supply and PoE can be used simultaneously to achieve redundancy.
The metal bracket on the rear provides a pull relief.

6. Usage
The DBS1 was designed as a hassle-free plug-and-play device. This chapter describes all buttons and LEDs to
ensure you’ll get the most out of your Dante® Breakout box.
On the Front panel you’ll find all controls and LEDs which are explained below. The function of some elements
can change depending on whether an input or an output is selected.

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!
