The DDB-BN31 is a complete wall-mounted Dante audio network interface. It
features two XLR mic or line inputs, one stereo Mini-jack line input and one stereo
Mini-jack line output on the front panels, plus two line outputs on a rear-panel
detachable terminal block. Special software is not required to configure the DDB-
BN31. Each XLR input provides three switches that may be set from the front of the
unit when the cover plate is not installed. One switch enables or disables P48
phantom for that input; the second switch selects the mic or line gain range; the
third switch sets the gain. The Mini-jack input provides a switch to configure the
input for stereo or summed mono. The Mini-jack output provides a switch to configure
the output for stereo or left-channel mono. Each rear-panel output provides a switch
to set the output to balanced professional or unbalanced consumer level. The DDB-
BN31 fits a standard US dual-gang electrical box or an RDL WB-2 back box for
installations in thinner European or equivalent walls. The DDB-BN31 is PoE powered,
and is available in multiple finishes with optional customized graphics.
The two XLR inputs are each converted to a separate Dante network transmit
channel. Three gain settings are switch-selectable for both the mic and line input
ranges to match condenser or dynamic mic levels and standard line levels.
The Mini-jack left and right inputs are each converted to a separate Dante
network transmit channel. Each input provides a network digital audio level of -20
dBFS for an unbalanced -10 dBV input. The input is equipped with a selector to sum
the left and right Mini-jack inputs. The summed signal feeds both Dante transmit
Two Dante audio channels are converted to unbalanced line level to feed the front-
panel Mini-jack. Each channel provides -10 dBV unbalanced for a network digital
audio level of -20 dBFS. The left and right Mini-jack channels are normally fed from
Dante receive channels 3 and 4 (stereo). The Mini-jack output is equipped with a
selector to feed both output channels from Dante receive channel 3 (mono). This
selector may be set from the front of the unit when the cover plate is not
Two Dante audio channels are converted to balanced line level on the rear-panel
detachable terminal block. Each output provides +4 dBu balanced for a network
digital audio level of -20 dBFS. Each output is equipped with a selector to
unbalance the audio and attenuate the level to -10 dBV. These switches are located
on the top of the chassis and are set by the installer prior to mounting the unit.
The rear-panel outputs are intended for connection to RDL AMS connectors mounted
in Decora-style plates that match the DDB-BN31. AMS audio connectors include RCA,
Mini and XLR jacks. The output plate may be located together with the DDB-BN31 in a
triple gang box or may be mounted remotely in a single box.
Valid PoE power and synchronization to the Dante network are indicated by green
LEDs visible from the front of the unit.
The DDB-BN31 is a professional grade product with discrete mic preamplifiers for
studio quality fidelity and low noise performance, coupled through metal XLR jacks
housed in a stainless steel chassis with dual powder-coated or stainless steel
Decora front plates.
The DDB-BN31’s superior performance specifications make it ideally suited
to the most demanding installations, and an exceptional value in commercial
networked audio systems. This full-featured product is engineered and manufactured
in the U.S.A for continuous duty in demanding installations. Designed to outperform.
