APPLICATION: The DD-BN40 is a complete wall-mounted Dante audio network interface. It features four XLR mic or line inputs on the front
panels and two line outputs on a rear-panel detachable terminal block. Special software is not required to configure the DD-BN40. Each 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. Each output provides a switch to
set the output to balanced professional or unbalanced consumer level. The DD-BN40 fits a standard US dual-gang electrical box or an RDL
WB-2 back box for installations in thinner European or equivalent walls. The DD-BN40 is PoE powered, and is available in multiple finishes
with optional customized graphics.
The four 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.
Two Dante audio channels are converted to balanced line level. 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 outputs are connected through a detachable terminal block.
The outputs are intended for connection to RDL AMS connectors mounted in Decora-style plates that match the DD-BN40. AMS audio
connectors include RCA, Mini and XLR jacks. The output plate may be located together with the DD-BN40 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 DD-BN40 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 powder-coated or stainless steel Decora front plates.
The DD-BN40’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. Built to last.
