The DD-BN31 is a complete wall-mounted Dante audio network interface. It features two XLRmic 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 DD-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-channelmono. Each rear-panel output provides a switch to set the output to balanced professional or unbalanced consumer level. The DD-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 DD-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 dynamicmic 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 digitalaudiolevel of -18 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 channels.
Two Dante audiochannels are converted to unbalanced linelevel to feed the front-panel Mini-jack. Each channel provides -10 dBVunbalanced for a network digitalaudiolevel of -18 dBFS. The left and right Mini-jackchannels 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 installed.
Two Dante audiochannels are converted to balancedline level on the rear-panel detachable terminal block. Each output provides +4 dBubalanced for a network digitalaudiolevel of -18 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 DD-BN31. AMS audio connectors include RCA, Mini and XLR jacks. The output plate may be located together with the DD-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 DD-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 DD-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. Built to last.
