Description
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 channels.
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 installed.
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. Built to last.
