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 -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 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 DDS-BN40. AMS audio connectors include RCA, Mini and XLR jacks. The output plate may be located together with the DDS-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 DDS-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 dual powder-coated or stainless steel Decora front plates.
The DDS-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.
