The DDS-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 DDS-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 DDS-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 DDS-BN40 is PoE powered, and is available in multiple finishes with optional customized graphics.
