Behringer DI box

If your Microvox is to be connected to a mixer/amp by means of an XLR balanced line input then it must be isolated from the mixer's phantom power. Some mixers have 'global' phantom power which cannot be switched off on individual channels. If the phantom power is required for other devices (mics etc.) then a DI (Direct Inject) box must be used to isolate the Microvox system. The DI box will also convert the signal to balanced line.

The Behringer DI20 is an innovative active 2-channel DI-box/splitter that takes the signal directly from an unbalanced output-such as the Microvox PSUs-and feeds it directly into a mixing console or recorder. The DI20 converts 2 separate unbalanced 1/4" jack inputs into 2 balanced XLR outputs. There is a 2-channel/link mode for flexible usage as mono, 2-channel or splitter box. In link mode, channel 1 can be split up into 2 balanced XLR connectors plus 1 unbalanced 1/4" jack connector. Switchable input attenuation in 3 ranges allows input levels of up to +48 dBu, while a ground lift switch eliminates typical ground loop problems. It operates either by using a 9 V battery or by using 48 V phantom power. The whole package is enclosed in an ultra compact, road-suitable and extremely rugged housing.
