UNIKA PRO-MMD
UNiKA PRO-MMD is a professional passive DI box designed to drive electronic devices with unbalanced line outputs such as music players, media players, computers, tablets, and phones to professional balanced inputs with low impedance, such as to microphones. e.g. to mixers, external microphone preamps, active speakers and sound cards. Since PRO-MMD is a passive device, no batteries or other power supplies are required.
3 different input connectors: a STEREO mini TRS jack, individual L-R TRS jacks and separate L-R RCA phono jacks. These pairs of inputs cannot be mixed together, so only one source should be connected. All left connections are parallel wired, as are the right connections. This way, the two unused L-R pairs can be used as THRU connectors to route the original signal to a local monitor, headphone amplifier or instrument amplifier.
