This product was designed as a cost effective way of splitting a microphone signal from stage or studio into 2 outputs. One is directly connected and will pass Phantom to ensure that capacitor microphones and DI Boxes will be correctly powered. The other output is transformer coupled, using a high quality miniature device achieving absolute isolation from the main path.
There is a recessed miniature toggle switch to disconnect, or 'lift' - the pin 1 connection to the isolated output - to preclude the possible formation of any hum loops.
The isolated output will block Phantom if this is applied - so no problems will occur, similarly this output can be short circuited with only a minimal drop in level on the main path (0.25dB) - should this happen.
Units sold so far have been used to split microphone signals between FOH (front of house) and monitor mixing desks and also to provide isolated outputs for recording and broadcast use.
They have been purchased by PA Companies, Mobile Recording Engineers and for Theatre shows - with most Customers placing repeat orders!
The rack case is a standard 2U size - but is of very shallow depth - 50mm. It is normally supplied with rack fixing screws - but may be fitted with flat end pieces on request, to act as a free standing "stage box".
