4. EIGHT CHANNEL HIGH PERFORMANCE MICROPHONE SPLITTER User Manual MIC LINE SPLITTER SX XLR IN 16X XLR OUT Taking care of your ProSplit 8 Use the ProSplit 8 to split eight balanced low impedance microphone signals into sixteen balanced low impe dance microphone signals eight pairs Each channel of the ProSplit 8 provides one direct output and one transformer isolated output from a single microphone Applications include sending the direct outputs to the main or FOH Front Of House mixer and the second isolated outputs being sent to a monitor or recording mixer The direct outputs pass phantom power from the main mixer to the microphones for use with condenser microphones SPECIFICATIONS NOTE All measurements made from TRANSFORMER ISOLATED MICROPHONE OUTPUT with PAD SWITCH out off and 150 Ohm balanced source feeding MI The ProSplit 8 includes a ground lif switch on each isolated output to reduce noise due to ground loops between connected equipment For versatility the Pro Split 8 also features an attenuator pad switch on each input that can be used to connect preamplitied signals to the two microphone level ProSplit 8 outputs on each channel Typically preamplified signals would originate from instrument preamplifiers mixers keyboards etc Rack mounting ears are reversible for flexibility in sy stem cabling The 19 1U black all steel case and its all passive design allow the ProSplit 8 to provide years of
