IEC Power Cord Receptacle
This is the power cord receptacle of the ProVocal™. An IEC cord is included with the shipped
product.
S/PDIF Digital Output Connector
The ProVocal™ provides S/PDIF digital output formatting through the RCA coaxial connector.
Be sure to use short lengths of 75Ω digital cables or 75Ω video cables rather than standard audio
RCA to RCA cables. Using the correct cables will prevent digital dropouts and other interconnection problems.
MIDI In
This is the input connection for MIDI output devices.
Analog Input Connectors
The analog input section of the ProVocal™ offers both front panel XLR (Microphone) and 1/4”
TS (instrument) rear-panel 1/4" TRS (Line) electronically balanced connections. The 1/4” connector may be used in a balanced or unbalanced configuration. Using a 1/4” TS connector will
unbalance the signal.
Analog Output Connectors
The analog output section of the ProVocal™ offers both XLR and 1/4" TRS electronically balanced connections. The 1/4” connector may be used in a balanced or unbalanced configuration. Using a 1/4” TS connector will unbalance the signal.
Line Input
This balanced high-impedance input connection is used to insert an instrument signal directly
into the preamp. Use the LINE switch to make instrument input or the rear panel line input
active. Plugging into the instrument jack will override the rear panel 1/4” input jack (line input
must be selected).
