CONNECTING THE PREAMPLIFIER
AUDIO CONNECTIONS
Input connections are made using female XLR connectors. These are wired with pin 2 positive, pin 3 negative and pin 1 ground. 48V phantom power, if used, is supplied on pins 2 and 3.
Output connections are made using male XLR connectors or RCA phono jacks. The XLR connectors are wired with pin 2 positive, pin 3 negative and pin 1 ground. Use the RCA phono jacks for unbalanced output. If the XLR outputs are to be used unbalanced, a modified cable is required and pin 3 should be left open. See figure 2 below. The XLR and the RCA outputs can be used simultaneously.

POWER SUPPLY CONNECTIONS
A four pin XLR connector is used for the DC power input of the V2. The V2 can be ordered to operate from either 6 or 12 Volt power sources. Pins 1 and 2 are ground and pins 3 and 4 are either 6 or 12V DC. To avoid compatibility problems it is recommended that 6 Volt systems be wired to use pin 3 for hot (+6v) and pin 2 for ground while 12 Volt systems should be wired to use pin 4 for hot (+12v) and pin 1 for ground. The V2 current draw ranges from .38A to .62A depending on the microphone used.
