Power
Phantom Power The VP88 can operate on an internal 6V battery or phantom power from any microphone mixer or console
providing 9 to 52 Vdc, or by a phantom power supply such as the Shure PS1A. Each balanced audio cable pair (pins 2 and 3:
Mid/Left; pins 4 and 5: Side/Right) carries the supply current to the microphone, and the cable shield (pin 1) is the ground re-
turn. The Mid or Side output can be used individually with either phantom or battery power. When operating in the Stereo mode
without battery, both Mid/Left and Side/Right outputs must be phantom powered.
Battery Power
If phantom power is not available, move the Battery switch to the Batt On position. The adjacent LED will flash indicating at
least five hours of useful battery life, and if no flashing is observed the battery should be replaced. The battery does not drain
when phantom power is applied.
Installing and Replacing the Battery
The VP88 uses a 6V cylindrical battery commonly used in cameras. Average battery life depends on the type of battery: typi-
cally 70 hours for silver oxide/lithium and 40 hours for alkaline.
