INSTALLATION
The DPS II may be used in a wide variety of applications and environments. In a
rack-mountable, all-steel enclosure, the unit is designed for continuous professional
use. Mounting location is not critical. However, for greater reliability we recommend
that you not place the units on top of power amps or other sources of heat. The tube
circuitry needs about a minute to “warm up” from a cold power up.
AC Power Hookup
The DPS II has an internal power supply designed to operate at 115 VAC @ 50 to 60
Hz. Units manufactured for use outside the United States of America have been
modified to comply with the required electrical specifications.
Analog Audio Connections
Audio connections to and from the DPS II are balanced XLR (Pin 2 = Hot (+), Pin 3 =
Cold (-), Pin 1 = Ground) and unbalanced ¼” (Tip = Hot (+), Sleeve = Ground). We
recommend that you switch off the +48V Phantom Power whenever changing
connections to the XLR input. The front mounted jacks can act as both a balanced XLR
connection, and an unbalanced ¼” connection.
