INTRODUCTION
Thank you for your purchase of
the DB 25b, a passive direct box
designed to take high impedance
signals and convert them to low
impedance. The unit features an
Attenuator volume control for the
input signal, and a Ground Lift
switch which may reduce
unwanted hum caused by "ground
loops".

DESCRIPTION
Input Jacks: 1/4" unbalanced
jacks for receiving line or
instrument level signals.
Attenuator: Reduces the input
signal by the amount indicated.
Ground Lift Switch: In the "Lift"
position, the ground connection of
the XLR jack is disconnected from
the chassis.
Output Jack: XLR balanced jack
for connection to a mixing board
or other balanced input device.
