Introduction

Congratulations, and thank you for your purchase of

the DOD direct box.  The AC 260,265,275, and 285 all
solve distortion problems normally associated with
using high impedance sources with low impedance
inputs.  The product line begins with the AC 260 which
is a basic easy to use direct box and progresses into
the AC 285 with a cabinet emulator.  The features,
operation, and specifications literature have been indi-
vidualized for each box.  Determine which box you
have and consult the following text until you reach the
section that is specific to your box.

AC 260 Direct Box
Features of the AC 260

• Allows a hi impedance unbalanced source to directly

feed a low impedance balanced input.

• Low distortion
• Low noise 
• Rugged metal chassis 

Operation of the AC 260

• Connect the output of the high impedance source to

the input of the AC260.

• Connect the low impedance output of the AC260 to a

mixing console or other low impedance input.
Connect the unbalanced 1/4” tip-sleeve output to a
high impedance input.
