Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Review the contents of this user manual.
Go to www.kramerav.com/downloads/DSP-62-AEC to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving Best Performance
•Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interference from neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer DSP-62-AEC away from moisture, excessive sunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please refer to the permitted rating
for an external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cord that is supplied with the unit.
•Disconnect the power and unplug the unit from the wall before installing.
•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified
personnel only.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which is located on the bottom of the unit.

Local firmware upgrade via the RS-232 port ensures lasting, field-proven deployment.
•Intuitive and Comprehensive Configuration and Control –Via a powerful, user-friendly
graphic interface, set volume (gain and attenuation) and DSP per input; execute routing
and select line in, mic in, phantom power or line out on each port; configure master level
and more. Control signal routing, volume and other basic settings using API commands
via RS-232 communication transmitted by a PC, touch screen system or other serial
controller.
