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.
To check for up-to-date user manuals, application programs, and if firmware upgrades are
available (where appropriate):
•For DSP-62-AEC, go to www.kramerav.com/downloads/DSP-62-AEC.
•For DSP-62-UC, go to www.kramerav.com/downloads/DSP-62-UC.
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 device 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, 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.
Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce
the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected
and recycled. To comply with the WEEE Directive, Kramer Electronics has made
arrangements with the European Advanced Recycling Network (EARN) and will cover any
costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on
arrival at the EARN facility. For details of Kramer’s recycling arrangements in your particular
country go to our recycling pages at www.kramerav.com/il/quality/environment.
Overview of DSP-62-AEC, DSP-62-UC
Congratulations on purchasing your Kramer Digital Sound Processor (DSP).
DSP-62-AEC, DSP-62-UC are members of the Kramer XSPerience family. They are
advanced, professional 6x2 audio matrix switchers with multi-channel DSP. While both
devices feature AEC (Acoustic Echo Cancellation), HDMI™de-embedding, and class
compliant USB audio interface. DSP-62-UC (Unified Communication) includes all the
DSP-62-AEC features and in addition has auto switching and HDBT2.0 output that can route,
mix, process and distribute all input channels to all output channels.
Most of the information included in this user manual is relevant to both DSP-62-AEC and to
DSP-62-UC. Sections referring to HDBT are not relevant to DSP-62-AEC.
Unless specified otherwise, DSP-62 is used throughout this user manual to refer to both
devices.
Exceptional Quality
•Advanced Audio Matrix Switcher –Professional, studio grade signal conversion
technology.
•Teleconference Optimized –Features AEC that prevents the microphone from picking
up the far-end echoed speech, so you only share the audio spoken directly into the
microphone.
•Max. Video Resolution:
▪DSP-62-AEC 4K@60Hz (4:4:4) HDMI.
▪DSP-62-UC 4K@60Hz (4:2:0) HDBT.
•Audio de-embedding –De-embeds the audio signal from the HDMI input for routing to
any of the outputs.

Kramer Electronics Ltd.
DSP-62-AEC, DSP-62-UC –Introduction

•Programmable –Supports up to 10 global presets, 10 mixer snapshot presets, and 10
mixer presets for each system preset.
•HDMI Support –HDR, CEC, 3D, Deep Color, x.v.Color™, 7.1 PCM, Dolby TrueHD,
DTS–HD.
Advanced and User-friendly Operation
•Wide Range of I/O Formats –Includes 2 HDMI inputs, 1 unbalanced stereo analog input
and 4 balanced analog audio inputs, 2 balanced analog audio outputs, 1 HDMI output, 1
HDBT output (DSP-62-UC only).
•1 bi-directional USB plug and play (PnP) audio port. In addition to AUDIO IN/OUT, as a
result of HDBT, users can use the USB to connect a mouse, webcam, USB flash drive,
or any other USB device to the TX-590RX (for example) side and take control of the PC
that is connected to the DSP-62-UC.
•Reliable PoE (Power over Ethernet) Powering –Accepts power from a remote PoE
provider with optional mains powering from connected power adapter.
•Multi-Channel Processing –Provides DSP that enables simultaneous processing of all
input and output signals.
•Easy Installation –Compact DemiTOOLS® fan-less enclosure for surface mounting,
side-by-side mounting of 2 devices in a 1U rack space with the recommended rack
adapter or fit in a Kramer T-BUS.
•Easy, Cost-Effective Maintenance –LED indicators for main power, line in/out, mic in,
clipping, and HDMI input selection, enable easy local maintenance and troubleshooting.
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 for each input; execute
routing and select line in, mic in, phantom power or line out on each port; configure
master level, and more. Users can 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.
