2 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 http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the 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 6410N, 6420N away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

3 Overview
Both the 6410N Digital to Analog Audio Converter and the 6420N Analog to Digital
Audio Converter use digital audio transmission standards, as Section 3.1
describes.
This section summarizes the:
Digital and audio outputs on the 6410N and 6420N (see Section 3.1)
6410N (see Section 3.2)
6420N (see Section 3.3)
3.1 Digital Audio Inputs/Outputs on the 6410N and 6420N
Figure 1 illustrates the transmission standards for professional and consumer
formats, which can be translated via the 6410N/6420N.
Figure 1: Professional and Consumer Inputs/Outputs on the 6410N / 6420N
3.2 About the 6410N
The 6410N is a high performance format converter for digital audio signals. It
converts AES/EBU, AES-ID3, S/PDIF or Toslink® optical digital audio signals
simultaneously to:
As Figure 6 illustrates, the sound is output from both the amplifier and the headphones
simultaneously.
