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.

5 Using the Audio Converters
Always switch off the power to each device before connecting it to your
6410N, 6420N. After connecting your 6410N, 6420N, connect its
power and then switch on the power to each device.
Sections 5.1 and 5.2 describe how to connect the 6410N Digital to Analog Audio
Converter and the 6420N Analog to Digital Audio Converter, respectively.
5.1 Connecting the 6410N Digital to Analog Audio
Converter
To connect your 6410N Digital to Analog Audio Converter, as illustrated in the
example in Figure 6, do the following:
1. Connect up to four sources to the four digital input connectors, as follows:
Connect an AES-75source (for example, a DAT-Player) to the
AES-75BNC input connector
Connect an AES/EBU source (for example, a DAT-Player) to the
AES/EBU detachable terminal block input connector using a shielded
twisted pair cable
Connect an S/PDIF source (for example, a DVD Player) to the S/PDIF
RCA input connector
Connect an optical source (for example, a CD Player) to the optical
input connector
2. Connect up to two analog acceptors, as follows:
Connect the ANALOG OUT LEFT and RIGHT detachable terminal
block connectors via shielded twisted pair cables to an analog
balanced stereo acceptor (for example, an amplifier with a pair of
loudspeakers)
If required, connect the PHONES 3.5mm output jack to a headphone
set
The headphone output is usually used for diagnostics and setup of the audio
system. It is recommended to disconnect the headphones (or to minimize the
headphone volume level) when not in use.

6410N, 6420N - Using the Audio Converters
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 6).
4. Set the conversion ratio on the underside of the unit.
It is essential that you choose the correct conversion ratio to prevent clipping, and to
maintain the S/N ratio within the spec limits. The selection of the conversion rate greatly
depends on the type of audio played, and also on the audio equipment that is
connected to the 6410N.
Figure 6: Connecting the 6410N Digital to Analog Audio Converter
5.1.1 Using the INPUT SELECTOR Switches
Set the digital input standard by pushing in and/or releasing one or both of the two
INPUT SELECTOR switches (item 7 (button A) and item 8 (button B), in Figure 2)
on the 6410N Digital to Analog Audio Converter.

5.2 Connecting the 6420N Analog to Digital Audio
Converter
To connect your 6420N Analog to Digital Audio Converter, as illustrated in the
example in Figure 7, do the following:
1. Connect an analog balanced stereo source (for example, a balanced audio
tape player) to the ANALOG INPUT LEFT and RIGHT detachable terminal
block connector connectors via shielded twisted pair cables.
2. Connect the four different digital output connectors to up to four acceptors,
as follows:
Connect the AES-75BNC output connector to an AES-75acceptor
(for example, a DAT-Recorder)
Using a 110shielded twisted pair cable, connect the AES/EBU
detachable terminal block output connector to an AES/EBU acceptor
(for example, a DAT-Recorder)
Connect the S/PDIF RCA output connector to an S/PDIF acceptor (for
example, a DAT-Recorder)
Connect the OPTICAL output connector to an optical acceptor (for
example, a DAT-Recorder)
3. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 7).
4. Set the MODE SELECTOR dipswitches on the 6420N Analog to Digital
Audio Converter to determine the appropriate digital sampling frequency.
5. On the machine underside:
If required, set the switch to PROFESSIONAL or CONSUMER to
determine the digital audio standard format
Set the conversion ratio on the underside of the unit
It is essential that you choose the correct conversion rate to prevent clipping and
to maintain the S/N ratio within the spec limits. The selection of the conversion
rate greatly depends on the type of audio played, and also on the audio
equipment that is connected to the 6420N.
