to 0dBFs
Features selectable digital audio system bits (professional or consumer)
Has AES/EBU and AES-ID3 transformer coupled outputs
The 6420N is 12VDC fed and is housed in a DigiTOOLS enclosure.
3.4 Recommendations for Achieving the Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position your
Kramer 6410N/6420N away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

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 following1:
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
set2
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 unit3.
1 Switch OFF the power on each device before connecting it to your 6410N. After connecting your 6410N, switch on its
power and then switch on the power on each device
2 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
3 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

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 following1:
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)
Connect the AES/EBU detachable terminal block output connector2 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-Recorder3)
Connect the OPTICAL output connector to an optical acceptor (for
example, a DAT-Recorder3)
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 unit4
1 Switch OFF the power on each device before connecting it to your 6420N. After connecting your 6420N, switch on its
power and then switch on the power on each device
2 Using a shielded twisted pair cable (110)
3 A small-sized consumer DAT-Recorder
4 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
