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 noise- levels (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 unit

2

.

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 following

1

:

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

2

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

3

.

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 following

1

:

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 connector

2 an AES/EBU acceptor (for example, a DAT-Recorder)

to

Connect the S/PDIF RCA output connector to an S/PDIF acceptor (for example, a DAT-Recorder

3

)

Connect the OPTICAL output connector to an optical acceptor (for example, a DAT-Recorder

3

)

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

4

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
