Your Digital Audio Transcoder
Additionally:
When an input is selected, all the outputs are available simultaneously
All inputs and outputs are capable of receiving and transmitting 24 bit,
192kHz digital audio, including multi-channel audio
A twisted pair input and 2 identical twisted pair outputs are also provided
to support an extensive cascade of branching, providing multiple outputs
over a long distance
The system bit can be set to professional or consumer status, while all the
other system bits remain the same
The 466 Digital Audio Transcoder:
Can transmit the highest quality digital audio over several hundred meters
when several 466 units are used – one as a transmitter and one or more as
receivers
Has transformer coupled AES/EBU and AES-ID3 inputs and outputs
Accepts all serial digital audio transmission standards, compliant with
IEC 60958, S/PDIF, EIAJ CP1201 and AES3 interface standards, as well
as multi-channel standards
Is 12VDC fed and is housed in a DigiTOOLS enclosure
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 that may
adversely influence signal quality
Position your Kramer 466 Digital Audio Transcoder away from moisture,
excessive sunlight and dust
Close the optical cable’s connectors (when not in use) to protect them
against exposure to dirt and dust

Using the Digital Audio Transcoder
4 Using the Digital Audio Transcoder
To connect a single 466 Digital Audio Transcoder machine, as the example in
Figure 3 illustrates1, do the following2:
1. Connect the sources as follows:
Connect a digital audio source (for example, a DAT player) to the
AES-ID3 INPUT BNC connector
Connect a digital audio source (for example, a DVD player) to the
S/PDIF INPUT RCA connector
Connect a digital audio source (for example, a DVD player) to the
OPTICAL INPUT TosLink® connector
Connect an AES/EBU source (for example, a DAT player) to the
AES/EBU detachable terminal block IN connector using a shielded
twisted pair cable
2. Connect the acceptors as follows:
Connect the OPTICAL OUTPUT TosLink® connector to a digital
audio acceptor (for example, an AV receiver)
Connect the S/PDIF OUTPUT RCA connector to a digital audio
acceptor (for example, an AV receiver)
Connect the AES-ID3 OUTPUT BNC connector to a digital audio
acceptor (for example, a DAT recorder)
Connect the AES/EBU detachable terminal block OUT connector
(using a shielded twisted pair cable) to an AES/EBU 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.
4. Release the TWISTED PAIR/LOCAL button to the LOCAL position.
5. Set the MODE SELECT switch button to PROF. or CONSUMER, as
required (see Figure 2).
6. Press one of the LOCAL INPUT SELECTOR buttons to select an input
source3.
This source will appear on all outputs simultaneously.
1 You do not have to connect all inputs and outputs, connect only those that are required
2 Switch OFF the power on each device before connecting it to your 466. After connecting your 466, switch on its power and
then switch on the power on each device
3 If the valid digital audio signal is present on the selected input, the green LINK LED will light

extend the output signal range.
To use additional 466 machines, do the following:
1. Connect the required outputs1 to the newly added 466 receiver unit.
2. Connect the TWISTED PAIR OUT 1 and/or OUT 2 detachable terminal
blocks of the previously connected unit, to the TWISTED PAIR IN
detachable terminal block on the newly added unit, using a shielded
twisted pair cable.
3. Push in the TWISTED PAIR/LOCAL button on the new machine, to the
TWISTED PAIR position2.
4. Set the MODE SELECT switch button on each 466 unit to PROF. or
CONSUMER, as required (see Figure 2)
5. Press one of the LOCAL INPUT SELECTOR buttons to select an input
source3.
This source will appear on all outputs simultaneously
When connecting several machines, push in the TWISTED PAIR/LOCAL button
on all receiver units, except for the transmitter unit.
