6.2 Cascading SDI-AES De-Embedder / SDI-AES Embedder Units
You can cascade up to four interconnected 6809 SDI-AES Embedder units
with up to four interconnected 6808 SDI-AES De-Embedder units 1 to provide
eight streams of AES, each stream containing two digital audio channels (see
Figure 6 and Figure 7).
To cascade four
6809 and four 6808 units, do the following:
1. Connect up to 16 analog audio sources to the analog inputs on an AES
Audio Router (A/D), and connect each of the eight AES outputs 2 .
2. Connect an SDI source to the SDI IN BNC connector on the 6809 unit # 1
and interconnect 3 the four 6809 units.
3. Connect the SDI OUT BNC connector on 6809 unit # 4 to the SDI IN
BNC connector on 6808 unit # 1, and interconnect 4 the four 6808 units.
4. Connect the two AES OUTPUT BNC connectors on each 6808 unit 5 .
5. On each 6809 / 6808 unit, set the GROUP SELECT dipswitches to
choose the audio group (see section 5.2.1).
6. On each 6809 / 6808 unit, connect a 12V DC power adapter to the power
socket and connect the adapter to the mains electricity 6 .
1 Using a single coax cable (SDI + AES) with a transmission of up to 300m
2 Connect the AES OUTPUT 1 to the AES INPUT A BNC connector, and the AES OUTPUT 2 to the AES INPUT B BNC
connector (6809 unit # 1). Connect the AES OUTPUT 3 to the AES INPUT A BNC connector, and the AES OUTPUT 4 to
the AES INPUT B BNC connector (6809 unit # 2). Connect the AES OUTPUT 5 to the AES INPUT A BNC connector, and
the AES OUTPUT 6 to the AES INPUT B BNC connector (6809 unit # 3). Connect the AES OUTPUT 7 to the AES INPUT
A BNC connector, and the AES OUTPUT 8 to the AES INPUT B BNC connector (6809 unit # 4)
3 Connect the SDI OUT BNC connector on unit # 1 to the SDI IN BNC connector on unit # 2; connect the SDI OUT BNC
connector on unit # 2 to the SDI IN BNC connector on unit # 3; and connect the SDI OUT BNC connector on unit # 3 to the
SDI IN BNC connector on unit # 4
4 Connect the SDI LOOP BNC connector on unit # 1 to the SDI IN BNC connector on unit # 2; connect the SDI LOOP BNC
connector on unit # 2 to the SDI IN BNC connector on unit # 3; and connect the SDI LOOP BNC connector on unit # 3 to the
SDI IN BNC connector on unit # 4
5 On 6808 unit # 1, connect the AES OUTPUT A BNC connector to the AES stream 1, and the AES OUTPUT B BNC
connector to the AES stream 2. On 6808 unit # 2,connect the AES OUTPUT A BNC connector to the AES stream 3, and the
AES OUTPUT B BNC connector to the AES stream 4. On 6808 unit # 3, connect the AES OUTPUT A BNC connector to the
AES stream 5, and the AES OUTPUT B BNC connector to the AES stream 6. On 6808 unit # 4, connect the AES OUTPUT
A BNC connector to the AES stream 7, and the AES OUTPUT B BNC connector to the AES stream 8
6 As an option, you can purchase the Kramer VA-50P 6 Port Universal 12-Volt Power Supply, enabling you to supply power
to up to 6 Kramer devices that require 12VDC
