GDC AE-6703 AES67 CONVERTER USER MANUAL
1. FUNCTIONAL OVERVIEW
1 FUNCTIONAL OVERVIEW
The GDC AE-6703 is a bidirectional converter capable of converting 32 channels of audio in each direction
concurrently (total of 64 channel processing). It allows 32 channels of AES3 audio input to be transmitted as
AES67 network audio while at the same time allowing another 32 channels of AES67 network audio input to be
output as AES3 audio.
The AE-6703 AES67 Converter operates in the multicast mode based on the AES67 standard which is
compatible with Dante®, so it can communicate with related devices. The AE-6703 can be configured according
to the user’s requirements via the supplied software application. The external interface of the device is AES3,
which is used to connect AES3 input and output devices.

5.1 Front Panel
Figure 3: AE-6703 Front Panel Indicators
①→ 32-Channel Audio Signal Indicator
From left to right are the 1 to 32 channel audio signal indications, indicating whether the channel
has audio signal input or output. By default, the factory setting is output indication. For more details
on modifying the audio signal indicators, please refer to Section 13.2.
②→Operating Status Indicator (Power)
After the device self-test is normal, the light keeps flashing, indicating that the device is running
normally.
③→Audio Data Reception Indicator (AES67)
After the receive route is configured, this indicator lights up, indicating that the received audio data
from AES67 is normal.
④→ Error Indicator (!)
When the device is operating normally, this indicator is not lit. It is lit whenever an error occurs.
⑤→Input Status Indicator (IN)
This indicator is lit when the audio signal light is configured for AES3 input indication.
⑥→Output Status Indicator (OUT)
This indicator is lit when the audio signal light is configured for AES3 output indication.
⑦→Debug Serial Port
It is only used for engineering debugging and not used during normal operation.

①→DC 12V Power Interface (positive inside and negative outside)
For safety, use only the supplied power adapter.
②→Network Interface AES67(A）and AES67(B)
When connecting a switch, users can only use one of the interfaces and cannot connect two interfaces to
the same switch.
③→Four sets of AES3 Input Interfaces (Input)
The interface is in the form of RJ-45 and each interface corresponds to eight input channels. There is an
indicator light on each side of the interface. The left light indicates whether the first four channels have
input signals and the right light indicates whether the last four channels have input signals. As long as any
one of them has a signal, the corresponding indicator light will light up.
④→Four sets of AES3 Output Interfaces (Output)
The form and indicator light distribution of the output interface are the same as those of the input
interface. When the indicator at the corresponding position is lit, it means that the corresponding four
channels have output signals.

6. ETHERNET/ AES3 WIRE CONNECTION
6 ETHERNET/ AES3 WIRE CONNECTION
▪Network Connection: AES6703 uses a standard gigabit network interface. Please use a Gigabit Switch and
a network cable to connect the equipment, please refer to T568B for the interface standard.
▪AES3 Digital Connection: When AE-6703 is connected to AES3 input/output device, use a good quality
shielded Category 6 network cable. The interface standard is T568B and the corresponding relationship
between the four pairs and the channel is as follows:
▪Pair 1 corresponds to channel 1-2
▪Pair 2 corresponds to channel 3-4
▪Pair 3 corresponds to channel 5-6
▪Pair 4 corresponds to channel 7-8
NOTE: For details regarding the AES3 connections on the SR-1000 Extreme -24 IMB; please refer to the ‘GDC
SR-1000 Installation Manual’.
