Product Overview
Specifications
- The Gateway acts as a Milan compliant Ethernet switch, providing 6x Gigabit etherCON™ and 2x Gigabit opticalCON™ connection points to handle incoming and outgoing network signals.
- The rear panel includes XLR connections for 16x AES/EBU digital inputs and outputs or 8x analog audio inputs and outputs. Each XLR can be switched independently to be used for analog or digital signal.
- The Gateway accepts or generates two AVB audio streams enabling digital data (audio, control, etc.) to be sent over the network to the Endpoints. It also digitizes the analog audio (if used) for the same purposes.
- Tree layers of redundancy can be freely defined from all available inputs.
- Each AES/EBU digital input contains an asynchronous sample rate converter allowing to connect up to eight different clock sources to the Gateway.
- 16x DSP channels are available on the Gateway, each offering mute, gain, polarity, delay and EQ.
- All incoming audio can be mixed into the 16x DSP channels as the Gateway functions as a 16 x 16 matrix mixer.
- The DSP outputs can be freely patched to all available outputs.
- The 15 V DC input is used for back-up power in the event of AC power loss. Use only the supplied 15 V DC power supply connected to a secondary power supply.
- Audio Input/Output LEDs on the front panel emit green when the associated rear-panel XLR con-nector is programmed for analog, blue when programmed for digital/AES.
- The front panel of the Gateway features Network activity LEDs for both Primary and Secondary connections.
Connecting the Gateway
The Gateway and other Adamson devices can be connected to the AI software using standard ethernet ca-bling (minimum Cat5e). If the network is used for control only, standard gigabit switches can be used in ad-dition to the switch-ports of the Gateway. A maximum of eight devices can be connected in a daisy-chain.
AVB Milan Audio
Full network connectivity, including AVB audio transport and control requires
AVB enabled switches. Cur-rently Luminex Gigacore Series and Extreme Networks
X-Series switches with AVB license were tested to work with Adamson AVB
systems. As the Gateway includes a Milan enabled switch it can be used for
smaller AVB Milan setups without additional switches.Adamson AVB components
use a fixed presentation time of 2 ms (network latency). From the talker to
the furthest listener in a network chain a maximum of 2 ms latency is allowed.
If the total network latency ex-ceeds 2 ms the audio connection will break.
Each CS-Series cabinet and rack-mounted equipment includes switch fabric and
introduces a fixed latency. An additional latency is introduced by the talker
when creating the stream:
- CS-Series cabinets: 0.26 ms
- Adamson Gateway and Bridge: 0.14 ms
- Creation of Stream on an Adamson Gateway: 0.12 ms
- Gigabit AVB Switch: 0.12 ms
Below is an example calculation for a setup with an Adamson Gateway converting an analog signal to AVB, connected to an NDS using Luminex switches. Six CS7 are connected in daisy-chain to one of the cabinet outputs of the NDS:
- Adamson Gateway (Creation of Stream + Switch) 0.26 ms
- NDS (Gigabit AVB Switch) 0.12 ms
- CS7 0.26 ms
- CS7 0.26 ms
- CS7 0.26 ms
- CS7 0.26 ms
- CS7 0.26 ms
- CS7 0.26 ms
- Total Latency: 1.94 ms
Adamson recommends daisy-chaining a maximum of six cabinets. This number may be reduced, depend-ing on the network setup and resulting additional latency. The total latency can be inspected for each AVB patched endpoint on the diagnose page. AVB audio connections can be patched in the AI software or in a third party application like Hive.
Streaming AVB to the Gateway
To be able to stream AVB Milan audio into the Gateway a dedicated clock leader
needs to be set, as any sending device may act as clock leader in this
situation. To synchronize the clock streams and patch audio connections Hive
needs to be used.
- Select the clock following device in the discovered entities list in Hive.
- In the entity inspector go to “clock_domain”.
- In the “dynamic info” select 3. Primary Clock Input stream 2. (or any other Clock or CRF stream that contains the synchronizing clock).
- In the “Stream Based Connection” view output stream 2 (the stream of the Gateway containing the clock stream) of the leader needs to be patched to input stream 2 of the follower. A valid stream can be identified as a green symbol (primary and secondary connected) with a black dot (valid word clock detected) in the middle.
- Once this is done change Hive to “Channel Based Connection” view and patch the desired audio channels. This is possible in both directions.
Clear User Data
The Gateway can be reset to firmware default settings, either through the AI software on the menu page (allows for multiple devices to be cleared at the same time), or on the diagnose page or by following the power cycle sequence below. Clear user data will clear all user settings (EQ, gain, delay) as well as control and AVB patch.
- Power up the device. The fan will briefly run at full speed before going to idle.
- When the status LED flashes in green once, disconnect power.
- Power up the device. The fan will briefly run at full speed before going to idle.
- When the status LED flashes in green twice, disconnect power.
- Power up the device. The fan will briefly run at full speed before going to idle.
- When the status LED flashes in green three times, disconnect power.
- Power up the device. The fan will run at full speed for a longer period of time than the previous times, at this point the LED flashes orange.
- The factory reset is successful when the status LED continuously turns green.
