11.6.4. Indication
The LoadPilot feature constantly monitors the impedances at the two given pilot tone frequencies and compares to
the measured thresholds. The following faults and warnings can be triggered.
• Speaker shorted warning – Both tones below lower threshold. Corresponds to a distant short circuit that can
either be in the cabling or in the speaker.
• Speaker damaged warning – One of the tones is below or above thresholds. Corresponds to an unexpected
impedance deviation of one of the tones, most likely a damage to the speaker.
• Under speaker count warning – Both tones above upper threshold. Corresponds to an impedance increase
across the impedance response and most likely a loss of speaker(s) in a parallel speaker connection.
•
corresponding to loss of the load.
• Short circuit fault – LoadPilot analysis below short circuit threshold.
11.7. Audio over Ethernet
D Series Lake devices include Dante and AES67 digital audio networking as standard. Utilizing the latest
advances in Ethernet technology, Dante offers simplified system configuration and extremely low latency while
delivering very high quality uncompressed digital audio across the Lake network. The Zen™ automatic configura-
tion feature enables plug-and-play setup without third-party DHCP or DNS servers. Dante is compatible with
high-bandwidth networks, allowing large numbers of audio channels to be distributed alongside control and
analyzer data.
AES67 is a new open standard making it possible connect more devices together and share audio.
The D Series Lake also have a feature to convert between AES67 and Dante, and can accordingly work as a
bridge between the two different network protocols. It can input 8 channels of AES67 and transmit them out
again as 8 Dante channels or vice versa and in any combination of Dante and AES67 channels.
The D Series Lake support 8 x 8 Inputs and Outputs on Dante/AES67. The networked audio channels' inputs are
routed to the Dante receivers and are shared between both Dante and AES67. The total number of networked
audio inputs available is 8 (Dante + AES67).
On the output side, the device has 8 channels in total – and it is possible to configure the channel as Dante only
(Unicast or Multicast) or have it as an AES67 flow as well. Up to 8 channels can be included in an AES67
transmit flow.
In order for the device to be able to input networked audio, “Dante” must be enabled in Lake Controller.
See Lake Controller Operation Manual for further details.
11.7.1. Dante
D Series devices support dual redundant inputs and outputs on Dante, in either 48 or 96 kHz, with receive
latency as low as 0.25 ms and up to 5 ms.
Dante devices and channels can be given “friendly” names, meaning audio can be routed without having to use
or remember complex numbers.
Dante channels can be routed in both Dante Controller or in Lake Controller.
