11.7.2. AES67
When the device is in AES67 enable mode, the device is in 48 kHz only (also for Dante 
subscriptions/transmissions). The receiver latency for AES67 subscriptions is 2 ms. Transmission flows are 
Multicast only. 
AES67 subscriptions can only be configured in Dante Controller. The AES67 transmitter must support the SAP 
(Session Announcement Protocol). This is one of four device discovery methods referenced in the AES67 
standard. Check if the transmitting non-Dante AES67 device supports SAP. Otherwise Dante Controller cannot 
discover the audio flows coming from the device. Dante devices support SAP if their AES67 mode is enabled. 
Multicast IP addresses must be in the range of 239.69.0.0 - 239.69.255.255. If dual redundancy is enabled on 
the device, the AES67 flow only works on the primary network. It is still possible to utilize Dante on primary and 
secondary networks at the same time, as an AES67 flow is present on the primary. 
12. Lake Processing and Lake Controller 
12.1. Introduction 
D Series Lake integrates seamlessly into the Lake Processing environment, providing all features, functionality and 
connectivity associated with all Lake Processors. The internal Lake Processing, which includes programmable 
crossovers, EQ, dynamics and other functions, is fully controllable via Lake Controller software with a version 
number of v6.3 for D 200:4L, D 120:4L and D 80:4L, v6.5.0 for D 20:4L and D 10:4L and v6.5.1 for D 40:4L. 
All models are compatible with newer versions of the Lake Controller.
both available on www.labgruppen.com. Also, additional documentation is available from the Start Menu after 
software installation. 
12.2. Modules and Frames 
A Frame represents one physical Lake Processor device (e.g. a D 200:4L). A maximum of four Modules are 
contained within each Frame; these are referred to as Module A, B, C and D. The number of Modules shown in a 
ed as a Classic Crossover (Bessel, Butterworth, Linkwitz–Riley), as a Linear Phase 
Contour Classic 1 Way (CL1–Way) Output Modules, providing a total of four Module outputs that can be routed 
to any of the four power outputs, but default is one to one (input 1 -> output 1 etc.). Please refer to the Lake 
Controller Operation Manual for further information.
