12. Signal fl ow and processing
12.1. Signal fl ow
The fi gure below depicts the audio signal fl ow for a D Series Lake device. It is worth noting that this sophisticated
device provides seven points in the signal chain where the signal level can be adjusted, muted or disconnected.
Figure 12.1: D Series Lake Signal Flow Diagram

The input section (inputs, input router and input mixer) allows for mixing capabilities as well as redundant and
prioritized inputs with automatic switch-over in case of signal failure
2
Up to four Lake Processing modules provide user EQ and loudspeaker processing, including LimiterMax limiting
3
The Output router allows free routing between module outputs and power output channels
4
Each power output channel provides individual channel processing, including ISVPL limiter, RPM and
load monitoring

12.2. Level Adjustments & Mute Points
The following points in the signal fl ow can adjust level or mute the signal:
1 Input Router Stage Input selection and MUTE
2 Input Mixer Stage Router on /off connection to mixer and gain settings
3 Module Input Stage Mute and gain settings
4 Module Output Stage Mute and gain settings
5 Output Router Stage Output on /off routing connections
6 Attenuation Stage Power output channel mute and attenuation settings
7 Amp Gain Stage Amplifi er gain control
NOTE: If the required audio signal is not passing correctly, verify the connection, mute and gain settings
at all seven stages.

13. System confi gration tutorial
This section will describe how to get started with associated software and set up a basic system for operation.
13.1. Network setup
13.1.1. Network connections/topology
Each frame has two network ports; a primary and a secondary. See the below diagram for a typical network
topology using the primary ports.
By default, the secondary ports are confi gured in dual redundancy mode to support a second redundant network.
The alternate confi guration for the two ports is a switch mode which allows daisy–chaining devices in a single
network. Daisy chain mode is not recommended for more than a few devices, and for not more than two if running
Dante audio along with control data.
NOTE: If using Dante audio in the network, the audio traffi c needs to be fi ltered from reaching the
wireless links.
13.1.2. Network confi guration
Frames are confi gured by default to obtain IP addresses automatically. The frame will assign itself an IP address
in the link local range (169.254.1.0 through 169.254.254.255). If a computer is confi gured the same way
(which should be default on modern operating systems), it will reside in the same subnet as the devices and
communication can be established. Alternate confi gurations would be DHCP for a managed network or fi xed IP.
To connect to the secondary network in dual redundancy mode the computer shall be confi gured with an IP
address in the 172.31.0.0 – 172.31.255.255.
