Contour/Mesa Configuration Signal Flow
In hybrid mode (Contour/Mesa), the MY8-LAKE provides 2x6 crossover modules and 4x4
system EQ modules as shown in the diagram below.
Frames and Modules
The term “Frame” is used to represent a physical Lake device (e.g., the MY8-LAKE card).
The MY8-LAKE frame can contain two to eight audio processing units referred as “Modules.”
In Mesa mode (default) the MY8-LAKE Frame contains eight modules, labeled as modules
A – H. Each Mesa module provides a single channel of EQ, levels and dynamics processing
and only uses the module type of “Mesa EQ.”
In Contour mode the MY8-LAKE Frame contains up to four modules labeled A – D; in Contour/
Mesa mode there are up to six modules labeled A – F. The number of modules available in a
Contour or Contour/Mesa mode is dependent on the Contour module types in use.
Contour modules can be configured in many different ways, such as 2-, 3-, 4-, 5-, and 6-way
Classic Crossovers (Bessel, Butterworth, Linkwitz-Riley), 2-, 3-, and 4-way Linear Phase
Crossovers, or as full bandwidth Auxiliary Outputs. For a Contour module example, refer to the
section “XOVER Screen” later in the Quick Start Guide.

System Examples
The MY8-LAKE card can be used in a variety of ways; this chapter describes two typical
scenarios.
System EQ (Mesa)
System EQ can be applied in Mesa mode; this is the default configuration for the MY8-LAKE
card. Mesa mode provides eight channels of discrete audio processing that can be assigned
to the host channel Insert Ins from the Insert Outs, without the use of any physical cabling—
thanks to the card solution. This configuration provides powerful Lake EQ and dynamics
processing for use as system EQ (in front-of-house mixes, for example), or as individual input
channel EQ (in vocal processing, for example). If three cards are installed, this powerful,
versatile EQ can be used in up to 24 mixes, which supports any scale of monitor system
equalization. The Mesa modules can also be used for subsystem aligning and tuning,
replacing the host console's Matrix section with an Input Mixer of each module.
Crossover (Contour)
Crossover can be applied in the Contour mode for Lake. The MY8-LAKE provides a 4x12
crossover configuration; the processed channel signals can be routed internally back to the
host device (up to 8 channels), and/or output via the AES/EBU D-sub 25-pin connector (up to 8
channels). In this system example, the stereo main mix signals from the host are routed to the
MY8-LAKE for crossover, EQ, levels and dynamics processing. The processed signals are
sent back to the available channels on the host and/or the AES/EBU connector, then to the
power amplifiers or powered speakers.
The output signals contain only the relevant frequencies (post-crossover) for each amplifier
and speaker. This scenario removes the need for separate outboard crossover and EQ
processing, reducing the amount of external hardware and racks required to achieve the same
result as traditional active speaker crossover systems.

Quick Start Guide
Installation and Cable
Connection
The first thing you should do is to install the
card in your host device. For detailed
installation instructions, refer to the owner's
manual supplied with your host device.
1. Install the MY8-LAKE into an
appropriate slot on your host
device while the power is turned
off, and tighten the two screws
of the card to ensure a secure
connection.
2. Connect a Cat5/Cat6 Ethernet
cable between the MY8-LAKE
and the Windows PC that will be
used for the Lake Controller.
NOTE
•
When using multiple PCs, Lake devices,
or wireless access points, a network
switch is required.
• The default IP Address Config on the
MY8-LAKE is Auto - Zero Conf
(169.254.x.x); if connectivity problems
are encountered, try setting the network
adapter of the PC to the same subnet
range or to another fixed IP address
such as 192.168.0.x.
• If Dante audio networking coexists on
the same network for the other Lake
devices, additional network
configuration will be required.
• For further details about configuring the
Lake Controller network, refer to the
Lake Controller Operation Manual and
Lake Network Configuration Guide.
• To prevent electromagnetic
interference, use an STP (shielded
twisted pair) Ethernet cable.
Lake Controller
Software Installation
To enable full functionality and operation of
the MY8-LAKE, the Lake Controller software
must be installed in your Windows PC.
1. Insert the included USB flash
drive into your Windows PC.
2. Follow the on-screen prompts to
install the software.
We recommend that you check online
for the most recent version of the Lake
Controller.
Console (Host Device)
Settings
Before using the MY8-LAKE, the I/O
patchings on the console (host device)
must be executed according to the specific
mode, as described in the following
examples.
CAUTION
Make sure to mute or move the faders all
the way down when making the console
settings to avoid undesired sound.
Mesa mode: For typical applications for
system EQ or input EQ, you will normally
insert the Lake Processing into insert points
of any input or output channels on the
console. On the INSERT screen of the
console, patch the corresponding channels
of the SLOT for the MY8-LAKE card to the
Insert Outs and Ins of the desired channels
on the console, and make sure the INSERT
buttons are ON.
Contour mode: For typical applications
for crossover processing, the output ports
of the desired ST L/R or MIX channels
should be patched to the corresponding
channels of the SLOT for the MY8-LAKE
MY8-LAKE Owner’s Manual 13
card. The post-crossover signals can be
routed back to the host or out to the AES/
EBU connector. In case of routing back to
the host, patch the corresponding channels
of the SLOT to the Insert In of any empty
output channels. If any input channels are
available instead, you can also patch to the
input ports and directly output the signals
via Direct Out.
NOTE
For details about the console settings, refer to
the owner’s manual supplied with your host
device.

return to the Home screen.
Levels Screen
The Levels screen provides access to
controls for gain, delay, LimiterMax, input
mixer, mutes and polarity adjustments. This
section describes various example
scenarios to highlight key functionality.
1. Tap the [Home] button, then tap
a module icon.
If a submenu is not selected, tapping a
module icon provides a shortcut to the
EQ, Levels and HPF/LPF or XOVER
screens for the selected module.
2. Tap the [Levels] tab at the top
left of the screen (if not already
selected) then tap the red
[Output MUTED] button to
unmute the Mesa module output.
NOTE
Mesa EQ modules do not have a
separate module input mute. Input Router
and Input Mixer mutes and connectivity
can be reviewed by tapping the
associated magnifying glass icon shown
below.
3. Check any associated mute and
level settings in the MY8-LAKE
host device.
Assuming there is an audio signal
passing from the host device into the
module, the screen will look similar to
that shown below after the input has
been unmuted.
MY8-LAKE Owner’s Manual 17
NOTE
The Levels screen always displays active
RMS & Peak metering for the input and
output channels on the selected module.
The fader positions and associated
values change as each level type is
selected (Gain, Delay, LimiterMax etc.).
4. Tap the [LimiterMax] button to
display a submenu containing
additional options for RMS and
peak limiter controls.
NOTE
•
The MaxRMS Level, MaxRMS Corner,
MaxRMS Attack, MaxRMS Release and
MaxPeak Level controls can be used to
set independent peak and RMS output
limiters as required for your application.
• These limiter levels are specified in dB
units. Yamaha presets for Installation
series loudspeakers are tuned
assuming 26 dB amp gain, and the
“Analog Output Reference” in the I/O
Config screen is set to +24 dBu by
default for the MY8-LAKE (which is the
case for most of Yamaha consoles).
However, the limiter levels should be
adjusted according to the specific
output devices, amplifiers and your
particular applications. For use with +18
dBu maximum output devices such as
DM2000, for example, you will need to
change the setting of the Analog Output
Reference.
5. Tap the [LimiterMax EXIT] button
to return to the top level menu.
6. To change polarity, tap the
[Enable Polarity] button, then tap
a polarity button (located to
the right of the associated
channel’s mute button).
7. To label a channel, tap the [Label
Channel] button, then tap a
channel label button. Enter a
new name, then tap [OK] (or
press <Enter>).
NOTE
•
The mute status text is removed from
the mute button and mute functionality
is temporarily disabled.
• The channel number is appended
automatically and does not need to be
included in the text label.
8. Tap the [Label Channel] button
again to exit channel labeling
and enable mute functionality
again.
NOTE
The Meter Options submenu includes
various other metering options and
functionality, some requiring Designer
Mode activation before the functions are
displayed. For further information on
Designer Mode and more detailed Levels
screen functionality, refer to the Lake
Controller Operation Manual.

PEQ & GEQ Overlays
The Lake Controller software provides
powerful EQ overlays that allow layering of
EQ using parametric EQ (PEQ) and fixed-
band graphic EQ style controls (GEQ).
1. Tap the [Home] button, then tap
a module icon.
2. Tap the [EQ] tab at the top of the
screen (if not already selected),
then tap the [PEQ1] tab.
The EQ tab expands to show the HPF/
LPF, PEQ and GEQ tabs.
3. Select a Mesa EQ filter by
tapping the icon highlighted in
orange as illustrated below.
The cursor changes to the same shape
for confirmation.
4. Drag the cursor and tap again
anywhere on the EQ graph in the
main section of the screen.
• Two filter edit boxes appear at the
top of the screen, two corresponding
filter points appear on the 0 dB line
in the middle of the screen, and a
graphical filter editing tool appears
at the bottom of the screen.
• The Mesa EQ filter is a unique filter
that allows separate control of both
sides of the filter allowing for fast
asymmetrical filter creation.
5. Tap and drag one of the red “X”
filter points up or down to boost/
cut.
6. Use the filter edit tool at the
bottom of the screen to adjust
the slopes.
Drag left or right in the numbered
zones to adjust the filter as described
below.

7. Tap the [Filter Edit] button to
adjust filter gain, frequency
center point and slope.
8. Tap any of the blue boxes that
appear at the top left of the
screen to manually enter
specific values if needed.
9. If the [Frequency Lock] button at
the top left of the screen is
orange, tap the button to disable
this function.
NOTE
Frequency Lock is enabled by default
and restricts filter selection and frequency
adjustment by tapping and dragging on
the red ‘X’ filter points. When enabled, this
feature avoids accidental EQ adjustments
requiring selection of PEQ filters by
tapping on the associated filter box at the
top of the screen, and frequency
adjustment is only permitted using the EQ
filter edit tool described in step 6. For
GEQ, this feature forces the user to select
a GEQ filter by dragging the EQ selection
tool at the bottom of the screen.
10. Tap on the [GEQ2] tab at the top
of the screen.
NOTE
The EQ curve from the PEQ1 is visible on
GEQ2; the EQ overlays stack on top of
each other having a compounding effect
on the resulting EQ.
11. Tap on the associated filter point
‘X’ to select a GEQ2 filter that
overlaps the PEQ1 Mesa filter
frequency range.
12. Drag the filter point up or down
to boost/cut.
The GEQ filter affects the overall EQ
curve indicated by the white line (i.e.
the sum of all filters on all PEQ/GEQ
overlays that affect the selected
module).
HPF/LPF Screen
(Mesa mode only)
The HPF/LPF screen provides control of
high- and low-pass filters that affect the
overall EQ on the selected module. Follow
the steps below to set and adjust HPF or
LPF filters on a Mesa module.
1. Tap the [Home] button, then tap
a module icon.
2. Tap the [EQ] tab at the top of the
screen (if necessary), then tap
the [HPF/LPF] tab.
3. Tap the [HPF Enable] and the
[LPF Enable] buttons (so that
they turn orange).
