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. 10 MY8-LAKE Owner’s Manual  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. Mesa 8 8 MY8-LAKE Insert Out Insert In ST/MIX/MATRIX ST/MIX/MATRIX Out 8 Crossover Amplifier 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. Contour 4 8 MY8-LAKE Out ST/MIX Insert In MIX/MATRIX Out 8 Amplifier MY8-LAKE Owner’s Manual 11  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. 12 MY8-LAKE Owner’s Manual 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  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. Starting the Lake Controller To start the Lake Controller with an online MY8-LAKE card connected for the first time, follow the steps below. 1. Double-tap (click) the Lake Controller icon on the Windows desktop. 3. Tap [No] if prompted to recall the last system configuration.

For host devices unrecognized by the MY8-AE96 (such as DIO8), you will need to change the emulation mode of the card to MY8-AT by tapping the [Operation Mode] magnifying glass icon at the bottom left of the I/O Config screen in the Lake Controller. For detailed information on the emulation mode settings, refer to the Yamaha Pro Audio website at: http://www.yamahaproaudio.com/ Has the signal been correctly patched to and from the host device? Check the I/O patching on the console to and from the corresponding MY8-LAKE slot. Has the signal been connected correctly in the input router and module input mixer? Verify the input router and input mixer connectivity in the I/O Config screen on the Lake Controller. Has the signal been correctly routed to the outputs via the Output Configuration screen? Verify that the module output is correctly connected to the required host return or AES output on the Output Configuration screen on the Lake Controller. Are all mute points in the MY8-LAKE signal path unmuted? Check that all Input Router, module Input and module Output Mutes are properly unmuted. Unusual Sound (noise, interruption, or distortion) Is the FAULT LED of the MY8-LAKE illuminated? A fault could indicate a signal clip or slipping clock. Is the signal clipping at any point in the signal path? Check input and output levels on the host device and on the Lake Controller software to ensure that the signal is not clipping at any point during the signal path. Is the digital clock slipping? Check the FAULT LED or view “Digital Clock” at top left of the I/O Config screen in the Lake Controller software to check for any digital clocking problems. Network Control or Communication Problems Is the MY8-LAKE card correctly installed and the host device switched on? Check to ensure that the STATUS LED on the card flashes. Is the Windows firewall enabled? Ensure that the Lake Controller is allowed full access through the Windows firewall. Refer to the Lake Controller Operation Manual for further details. Is the Lake Controller PC connected via a Wireless Access Point? Connect directly from your Windows PC to the MY8LAKE card using a Cat5/Cat6 Ethernet cable, and then add a wireless access point once wired connection has proven successful. MY8-LAKE Owner’s Manual 25  Network Control or Communication Problems Is the IP address on your PC correctly configured? 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 use another fixed IP address, such as 192.168.0.x. Are any Dante-enabled devices present on the network? Additional network hardware configuration may be required; refer to the Lake Network Configuration Guide. * If any specific problem should persist, please contact your Yamaha dealer. 26 MY8-LAKE Owner’s Manual  Specifications General Specifications Sampling Frequency Mini-YGDAI I/F AES/EBU Input/Output 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz Internal Operating Frequency 96 kHz Signal Delay Best case (synchronous 96 kHz to synchronous 96 kHz) from AES input to AES output via module (Contour or Mesa) 0.7185 ms Power Requirements maximum 3W Temperature range Operating 0 to 40 °C (32 to 104 °F) Storage -20 to 60 °C (-4 to 140 °F) I/O Characteristics 30 Terminal name Format Data length Sampling Frequency Level Connector AES/EBU (In/Out Ch 1-8) AES/EBU 24 bit 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz (I/O individually selectable per Ch) RS422 D-sub 25 pin NETWORK (Ethernet) 10Base-T/ 100Base-T - - - RJ-45 MY8-LAKE Owner’s Manual  Connector Pin Assignment 13 AES/EBU Signal Pin 1 14 25 Input Ch 1–2 3–4 5–6 Output Ch 7–8 1–2 3–4 5–6 7–8 Hot 1 2 3 4 5 6 7 8 Cold 14 15 16 17 18 19 20 21 Open GND 9, 11 10, 12, 13, 22, 23, 24, 25 176.1 (12) 164.1 Dimensions 40 120 Unit: mm * Specifications and descriptions in this owner’s manual are for information purposes only.
