Yamaha MY4-AD: Four-Channel Analog-to-Digital Input Card

The Yamaha MY4-AD is an optional analog-to-digital input card crafted to extend the capabilities of compatible Yamaha digital mixing consoles and signal processors. Designed for professionals who demand reliable, high-quality conversion in live sound, installation, and broadcasting environments, this four-channel card provides clean, balanced analog inputs that feed directly into your digital workflow. With four independent channels, the MY4-AD helps you capture performances, instruments, and line-level sources with minimal latency and consistent sonic integrity, all while preserving the intuitive, familiar Yamaha control surface you rely on day after day. Whether you’re layering additional stage inputs for a multi-band live show, expanding a conferencing system, or feeding backline signals into a matrix, the MY4-AD is a flexible, drop-in solution that blends seamlessly with existing gear.

• Four analog inputs via balanced XLR3-31 connectors — four high-quality, balanced inputs provide clean signal capture with excellent common-mode rejection, reducing hum and interference in challenging live or installed environments.
• Compatibility with Yamaha digital mixers and signal processors — designed to slot into compatible Yamaha ecosystems, enabling straightforward routing, management, and synchronization with your existing consoles and processors.
• Compact, rugged form factor — a slim expansion card that fits into standard Yamaha chassis slots without adding bulk, measuring 120mm x 40mm x 176mm (4.7" x 1.6" x 6.9"), built to withstand the rigors of touring and daily use.
• High headroom input capability — maximum input level before clipping is +24 dBu, providing ample dynamic range for most professional line-level sources and reducing the risk of distortion during loud performances or busy mixes.
• Easy installation and maintenance — designed for straightforward installation into compatible equipment, with minimal power draw and simple field replacement whenever upgrades or repairs are needed.

How to Install Yamaha AD Card

Installing the MY4-AD is a straightforward process that integrates into your existing Yamaha setup with minimal downtime. Follow these practical steps to ensure a secure, reliable installation and optimal performance from your new four-channel analog-to-digital input card:

• Power down and disconnect — turn off the Yamaha console or processor and unplug from the power source to prevent any risk of electrostatic discharge or component damage during installation.
• Locate a compatible expansion slot — identify an available expansion slot within the chassis that supports Yamaha input cards. Refer to your model’s manual for slot compatibility and maximum supported configurations.
• Remove the slot cover if required — if the slot is covered, carefully remove the cover plate or any mounting hardware as specified by the device’s service manual.
• Insert the MY4-AD — align the card with the slot and gently slide it in until it seats securely. Ensure the connectors are fully engaged and the card is firmly supported by the chassis.
• Secure and reconnect — fasten any screws or latching mechanisms to hold the card in place, then reattach the chassis cover and reconnect power and peripherals.
• Power up and configure — power on the console and access the input or routing settings. Enable the MY4-AD as an active input card and assign each of the four XLR inputs to the desired channel paths or submixes.
• Connect analog sources — route your microphones, instruments, or line-level devices to the four balanced XLR inputs on the card. Use proper gain staging to maximize signal-to-noise ratio while avoiding clipping.
• Calibrate and test — verify signal integrity, check for phase alignment if needed, and perform a quick test to confirm that each channel is delivering clean digital feeds to the mixer or processor.
• Document the configuration — record the card’s slot location, channel assignments, and any routing changes to simplify troubleshooting and future upgrades.
