Yamaha DME3 Open Architecture Digital Signal Processor, 8x8 Analog I/O, 24-bit/48kHz, Ethernet Control, 1U Rack

With a dynamic range of 106 dB and ultra-low distortion under 0.05%, the Yamaha DME3 delivers pristine audio processing for installed sound systems. This open-architecture DSP offers 8 balanced XLR inputs and 8 outputs, 24-bit conversion, and a 1U rack-mountable chassis, all controllable via Ethernet, RS-232C, or GPI.

Overview

The DME3 is a professional-grade digital signal processor engineered for conference rooms, auditoriums, and live venues. Its flexible open architecture allows custom audio routing, mixing, and effects using Yamaha's DME Designer software. Two MY-card expansion slots provide additional I/O options, while +48V phantom power on each input accommodates condenser microphones. The unit operates at 44.1 kHz or 48 kHz sampling rates, ensuring compatibility with standard digital audio formats.

What stands out

• High-performance DSP engine for complex audio processing with minimal latency (2.5 ms analog-to-analog at 48 kHz).
• Extensive control connectivity: Ethernet (RJ-45), RS-232C, and 8 GPI inputs/outputs for integration with third-party systems.
• Expandable via two MY-card slots, supporting optional analog, digital, or networked I/O cards.
• Selectable +48V phantom power per input, ideal for condenser microphones in conferencing applications.
• Rack-mountable 1U form factor with low 45 W power consumption.
