The NEXO DTDIU is a dedicated digital speaker controller in the install-optimised DTD-I form factor, delivering advanced crossover, EQ, time-alignment, and speaker protection processing derived from NEXO’s NXAMP technology. Purpose-built for permanent installations, all connectors (except the mini-USB configuration port) sit on a rear barrier strip, and settings can be locked to prevent accidental changes — making it well suited to venues, houses of worship, and corporate AV environments where the system should stay exactly as the integrator configured it.

Note
This is a speaker processor, not an amplifier — it requires external amplification to drive NEXO cabinets. The DTD-I has no front-panel controls; all configuration is performed via the mini-USB port using PC/Mac software. For the Dante-enabled install variant, see the DTDIN.
