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.

Features
All connectors on rear barrier strip, clean, tamper-resistant installation
Lockable settings prevent accidental changes after commissioning
Configuration via PC or Mac over USB, no front-panel controls to interfere with
Speaker processing algorithms derived from NEXO NXAMP technology
Crossover, EQ, time-alignment, and speaker protection in a single unit
Linear Acoustic Phase algorithms, phase-compatible with NEXO PS, LS, and other cabinets
Stereo balanced analogue inputs, AES input, and driverless USB audio playback
Automatic amplifier sensing for streamlined system setup
NoteThis 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.
