Nexo DTD-I-U is compatible with amplifiers from other manufacturers, the Nexo DTD Digital TD Controller for PS Series cabinets and LS Subs makes the world’s favourite compact, high-output system even more accessible.
The Nexo DTD delivers advanced speaker control processing taken from the NEXO NXAMP in a compact, rack-mounting device. Providing sophisticated control over crossover, EQ and time-alignment along with speaker protection, the DTD is very easy to use, with automatic amplifier sensing and simple Sub Gain, Main Gain and Crossover Mode control available directly from the front panel (DTD-T touring
The DTD combines efficient speaker processing with a flexible range of inputs including stereo balanced analog inputs, an AES input and a USB port enabling direct driverless audio playback from laptops, etc. An optional Dante input is also available.
Advanced signal processing
Nexo DTD uses state-of-the-art audio processing to deliver high precision EQ and Linear Acoustic Phase algorithms, phase compatible with all PS and LS cabinets, along with other speakers in the NEXO range. High-end AD and DA converters and 64-bit/96kHz processing ensure an analog in-to-analog-out dynamic range greater than 112dB, with distortion kept to under 0.001%.
Touring and Install versions
Both Touring (DTD-T) and Install (DTD-I) versions are housed in a rugged, low-depth rack-mounting case and feature a universal power supply. The touring version has analog input and output connectors (XLR and Speakons) on the front panel, removing the cost need for an additional patch panel. The front panel display shows the current PS/LS set up, and features controls for Sub/Main output gain and a switch to select Wideband, Crossover or User mode. Set up from a Mac/PC connected via USB, User Mode offers additional control over Speaker/Sub model selection, Crossover Frequency selection, Delay on Main and Sub outputs, Gain for each output, Input/Output Meters including protections, User EQ (2 x 8 bands parametric), Limiters and Settings Lock with Password.
The install version has all the connectors except mini-USB located on the back panel. There is no hardware control on the unit; all parameters are set in User Mode from a Mac/PC connected via USB, allowing settings to be locked to prevent accidental changes.
Easily accessible firmware updates
The USB port can also be used to update firmware, add new functions or download new NEXO speaker presets.
