DANVILLE SIGNAL DSPNEXUS Audio Processor DSP

Danville Signal dspNexus: Extensive connectivity

The dspNexus offers several inputs to suit a variety of audio sources. These include coaxial (SPDIF), USB-B and a balanced stereo XLR input. This input connectivity is complemented by Bluetooth wireless connectivity supporting the high-resolution aptX HD codec.

The Danville Signal dspNexus automatically converts digital sources to 192kHz or 384kHz sampling frequencies, attenuating jitter and storing volume settings for each source independently.

Danville Signal dspNexus: State-of-the-art DSP processing

At the heart of the dspNexus is a SHARC DSP processor from Analog Devices, renowned for its performance in audio processing. This DSP enables :

• Managing active crossovers
• Sample rate conversion and jitter attenuation
• Room acoustic correction and bass management
• IIR and FIR filtering
• Time alignment in increments of 5 microseconds
• Digital RIAA reproduction for vinyl records

Danville Signal dspNexus: Even more features

The Danville Signal dspNexus integrates many useful additional features:

• Headphone amplifier: The dspNexus features a dedicated amplifier with independent settings for optimal headphone listening.
• Microphone input with 48V phantom power: Facilitates precise acoustic measurements thanks to a built-in measurement ADC, allowing calculation of time delays for each loudspeaker.
• External amplifier control: External amplifiers can be muted or put on standby when the system is not in use.

Danville Signal dspNexus: A scalable system

The ADC, DAC and DSP modules of the dspNexus are replaceable, offering the possibility of future upgrades without replacing the whole unit. DSP and display software updates can be performed without opening the chassis.

Danville Signal dspNexus: Model dspNexus 2/8

This specific model, the dspNexus 2/8, offers one stereo input and eight outputs, and is ideal for creating a fully active DSP crossover. This means you're designing a loudspeaker that won't use passive crossovers, relying instead on a bank of power amplifiers driving each of your loudspeakers individually.

This model is particularly suited to loudspeaker manufacturers wishing to integrate custom solutions, DIY audio enthusiasts, or audiophiles wishing to optimize their system with active crossovers.

The dspNexus 2/8 is supplied with a licensed version of Audio Weaver from DSP Concepts. This is a graphical design tool that allows you to create quality crossovers, tailored to the specific requirements of your loudspeaker system. A guide to using the tool effectively is also included, or in some cases Danville Signal can put you in touch with a crossover specialist for assistance.
