Audix DN4 - 4-Channel Dante/AES67 Audio Interface for Microphones RJ45
The Audix DN4 represents the core of a modern, streamlined professional audio ecosystem, designed specifically for system integrators and sound professionals seeking maximum efficiency without sacrificing quality. This Ethernet audio interface is the centerpiece of the Audix integrated microphone system, enabling seamless signal transmission over Dante and AES67 networks. Its architecture is designed to completely eliminate the complexities of traditional analog cabling, facilitating quick, reliable, and error-free installations in corporate, educational, and commercial environments.
Capable of managing up to four independent channels, the DN4 transforms technical complexity into a plug-and-play experience. Thanks to its connectivity via standard CAT5, CAT6, or CAT7 cables, this unit not only transmits high-fidelity audio but also manages advanced logic functions such as contact closure for power buttons and powering status LEDs on microphones. This means that a single network cable covers all communication and control needs, drastically reducing labor time and material costs on every project.
Studio Audio Quality Network
Sound excellence is an undisputed priority in Audix engineering. The DN4 processes audio with 24-bit resolution and a 48 kHz sampling rate , guaranteeing crystal-clear clarity and absolute fidelity to the voice. Each of its four input channels features high-end preamplification circuitry, offering eight software-selectable gain levels . This allows for precise adjustment of the input sensitivity for each connected microphone, ensuring an optimal signal level before it enters the digital network, eliminating background noise and unwanted distortion.
Total Control and DSP Processing
More than just a converter, the DN4 acts as an intelligent control center. Through its software interface, integrators can configure independent high-pass and low-pass filters for each channel, shaping the frequency response to suit the room acoustics or speaker characteristics. In addition, the unit includes dedicated I/O (Input/Output) logic ports for each microphone connection. These ports provide two 5V logic outputs capable of powering and controlling external LEDs (ideal for status light rings on conference tables) and a logic input for integrating mechanical or touch pushbuttons, allowing microphones to be muted or unmuted directly from the user's position.
Reliability and Robust Construction
Designed, assembled, and tested in the USA, the Audix DN4 is built for 24/7 operation in mission-critical facilities. Its rugged metal chassis protects internal components and provides effective shielding against electromagnetic interference (RFI), a crucial factor in modern buildings saturated with wireless signals. The unit features internal flash memory that stores all configurations, ensuring that in the event of a power outage, the system automatically recovers to the last saved settings without requiring technical intervention.
Key benefits for the integrator
-
Ultra-fast installation: The use of standard RJ45 connectors for microphones eliminates the need for field soldering and reduces connection errors.
-
Simplified remote management: Compatible with Dante Domain Manager (DDM), it allows user management, security, and routing across complex networks.
-
Power versatility: It operates via PoE (Power over Ethernet), eliminating the need for local power supplies and simplifying electrical wiring.
-
Mounting flexibility: Includes brackets for discreet installation under tables, on ceilings, or in equipment racks.
Ideal use cases
The versatility of the Audix DN4 interface makes it the perfect solution for a wide variety of environments where speech intelligibility and aesthetics are paramount:
-
Meeting and Conference Rooms: For connecting surface or ceiling microphones with visible LED status control.
-
Auditoriums and Convention Centers: Enables rapid deployment of multiple microphone points with existing structured cabling.
-
Educational Institutions: Ideal for hybrid classrooms and reading rooms where high-quality audio is required for transmission or recording.
-
Places of Worship: Facilitates the clean installation of microphones on lecterns and altars without visible or bulky cables.
-
Courts and Government: Ensures secure and clear recordings with encryption and management options through the Dante network.
Frequently Asked Questions
What type of microphones can I connect to the DN4?
The DN4 is specifically designed for Audix single-element analog microphones equipped with an RJ45 connector (such as the M55D, M70WD, or compatible adapters). It is not compatible with standard XLR microphones without an adapter or specific RJ45 wiring following Audix's wiring scheme.
Do I need an external power supply?
Not necessarily. The unit operates using PoE (Power over Ethernet) supplied by a compatible network switch. However, it also has an input for an external 48V power supply (not included) if the network does not support PoE.
Does the DN4 provide phantom power?
Yes, each of the four ports supplies 48V phantom power, which is required for compatible condenser microphones.
Is it compatible with AES67?
Yes, the Audix DN4 supports AES67 audio streams, allowing interoperability with other IP audio systems that do not exclusively use the Dante protocol.
Project description
A 4-channel network audio interface designed for integrating analog microphones into Dante and AES67 ecosystems. The unit features four balanced inputs with shielded RJ45 connectors, providing 24-bit/48kHz A/D conversion. It offers 48V phantom power, RFI filtering, and eight software-selectable preamp gain levels (0dB to +36dB), along with independently configurable high-pass and low-pass filters per channel. It includes logic control with two 5V outputs and one input per port for managing external LEDs and pushbuttons. Power is supplied via PoE (IEEE 802.3af) or an external 48VDC power supply. The metal chassis is Plenum-rated (UL2043) and suitable for ceiling or under-desk mounting.
