Frequently Asked Questions - DN4 Audix

How many microphones can I connect to the DN4?

The DN4 has four RJ45 ports for Audix single-element microphones.

Does the DN4 require a separate power supply?

It can be powered via PoE (Power over Ethernet) or an optional external 48V DC supply (PSDN4C) if PoE is not available.

What type of cable is recommended for microphone connections?

Use CAT5, CAT6, or CAT7 cable. In high RF interference environments, CAT7 shielded cable is recommended.

How do I reset the DN4 to factory defaults?

Press and hold the RESET button for more than 3 seconds until the STAT LED changes from green to red.

Can I control LEDs on connected microphones?

Yes, the DN4 provides two logic outputs per port (5V, up to 10 mA) that can drive LEDs, controlled via the 3rd party API (NDC).

What is the maximum cable length between microphone and DN4?

Up to 300 feet (91 meters) with CAT7 shielded cable.

How do I configure AES67 instead of Dante?

Follow Audinate's AES67 configuration guide available at the link in the manual. The device supports both Dante and AES67.

What do the LED indicators mean?

SYS, ERR, SYNC indicate Dante chipset status. STAT shows hardware/software state. The Ethernet port has green (link) and amber (activity) LEDs.

How do I update the Dante firmware?

Use Audinate's Dante Firmware Update Manager over the network. Refer to the user guide for failsafe recovery.

Can I use the DN4 with non-Audix microphones?

No, the DN4 is designed exclusively for Audix RJ45-equipped single-element microphones.

OVERVIEW

The Audix DN4 Dante-AES67 microphone interface is at the heart of an integrated microphone system that is the fast, trouble-free way to stream Audix audio performance through Ethernet networks. High-quality audio and all microphone functions — including on-off contact closure and LED status indicators — are available through a single CAT5 - CAT7 cable with RJ45 connections. This simple configuration eliminates wiring errors, accelerates installation, and reduces cost. The result is true plug-and-play installation.

The DN4 features four inputs for Audix RJ45-equipped, single-element microphones and has two 5V logic outputs per port, with source/sink capability for LEDs that are controlled by network-connected DSPs and one logic input per single-element microphone port for external contact closure. Low-pass and high-pass filter settings are available on each audio channel, as are eight selectable gain levels, with all settings confi gurable via software.

HARDWARE FEATURES

1. Ports for Audix RJ45-equipped, single-element microphones
2. Status LED indicators
3. Ethernet and PoE RJ45 jack

4. Reset button

5. Optional external DC power supply input jack (PSDN4C) (when PoE is not available)

INSTALLATION

The DN4 is designed to be mounted to a flat wood or metal surface on top or under a table or in the ceiling using the supplied mounting brackets. Install the mounting brackets by aligning the off set holes in the bracket with the threaded holes on the sides of the interface and attach using the supplied screws. Position the interface on the mounting surface and mark the mounting holes. Drill holes in the mounting surface and attach the unit using screws appropriate to the material. Secure seismic cable under any screw.

CONNECTIONS

The DN4 has four RJ45 ports for connecting any Audix RJ45-equipped, single-element microphone, including those with integrated support for LED indicators and contact closures. All ports provide 48V phantom power.

Attach Audix RJ45-equipped microphones to the microphone ports with CAT5, CAT6, or CAT7 cable*. In high RF interference environments, Audix CAT7 shielded cable is recommended. All models of Audix RJ45-equipped microphones have been tested to function with CAT7 cable lengths up to 300 feet between microphone and DN4 interface, allowing for more flexible installation and longer cable runs than other Dante interfaces on the market.

Connect the Ethernet cable to the PoE port of the DN4 and the opposite end to a PoE-enabled port on an appropriate switch, using CAT5, CAT6, or CAT7 cable.

If PoE is not available, a PoE injector may be used or connect the optional 48V external power source (PSDN4C) to the auxiliary power jack on the front of the unit.

LED DESCRIPTIONS

There are four LED indicators on the front of the unit, as shown below.

The SYS, ERR, and SYNC LEDs show the status of the Dante chipset. The STAT LED indicates the state of the hardware and 3rd party control software.

There are two LEDs on the Ethernet / PoE RJ45 port. The left LED is green and will be on when a 100 Mbps Ethernet link is working. The right LED is amber/orange and will flash to indicate data activity.

The reset button performs two different operations. To select one of these operations, use the end of a small paperclip or similar pointed item to hold down the reset button for the number of seconds indicated below, then release.

The Dante chipset can be restarted by quickly pressing and releasing the RESET button. The STAT LED will not change while the RESET button is being pressed. No user settings are cleared during this operation. Note that audio streaming will stop, the device will disappear from the network and reappear a few seconds later.

To reset the device to factory default settings, press and hold the RESET button for longer than 3 seconds. The device settings will be erased and the Dante chipset will enter factory mode (SYS, ERR, and SYNC LEDs are amber). The device may be updated with Audinate's Firmware Update Manager in this mode. To resume normal run mode, reboot the Dante device by quickly pressing and releasing the RESET button, as described before.

Operation STAT LED State

Reboot Dante into runtime mode	Press and release the reset button quickly, while STAT LED is green.

Clear device configuration Hold the reset button for longer than 3 seconds. Release when STAT LED changes from green to red.

The settings cleared to default values include, but are not limited to, the following:

• Dante device name
• IP address (dynamic)
• Audio routes
  • Pre-amp gains (0 dB)
  • High-pass filters (15 Hz)
• Low-pass filters (off/bypassed)
• LED outputs (off)

THIRD-PARTY API: NETWORK DEVICE CONTROL

In addition to Dante audio streams, the DN4 microphone interface provides logic and audio controls using the 3rd party API: Network Device Control (NDC). The NDC API provides the following functions:

• Control up to two (2) LEDs or Logic Outputs on each mic port
• Read one (1) Button or Logic Input on each mic port
• Read microphone ID value

Complete API documentation is available in document NDC Protocol & API v1.0.1, available at audixusa/API

SETTING UP AES67 STREAMS

To configure the device to support AES67 streams instead of the Audinate Dante flows, follow Audinate's AES67 configuration guide, available here:

- https://dev.audinate.com/GA/dante-controller/userguide/webhelp/content/aes67_config.htm

Note that other manufacturers supporting AES67 may also provide their own instructions for setting up and using AES67 streams from a compatible Dante device.

UPDATING DANTE FIRMWARE

Audinate periodically updates the firmware for Dante devices and offers a utility for updating devices over the network. Refer to the Dante Firmware Update Manager User Guide for instructions on how to use the Audinate update utility, including how to recover from failsafe mode.

APPENDIX A: ADVANCED CONNECTIVITY GUIDE

The Audix Dante | AES67 Integrated Microphone System is designed to eliminate the need to fabricate RJ45 microphone connections. If custom connections are desired, use the diagrams below.

The LED (Logic Out) output lines provide 5V outputs and can drive up to 10 mA of current, enough to power LEDs directly without additional circuitry. The LED signal is controllable with the 3rd party API (see previous page).

The Button (Logic In) input line operates on 3.3V and provides an internal pull-up. This means a contact closure should be connected across the BUTTON and DGND pins without any additional circuitry. Do not attempt to drive voltage into the BUTTON pin. Only use open-drain drive circuitry. The logic input signals from all microphone ports are read with the 3rd party API (see Section 6).

The audio input lines are balanced, differential inputs. Industry-standard 48V phantom power is always available on these lines.
