Frequently Asked Questions - M45 Shortgun Audix

How do I install the M45 microphone in a ceiling tile?

Drill a 1.5-inch (38 mm) hole in the ceiling tile. Remove the knurled ring, insert the module through the hole, and reattach the knurled ring from below. Connect the RJ45 cable to the M45 module.

What type of cable is required for the M45?

Use a shielded Cat5e, Cat6, or Cat7 cable with RJ45 connectors. The cable carries audio, power (PoE), LED control, and logic signals.

How many M45 microphones can I connect to one DN4 interface?

The Audix DN4 interface supports up to 4 microphones. Connect them directly to the DN4 via RJ45 cables.

Do I need special software to use the M45?

Yes, you need Dante Controller for audio routing. For full control (gain, filters, LED), install the Audix DSP Plugin (available for Q-SYS or other DSPs).

How is the M45 powered?

The M45 is powered via Power over Ethernet (PoE). Connect it to a PoE-enabled network switch or a PoE injector.

Can I use the M45 with a third-party DSP?

Yes, audio channels can be routed via Dante to any Dante-compatible DSP. For control functions, check the Audix API or plugin availability for your DSP.

How do I adjust the LED color on the microphone?

Use the Audix DSP Plugin (e.g., in Q-SYS Designer). The plugin allows you to select the starting LED state and color per microphone channel.

What is the purpose of the seismic cable?

The seismic cable provides a safety restraint. Wrap the cable through a beam, eyebolt, or hanger and secure it with the cable stay barrel to prevent the microphone from falling.

How do I confirm the microphone is discovered on the network?

Open Dante Controller on your computer. The M45 should appear as an audio device. In the Audix plugin, it will be automatically recognized and populated by model number.

What is the coverage area of the M45 microphone?

The M45 has a directional pickup pattern. You can adjust its orientation (see Figure 7) to point toward the desired area. The exact coverage depends on the mounting height and environment.

USER MANUAL M45 Shortgun Audix

THE AUDIX INTEGRATED MICROPHONE SYSTEM | DANTE-AES67

The Audix Dante-AES67 microphone systems are the industry's first integrated solution to eliminate multiple connectors by providing audio, LED status and logic functionality with a single RJ45 cable connection. This design reduces conventional wiring and installation time by 90% and eliminates wiring errors. Once the connection is made to the network via the Audix DN4 interface, the Audix microphone(s) will be automatically recognized and populated by model number in the Audix DSP plugin.
