Studio microphone AUDAC CMX230

The Studio microphone AUDAC CMX230 is a compact professional shotgun microphone designed for clear and focused audio capture. Built around a back-electret condenser capsule mounted on a flexible gooseneck with an XLR base, the CMX230 offers high directivity and pointability in a slender 19 x 280 mm enclosure. With a sensitivity of 42 dB, a frequency response of 50–18,000 Hz, low noise characteristics and wired mini XLR (3-pin) connectivity, it is suited to applications where intelligibility and precise pickup are required. The microphone operates from 52 V and weighs approximately 93 g. Its black finish is unobtrusive in conference, public address and announcement settings.

Advantages

The AUDAC CMX230 provides a highly directional pickup pattern that reduces ambient noise and focuses on the desired sound source. Its back-electret condenser capsule delivers a wide, flat frequency response and low self-noise for transparent reproduction of speech and close-range sources. The flexible gooseneck and mini XLR (3-pin) wired connection ensure reliable placement and secure signal transfer. Compact dimensions and light weight make it easy to position and integrate into lecterns, conference rooms or PA systems.

Suitable for

• Conference rooms and meeting spaces
• Public address and announcements
• Broadcast speech and voice recording
• Lecterns, podiums and fixed-installation setups
• Any application requiring directional vocal pickup with low ambient noise

How to use

Mount the AUDAC CMX230 on the intended lectern, stand or XLR-compatible base and route the mini XLR (3-pin) connection to the receiving audio device. Ensure the connected mixer or preamplifier supplies 52 V phantom power as required by the back-electret condenser capsule. Position the gooseneck so the microphone capsule points toward the intended sound source at an appropriate distance to achieve clear speech intelligibility. Adjust gain and equalization on the mixer or recorder to obtain a clean, undistorted signal while minimizing room noise.

Usage recommendations

For optimal results in conference and PA environments, align the microphone directly toward the speaker’s mouth and avoid aiming at reflective surfaces. Use a windscreen or foam pop shield if performers speak closely to the capsule to reduce plosives. When integrating with mixing consoles, apply only moderate high-pass filtering and minimal proximity boost to preserve natural voice timbre while controlling low-frequency rumble.
