Large Diaphragm Condenser Microphone Set Omnitronic CM-78MK2 with AS-04 Table Microphone Absorber System

The Omnitronic CM-78MK2 is a large-diaphragm condenser microphone set designed to capture clear vocals and instruments with natural detail. The package combines the CM-78MK2 condenser microphone with the AS-04 table microphone absorber system to reduce desk-borne noise and unwanted reflections when recording on work surfaces. This combination delivers a reliable, studio-style capture suitable for home and project studios, podcasting setups, streaming stations and broadcast applications.

Advantages

The CM-78MK2 provides high sensitivity and a large diaphragm for accurate transient response and rich midrange presence, which helps render voices and acoustic instruments faithfully. Paired with the AS-04 absorber system, the set reduces mechanical vibration and surface reflections from desks or tables, improving isolation and lowering background disturbances. The included absorber system is compact and easy to position, enabling a stable microphone placement and consistent sound quality across sessions.

Suitable for

• Vocal recording in home and project studios
• Podcasting and voice-over work
• Streaming and live commentary
• Recording acoustic instruments and ensembles
• Broadcast and voice content production

Key specifications

• Transducer type: large-diaphragm condenser
• Polar pattern: cardioid (primarily focused on source rejection from rear)
• Frequency response: designed for vocal and instrument clarity across low, mid and high ranges
• Sensitivity: optimized for clear capture of low-level and dynamic sources
• Required powering: standard phantom power (48 V) compatible
• Included isolation: AS-04 table microphone absorber system for desk noise reduction
• Mounting: table-mounted configuration with absorber system for stable placement

How to use

Mount the CM-78MK2 microphone into the AS-04 table absorber system according to the included mounting instructions so the microphone is securely held above the work surface. Connect the microphone to a mixer or audio interface that provides 48 V phantom power and set input gain so that normal peaks stay below clipping while preserving low-level detail. Position the microphone at an appropriate distance from the sound source — typically 10–30 cm for vocals depending on loudness and the desired proximity effect — and angle it toward the mouth or instrument for direct capture. Use the absorber to minimize contact with the desk and reduce reflected sounds; adjust room and microphone placement as needed to achieve the desired tone.

Usage recommendations

For best results, combine the CM-78MK2 with a pop filter for vocal work and place the AS-04 absorber on a stable surface away from heavy vibration sources. Monitor levels with headphones and perform a short test recording to fine-tune distance and gain. In noisy environments, consider adding additional acoustic treatment or relocating the setup to further reduce background noise.
