Product Overview

The KM 184 mt Octo Set represents the pinnacle of the "Series 180" lineup. Designed for high-end recording facilities and broadcast houses, this set ensures total acoustic consistency across eight individual microphones. The cardioid pickup pattern is frequency-independent, meaning sound rejection from the rear is excellent even at low frequencies, allowing for pinpoint-accurate imaging in multi-microphone arrays. Each microphone in this set is finished in a durable, scratch-resistant matte black that eliminates light reflections—perfect for on-camera use.

Product Description

The Standard for Multi-Microphone Setups:

The primary advantage of the Octo Set is consistency. When recording a full orchestra or a large choir, having eight factory-consistent KM 184s ensures a unified tonal balance across the entire soundstage. Whether used for a Decca Tree, immersive surround-sound arrays, or as spot microphones for an entire string section, the KM 184 mt Octo Set delivers a coherent and phase-stable audio image.

Sonic Clarity and "Freshness":

The KM 184 is world-renowned for its transparent and uncolored sound. It features a very smooth, linear frequency response with a deliberate, gentle treble lift around 9 kHz. This adds a touch of brilliance and air to recordings, making instruments like acoustic guitars, pianos, and woodwinds sound "fresh" and detailed without the need for post-production EQ.

Elite Engineering and Performance:

Each microphone in this set utilizes transformerless circuitry, which contributes to a massive dynamic range of 125 dB and an ultra-low self-noise floor of only 13 dB-A. This high-gain, low-noise design allows the KM 184 to capture the most delicate pianissimo passages of a solo flute while comfortably handling extreme sound pressure levels up to 138 dB (ideal for close-miking drum kits or brass).

Reliability on Stage and Screen:

The "mt" (Matte Black) finish is more than just an aesthetic choice; it is a technical necessity for modern television and film sets. The non-reflective surface ensures that the microphones do not create visual distractions under intense studio lighting. Additionally, the low-impedance output stage allows for cable runs up to 300 meters without signal loss, making it reliable for even the largest concert halls.
