3D measurement microphone

The Trinnov 3D Microphone is the measurement microphone for loudspeaker and room calibration with the Trinnov Optimizer. Besides measuring the frequency response, it also locates every loudspeaker in the room. Version V9 uses a mini-XLR5 connector and a built-in 9 V battery.

• Four capsules in a tetrahedral layout for three-dimensional loudspeaker localisation
• Captures frequency response, phase, group delay, impulse response, distance, azimuth, elevation and absolute level of every loudspeaker and subwoofer
• Frequency response 20 Hz to 24 kHz (±0.1 dB)
• Localisation precision ±2° horizontally and vertically, distance measurement accurate to ±1 cm
• Individually measured at the factory; the compensation file is supplied on a USB stick and is loaded into the processor before calibration
• Powered by the built-in 9 V battery; the microphone is switched on and off manually for measurements
• Detachable cable with mini-XLR5 plug at the microphone; on the processor side, depending on the cable, one XLR5 plug (Altitude 16, Altitude 32) or four XLR3 plugs (Amethyst, Altitude 32)
• For all Trinnov processors released before 2023 – not for NOVA and Altitude CI (these use the Ethercon 3D Microphone)
• Same measurement accuracy as the Ethercon version, but the two versions are not interchangeable
• Metal body with thread for standard microphone stands
• Included according to Trinnov: protective case, microphone, 10 m microphone cable with cable reel, suspension mount, thread adapter, USB stick with compensation file
