NTI Audio MR Pro Minirator

Love it, Use it most days when working, useful for checking equipment.

80% of audio problems sourced in cables, this device will help you intensely and accurately to confirm the quality of your microphone/line and speaker cables for audio systems and loudspeaker. we use it more than 10 years and it saved a lot of time and gives highly accurate results while calibration result deviation since 10 years is negligible. this proofs that we have a high quality device in our hands and we are buying another one too without hesitation.

Must have, ther is no other tool like this one!
