NTI delivers portable audio test tools

Schaan, Liechtenstein — NTI has increased volume production for its flagship Minirator MR-PRO and latest version MR2 portable signal generators. The battery operated MR-PRO and MR2 handheld audio test tools are optimized for systems verification and fault-finding tasks.

The MR-PRO delivers minimal residual distortion of <-96 dB, a maximum output level of +18 dBu, together with unique functions for continuous monitoring of the impedance, signal balance and phantom power. In addition, an integrated cable testing function promotes the MR-PRO to the level of a cable analyzer, simplifying troubleshooting tasks.

The portable signal generators also feature a multi-function rotary wheel and efficient function keys to ensure fast access to all the signal functions and parameters with one hand including sine, pink and white noise, logarithmic stepped sweeps, gliding chirp signals, polarity test signal (as in MR1), and delay test signal for use in conjunction with the AL1 real-time acoustical analyzer. Both units feature ergonomic housings and a scratch resistant display that are designed for field use and heavy duty applications.

In addition to the classic test signals provided by both units, the MR-PRO also offers playback of WAV-based test signals. Data exchange is simplified via the USB port. This enables the MR-PRO to generate any complex test pattern such as the NTI STI-PA
signal, or simply act as line identifier in a broadcast chain.
