Everyday Nti Audio Minirator -40db Adapter Attenuator Collection [f9Wnv8sG]

NTI Minirator -40dB Adapter

This attenuator can be utilized to generate high quality microphone level signals. It increases the signal-noise ratio for low level Minirator signals by -40dB.

You may use the adapter in conjunction with the Minirator MR2 or MR-PRO. The impedances of the adapter are matched for this use only! For safety reasons the adapter includes a pin 1 - fuse.

Application Example:

A low noise signal leveled at -40dBu is required substituting the mic signal. The THD+N of the generated Miniratorsignal without adapter is e.g. 54dB @ -40dBu.

For an improved signal-noise-ratio you may plug the - 40dB Adapter into the Minirator output and adjust the displayed level to 0dBu. The resulting level at the adapter output is -40dBu with an improved signal-noise-ratio, which is below the residual noise of high-end audio analyzers!!!
