NTI NTI 40DB Adapter For MR-PRO & MR2 600 000 312 40DB-ADAPTER £75.43
The 40db adapter may be used 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!!!
Technical Specifi cations: Attenuation: 40 dB +/- 0.3dB Output impedance: Balanced: 200 Ohm Unbalanced: 100 Ohm Balance mismatch: < 1%.
