Sony MZ-RH1 MIC Input

RightMark Audio Analyzer test

by John Beale  Dec. 27 2006

Testing chain: Echo Audio Mia signal at +0.86 dBu -> 65.7 dB atten = 
-64.8 dBu dBu into RH1 MIC IN 
REC gain maximum: Mic Sens.  High, +30 Rec Gain
Sampling mode: 16-bit, 44 kHz (PCM Uncompressed)

Recorded file: 0 dBfs = -64.3 dBu 
RH1 noise floor is -58.5 dBA or -122.8 dBu (A-weighted)

note: attenuator output impedance = 1 kohm, thermal noise = -127 dBu
