Sony MZ-R30

Components: Optical Pickup: KMS-250A/J2N, ATRAC IC: CXD-2652R, RF amp: CXA-2523R

Additions between MZ-R30 and MZ-R3: Sampling rate converter, track-search (can view other track titles with jog dial while a track is playing), digital synchro-start recording, digital mono recording uses (L+R)/2 (MZ-R3 is L-channel only).

Notes: The MZ-R30 has no FAST playback function, but the unit has a FAST indicator on the LCD (you can see it if you look at the LCD in oblique light) because it is the same LCD used in the MZ-B3 (dictation recorder), which has the FAST playback function.

Setting recording level: The values for each bar of the level meter of the MZ-R30 are (from bottom to top): 1 = -51dB, 2 = -40dB, 3 = -30dB, 4 = -20dB, 5 = -12dB, 6 = -6dB, 7 = -4dB, 8 = -2dB, 9 = 0dB (“OVER”), These values are the minimum values for which the bars light up. Each bar actually represents an interval. For example, bar 1 indicates a level of -51dB to -40dB, bar 5 indicates -12dB to -6dB and bar 8 indicates -2dB to 0dB. When manually setting the record level, this means you should adjust the level so that the 9th bar doesn't light up. (Or at least not very often.) Mathijs Vermeulen (
