 +====== Sony MDS-JA30ES ======
  
 +{{page>equipment:infobox_deck}}
 +
 +Features: ATRAC 4.5 (IC: CXD2537R). Very similar to Sony MDS-JA50ES (below), with these differences: 1) 20 bit delta-sigma A/D (vs. 24 bit in JA50ES), 2) includes newly developed S-TACT IC pulse generation section [for DAC], reducing digital and analog noise, 3) has only one R-core transformer (vs. 2 in the JA50ES). Remote: RM-D14M

 +User comments: In comparison to the JA50ES, the '50 seems to have far better construction and power supply. As a result, it has slightly better numbers in dynamic range (105dB vs 104dB) and S/N ratio (108dB vs 107dB). These numbers are for playing back, so the difference in A/D converters has no effect. Notice that JA50ES is really heavy (14.3kg vs 9.3kg for the '30). If you look and touch these units, you can feel the difference of materials.
 +
 +Specs: Dynamic range: 104dB. S/N (manual: >104dB, brochure: >107dB, German Stereo magazine: >112dB). Freq. resp: 5-20kHz +/-0.3dB. THD: brochure: <.002%, German Stereo magazine: <.0012/.0013 (L/R). Line in: 47 kOhm, 500mV rms (min: 125mV rms). Coax in: .5Vp-p +/-20%, 75 Ohms. Optical in: 660nm. Line out: 2Vrms@50 KOhms, impedence: 10 KOhms. Digital out: -18dBm, 660nm. Phones: 28mW, 32 Ohms. GaAlAs laser output: 780nm @ <44.6 micro watts (measured at 200mm for the object lens surface of the optical pick-up block with 7mm aperture).
