Performance Enhancements Available :


The PMD 620MKII Basic rebuilds the PMD 620MKII mic preamp with a very low noise, high slew rate op amp that dramatically enhances detail and clarity while lowering noise and audible distortions. This upgrade also increases the mic input gain by 6dB in order to record lower signal levels without using the ALC circuit. All features remain intact.

The PMD 620MKII Concert rebuilds the PMD 620MKII mic preamp with a low noise, very low distortion and high slew rate op amp that dramatically enhances detail and clarity while lowering noise and audible distortions. This upgrade also improves the line input circuit. The built in mics are removed to maximize microphone input quality, all other features remain intact. Concert MOD parts are selected by ear to optimize the PMD 620MKII for recording music.

    Marantz PMD620MKII Sample Files in the WAV format

    Marantz PMD 620MKII Super MOD Samples
    These samples are recorded with the DPA 4060's on a dummy head and the MPS6030 Power Supply.
    The traffic sounds are from a road a bit over 1 mile away.
    The mics for the ambient sounds are placed on my rear deck, about 150 feet from the woods.
    The wind chimes/drum sample was made indoors with the same mics from a 6 foot distance.

    PMD 620MKII SAV files from a RightMark 6.1.2 Audio Test
    I will post updated data on the Super MOD 620MKII as time permits. Hiss has been audibly reduced, now even better for binaural nature sounds !
    These measurements use small signal levels that represent realistic mic output signal levels. Measurements at higher signal levels or worse, without the signal level specified may not accurately reflect real world conditions or results. When listening to the sample files above, the ear will detect a very open, detailed and natural sounding 3D soundfield !

    PMD 620MKII SMOD @ -30dB
    THD 0.0060 Noise -86.7 dbA Dynamic Range 86.8 dbA, measured at the line out jack.
    PMD620MKII SMOD @ -50dB
    THD 0.0082 Noise -82.5 dbA Dynamic Range 82.5 dbA, measured at the line out jack.

    Marantz PMD 620MKII Basic MOD Samples
    The sample files below were recorded with no mic at 40dB of gain.
    This demonstrates the improved noise floor of the Basic Upgrade.
