1283.0. "Sony DT3 - High-pitched whine - OK?" by TELCOM::ROSENBERG (Dick Rosenberg VRO5-2/C7) Mon Jul 25 1988 07:47

    I recently bought a Sony DT3, which I like a lot. The only problem
    is I hear a high-pitched whining sound when I am sitting close to
    my stereo or when I am using it as a standalone portable. Is this
    normal for this unit?

    My DT-3 has no such glitch.  
    
    Maybe you ought to visit your seller and check another unit.  You
    may have a bad output filter.

1283.2SET QUESTION/MODE=RETRYTELCOM::ROSENBERGDick Rosenberg VRO5-2/C7Tue Jul 26 1988 08:109
    I misdescribed the noise. It is mechanical noise. You can hear either
    the motor as it spins the disc around, or the spinning mechanism.
    You can hear it until you get about 4-5 feet away when you are playing
    a disc softly. The music itself is perfect. The question remains;  Is
    this kind of noise normal on a DT-3?
    
    Thanks,

1283.3D15 does it too!USWRSL::GREENHAJOTue Jul 26 1988 10:135
    I can't speak for the DT-3, but I have the exact same noise with
    my D15.  I can't hear it with the headphones on, so I haven't bothered
    getting it checked.

1283.4Any Quiet Ones?TELCOM::ROSENBERGDick Rosenberg VRO5-2/C7Wed Jul 27 1988 08:0610
    Ok, now let's try the question the other way (so I know whether
    to return the thing or get a different one from Lechmere's before
    my 30 days is up).
    
    Does anybody have a Sony portable in the D3, DT-3, D4, D?, range
    where you can't hear the mechanical noise of the disc spinner?
    
    Thanks Again,

    My D-7 is as quiet as a church.  The only thing you hear is the
    laser head moving during reset or shuffle.  The spinner is only
    audible when it's first spinning up, and then very little.

    	I have to get to within a foot or so before I can hear
    my D3 in normal surroundings.
1283.7Problems with a D10/D100YUPPY::OHAGANThu Jul 28 1988 06:5111
    I have had a D100 (D10 in USA) for 2 months and I get a similar
    kind of mechanical noise from the player when it is running to the
    problem described originally in this note. Also when I put the case on
    and carry it around as described in the manual, I get a knocking noise
    coming from the player. However if I turn it 90 degrees either way, it
    disappears. I don't think this should happen with it and I'm thinking
    of taking it back to the shop.                              
    
    Anyone come across my problem with a Sony portable?

1283.8DT3 is quiet enough for me (& cheap, too)VEEJAY::ECTORStax of Wax, Lbs. of plattersThu Jul 28 1988 12:2926
    
    
    The noise described is exactly what I hear when I get close to my
    DT-3. It does seem mechanical related, and is inaudible from 2-3
    feet in a quiet room and not a problem at all with the headphones
    on. 
    
    I'm quite pleased, since I went to "Circuit City" (a fairly new
    - at least to California - electronics/appliance department store)
    to purchase the Crown D-110 for $98.00. I walked in as they were
    marking down discontinued/floor sample stuff. They had 2 DT3's,
    so, I walked out with a unit, an A/C adaptor & shoulder strap
    along with a 24 month full parts/labor warantee for $117.00. I didn't
    get the rechargable battery pack, but for the price I can't complain.
    
    Did I get a good deal ??  The guy told me that if it became
    uprepairable during the 24 months, they'd probably upgrade, rather
    than work on it - oh by the way, they have their own service center
    at each store.
    
    Except for TV's, I usually shy away from SONY, but I'm really pleased
    with the unit (I'm listening now.....great stuff).

    re. .0
    
    I think your question may have a better go-at-it in the AUDIO
    notesfile.   Give them a shot if you haven't already.
