Question about Marantz DV8300 DVD Player

Distortion on left channel of analog output

When playing SACD's or normal CD's through the analog output I get very audible static/distortion on the left channel at certain frequencies. The distortion typically occurrs with vocals, but there are some instrumental guitar discs I have that the problem is also apparent on. The digital audio out is perfect, but can't use that for SACD.

I have swapped speakers, cables, preamp, and amps and the problem always comes down to the left analog output of the Marantz. There are 2 analog audio outs on the back panel, but they both behave the same. Is this a DAC problem, or??? Please help...I miss listening to my SACDs!

P.S. I bought the player used and I believe it has been doing it since I got it, but it sat for a month after I received it before I discovered the problem.

    I see. Ok, thanks. This may be a stupid question, but is that at all a do-it-yourself operation? I am handy and have access to a grounded workstation and wriststrap, so ESD should not be a problem. But is it possible to order the part, and is it easily swappable on the PCB?



    Thanks again,

    Joe

Based upon your description, the most likely caue is the D-A converter chip inside the marantz. This is a relatively common failure. Replacing the IC should resolve the problem.

    The PC board should be available, but won't be cheap. The Ic is probably available as well, but is likely to be a surface mounted device. These take special equipment for replacement. Check with a local servicer for the IC replacement cost.

Sound distortion with NAD T 514...


You are probably clipping in that midrange. Since the DVD player is fine and CD player is distorting: they are line level outputs, If you are running those through an equalizer- the equalizer should allow you add in a 10db attenuation.

If you are running them straight to the amp, The CD line level output should be about 1.5 volt peak to peak, it may be the line level input of your amp is only 1 volt and the DVD player simply has that level of output so does not clip..

Simply adding into the cable a 0.1 microfarad polyester capacitor for each channel should be enough attenuation to avoid clipping. The midrange is where you hear the most content in large part because that is the range that the human ear is most sensitive to. Which is why that portion clips. The DVD audio is actually recorded to the same specs as CD audio. You can confirm this by playing your CD disk in your DVD player. .

The problem is more likely to be with the wireless headphone set rather than the TV. It makes no sense that the signal changes channels. The only difference betweent he fixed and variable output is whether or not the volume changes the output signal amplitude. The channel selection process is not handled there. The distortion is likely due to the input of the wireless being overdriven. If available, turn down the input gain on the wireless and try again. Please update this with the results.

CLIP: red, to the left of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.

During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.

•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

Your PS3 may actually be playing the SACD layer but if you're listering through optical you're not going to get any better sound quality than CD.

For stereo SACD quality you can use the analog outputs; for multichannel SACD quality you'll need to use HDMI.

See the PS3 SACD FAQ.

I have distortion coming out of my front right channel of my AVR


Yes, sounds like your DSP chip has an issue. Not an inexpensive repair if that's the culpret. Around 400-500 to replace the chip. It's an awesome receiver and worth 300-400 in repair, however, a 3800 or 1800 can be had for 600-800 depending where you look. If you need more help, post a comment and I can help you some more.
