    Background Noise

    I bought my new HT components about 3 months ago (1095, 1066, B&W CM6, Pioneer CMX503, Pana RP62). Initially, I had a ground loop problem, but after I connected the MAGIC splitter to my cable, the hum went away. Lately, however, I have been noticing a very annoying background noise while watching DVD. In particular with certain movies (25th Hour, Boogie Nights, Good Girl), during silent, dialogue-only scenes, I can clearly hear pretty loud background noise. It's worse during some scenes than others. It gets better when switching Dynamic = Max and Cinema Eq = On. Also, the problem is less severe when watching cable than when watching DVD.

    I also have to turn up my pre-amp a lot (about 70) to get the right volume.

    I have no idea if this is a problem with my ROTEL amp or my DVD.
    Please help -- I don't know what else to try...

    How is your DVD's audio connected to your 1066? Is it toslink/digital coax or is it thru the analog L/R jacks?

    If its thru the analog jacks you are probably hearing crosstalk from another device that you have connected to the analog jacks too (i.e. cable box). Crosstalk in the analog environment is, unfortunately, normal in most audio equipment. It comes from all the analog inputs sharing a common ground. Switching to using a digital connection (toslink/coax) will clear it up.

        Thanks for your replies. My DVD is connected through a optical digital audio cable. So that should not be the prolem. I have another DVD player and will hook that up to see if it makes a difference.

        I also don't think I have the latest firmware. Maybe upgrading the firmware will help?

        Here is some detail on the Magic splitter

          Noise

          In the context of loudspeaker measurements made during the design process, noise refers to any unwanted electrical or acoustic signals that can interfere with the accuracy of the measurement. Noise can be introduced through various sources, and it can affect the reliability and precision of the measurements, making it essential to minimize its impact for accurate loudspeaker evaluation. Sources of noise include:
          • Background Acoustic Noise: During loudspeaker measurements, ambient

          Exploring Common DIY Terminology - Signal-to-Noise Ratio (SNR)
          by technodanvan
          Signal-to-Noise Ratio (SNR)

          The signal-to-noise ratio (SNR) is an important parameter that helps evaluate the performance and quality of the audio output. In the context of audio, SNR refers specifically to the ratio of the desired audio signal (the sound produced by the loudspeaker driver) to the background noise generated by the speaker itself or the overall system.

          The formula to calculate SNR in decibels is:

          SNR (dB) = 10⋅log⁡10(PowerSignal/PowerNoise)
