  1. FS: My BNIB JBL MS-8

    Car Audio Classifieds
    Product Brand & Model: Hey guys, I'm am selling my never before used JBL MS-8. For those that don't know, this is an 8 channel amplified OEM integration processor with preouts, an advanced auto-tuning feature, as well as stereo up-mixing to Logic 7 multi-channel mode (with center channel...
  2. Can I run an Amp with unbalanced inputs...?

    General Car Audio Discussion
    Balanced transmission is not exclusive to XLR type connectors. They can come in all types of terminations, from TRS phono plugs to normal wired plugs. https://www.rane.com/note110.html
  3. Headphone jack

    Baggers And Motorcycles
    It's typically ~1vrms on quality phones. You mention not wanting to buy a "BT amp". Assuming you didn't accidentally mean a BT receiver to plug into your amp then I'd spring a few bucks and get one of these and make your life a lot easier. MBT-RX - Marine Audio - Amplifiers & Electronics -...
  4. Best sound system on the planet times two!

    General Car Audio Discussion
    So straight 2 channel stereo out the media player into a basic 2-way high/low active crossover and passive crossovers on the speakers tuned to a basic F/R type setup. Sounds like a high end home audio guy designed it with very limited and outdated knowledge of modern gear. "Best" is...
  5. JBL's MS-8 processor!

    It does, but mines has a white glue instead of clear.
  6. Audio Frog GB25 question

    System Design: Help Me Choose Equipment For My Car
    A quick comparison between the two. The GB25 has a smaller radiating surface area but is just as sensitive. The GB25 has a 25% larger voice coil (among other design aspects) which will make it handle more power (ie comes across as sounding cleaner). The GB25 has a much higher Fs than the...

    I never did.
  8. Optical disaster, Nx807 to Helix DSP

    General Car Audio Discussion
    It sounds like it could be "zipper noise". It's a digital artifact noise/pop/click that digital audio processors (and headunits as well) make when there is a digital process start/stop. That has to do with the audio chain, such as volume or track change request. But with modern DSPs it could...
  9. DSP,,, Back to Analog?

    System Design: Help Me Choose Equipment For My Car
    Yup, tone adjustments. That's all you should really need if everything is dialed in. Mostly to take care of differences in recording types.
  10. Alpine Europe 8 channel dsp with 100 watts per channel built in amp

    Car Audio Truth, Myths & Industry Dogma
    "Pure Class-D technology The Alpine DSP amp uses Class-D amplification technology: this means once an analogue input signal is converted to digital, it remains fully digital throughout the entire processing and amplification stage. With Class-D technology, an amplifier can reach much higher...

  13. JL VXi amps

    General Car Audio Discussion
    Do you mean the "Full Scale output (0 db) vs attenuated output (-12 db)" setting instead of the "Loudness" switch. Because that would be the one that you'd want to switch to "0dB" in order to get more output. The "Loudness" switch just boost the low end as you lower the volume on the head...
  14. JL VXi amps

    General Car Audio Discussion
    Input clipping is when you send too high a voltage for the input stage components (ie internal preamp) to handle and it overloads them (for a given input sensitivity setting). Clipping the signal to be sent to the DSP and/or be amplified. Output clipping is when you use too much of the input...

  16. Replacing sophisticated stock battery terminals

    Technical & Advanced Car Audio Discussion
    I would not replace it. I'd add an inline fuse further up the cable, away from the battery area so it is less likely to corrode over time. Then simply bolt the lug onto the large bolt that holds the OE fuse assembly to the OE terminal. But definitely not onto the terminal bolt like in the...
  17. New Alpine X series

    General Car Audio Discussion
    Maybe not, they seem to have chosen to go with a well dampened cone and the lowpass effect off axis mounting has over a more complex and expensive passive for the woofer. "SIMPLIFIED INLINE CROSSOVER With the introduction of the nanofiber cone, the X-Series’ midrange is capable of reproducing...
  18. JL VXi amps

    General Car Audio Discussion
    Not to speak for Manville but the only way that a source volume adjustment would not affect a tune further down the signal chain is if there is no volume dependent manipulation of the signal. You'll typically only a "loudness" feature that boost the treble and bass as you lower the volume...
  19. JL VXi amps

    General Car Audio Discussion
    I would investigate further. Some OE head units allow you to reprogram them so that they output only a base two channel low level signal. This is something your stereo shop might not be aware of, or something that a JL rep would not get into recommending due to complexity and/or car warranty...
  20. New Sony RSX-GS9

    General Car Audio Discussion
    Curious about this. Are you talking about decoding (ie playing back) both files over each other, on inverted, on a sound editor like Audacity? And having them cancel out to a very low level noise (-96dB at least)? Or some other way?
