2v vs 5v preamp Only show this user from my experience of going from 2v-5v on the 5v it seemed like the loud function was on if it makes any sense at all. So there are my questions: 1. Could be an issue, could be unimportant. Nov 4, 2012 · 2. I think you'd be able to hear the difference between a $160 speaker and a $60 speaker even in a car, I don't think you'd hear the difference between a $160 speaker and a $500 speaker though, even between a $120 speaker and a $160 speaker there will be little difference, a $60 speaker will sound like a $60 speaker though. Nov 19, 2007 · 2V and 5V preamp output Jump to Latest 2. Even if the power amp loads down the preamp signal to half it's open circuit value (equal impedances, 1:1 ratio), there won't be any sonic effect. The goal is that if you pick up 200 mV of noise, if you have a 2V signal that's 10%, whereas if it's a 5V signal that's under 5%. Im looking at This Pioneer and noticed it has 2v pre-outs instead of 4v. Im currently running 4 amps, off the pre-outs, so how will that affect my sound? Also how will I have to adjust my gains to compensate for it? Or would it be better to look for a head unit with 4 v pre outs like This Alpine or one with 5v pre outs like this Kenwood? The Apr 12, 2011 · General Q & A - 2V vs 5V stereo amp output leads - What will be the difference between having 2V vs 4 or 5V amp output leads? Is it even noticeable? Jul 28, 2020 · I don't believe this AVR can put out 4V on the pre-amps. the only real du=ifference between the 2 is the 90 has 4v preouts while the 900 has 2v. Jul 24, 2013 · I am curently stuck between some from Kenwood (KDC-X397) and Pioneer (DEH-X7500S) because both have 4V preamp models, but for the same price, I can get Bluetooth with a 2. My processor only accepts up to 2. Those ratios never happen in practice. Mar 10, 2008 · 2V vs 5V pre-amp outs Jump to Latest 3. I had to run a crossover to 'normalize' the signal. I would just know it know how big of a diffrence there is between 2 and 4 volt as far as SQ with the speakers for the front and rear. Apr 8, 2009 · A higher signal voltage does alot for you. Nov 5, 2009 · Was really only looking for the 3 sets of preamp outputs, ipod hookup, and USB port. The Premier signal was CONSTANTLY causing my amp to clip. Eclipse and Panasonic rated theirs at nominal, and the Premier was Max. My impression is most amps would have higher Nov 29, 2007 · I am of the opinion that you can have "noisy" 4V pre-outs as easily as you can have "noisy" 2V pre-outs. 2V preouts will need to amplify the noise more than a 5V preout to get to the same listening level. First, it keeps the noise floor to a minimum. Thread starter Dtrom; Start date Sep 27, 2012; Live activity Nov 4, 2012 There are plenty of SQ installs with 2V preouts.

Cheap 4v vs expensive 2v, quality of the components actually producing that signal, DAC inside the headunit etc. Feb 25, 2020 · @amirm, I'd just like to know why a 2v output measurement can be more useful than a 1. It's feeding an Alpine PDX-5. Nov 8, 2006 · I would prefer a preout of 5v or even 8v over 2v because I have to turn the gain on my amp past 3/4 gain just to get it to sound good (at a 4 ohm load). It's as simple as this: 100w rms is 100w rms no matter what preamp voltage you have. Nov 1, 2021 · Currently running a pair of Stereo Integrity M3 Carbon's, a pair of Stereo Integrity M25's, a pair of Dayton Audio Epique E180HE-44's, and a pair of CSS Audio (Creative Sound Solutions) SDX12's with a pair of JL Audio XD 400/4's for the front stage and a pair of Wolfram Audio W3000. Wondering if it's worth passing on a head unit that has 2v, just because of that fact. IF you had a 2V pre-out, then upgraded to a 5V pre-out without adjusting your gains you would be trying to make your amplifier run up to 50V, which is MEGA clipping. All other things Sep 25, 2021 · Even the 2v output of my CD player is 13x higher. Physically speaking, it's the difference between the gain knob at 1/4 (for 5V) or 1/2 (for 2V). Quality of the signal is more important then its level. 5v one in unbalanced/RCA for most AVR owners. g. A deck with a 2V output can accurately track the original recording between 0V and 2V. 5K views 8 replies 4 participants last post by magoo Nov 25, 2007 Jun 15, 2023 · Higher preamp means your gains on the amp are lower and your not amplifiying any noise in the system as much. more sq oriented Click to expand This is the roots of a classic sales pitch for high-end audio. The Orion 250 HCCA I was using LOVED the Eclipse 8v signal. Turning up the gain has the possibility of introducing noise into your system, but as long as it's balanced with your input signal you should be fine. t3sn4f2 · Registered. 1's for the subs, and a MiniDSP C-DSP 8x12 for crossover and eq. But I've gone back and read the review again and 2V seems to be the unclipped pre-out level that can be obtained with amps disconnected. I've been using 2v and the only real difference I can see / hear is that it's not as loud (for a particular volume setting on my pre-amp). Amir considers an AVR that can put out 2V on the pre-amp to be kind of the goal. Feb 17, 2009 · Im looking to get a pioneer F90 or F900 nav unit. Apr 20, 2012 · It's relative. Nov 8, 2006 · I've had an Eclipse 8v, Premier 6. What is the advantage of having a 4V preout over a 2V? Is it worth it to buy a new headunit for 4V preouts? PS - Im running a Concept CD-2410 2400w rms amp at 1 ohm. Joined Jan 3, 2007 · 9,197 Posts #21 · Oct 8, 2010. The amp doesn't work any harder with the gain set correctly for a 2V input or a 4V input, it still puts out the same power. Basically, the higher the preout voltage, the less you'll have to turn the gain up on your amplifier. When I connected the CD player directly to a power amp with a 2v input sensitivity it would not get to full power, But still played pretty loud. May 31, 2004 · My head unit is has a 2V preamp outputs. com Dec 25, 2007 · Re-adjust gains for the output you want and call it a day. May 13, 2006 · Assuming that your amp can produce full power with the lower voltage inputs, there will be no difference between the output of the amp with a 1V input or 5V input. 5v, and Panasonic 5v. May 4, 2003 · I am looking into getting an Alpine CDA-9807 deck, and it has a 2v preout for the front and rear speakers and a 4v preout for the subs. There's no magical fairy that comes with high voltage preouts that somehow makes the 100w rms "sound" any better than if you were using a 2v preout. And also, in which proportion AVR owners use the HDMI input from PCM stereo source instead using the integrated DLNA player or the less prone to carry interferences/issues optical/tos-link (even coax). So we should first clarify that. In reality, the same noise is entering the system, but it's not getting amplified as much. 2-1. The higher voltage means the amp will use less gain to produce its rated power. "Don't worry about the pre-out voltage, and simply set the gains correctly for the amplifier on hand. Secondly, it has a huge inpact on dynamic range. Jan 18, 2011 · Thus say we have a input voltage of 2V, you could set it to 10, or if you had a 5V pre-out, you would set it to 4. 0V pre amps. 2V vs 4V on the same device, causes different sound signature, apart from the difference in volume? And of course, assuming both output incurs same level (or just inaudible difference) of noise and distortion. Obviously that'd be a lot of noise, but the point remains, that you will then amplify that noise at your actual amplifier. Jul 14, 2019 · Would the output voltage of a DAC, e. I don't get it! Perhaps the 2v from the CD player is at a low impedance, And the receivers input is so high it keeps the signal overload in check. . 5v anyway, so would the extra 2 volts be worth the extra 100 dollars? Jun 18, 2013 · If the preamp response doesn't change with loading, and if the power amp input impedance is flat with frequency, the ratio doesn't matter at all. i could hear a bit clearer etc. Jan 20, 2021 · The higher preamp voltage is there to minimize the effect of background noise. Preout voltage is only relevant for when you're connecting to amps via RCA. The higher the signal voltage is, the lower the noise level is in relation. A higher pre-amp voltage means better noise rejection. See full list on bestcaraudio. Thanks, TooFast Dec 1, 2020 · there's a big (and somewhat heated) debate going on over at the dcs. And yes the gain is set properly. Oct 25, 2007 · There's splitting hairs and there's a hair cut. ebanjnn zewwsx pmgnnb ahdbv jbzg qgeib xkwd floiz real lcebzx
