  1. XLS2500 - Power output vs AC consumption

    Subwoofer Amps | High Pass Filters
    Hi guys. I need an ELI5! How does a power amplifier that is capable of an output of 2400W RMS, only consume (from the print at the rear of the amp) 425W? I'm going to assume Crown have not invented a free power device - what gives? I understand that a switch mode D class can be efficient; but...
  2. Best Way To Measure Your System's Power Consumption

    System Setup and Connection
    This question popped up in a PM, now do you accurately measure your system's power consumption? I answered the best I could, which is copy/pasted below. There are probably other approaches... ======================== Power use is hard to measure, you have to get in series with the current flow...
  3. Power consumption versus power output

    Subwoofer Amps | High Pass Filters
    Hopefully this will get enough attention in this section... How are the two related? As in, if i were to put a Kill A Watt inline with my amplifier and it said 500 watts. Is there any correlation between that and output? I'm sure efficiency plays into it or something. Just wanting to learn...
  4. What is the real power consumption of the Pioneer VSX-921

    Home Theater Receivers | Processors | Amps
    Dear all, New to this forum, a happy newyear to everybody! I'm thinking of buying the Pioneer VSX-921 but am worried about the rated power consumption, being 500 Watt. A lot of the time, i'll simple be listening to the tuner through stereo speakers. Only rarely i would watch a movie at 5.1...
  5. HT Room Power Consumption

    AV Home Theater
    I added another subwoofer to my room and it has me thinking about how much power the room is using. Here are all the things in the room that take power and could potentially be on at the same time: Lights (9 @ 100W = 7.5A) PS3 (180W = 1.5A) Epson 8500UB (3.3A) Onkyo 805 (9.5A?) DirectTV DVR...
  6. Gizmo Power Consumption

    Remotes | Cables | Accessories | Tweaks
    Since this question comes up every now and then, I thought it might be helpful to sticky this info which is currently buried in another thread. Had a question the other day about how much power the Gizmo uses when on and/or in the standby mode. Didn't know the answer, so I picked up one of...
  7. power consumption for amps from the wall

    Subwoofer Amps | High Pass Filters
    I was reading the specs for behringer EP2000 it says it draws 1600W http://pro-audio.musiciansfriend.com/product/Behringer-EP2000-EUROPOWER-Power-Amp?sku=582001 The question is, it COULD theoretically draw 1600Ws if I crank everything up to unbearably loud levels right? But with normal using...

  9. Power Consumption Question

    AV Home Theater
    I have just been curious about Power Consumption of stereo amplifiers. When an amp is on, is the power consumption determined solely by the gain, or is it dependent on the actual sound level being sent through it. Say my sub amp is on, however I am listening to a song or movie soundtrack with...
  10. Power Consumption of AV Equipment: How much does it cost to run these things?

    AV Home Theater
    So, part of my Popcorn Hour A100 review was to compare the power consumption, and ensuing cost of operation, for the A100 vs a HTPC. So, I got my hands on a Kill-A-Watt and this is what I found... ----------------- (Item: Power Draw in watts) Popcorn Hour (Standby/Off): 5 Popcorn Hour (Playing...
  11. Power consumption / conditioning

    Remotes | Cables | Accessories | Tweaks
    I've been reading a little bit lately about green homes, and reducing power consumption, etc., and was wondering how much current most gear draws when it is turned off. I know most things still trickle a small flow, and some even have clocks, status LEDs, etc. Does it make sense to have all...
