  2. Anything dangerous about using very high gain??

    REW Forum
    I have a couple of nasty nulls in my room which I was able to correct with filters but I had to use gains ranging from 12-16. Aside from clipping which I can account for in my playback software by adding a negative gain to the overall signal, is there anything detrimental to using such high...
  3. Gain chain calculation

    Pro Audio
    Dear experts, I need help in calculating my gain chain in my active speaker system: this is what I want to achieve - remove the hiss problem - be sure that with the pre-amp turn to max I will not blow out my drivers - be sure I'm doing the right things... this is my system - Marantz SR7002...
  4. Gain controls

    Pro Audio
    I had a strange response from a Tech when I was picking up my Yamaha P7000s from Service today (for a failed Power Supply). The Tech asked me if I am leaving the gain controls up (since they were up when taken to the shop for repair), and I said yes, as it is in an active setup. He told me that...
  5. Adjusting input gain after calibration

    REW Forum
    First time trying to run REW. Sorry if this is a dumb question but my time is limited and I have spent countless hours trying to figure this out with no luck. After calibrating my sound card I am having problems getting 75db without either adjusting the input gain on my focusrite 2i2 or using...
  6. what can I gain from DIY

    DIY Audio
    I am making my 18 inch sub this will save me money. what I want to ask is other than the satisfaction what do i gain from making my own speakers. I am on a tight budget but have a very large room to fill 4000 cubic feet. I was going to get me some ascend 340's for the front and 170s for the rear...
  7. Confused with setting gain level on mic ECM8000

    REW Forum
    Hello. I have ECM8000 Behringer microphone which is connected to USB soundcard. So, when trying to measure a room, I am stuck at a point where I need to calibrate microphone. REW guide says that if I have a calibration file with sensitivity parameters I can skip this step. However, although I do...
  8. MiniDSP 2x4 gain for subs

    Electronic Processing/Equalization Devices
    So basically I got a flat response with minidsp, but, I pulled down my peaks so much that it squished the entire output. Now, my subs are really quiet. Tried to increase gain on the amp and increase output on the receiver but its not enough plus its picking up noise. I thought I could bump up...
  9. UMIK-1 gain loss problem

    SPL Meters | Mic's | Calibration | Sound Cards
    UMIK-1 suddenly shows very lowered noise floor: in quiet room, previously about -45 dB, now shows -75 Db or so, about 30 dB off. And it shows in the measurements (REW, also Holm), all are rejected as "low level" . The unit does react - the record meters "jump" - but the overall level is 30 dB...
  10. Crown XLS1000 gain structure help

    Home Theater Receivers | Processors | Amps
    Hello, I've read through Wayne's thread on how to properly setup the gain structure when using pro amps and have some questions. I'm using 2 XLS1000's connected to an Emotiva UMC 200 and have an noticeable hiss (easily 3-4 feet) through my 4 surrounds which is what's connected to these amps...
  11. The easiest portable gain knob

    Mobile Audio
    Hello all! My good morning/afternoon/evening to everyone.....first post here!! I am searching the easiest and cheapest way to add a gain amplifier into my car. The radio system has an Aux Input, but the signal coming either from ipod or iphone 4 is really low when diffused by the speaker. So...
  12. Help - what am I doing wrong? USB Mic gain on mac...

    REW Forum
    Just started with REW yesterday! First attempts at measurement seem to indicate something badly wrong with my setup, but I'm flummoxed. My Setup: MacBook Pro (OS 10.9.5) HDMI out to my receiver, testing one channel at a time as per these instructions USB UMIK-1 Sweep 0Hz to...
  13. Attenuating gain

    Electronic Processing/Equalization Devices
    I have the balanced 2x4 MiniDSPs, and now have amps without gain adjustments... Is there a way to attenuate the level for my horns with the MiniDSP? I need to attenuate about 12db. tia, Ron
  14. Implications of UMIK-1 shipping with -18dB gain?

    REW Forum
    I received my UMIK-1 mic last week and was a bit surprised to see that, as REW identified it as -18dB. I've read elsewhere that it seems that new UMIK-1 mics are being shipped with -18dB gain instead of -12dB gain. What would be the advantage for them to want to make this change to -18dB? And...
  15. Gain staging, which channel to output?

    REW Forum
    Hi all I'm using REW with output over HDMI, connected to my AVR. I have a MiniDSP connected to the subwoofer pre-output to equalize 2 subs. This works well, but I'm having some "challenges" with gain staging (as many others have, so I've read). So I'm testing what the maximum input level is...
  16. Stereo Amplifiers with Unity Gain

    Any Stereo Amplifiers with Unity Gain/AV Pass Through/Home Theatre Direct Input to suggest? Thanks
  17. Flat/Matte Neutral Grey's; N1-N10 and Gain

    DIY Screen Development and Testing
    I've seen bits and pieces of this information posted around, but never the whole thing at once and nobody really answered when I used to ask. So here's a simple chart that's useful for neutral Grey's and general brightness comparison. These numbers assume a flat/matte (lambertian)...
  18. Sub Gain

    I'm wondering how much gain you're cranked up to? Mine is at the 7th mark(9 is Max) on my PB12-NSD.I could crank it more but I'm trying to refrain! It's not quite hitting the Music Punch the way I like!
  19. pain(t) and gain

    DIY Screens
    Changed projector and it looks I need to paint again. Screen size is about 130"/ 2,35:1 and I have around 1000 lumens to work with. Last time as the base I used Dulux paint in vinyl matt finish: Dulux pain was "Ebony mists 5" / "Night Jewls 5" or in universal language, 00NN 62/000 / [N8.3]...
  20. PLIIz sub gain

    Audio Processing
    Hi, I wonder how many users of Dolby PLIIz are out there. Have those who use it ever noticed a considerable higher sub level compared to PLIImusic or PLIImovie? And if so, which receiver are they using? Curious how Atmos will behave in this regard.
