In order to get a feel for the signal levels suitable for the HD500, I've made a few measurements of the gains available from the different inputs to the various outputs. I've also measured the gain of all the FX. A small Excel spreadsheet containing the data can be found here (unfortunately, I can only upload a PDF version of the data, which I've done here). A brief summary is shown below: All measurements were made at 1kHz with Master Volume = max, S/PDIF gain = 0dB, and Input2 = Variax (although this didn't make any difference because I had Inputs 1 & 2 panned hard Left/Right). Guitar input pad = -5.2dB compared to normal. 1/4" (line) output has 6.1dB more signal than 1/4" (amp). Aux & Guitar (normal) have the same gain structure (except Guitar has programmable input impedance). Guitar (normal) input to 1/4"(amp) output has 4.9dB of loss with no FX, no Amp, and Mixer = 0dB. Compared to 1/4" (amp) output, the XLR output is 9.4dB less while the phone output is 15.4dB more. Compared to the Aux/Guitar(normal) input, Mic (min gain) has 6.2dB less gain while Mic (max gain) has 38dB more gain. Aux/Guitar(normal) input clips at 0dBFS (measured at S/PDIF) with 8.3Vpp Mic (min gain) input clips at -1.1dBFS (measured at S/PDIF) with 14Vpp Mic (max gain) input clips at -1.1dBFS (measured at S/PDIF) with 91mVpp CD/MP3 input clips at various levels near 20Vpp, depending on which output is used (XLR, 1/4", or Phones) By far most of the FX have 0dB of gain, but there are several exceptions (e.g., Graphic EQ = 2.9dB, Tape Echo = -5dB, and others). FX were measured with Mix=0% (to eliminate comb filtering effects) and Gain=0dB (usually). The PDF files contain the whole list. Using some of this data you can see the clip level is essentially set by digital clipping, although the mic input stage only gets you to within 1.1dB of fullscale (close enough to call it fullscale in my opinion). The output stages will not get close to their clip levels (unless you use the CD/MP3 input which bypasses the digital engine). That is, it's sufficient to look at the S/PDIF signal to keep your signal below fullscale. You don't have to worry about clipping the input stages. You also don't have to worry about clipping the analog output stages. I hope you find this useful in optimizing the setup of your equipment. IO Gain.pdf FX Gain.pdf
I've been reading about the volume issues with the DT50 212. Too loud, etc. Before I say anything else its the real deal amp. I'm blown away with the HD500 integration. The Solo models are to die for!!!! Here's what I do to deal with volume issues: Each amps output can be set to the expression pedal without using DSP. Watch for how to do this. I've taken my amps/tones and used this technique to lower the overall volume (around a maximum value of 50-60) while keeping the master volume on the high power position (pushed in). Keep the master at about 12 o'clock (or what you like) and use the output settings to level each amp (patch) to each other and to lessen the output. This can be done with dual tones as well, just set both amps to similar parameters, and same expression pedal. Do you lose sound? At 50-60 ... no on most amp models. Some amp models lose slightly, but low volume is merely, usually practice. Is this the perfect fix? Probably not. However, your amp/patches will be leveled, properly loud, and get full use of channel volume and master volume mixes. When playing live a quick touch on the master can work wonders. Let me know how this works out if you try it. His advice (see link above) for wah pedals is spot on too. If its too loud ... move! LOL Happy jamming! bribrew1968
Vetta II Post Delay Mix Issue On some patches with POST DELAY active, you will notice that if you turn DELAY off/on, the perceived mix will jump to %100. Please follow the steps below when the problem patch is active to resolve this issue: Select FOOT CONTROL. Scroll to Page 4 that say PEDAL 1. Use the black knob under DEST to assign PEDAL 1 to a different parameter (an fx you are not using on the patch), Go to page 5 and if PEDAL 2 is set to POST DELAY MIX, follow the same instructions above. Select SAVE twice to save the changes. Gain/Drive Reversal When Using Line 6 Edit Drive and gain for distortion effects are reversed when loaded into Line 6 Edit: After loading a tone or changing the model selection, the drive and gain values for distortion effects are reversed when comparing the amp display to Line 6 edit. When adjusting the drive or gain using Line 6 Edit or the amp, the correct control moves and jumps to match the value of the one you are moving. This effects all distortion effects, and also happens when loading a tone.
