Hi, my PA amplifier has the double watts RMS needed for my speakers, so I put the gain knob -3db. I started using Equalizer APO as a DSP for my sound system, and I want to have the knobs on the amplifier all the way up and put the -3db gain in the pc. But it's not the same, I tried to match the volume, and I ended up putting -6db to -10db in equalizer apo, someone can explain why?
How much -DB I put on Equalizer APO to match the -3db on the PA amplifier?
Thanks...

Say Your amp outputs 100W with a 2V signal. If You feed it with a 1V signal, it will output -3dB. What's Your 0dB PC output signal ? 1V 2V 5V ?
You have to set the -3dB on the PC but then use the main volume to match the 1V signal. If the amp has a VU it's simpler. Adjust the volume until the -3dB led lights.

Boas, é Português??
Eu tenho amplificador de som PA, só tem mesmo os botões dos DB, e a parte de trás do amplificador, onde uso 1V de entrada de sinal. uso uma focusrite scarlett solo como placa de som. Eu uso o (Equalizer APO) como crossover, equalizador, etc...O problema é que os (-3db) no botão do amplificador não equivale aos (-3db) no pré amplificador do Equalizer APO, no qual tenho colocado entre (-6db a -10db). Secalhar o Equalizer APO utiliza uma medição de DB diferente.
Good, is it Portuguese ??
I have a PA amplifier, I only have the DB buttons, and the back of the amplifier, where I use 1V signal input. I use a scarlett solo focusrite as a sound card. I use (Equalizer APO) as a crossover, equalizer, etc ... The problem is that the (-3db) on the amplifier knob is not equivalent to the (-3db) on the Equalizer APO preamp, which I have placed between (- 6db to -10db). Underlying the Equalizer APO uses a different DB measurement.

Why? What are you trying to achieve?Hi, my PA amplifier has the double watts RMS needed for my speakers, so I put the gain knob -3db.
"-3dB" only affects Gain, not maximum output Power, by any means.
Please state Amplifier Brand and Model; a direct link to user manual would be even better.
Same question as above.I started using Equalizer APO as a DSP for my sound system, and I want to have the knobs on the amplifier all the way up and put the -3db gain in the pc.
Hard to answer unless we clarify the doubts above.But it's not the same, I tried to match the volume, and I ended up putting -6db to -10db in equalizer apo, someone can explain why?

In any case, matching volume by ear is quite inaccurate.
