Brien - using Bob Gold's calculator, how do I calculate a room of varying widths?

I'll be more specific ... I'm looking at moving into another area of my house - it's a Living Room area - where in half of the section, a staircase cuts into the width by 3 ft.

I am trying to calculate/meter the total load I am showing the pickups, but I'm a bit confused. I have a few mods in there to alter the sound of the pickup. The pot is 500k and wired with hot lead to lug 1, lug 2 is output and lug 3 is bent back and soldered to the base. I have 333k resistor and 1000pF cap between lug 1 and lug 2. I also have a 1M resistor between lug 1 and lug 3.

Is there some formula to calculate the adjustment of delay necessary between the main pair and spot microphones, i.e. x milliseconds of delay for y distance?

I believe the other technique is to clap hands in front the spot microphone and use the wave editor to line up the spike between the mains and the spot. Is this correct?

Does anyone know the formula for calculating total AMPS? For example if you add up all your gear's maximum wattage and say you come to 1,000 watts, how many amps is that?

I know you're also supposed to add 10% of buffer to prevent overloading the circuit.

Hi,

This is my first posting so bear with me.

Just bought a Peavey Power Amp for Live Band use. It is rated at 2000W RMS going into 2 ohm speakers, and 1300W RMS going into 4 ohm speakers.

We're using 8 ohm speakers, so what does that make our RMS rating?

Thanks in advance.

Hi everyone, Im new here (so hopefully Im posting this in the right place/want to apologise in advance if Im not...)
I want to calculate the degree of phase shift between two sine Wavesof the same frequency. I have the following formula (but cant find the right symbols on my keyboard (!)):

degree of phase = time difference * frequency * 360

Help please?
