How do you delaying second set of speakers,

[@whco-rrn8459]

San Saechao I would suggest using a dedicated delay in the output line before the second set amp. You want to have un-amplified signal going into your delay. If you have amplified signal going into your delay, you will most likely lose the dedicated delay so make sure that the input to the delay is not from an amplifier. There is some math to setting the delay. You have to measure the distance from the primary speakers to the secondary speakers. Check out this link for the formula for setting the delay in milliseconds. The formula is in meters and the air temperature is in Celsius. Use the appropriate conversions. Then test using your ears.
