Monitor Speaker & Power Amplifier
1. Stage Monitor Speaker (Calculating Impedance)
250W/1000W/8 ohms Monitor Speaker
TRS: Balanced
TS: Unbalanced
반드시 TRS로 Balanced 시그널로 전송.
Dial on Peavy 112TLM: Knob used to adjust the tweeter
Tweeter for high frequencies
Woofer for low and mid-range frequencies
Calculate the combined impedance of all speakers used each amp channel
Impedance of one speaker / Total number of speakers
(Assuming all speakers are the same)

중요!!!
White Noise?
Caused by the gain, or amplification, turned up too high at some point,
Why am I hearing noise in my studio monitors?

2. Power Amp
Need amp that can produce at least 100 watts per channel into an 8-ohm load
All About Ohms: Ohms - Measure of Resistance
Set-Up: Two speakers per amp
Two 8-ohm speakers running in parallel = 8/2 = 4 ohms
"Take the ohm rating for the speakers and divide by the number of speakers."
Quick Reference listing of Commonly Used Parallel Loads:
Two 16-ohm speakers = 8 ohm
Two 8-ohm speakers = 4 ohm
Two 4-ohm speakers = 2 ohm
Three 16-ohm speakers = 5.33 ohm
Three 8-ohm speakers = 2.67 ohm
Three 4-ohm speakers = 1.3 ohm
Four 16-ohm speakers = 4 ohm
Four 8-ohm speakers = 2 ohm
Four 4-ohm speakers = 1 ohm
