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)

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
