Crossing Over Frequencies?!

Have you always been curious about the gigantic speakers in the Pi room? Aidan looked into utilizing these speakers and found that they need an audio crossover to work.

What is a audio crossover you may ask(I asked)?

It is a technology that divides a full-range audio signal into its high, mid, and low frequency components, then sending each speaker the appropriate frequencies that it is designed to accurately reproduce.

After some digging in the ElectronicaLab, Raffy found a Carvin XC3000 Crossover. We tried to connect it to the JBL speakers in the good room, but realized that we need 4 XLR to 1/4’’ F to M cables, 2 for each speaker’s high and low frequency. Unfortunately, we only found 3 of them, and buying a new one would cost about 25 dollars. Fortunately, we found the appropriate connector parts on the parts wall to perform gender swap surgery on the XLR to 1/4’’ M to M cables.

Crossover is finally working now!!

The Setup

There was a very obvious change in audio when we adjusted the low/mid and mid/high frequency selector knobs on the Crossover.
