Review on 🔊 B&K Precision 3001 Sine/Square Wave Audio Generator - Versatile Frequency Range Ideal for Audio Testing by Ian Bates

I like that this audio generator has a variable output level. It also has a battery indicator that lets you know when the battery is getting low. It comes with a cord with alligator clips that will do most jobs. I use this to create tonal tones for testing room acoustics, so the full range from 20Hz to 20kHz is comfortable. I also only used it to test the speaker, but it produces a lot of sound. It was interesting to scroll through the frequencies and see where the speaker performance dropped, in my case it was around 50Hz. It looks quality and comes in bubble wrap and a nice box so it's on its way from the seller to was well protected. I think it will take a long time.
