Sound Machine vs. Voice Machine

Posted by Curious on 9/4/2025, 4:19 pm

I have two Sound Projection Voice Machines. I am not getting what I would consider a decent range out of these units. On a good day, I get only a little bit of sound loss from a distance of about 150 feet in open space from the bleachers to the middle of the field. The signal is just not reliable.

I've seen many schools using the Sound Machine instead of the Voice Machine, but the mics and body packs look to be the same. Are they different/better on the Sound Machines? How have they performed for your groups during rehearsals and in the stands at games?

Cell phone signals will cause interference. During a game, if your coaches are using wireless headsets to talk to the pressbox, they will interfere as well.

I have both and found them to exactly the same. The Sound Machine is a much better quality in terms of audio but that is by design. Make sure you are scanning often and have the antennas out and up at a 45 degree angle like this

If you are having to transmit through people you will have problems, get the speaker up on a speaker pole as high as reasonably possible. Wear the pack in a shirt pocket or belt clip towards the receiver.

Voice machine is a horn. Sound Machine is a speaker.
