Has anyone tried out the external volume control with headphone jack device on routed games? I for one love hearing hearing the callouts, sounds, and music of the game while i play, so am a fan of the headphone jack. My location does trivia events and other things where they don't like loud playing games so this seems like a nice addition. But im wondering if the volume gets abused obnoxiously at times? If players turn it up too loud and bother other patrons. Im leaning towards a headphone jack over the bill acceptor as it can add more to the player experience than a bill can. But wondering if the external volume control is ok on public locations or if i should get just the headphone jack without external volume control. I also have a coin machine available on site.
