Hi all,
Does anyone know the peak frequencies of dual tone Alertronic controllers? Potentially also the start frequency.
Thanks.
All the drivers do is reproduce the sound fed to it through the amplifiers (themselves fed by the tone generator) into whatever chamber the sound will emit from (a reentrant horn, a speaker chamber in a stereo, etc.). Far more goes into how a tone (or music or whatever) sounds than just the frequency. Horn/speaker resonance is one thing (think why different speakers sound, well, different) but, more importantly for tone generation, so is the shape of the wave. Go look it up. Siren tone generators are really nothing more than primitive simple synthesizers so many of the principles translate.
For real? Wow. I always thought they would have used a pulse or square. Also surprised they use a triangle over sine, but oh well, it works. Guess you don't want to blow the drivers. Thanks for the help!SuperBanshee836335 wrote: ↑Wed Jul 28, 2021 3:24 amThey actually use a triangle wave with varying tones for all electronic sirens (Except Whelen, which uses square)
This is incorrect. It’s all square.SuperBanshee836335 wrote: ↑Wed Jul 28, 2021 3:24 amThey actually use a triangle wave with varying tones for all electronic sirens (Except Whelen, which uses square)
