Alright, rarely do I ever get excited about a business or education projector’s audio quality, but ViewSonic did something cool here! Usually, these types of projectors will have either a mono or stereo speakers built in, and the internal speaker(s) are always lacking in bass and any sort of proper compression or EQ. I always tell people to use external speakers, which Art gets on my case about (sorry, not sorry, I’m an audiophile, no matter what the application). In the case of the PS750W, ViewSonic has included what they call SonicMode, which is enhanced audio performance.
A built-in DSP chip (Digital Signal Processor) is to thank for this. There are three different modes so that you can get the right sound from your content. Those modes are Standard, Speech, and Entertainment. Those last two are designed to tweak the audio to sound best for presentations and video content, which is more than I can say for other classroom projectors! Paired with the dual 10-watt speakers, the PS750W is a force to be reckoned with. I’ll talk some more about my experience with the audio on the Picture and Sound Quality page later in this review.
