Maxell MP-JU4001 Laser Business Projector Review – Performance: Brightness, Image Noise and Audible Noise


The Maxell MP-JU4001 brightness is rated at 4,000 ANSI lumens by Maxell. Even though our test results are not 100% in line with this claim the brightness performance of this mid to small size 3LCD laser projector is very good.

So the big question you’re waiting for the answer to is coming. How did the MP-JU4001 actually perform? How close to Maxell's brightness claims did it perform? As we normally do here at Projector Reviews, we measured using the projector’s brightest mode (Dynamic) at full wide angle – this is with the iris wide open, so the most amount of light gets through. I took 3-4 readings about 15-20% out from the center of the lens. That should give a good approximation of ANSI lumens.

The MP-JU4001’s Brightness (Dynamic mode, Normal Light Output): 4617 Lumens

At wide zoom, Dynamic mode. The JU-4001 measured 4617 lumens which is 617 Lumens above to Maxell's brightness claim of 4000 Lumens. For the rest of the modes, I measured them at mid-zoom, so the iris is closed halfway. This is because it is more common for a projector to be zoomed in a bit rather than installed at full wide angle.


I did this review sitting about 4 feet behind the projector. While reviewing content with the sound coming through the built in speaker, I couldn't hear the projector fan running. If the sound was turned down or off I could hear the projector’s fan but it was actually relatively quiet. Maxell doesn’t provide a decibel rating for noise in the documentation I have, so here is my unscientific assessment.

A slight fan noise can be heard but wasn't noticeable when video was being played. When it comes to being placed in a conference room or a classroom it's just not going to be a problem regardless of placement, unless it's in your lap. Bottom line, this projector is quiet and, in my opinion, not going to be an issue for your customers or their students and/or meeting attendees.


The MP-JU4001 has a single, 16-watt built-in speaker that can play loud enough for use in a small-sized conference room. While the sound is OK for voice narrations, it is less than ideal for playback of video tracks where music is important.

Overall the sound quality is comparable with other competitive business/installation projectors with built-in speaker(s). If higher quality audio is desired, the projector has a variable level 3.5mm output jack that can be used to connect it to an external powered speaker system.
