BDS PP-31 Green Digital Audio Spectrum Analyzer Display 1U Music Spectrum VU Meter 31 Segments

It’s a great light for your studio rack! I first bought the white version but decided to get the blue one and I’m glad I did. So if you are getting 2 the back has a xlr output to chain another with a xlr cable. It’s pricey but they sure look great! I got them for my radio station and people love it as it has that old school look and my station is a throwback station so they give it some o.g. Flava!They are also very accurate with music and you can adjust the sensitivity with the sound and brightness of leds. I just love being in the studio now and looking at the eye candy! Get some!!- Dj james

Good unit, metal housing,I used XLR connectors and did get a higher output on the lights so I turned down the sensitivity a bit, RCA connections will work fine too.THE camera would not pick up the true color of the LED's but the color is a real green, like GO green💚Keep in mind this is only light show, no eq level adjustments

I'm using this in my home music studio.The display is very responsive; many spectrum displays are a bit slow, so this is really nice.The dimmer control provides a good range. I did not require full brightness to be satisfied.There's a minor front panel labeling quirk; the dimmer control should dim as it is rotated clockwise. That's what would make it a dimmer. Instead, it increases brightness as it is turned clockwise. So it's actually a brightness control, not a dimmer. While a bit surprising at first, this in no way affects usability.The sensitivity control falls a bit short. At max, you can have audio going in that is perfectly listenable, with no indication on the display. At maximum sensitivity and a reasonable display excursion height, room filling levels are in play when the unit is used in a pass-thru mode.I'm driving the unit's XLR inputs with a secondary, adjustable gain source (a Behringer DS2800) and not using its outputs, so I can get past that issue easily; but if you're using it in a pass-thru mode where its outputs then are routed to your amplifiers, it's possible you might find the sensitivity range unsatisfactory.The unit consumes one standard rack space (1U) and uses a standard modular 3-prong (grounded) AC cord.Overall, a little pricey, but very informative and nice to have in the rack. For my use case, it's perfect.

So far so goodGlad the mounting ears are separate and rmovable, as are the screw on padded feet.Fed by my mixer, sensitivity is quite good and no frequency anomalies noted.I will do further testing in the next few days via the pre out from my NAD 3050 amp.

These things introduce a ground loop hum no matter how you plug it in and you cannot see the lights until you have the signal input all the way up. Don't throw your $ away avoid this poorly made item. I've never had anything make a humming noise in my system over 12 years of trying new stuff every other month.

Excellent spectrum analyzer. Accurate. Great as a display for the sound system to just see the bars move as a light show. Don't know how effective it is in a professional capacity but simply as a light show it is great!

Works as it should. Great display to help aging ears see what's going on.

Good quality, works as advertized.

No tiene prestaciones profesionales como un hold peak al menos y el tamaño lo hace difícil de leer. Este producto es más que nada para ponerlo sobre un reproductor de música común y se vea estético pues para un estudio es un juguete. Y como tal, su precio es excesivo para su casi nula funcionalidad.
