THE camera would not pick up the true color of the LED's but the color is a real green, like GO greenπŸ’š Keep in mind this is only light show, no eq level adjustments Review: AWESOME EYE CANDY FOR YOUR STUDIO!🎡 - 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!

You would just run the RCA out from the source to the spectrum analyzer, then the RCA out from the analyzer to an input on the receiver. Ideally, you want your receiver to have pre-out and pre-in connections, where you would run the pre-out to the spectrum analyzer, then spectrum analyzer's out to the receiver's pre-in. Then it would work for all sources inputting to the receiver. **Q: If this device is switched off, is the audio signal still passed on?** A: No, the device passthrough outputs turn off too. Best you can do is turn the sensitivity all the way down and leave it on if you need the passthrough. **Q: Item shows choice of green, blue and white leds. can the led color be changed?** A: No, the lights cannot be changed. You would have to buy a unit that comes in that color. The only things that you have an ability to change are the brightness and sensitivity. **Q: Can you switch the display between left and right signals? Or would I need two of these to monitor both left and right signals?** A: The PP-31 mixes the two inputs down into one. There is no switch to display each input separately; you'll need two PP-31's to do that. ## Customer Reviews ### ⭐⭐⭐⭐⭐ BDS PP-31 *by R***Y on January 18, 2025* 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 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. ## Frequently Bought Together - BDS PP-31 Green Digital Audio Spectrum Analyzer Display 1U Music Spectrum VU Meter 31 Segments - ADJ Products DB Display MKII DJ Mixer - Cable Matters 2-Pack Premium XLR to XLR Cables - 6ft, Male to Female Microphone Cable, Oxygen-Free Copper (OFC) Mic Cord, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/428304536-bds-pp-31-green-digital-audio-spectrum-analyzer-display-1u](https://www.desertcart.tn/products/428304536-bds-pp-31-green-digital-audio-spectrum-analyzer-display-1u) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-06*
