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

The BDS PP-31 has good build quality, accurate metering and is a solid addition to any rig in broadcast or podcast studio.

This hard to find, spectrum analyzer only, unit seems a little overpriced - product of the supply / demand ratio I guess. If you want ground protection, do NOT use included power cord - outlet side connector is only 2 prong, 6A 250V rated, while unit side is 3 pin, 10A 250V. FYI - the unit has connections to all three pins for the input power (L, N, and ground to unit chassis). I went with a Goalfish power cord (prime next day ship). The unit I received looks different from one pictured in description (better) - The brackets for mounting in a rack are NOT part of the main unit (all labeling is present on front panel and unit can be set on a shelf), loose brackets are included, and screws are present in mounting holes on side of unit. As reported by others, the "dimmer" knob should actual be labeled "brightness", and the "sensitive" knob only adjust bar graph on display, NOT output volume. If the analyzer is too distracting or not needed, the unit can be switched OFF with no effect to signal running through it (I've only used RCA in/out connection).

Power cable is so wrong and is a possible hazard. Instructions are hilariously unintelligible. Lack of serial number is suspect.

Works perfectly, down loaded a frequency generator for my iPad and this responds right on for each frequency, very happy with it and super easy to hook up, and looks great.

Loving this! The look is very cool! Easy to set up and add into the rack! Adds a sweet and pro look to the rack!

Ok quality. but I returned it because the 40 and 50 Hz LEDS do not respond as they should using a frequency generator. This is a cheap duplicate of the one made by Fun Generation(RTA-31) sold at Thomann. Much cheaper at Thomanns too!

It works more or less.
