12" Powered PA Speaker - Bi-amped - 150W + 30W RMS
The PBO-12BM is SWAMP's all-round workhorse PA speaker, with a bi-amped design, Bluetooth and TWS connectivity. Featuring 2 direct inputs for microphones and 1 line level audio input, 2 band EQ control, 180W RMS / 360W MAX of power in a monitor / foldback option speaker box. This speaker will provide a clean high-end presence, with a tight full bottom end.

FOH or DJ Speaker
The PBO-12BM delivers power of 180W RMS (bi-amp configuration), 360W at peak levels. A pair of PBO-12BM offers plenty of thump for small pub and bar gigs, up to 120 people. Mounts on all standard speaker stands. A slanted speaker box design allows the PBO-12BM to be used effectively for stage monitoring applications. 

Bi-Amped - 150W + 30W RMS
Built with a bi-amped configuration that utilises two individual amplifiers to power the woofer and the tweeter separately, making the amplifiers much more efficient resulting in more volume per watt. Using a carefully designed crossover (splitting of frequencies between the Tweeter and Woofer) ensures a clear mid range and present, but non-piecing top range. All the while layered with a fat bass sound from the 12" woofer, that can be EQ'd to your preference.

Ins and Outs
The inbuilt mixer module makes it possible to connect 2 microphones via a dedicated XLR Mic input or a jack input. A decent preamp and gain control supports the sound of your microphone. As well, there is a line input, with both XLR and RCA connections. All inputs have individual level controls. Dual RCA inputs are included to connect a DJ mixer or CD player, while the XLR Line Input enables a Balanced Line Level signal from an external mixing desk to be sent to the speaker. There is also an XLR/Jack line output, giving the ability to daisy chain the signal onto another speaker.

Bluetooth Connectivity, TWS and MP3 Player
On the PBO-12BM, you will find bluetooth connectivity for wireless control of your audio playback. Simply activate bluetooth on your Smartphone and select the speaker for instant playback of your phones audio. Perfect for lining up music to play before and after a set. The module also allows for a USB flash drive or SD card to be used for MP3 playback. In addition, the speaker comes with a remote control.

When you have two speakers, you can connect them as a wireless stereo pair. Simply turn on the two speakers, switch to Bluetooth mode without any connection, press and hold the TWS button on one of the units which will then become the Left channel, and the other unit becomes the Right channel. This will be shwon on the display. After the TWS connection has been set, use your mobile device to search and connect to Bluetooth, and the Left channel unit will show ' connected' on the display, and the two speakers will playback music in true stereo.
Hold the TWS key again to disconnect TWS.

Great PA speakers. The great price is just a bonus. Very happy with the functionality but more importantly, the sound.

Swamp PBO-12BM Speakers

Well, after waiting for 4 months due to Covid, I finally had the chance to try my new Swamp 12" active speakers. My vocal-based band played for a couple of hundred people in the courtyard of a local club to celebrate the Melbourne Cup. The speakers performed flawlessly; no noticeable white noise & the speakers were more than we needed volume-wise. The speakers projected clear sound with good articulation and balance. Highly recommended. Service from Swamp was also excellent after one speaker went temporarily AWL (due to couriers).
