LD Systems STINGER 8 A G3 Active 8" 2-way bass-reflex PA speaker

The new J series is a technologically advanced range of products that improves on the performance of the previous Jolly line.  The new J series is a competitive, value for money range of speakers.
The range is based on the development of three new high efficiency class-D amplifiers with power specifications of 350 + 100W for the J 15A & J 12A, 200 + 50W for the J 8A and 80 + 40W for the J 5A. 

These amplifiers have been designed \'from the ground up\' in FBT’s R&D laboratories.
The largest amplifier model that equips the J 15A and J 12A has a switch mode power supply as well as a digital signal processor with 4 pre-sets. The J 8A and J 5A amplifiers have toroidal transformer power supplies. The J 8A has a digital signal processor with 2 pre-sets, whilst the J 5A has analog signal processing. The speakers have been completely redesigned, introducing the technological developments of recent years to achieve a far superior efficiency and linearity.

Following from the new J series, FBT bring you the DJ 15A, designed with today’s modern DJ in mind.  The DJ 15A has invaluable features allowing quality audio playback using our revolutionary DSP technology.  This includes 4 presets enabling the DJ to change the sound of their music to suit the environment they play within.

These DSP presets will allow the DJs audience to enjoy improved sound quality and SPL, especially in bass reproduction at high volume.

The DJ 15A also has another useful feature for DJs, including a two channel input mixer allowing the DJ to plug a music source and microphone direct into the speaker, giving separate control over volume for both devices.  You can also daisy chain these speaker together if required.  Ideal for many application of today’s modern DJ.
