Boxe active LEM D400 DSP

Vand o pereche de boxe active made in Italy, LEM D400 DSP, 400W / RMS (300W woofer si 100W driver), difuzoare SICA de 12" pe neodymium in 4ohm. Boxele arata foarte bine si functioneaza le fel de bine. Nu au fost arse, rebobinate etc. Au un bass foarte bun, se poate duce lejer un botez sau nunta de 50-60 de persoane doar cu ele. Sunt ideale pentru a echipa un pub, terasa, bar...

Mai multe detalii tehnice gasiti pe internet. Motivul vanzarii este ca vreau sa trec pe active de 15" ( RCF, FBT, JBL). Pretul este de 500 euro, ambele. Nu se vand la bucata, doar pereche!

Nu licitati inainte de a intreba despre disponibilitatea lor. imi rezerv dreptul sa vand aceste boxe si pe alte site-uri de profil. Acord calificativ negativ celor neseriosi care liciteaza si nu cumpara. Prefer predarea personala pentru a se asigura proba la fata locului. Nu trimit in tara celor care nu au minim 25-30 de calificative pozitive decat cu plata transportului in avans (tur-retur)!!!

Schimb decat cu o pereche de boxe active din cele mai sus mentionate, cu diferenta din partea mea. Cateva specificatii tehince:

LEM is proud to announce a breakthrough in the field of professional loudspeaker systems.
For the first time the digital processing technology, up to now only used for high-end products, is available in a loudspeaker system designed for musicians, DJs, clubs owner's and audio technicians, with a price within everybody's reach.

The new D400 combines to the most advanced solution as far as the cabinet construction, the speakers and the power amplifiers are concerned, an extremely powerful digital processor able to provide performances up to now impossible to obtain in this range of products.

D400 is housed in a cabinet made of plastic material (high-density polypropylene), which provides a very light weight and a stylish design.

The speakers used, from the 1" compression driver with titanium diaphragm to the 12" woofer with neodymium magnet, guarantee high performances and an exceptional sound quality.

The built-in power amplifiers have been designed without compromises, in order to offer a big dynamics and an output power with no tricks.

Finally, the digital processor with 24bit, low-noise conversion system and 40bit processing power, is able to perform with very high precision all the processing features needed for the best acoustical performances: from the high-precision EQ and crossover filters to the delay lines for the speaker alignment and the multi-function digital protection system for the maximum speakers durability and reliability.

Key features

- 1" compression driver with titanium diaphragm, mounted on a high-efficiency CD horn with wide horizontal and vertical coverage (100x60°)
- 12" high-excursion woofer with 2.5" voice coil and neodymium magnet, which provides a great weight reduction for the easiest transportation and installation

- Combo input connector able to accept both line and microphone signals, with XLR-M connector for the signal linking
- 2-way digital processor with HPF and LPF XOVER filters on each output, 5 EQ filter on the input and on each output, delay lines for the speaker alignment, phase adjustment, additional processing Plugins (Multicomp, Noise Gate, Hum Cancel and Anti-Feedback)
- digital protection system including peak limiter with anti-clipping function, long term power protection and frequency-sensitive compressor for the low section
- 16 presets selectable from the amplifier panel, including different EQ and configuration setups
- also available in passive version (x300) with 300W power handling
