GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Most loudspeaker manufacturers recommend an amplifier with power output equal to the speaker’s Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating. The GX3 is ideal for speakers in the 300 watt (Program) range. The GX3 supplies maximum possible power to 4 ohm and 8 ohm loads.

Technical Notes
The GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the critical power transistors. A true Class B biasing system combines maximum thermal efficiency with excellent audio performance. QSC design expertise allows the output devices to shift from low-power to high-power rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss.

The amplifier uses premium toroidal power transformers for reliable mid-weight performance. A variable-speed fan moves air crosswise through the amplifier, drawing cool air in over the power transformer, through the fan, and then over the heat sink. This keeps the transformer cool and allows a full size heat sink to fit in a down-sized chassis. As always, the amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.

GuardRail
GuardRail protection delivers full peak power while preventing detrimental overloads. During excessive clipping, or extreme overheating, GuardRail reduces gain just enough to preserve the integrity of the music, protect the speakers and keep the audience excited, without unprofessional distortion levels or shutdowns.

Subwoofer/Satellite Crossover
A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX Series supports this mode with a Crossover switch that splits the full-range input entering Ch 1, sending 20 Hz -100 Hz to the sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel gain controls balance the sub and top box, while GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range.

Modal SKULPT | Analog Synth

Nemanja Acimovic

Vrlo zgodan mali digitalni synth, naravno ne treba ocekivati ludilo od njega s obzirom da je ipak dosta jeftiniji od analognih , ali zaista koristan i upotrebljiv. Zvuci vrlo ubedljivo sirom celog frekfentnog spektra. Mene je posebno privukao real time seqvencing-om i arpeggiator-om. Trebace vam malo vremena da se naviknete na kontrole s obzirom da svako dugme pomocu SHIFT-a ima duplu funciju, ali nakon samo par dana ce te bez problema biti u potpunoj kontroli. Treba reci da je dosta lagan i prilicno plastican, ali to je predpostaljam kompromis koji je napravljen spram cene. Uz njega ide i ModalAPP ili VST3 koj vam daje potpunu kontrolu nad svim funkcijama u vasem DAW-u ili na recimo telefonu. Moja ocena je 4- Radujem se sledecem izdanju ModalElectronic-sa mladjem bratu Skulpt-a, CRAFT synth-u.....

Numark Mixtrack Platinum DJ controller

Nenad Djordjevic

Nenadmasiv odnos cene i kvaliteta u entry / intermediate klasi. Ako mislite da sam suvise subjektivan, proverite sta kazu ljudi po netu. #1 kontroler u svom rangu apsolutno svugde, a pristupacan apsolutno svima. Svestrane mogucnosti, kapacitivni touch jog wheels kakve u ovom cenovnom rangu verovatno ne mozete ni da zamislite, multi FX kontrole (touch strip super radi, meni licno na VDJ platformi odgovaraju mnogo vise nego klasicni knob-ovi), 100mm super precizni pitch faderi, instant 4 deck kontrole, brzi trigger-happy performance padovi, sve u svemu u jednom paketu bez trzisno planiranih nedostataka i za vynil i za electronica DJ-eve (kucne i pro, bez blama). Jedina mana mu je, po meni, Serato lite bundle, ali izbor softvera je vec licna stvar. Prezadovoljan sam, cak i sa 99$ dodatnim troskovima za VDJ licencu.

KRK Rokit RP5 G3

Jovan Badnjar

Sjajni monitori po najpovoljnijoj ceni u gradu. Prezadovoljan sam kupovinom, odusevila me je sjajna stereo slika i kvalitet visokotonaca na Rokit 5-ici. Bas je utegnut i precizan ide do 45Hz sto nije najbolje moguce ali ne mozete ocekivati od 5" jedinice da pruzi najdublji moguci bas. Ekipa u Audio pro ekstremno prijatna i ljubazna. Sve pohvale!!
