JB SYSTEM - DSPA 1500

Amplificatore Professionale dotato e controllato da DSP

Progettato con l'efficiente tecnologia in classe D,garantisce alta erogazione anche su 2Ω

Perfetto per installazioni fisse - tramite processore è possibile impostare crossover, equalizzatore, limiter senza l' utilizzo di apparecchiature esterne

Stereo: 2x 440Wrms @ 8Ω ~

• 2x 750Wrms @ 4Ω ~
• 2x 1200Wrms @ 2Ω

Bridge: 1500Wrms @ 8Ω ~

• 2400Wrms @ 4Ω

Perfetto per installazioni fisse(pubs, shops, hotels, restaurants, … ) così come per DJ Set

Il DSP (processore digitale di segnale) comprende:

• HPF: (40~125Hz) eliminates unwanted, energy absorbing frequencies.
• LPF: (6.3k~20kHz) cuts the upper frequencies if needed to avoid oscillations.
• 8 Band parametric EQ: (100Hz~12.5kHz, Q:0.5~5, ±6db) for perfect tuning.
• 2 Limiters: for increased protection (threshold 0~-12dB).
• 2 Delays: can be set separately from 0 to 20ms (0 to 6,86m) for each channel.
• Crossover: build an active system (Linkwitz-Riley 24dB/oct, 50Hz~3,15kHz)
• 3 working modes: Stereo, Bridge, Input Y (mono in, used for active system)
• Temperature controlled fan cooling
• DC fault + high temperature + overload + short circuit protections
• Balanced XLR + jack inputs with possibility for daisy chaining of several inputs.
• SpeakON® + bind-post wire terminal outputs
