JBSYSTEMS DSPA-1000
Professional DSP-controlled switch mode power amplifier.

DESCRIPTION Professional DSP-controlled switch mode power amplifier. The high efficient class-D design guarantees high power, even at 2Ω! Stereo: 2x 300Wrms @ 8Ω ~ 2x 500Wrms @ 4Ω ~ 2x 750Wrms @ 2Ω Bridge: 1000Wrms @ 8Ω ~ 1500Wrms @ 4Ω Perfect for both DJ and install applications (pubs, shops, hotels, restaurants, … ) Complete DSP-section with: 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 TECHNICAL INFORMATION Power stereo 8Ω (1kHz, THD+N 1%): 2x300Wrms Power stereo 4Ω (1kHz, THD+N 1%): 2x 500Wrms Power stereo 2Ω (1kHz, THD+N 1%): 2x 750Wrms Power bridge 8Ω (1kHz, THD+N 1%): 1000Wrms Power bridge 4Ω (1kHz, THD+N 1%): 1500Wrms Freq.
