musicbook:55 Pojačalo snage
             

Musicbook:55 je potpuno balansirano stereo pojačalo snage u D klasi. Bazirano je na više patentiranih rešenja, a posebno na tehnologiji UCD pojačanja. Potpuno diskretna topologija i pažljivo optimizovana primena najkvalitetnijih delova postižu neprevaziđenu detaljnost, dinamiku i prirodne boje muzike. Može biti konfigurisan kao stereo pojačalo, mono bi-amping pojačalo i mono u "bridge" modu. U svakom režimu rada, ima dovoljno snage i kontrole da iz svakog zvučnika izvuče maksimum. Glavne osobine su:

-Balansirano pojačalo snage u klasi D
-Izlazna snaga 2 x 240 W ili 1 x 450 W, na 4 Oma
-Diskretna konfiguracija
-Patentirana UCD tehnologija
    
    KARAKTERISTIKE:
    
     Protection circuits
  • DC at output: power supply cuts out.
  • Overtemperature: amplifier goes into mute until the temperature has dropped by approx. 10 °C.
  • Output current limiter: amplifier goes into mute for ca. 0.25 seconds. Switching threshold 15 A peak. In case of continuous overdrive the amplifier will go on and off several times in a row.
     Automatic turn-on
  • Input signal switching threshold: approx. 0.5 mV.
  • Stand-by mute mode: power supply active, amplifier muted. Power consumption 2.50 W.
  • Stand-by sleep mode: only stand-by power supply active. Power consumption 0.45 W.
  • Active mode: power supply and amplifier both active. Power consumption depending on volume level 20-30 W average, 600 W max. peak power.
  • Turn-on times: approx. 2 seconds from stand-by mute mode to active mode; approx. 8 seconds from stand-by sleep mode to active mode.
  • Turn-off times: after 20 minutes the amplifier will return to stand-by mute mode, after another 20 minutes to stand-by sleep mode.
     Power Amplifiers
  • XLR inputs: analog line level inputs with 10 kOhms input impedance.
  • RCA inputs: analog line level inputs with 5 kOhms input impedance.
  • Speaker outputs: safety banana lab sockets (4mm) for connecting loudspeakers with 4–8 ohms.
  • Output power: 240 W into 8 ohms per channel (<1 min).
  • Maximum output current: 15 A peak. 
  • Gain: 25.8 dB (20-fold).
  • Frequency response: 0 Hz – 36 kHz (-3 dB).
  • THD & noise: <0,05% typ.
  • Radni napon: 90–264 V, 50–60 Hz
  • Dimenzije: 280 x 220 x 65 mm (W x D x H)
  • Težina: 3.70 kg
  • Potrošnja: 0.5 W standby, 14 W mute, 500 W max.
