am urmatorul amplificator:
SOny ES XM-3046
-30W x 4 RMS at 4ohms, 20-20kHz, at 0.04% THD (12V)
-45W x 4 RMS at 2 or 1ohm, 20-20kHz, at 0.1% THD (12V)
-1ohm Drive low impedance operation, even at 12V
-40W x 2 + 120W at 4ohms, 20-20kHz, at 0.1% THD
-120W x2 at 4ohms, 20-20kHz at 0.1% THD
-Discrete FET predriver stage
-Discrete final state w/ MOSFET audio devices
-Independendant supply rails for predrive & final stage
-Regulated MOSFET power supply
-50/80 Hz selectable 18dB/Octave low pass filter
-80 Hz selectable 12dB/Octave high pass filter
-Protection for temp, voltage & current faults
-Balanced input circuit for noise isolation
-Cooling fan with DC brushless motor
-Chassis mounted gold plated RCA & screw terminals
-Detachable end caps conceal wiring and connections
am nevoie sa fac acei 120x2->240x1 pentru un sub de 300w
cum pot face un amplificator pe 4 canale sa mearga pe unul singur?
