PA-B power amplifier series feature: 1) Protect the circuit when higher temperature, larger input signal or overload. The radiator-fan moves faster when it alarms by sound and light 2) Balanced input expands signal transmission distance and improves its anti-jamming ability 3) The user can force it to switch to the signal input priority end to carry out emergent broadcast by short circuit or DC24V forced switch 4) Gain input adjusting freely is available for the user 5) When AC is in a fault, the equipment will be made to go on running by backup power supplying system 6) Internally fixed with scheduled system for starting the machine or turning it off. 7) Digital communication ports are prepared for network management PA-B specification: 1) Output power: 240W (PA-240B), 360W (PA-360B), 480W (PA-480B), 600W (PA-600B) 2) Frequency response: 80Hz-15kHz, ±3dB 3) Input: 1V/10k ohms/balanced 4) Stable voltage output: 70V, 100V 5) THD (at 1khz signal): ≤5% 6) S/N: ≥70dB 7) Power supply: AC 220V, 50Hz-60Hz, DC 24V 8) Ac power consumption: 500W (PA-240B), 750W (PA-360B), 1000W (PA-480B), 1200W (PA-600W) 9) N.W.: 20.8kg (PA-240B), 24.9kg (PA-360B), 26.8kg (PA-480B), 27.7kg (PA-600B) 10) G.W.: 23kg (PA-240B), 27kg (PA-360B), 29kg (PA-480B), 30kg (PA-600B) 11) Body dimensions: 482 x 132 x 430mm 12)Outer packing: Carton dimensions: 532 x 238 x 498mm
