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 light2) Balanced input expands signal transmission distance and improves its anti-jamming ability3) The user can force it to switch to the signal input priority end to carry out emergent broadcast by short circuit or DC24V forced switch4) Gain input adjusting freely is available for the user5) When AC is in a fault, the equipment will be made to go on running by backup power supplying system6) Internally fixed with scheduled system for starting the machine or turning it off.7) Digital communication ports are prepared for network managementPA-B specification:1) Output power: 240W (PA-240B), 360W (PA-360B), 480W (PA-480B), 600W (PA-600B)2) Frequency response: 80Hz-15kHz, ±3dB3) Input: 1V/10k ohms/balanced4) Stable voltage output: 70V, 100V5) THD (at 1khz signal): ≤5%6) S/N: ≥70dB7) Power supply: AC 220V, 50Hz-60Hz, DC 24V8) 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 430mmOuter packing:Carton dimensions: 532 x 238 x 498mmA huge 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 light2) Balanced input expands signal transmission distance and improves its anti-jamming ability3) 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. And it is designed with isochronous control ports over 3-line forced switching4) Gain input adjusting freely is available by the user5) Starting the equipment by short circuit is available6) High efficiency in transformation
WI-202 window interphone features:1) Completely automatic duplex talk back2) The user can separately adjust the sensitivity of the mainframe and extension3) It is sonorous and clear with low backflow4
CCA-15P/3 classroom amplifier feature:The classroom broadcast system outputs at 8 ohms by a 15W power amplifier and inputs by 1-channel MIC and 3-channel AUX with separate adjusting the volume of each
