Detailed Description UNICA 4T
UNICA 4T is the 4-channel touring model in the Powersoft UNICA T family. The manufacturer identifies this configuration as 4T 20K4, with a commercial total rating of 20800 W at 2.7 Ω under full symmetrical loading. The 1U platform combines high output, network audio and loudspeaker processing for demanding live sound systems.
The amplifier provides 4 galvanically isolated analog inputs and eight Dante / AES67 network-audio channels. Three Gigabit Ethernet ports support Switched and Split-Redundant operation. Rugged connector shells adapt the Phoenix input and output connections for touring use, while ArmoníaPlus and Powersoft cloud services support system configuration, supervision and remote monitoring.
Power Sharing allows the output capacity to follow unequal loudspeaker loads, within the limits published for each impedance. The onboard DSP combines FIR / IIR filtering, time alignment, Dynamic EQ and complementary RMS, peak and TruePower limiters. Active DampingControl addresses cable losses, while pilot-tone and impedance monitoring help supervise the connected loudspeaker system.
The universal power supply includes PFC, Smart Rails Management and surge protection. Eco and standby modes reduce consumption when full output is unnecessary. A separate PoE backup can maintain the control CPU for fast recovery; it does not supply loudspeaker output power. Applications identified by Powersoft include touring, arenas, concert halls, stadiums, open-air events and mission-critical multi-zone venues.
