Unica 4T

4-Channel Amplifier Platform for Touring Applications

The touring version of UnicaTM is

a compact, 1RU amplifier platform

developed for rental companies and

live shows. This 4-channel version

features a 20.8kW total power

model, keeping true the power

density of the UnicaTM platform.

The output channels can deliver

up to 7500W @ 2.7 Ω for the

20K4T model when asymmetrically

loaded. The power supply allows

worldwide operation (100-

240VAC), and it is equipped with

the latest generation of single-

stage power factor correction

(PFC). The proprietary Smart Rails

Management (SRM) allows the

supply rails to adapt in real-time

to the required output voltage to

maximize efficiency and reduce idle

losses.

UnicaTM platform features

Powersoft’s next-generation DSP

for state-of-the-art processing and

pristine audio performance. The

three 1Gb Ethernet ports, along

with the native DanteTM and AES67

support, allow for different network

topologies, including daisy-chain

and DanteTM redundant.

Studio-grade Galvanically

Insulated Analog Inputs for

each channel provide immunity

to noise coupling, excellent

common mode rejection ratio

(>90dB up to 1KHz), and abuse

tolerance on the analog inputs.

The front panel display allows

quick access to the amplifier

operating status, including

headroom, input levels, and more

information for local monitoring.

Custom Ruggedized Phoenix

Connectors Housings, designed for

heavy-duty applications, provide

strain relief and quick locking/

unlocking functionality (pat.

pending).

Lastly, UnicaTM Series amplifiers

natively support cloud connectivity

for remote monitoring and control

from any device anywhere in the

world via the Powersoft Cloud.
