PL+S 2019: Powersoft to debut audio innovations

The manufacturer is set to showcase a new amplifier, OEM components, and an update for its Snapshot Selector app

Powersoft will return to Messe Frankfurt for this year’s Prolight + Sound with a variety of audio solutions, including the brand new X4L amplifier; the LOTO DSP 1-2 in / 4 out Advanced DSP board; the DSP-Lite ETH 1-2 in / 3 out DSP interface; and an update for its Snapshot Selector mobile app.

The company’s stand, which can be found in Hall 8.0 (G40), will also feature some of its more established products, including the T Series amplifier platform.


As the latest addition to Powersoft’s range of amplifiers, the X4L has been created to drive modern high SPL woofers that require high voltage, in order to deliver their full potential. The product is designed to provide up to 300 V (peak) to the loudspeakers.

“In our research activity, and during interactions with producers of loudspeaker components, it has become clear to us that this is the next logical step for the powering of these solutions,” said Klas Dalbjörn, Powersoft product manager.

The product is able to deliver the same or more power per loudspeaker while driving more cabinets in parallel when compared to other amplifiers, which can save users both money and truck space on portable applications. It also has 5 output connectors to allow connection without adapters for many expected configurations, such as channels 1 and 2 driving a cardioid sub solution, while channels 3 and 4 drive some 2-way front fill in parallel.

“In such a configuration,” commented Dalbjörn, “the X4L is capable of giving one dB more burst power to the two most power demanding channels, which in this case would be the sub channels.”

OEM Solutions by Powersoft

LOTO is a 1-2 in / 4 out processing board designed to provide advanced DSP functions to any powered product. It comes in two different types: Basic and Advanced, both featuring the same characteristics of the high-end X-Series platform, LOTO delivers parametric raised cosine filters, custom FIR and IIR equalisers, as well as TruePower, RMS and Peak limiters, Active DampingControl, and Live Impedance all completely supported and managed via ArmoníaPlus.

LOTO Advanced further increases routing options by adding 2xAES3 digital input streams through XLR connectors, and the support of Dante digital audio networking architecture, with two inputs and two outputs.

Compatible with Digimod PFC2- PFC4, IpalMod, Litemod family, and Minimod4 amp modules, LOTO is ideal for any application with high processing and digital audio networking requirements.

“With the introduction of DSP LOTO platform,” said Powersoft’s Giacomo Previ, global sales manager – OEM Solutions, “Powersoft is now able to offer to OEM manufacturers the same advanced processing capabilities of its top-of-the-range rack amplifier series. This will enable to create a very powerful and flexible Powersoft ecosystem, easily controlled via ArmoníaPlus suite”.

DSP-Lite ETH is a 1-2 in 3 out processing board designed for LiteMod Series, MiniMod4, and DigiMod PFC2/PFC4 amp modules, integrating a compact interface panel compatible with mono-in / link-out or stereo-in configurations.

The built-in Ethernet port allows to access DSP-Lite ETH processing capabilities directly from the PC running ArmoníaPlus software, to easily program and store up to four presets that can be selected by the end user. It is compatible with Powersoft Integration Kit platform.

Snapshot Selector

As well as the new hardware offerings, Powersoft will also use PL+S to launch an update of its Snapshot Selector app, which was originally released at the end of 2017. The free and easy-to-use program is now also available for iOS devices, and it allows users of Powersoft’s X Series, Ottocanali DSP+D Series and T Series power amplifiers to instantaneously recall a full set of saved settings by connecting their phone to the front of their amplifier with a USB cable.

T Series

Following its successful launch at NAMM, another of Powersoft’s latest touring products – the T Series – will be presented to PL+S visitors. The T Series consists of both 2- and 4-channel models available in 3,000 W and 6,000 W versions, supporting channel powers from 750 W to 3,000 W in a single rack unit. All models can deliver the same high peak voltage and can drive single 8/16 ohm cabinets at full SPL, making the T Series a cost-effective solution for small systems without boxes in parallel. The high voltage can also be used for power-sharing between channels for applications such as bi-amped loudspeakers or subwoofers with passive tops.

In addition to analogue inputs, the T Series also includes AES3 and Dante by Audinate inputs, which are optimised for daisy-chained distribution of networked audio to multiple amplifiers with no need for external switches or splitters. Each model features group controllable advanced EQ to let users equalise multiple amplifiers in a chain, as well as a robust preset library with FIR processing.
