Pi4-6K D

Pi is a multipurpose series of power amps for touring and installation applications, based on the legendary QuantaPulse™ switching mode power supply with an innovative class H 3 steps topology.

This series includes a completely renewed PMS™ which incorporates a set of protection systems in power supply and audio modules which works in real time continuously maintaining all variables of the amp within safe working threshold always. So, Pi amps are appropriate machines for the most exigent applications with the best reliability.

Pi amps have been designed with a non-symmetrical class H topology which allows working with very high voltages given incredible headroom and a great punch.

All these characteristics make Pi amplifier an interesting device to work with asymmetric loads to squeeze every last drop of power in each way of the sound system.

Pi series has an extra-large 4.3" display with capacitive touch panel whereby it is possible to control and manage every parameter of the amp and select all System Presets, Uses, User EQ and Snapshots created.

Also a powerful FIR DSP has been implemented in these amps with a software specifically developed for this series.

Standard Pi amp is equipped with DSP (4 Inputs/4 Outputs real time fully programmable through Ethernet, USB or directly from the large frontal touch panel) and industry standard Neutrik® XLR input.

Besides the DSP, this version of Pi amps includes Dante™ Networking, compatible with AES67 and Dante Domain Manager™ (DDM).

Besides the DSP, this version provides standard AES3 (AES/EBU) digital inputs, at any sample rate.
