Camco amplifiers made smarter with new UCA DSP

One thing the Frankfurt Pro Light and Sound show had in ever increasing quantities was amplifiers. Even at the top end of the amplifier market, there are only microscopically small collections of products that differ much from the bulk of Asian assembled products, as far as technology is concerned. Engineering and build quality is another matter of course. Even among the top echelon, there are only a couple of lightweight, high-power amps that are going to stand the test of (sonic) time. The Camco Vortex and Tecton series are at the top of the tech tree, so what could possibly make them better?

OK then, get out your Tech Dictionary for this new Camco product… There's nothing worse than spending a pile of money on a hot new killer product to have it suddenly obsolete before your third lease payment. That will never happen to a Camco owner. Like French company Nexo, German engineering is based on a well researched, long lasting platform that can be added to and improved with upgradeable add-ons rather than dumping the whole investment for a new one.

Let's bolt on a UCA Network Signal Processor

Enter the new Camco DSP-Module that allows either Tecton or Vortex amplifiers to become a U niversal C ontroller A mp. Full parametric EQs, delays, llR-filters, X-over and limiters are naturally selected and controlled via the multithreading Camco WinCai remote control application. That was a mouthful but there's more.

The UCA module is fully integrated with the amplifier and data exchange is achieved via internal interfaces. In addition to this freely programmable controller software, and a real first in amplifier design and construction, you can download “parameter sets” into the UCA from an accredited measuring system. If that wasn't enough tech-head spiel, try this on for size. Ever met “Hugo?”

The esteemed team of Dr. Anselm Goertz and Dr. Swen Müller designed in conjunction with their activities at the institute for technical acoustics in Aachen , the measuring system, which supplies amongst others the established measurement values for the Production Partner magazine test reports. (Production partner is the consumer Choice Magazine for engineers in Germany , and a very respected publication among the international engineering community). Based on these measuring system values you can also have a D igital S ignal P rocessing system especially designed for your application or speaker system (HUGO) .

What does it all mean?

Well it means you can have across your system:

1. Foresight limiter with "controlled overshoot" for utilization of the impulse reserves of the amplifier with regards to the loudspeaker's thermal equivalent circuit diagram

2. High-precision FIR-filtering via the MF measuring system

3. A bunch of other stuff the Filter Editor doesn't understand but it looks great on a laptop

Below is the package as you get it to install into your Camco amplifiers:
