When it comes to selecting amplifiers for an actively separated sound-system, there are two different philosophies we would like to present here. Both versions have their own advantages and disadvantages so that it is necessary to take a closer look at the requirements for every use and how to find a good economic and technically sound solution.

We call these two philosophies „Stereo-Setup“ and „Mono-Setup“, because in the stereo-setup, the individual signal paths (hi, mid, bass) of the left and right loudspeaker are amplified by one amplifier each. For the mono-setup, each loudspeaker side has its own amplifier, sometimes even its own system controller. The mono-setup is especially suitable for sound-systems not always being operated in the same configuration, e. g. Line-Arrays with more or less loudspeakers depending on the depth and general size of the audience area. Furthermore, mono-setups can also be operated individually as smaller systems in stereo-setup. The stereo-setup is suitable for permanent installations and for systems with always almost the same configuration. Read more »

Sound pressure meets design

The name says it all: The PSSO Prime System is a professional PA system meeting the demands of contemporary club culture. What makes it so unique is the mixture between high quality technical components – all premium drivers come from the French company CELTO Acoustique – and an extravagant design.

If there was a league for speaker cables, our new representatives would definitely be part of it. With Neutrik as team mate and German manufacturing skills, the enormous high quality of our cable team shines through.

The 2 pole speakon cables from PSSO have been developed to serve the demanding and professional engineer. It was our goal, to produce a highly reliable cable which is rugged enough for the road and which overcomes a vast number of plugging procedures uncomplainingly – everything without being too expensive. In collaboration with Neutrik we have achieved this goal.

Neutrik supplies the very stable Speakon NL2FC cable plugs, the cables are made in Germany. Up to now we offer three cables with different lengths, 5 m, 10 m and 15 m.
With our PSSO Speakon cables we have accommodated a new product family which is perfectly suited for our PSSO audio products. And one thing is sure, it won’t be the last family to join our cable assortment.

• Connector A: Neutrik Speakon NL2FC plug
• Connector B: Neutrik Speakon NL2FC plug
• Cable cross-section: 2.5 mm²
• Cable length: 5 m, 10 m, 15 m
  
• Cable diameter: 7 mm
• Weight: 0.5 kg
• Cable construction 140 x 0.15

The human ear is mainly adapted to the frequency range where speech is transmitted. Frequencies below this frequency range are less noted although the same physical level is present. In practice, this effect requires higher bass power e. g. by more powerful subwoofers, more subs or a mixture of both. As speakers generally have a low efficiency comparable to a halogen lamp, manufacturers try to achieve the highest efficiency by optimized housing shapes. But not every housing shape is suitable for every event location and audience. The following article should help to find the suitable subwoofer type.

1. Introduction

The loudspeaker celebrates its 150th anniversary based on the invention of the telephone by Philipp Reis in the year 1861. Already in the year 1878, the electro-dynamic loudspeaker was patented. This kind of loudspeaker is still built into most speaker-systems today.

If such a loudspeaker is operated without housing, an acoustic short-circuit is produced because the sound waves produced by both membrane sides are eliminated by each other. The volume is clearly reduced, especially the lower frequencies. A pragmatic use is not possible like this so that diverse types of loudspeaker housings for different applications were developed.

The preset we provide for the PSSO Compact Line Array is based on the last years’ experience and should help to find the perfect settings for your application.

For this setup, we use the following components:

8x PSSO CLA-228 at PSSO HP-1400 (Hi) and HP-2400 (Mid)

2x PSSO CLA-115 at PSSO HP-2400

4x PSSO CLA-118 at PSSO HP-3200

2x PSSO SUB-2180 at PSSO HP-3200

The gains of all power amplifiers are set to maximum.
