TEST: Peavey IPR 1600

 Eager readers of my power amp test reports may have already noticed that the company name "Peavey" is used quite often, especially in the introduction to my articles. One of the reasons for this is that my "performance-related formative phase" in terms of power amplifier technology was directly linked to the American company. As with all up-and-coming young artists, I had the most technical problems in the rehearsal room in amplifying the vocal area, which was repeatedly expressed in whistling microphones and clippings from the poor power mixers of the time.

The measure of all things were the first consoles of the Mackie generation and as a reinforcement element, Peavey CS 400 or CS 800, their character a sure guarantee for a performance without interruption and, in their first generation, for the nearness of the first herniated disc with incorrect lifting technique. Peavey was making trademarks in final stage technique at the same rate as a male raises his leg on a morning walk. If you had Peavey, you had no problems!

Those times are long gone. Thanks to Class D technology and significantly thinner sheet steel, power packs weighing a hundredweight have outgrown the weight classes of a Fischer kit and the manufacturing facilities of the national pride of the Americans have long provided jobs in the low-wage country of China. The number of well represented American trademarks and the bold print "Designed And Engineered In The USA", which is intended to distract from the "Made In China", have remained. Let's see what American values could be saved to the Asian area.




construction

The Peavey IPR 1600 comes in the standard height of 2 height units and the dimensions: 89 mm x 483 mm x 282 mm and with a weight of only 3.23 kilograms it is about to take the top spot in the field of lightweight construction. It should be clear to everyone that this weight cannot be combined with a solid construction. The sheets of the IPR 1600 are designed in a very thin and at the same time not very torsion-resistant variant. To what extent twisting of a housing is ever an issue is another question, but as I said, the design cannot be considered massive. There is also a little play between the individual sheet metal elements, but this does not detract from a general clean processing level.

In terms of performance, the power amplifier is in the midfield of current Class D power amplifiers, i.e. 2x 530W / 4Ohm, 2x 800W / 2Ohm and 2x 300W / 8Ohm. In terms of input, XLR / jack combo sockets are available, which allow a daisy chain arrangement via a thru output. 2 Speakon are available as outputs. All plugs function properly, but have a rather cheap plastic finish. Although all connectors are screwed to the housing for strain relief, they are otherwise soldered directly to the circuit board. There are no strong pole shoes or even peer-to-peer soldering here.

The power amplifier provides three operating modes with the designations "Hi Pass", "Full Range" and "Subwoofer", whereby an integrated 100Hz crossover, switchable per channel, specifies the crossover frequency. The product is cooled by a variable-speed fan on the back of the housing. Among other things, the patented DDT speaker circuit is at work as a protective circuit. On the front, 2 level controls, combined with 5 LEDs, which provide information about on/off, the signal present, the protection circuit, temperature and direct current, set the tone.

If you open the case, you quickly realize why the power amp is so extremely light, the case is about 70 percent filled with air. I can't quite understand why Peavey doesn't use a smaller format, such as the half rack format, with such an excess of unused space. I'm thinking of an attractive handbag-sized format here, but the marketing department must have had other things in mind.

Even if the additional carrying straps on the front of the case make transport easier, they make placement in the rack a little more difficult. The attached screwdriver will scrape off the paint on the carrying straps with the first twist, that's for sure.


Practice

Anyone who still believes that what is basically just a workhorse like a power amp is all about the inner values will be taught a lesson by the IPR 1600 at the latest. Similar to how some guitar amplifier manufacturers have switched to the principle of optical puppet theater by illuminating the internal components with LEDs or fluorescent tubes, Peavey is also trying to breathe a "hip" character into his product by means of visual "pimping".

When activated, the power amplifier lights up light blue from the inside, which in terms of color does not even appear unattractive. Whether you appreciate such little color games or not is up to personal taste, but what seems completely out of place in my opinion is the standby mode of the internal lamps. Even if the product is still switched off, the standby lighting is already drawing power from the network. The product can therefore only be completely deactivated by pulling out the mains plug or a switchable power strip. At a time when consumer electronics are getting more and more snubs for missing "real" mains switches, I think it's more than stupid to transport this idiotic bad habit to the more or less professional work area. Technically, there were no complaints during the test.


Conclusion

In my opinion, the Peavey IPR 1600 is a product that does its job properly at first glance, but gambles away a lot in detail, or would make a much better impression in a different conception. The fact that almost 70 percent of the interior, similar to that of a CD player, consists of air, suggests that the product can be used as a miniature amplifier, for example in a 9.5 cm half-rack format or even smaller as a stand-alone solution for the briefcase would be better received than sticking to the traditional 19-inch format.

The sheet metal that is not very stiff against deformation, the "plastic-heavy" approach to the construction and the primary design in favor of optical presentation at the expense of professional design will, in my opinion, not make the IPR 1600 a permanent guest in demanding road use. The extremely low weight undoubtedly invites frequent transport, but the construction will definitely be kept in the semi-professional area, or for the clientele "Hey, my power amplifier has 1600 watts and flashes really cool" it will fulfill its function. No offense…
