A top seller for discerning users
The t.amp Proline 3000 has long been one of Thomann's top-selling power amplifiers for PA applications. This should come as no surprise, since it meets professional demands in several respects. The Proline 3000 comes in a 19"/3U rack format, and the two-channel amplifier unit processes audio from 20Hz to 20kHz. Thanks to its two powerful transformers, it provides 2x1700W into two ohms (i.e. offers two-ohm stability) and is thus suitable for sound reinforcement applications with an audience of just over 350 people. The power amp offers numerous protection circuits, which include a built-in limiter and a soft-start function, while XLR and jack inputs as well as speaker twist outputs provide professional connection options.

User-friendly and flexible
The amplifier unit of the t.amp Proline 3000 is designed as a Class AB amp and can accordingly deliver high efficiency with minimal distortion. One advantage of this amplifier unit is that it offers a choice of three different modes: Stereo, parallel, and bridged. In stereo mode, the power amp's two channels operate independently, while in parallel mode, two speakers can be driven using the first channel of the amp. Bridged mode in turn allows the signal coming from the first channel to be amplified at twice the power. The Proline 3000 is also user-friendly thanks to its LED indicators, which help the user to operate it safely: A signal LED indicates whether an input signal is present, for example, while a clipping LED indicates that an overload is present (and the integrated limiter has been activated) or a short-circuit has occurred. Further LEDs in turn indicate whether the amplifier is in an unstable condition or is overheating, as well as providing information about the active operating mode. In addition, a ground lift switch is provided to help eliminate ground loops.

For DJs, bands, organisers, and rental companies
Thanks to its professional design and features, a wide range of users will find the answer to their specific requirements in the t.amp Proline 3000. For example, it is suitable for event organisers looking for an affordable but high-performance power amplifier for use in a fixed installation. Rental companies in turn can add this reliable power amplifier to their portfolio at an affordable purchase price and thus provide a robust and easy-to-use rental amp. And both DJs and bands can use the Proline 3000 to upgrade their PA systems to a new level - after all, up-and-coming artists who have conquered the bar and youth centre scene and want to move on to small clubs will need a big enough PA to do so. More generally, however, anyone who can do without DSP effects or an integrated crossover can definitely take a closer look at the t.amp Proline 3000.

About the t.amp
the t.amp is one of the many in-house brands belonging to Musikhaus Thomann, and since 1998 has offered power amplifiers, complete passive PA sets, keyboard amplifiers, and connection systems. The brand’s entire product range delivers an impressive combination of quality and reliability at attractive prices, and users can find a convincing and affordable solution for every application: From youth clubs and sports halls through to congress centres and much more.
For fixed installations and touring
Bands can use the t.amp Proline 3000 for larger live performances as part of their touring setup, and event organisers can combine two of them for outdoor sound reinforcement at street festivals and open air events. Concerts and small festivals with 300 to 400 guests can be run without fear of the sound going out with this power amplifier's help, but it will also cut a fine figure as part of a fixed installation in a club. It doesn't matter here whether or not the Proline 3000 is used in rooms that are properly ventilated or cooled, as two temperature-controlled fans are also on board to cool the amplifier down when needed. The amplifier's rack compatibility will be a major advantage for all of these applications, but those who plan to use it as part of a mobile rack should take note of the fact that it tips the scales at an impressive 37kg.

In the spotlight: Two-ohm stability and bridged mode
The signal output from a power amplifier can hit speakers with different impedance levels. For the operation of loudspeakers with irregular impedance characteristics, a power amplifier should therefore have a suitable "load stability" in order to allow performance shortcomings such as weak dynamics, a muddy low-end response, and unwanted distortion, to be avoided when the corresponding speakers are connected. A solution can be provided by power amplifiers that have a "bridged" mode, which combines the outputs of two channels. Because they are then phase-inverted, the existing output voltage is twice as high for the connected speakers, meaning that the resistance encountered by the output signal can be twice as high without compromising the load stability. As a result a power amplifier that has "two-ohm stability" can have four-ohm stability in bridged mode, allowing it to optimally drive speakers with an impedance of four ohms.
