the t.amp TSA 4-700

I bought one of these in one of the PA packages Thomann do and was very impressed with it. I play in a heavy rock band and pair this with Behringer Eurolive speakers using two channels for the mains and two for the fold back.
We've played some quite large venues and this has given us plenty of headroom. We have two guitars, a bass, three vocals and drums going through it and it handles the sound with perfect clarity. The bass response is superb and yet never detracts from the rest of the range. Even the bass drum doesn't cause any issues with the sound.
I run it at full volume on all channels with the volume levels being set by the desk. I have never run up to clipping level but have been close and so far there has been no distortion just lots of volume!
I like the fact that each channel has both male and female XLR sockets and the only downside is that it is very heavy.
The four amps can be bridged into two very powerful ones if required but I can't imagine ever needing that sort of power in the venues that we play and I've never had the speakers to take it so I've not tried that mode yet.
All in all I can wholeheartedly recommend this amplifier, it has bags of power and a great sound and feels like a quality product in every respect. In fact I liked it so much that this review is for my second one! Our band is so reliant on it that I bought another one just in case the worst should happen on stage and I can just swap the leads onto the spare but in reality I very much doubt that the original will fail. Not for a good while anyway.

Pirkau ji taupydamas pinigus, bet pasirode visai smagus daikciukas. Kol kas i 2 kanalus esu pajunges po JBL JRX 212 M per krosoveri viduriams ir aukstiems dazniams. Galingumas puikiai atitinka koloneles. nesigirdi jokiu iskraipymu. Prie kitu 2 kanalu pajungiau po monitoriu. Subas su savo stoprintuvu. Ateity planuoju isigyti pasyvu suba ir pajungti ji prie dar 1 kanalo, o jei neuzteks galios, tai sujungti juos i 1.
Garso kokybe labai patenkintas. Tiesa, atsukus 2/3 garso, jau girdisi svypstimas, bet tokiu rezimu ir siaip nepatartina dirbti, todel tai labai neaktualu. Kam reikia tylaus galingo stiprinimo, patariu rinktis didesne galia.
Tokia sistema, teisingai parinkus krosoverio dazni, labai graziai skamba.
Kam nereikia didziuoles galios, rekomenduoji si stprintuva.

I use this amp to amplify a pair of 12"+1,5" speakers (active crossover, so 2 channels for high, 2 channels for mid). Main use : small parties and home cinema/music.

Power is more than enough for my use, price/Watt given the 4 channels is really good and built quality is high. The amp is lightweight. I have not tried it for sub, so cannot comment, but for medium/high I am really satisified with the job done. Input sensititivity is within pro range, which is good because I use a pro sound card as active crossover.

Connectivity/bridging options are flexible and efficient. The fan noise is low when little power is drawn, so acceptable for home use.

Very little downside : high frequency hiss is audible when no music is played, but there is no problem at all when music is played.

Overall a light, powerful and good value 4 channels amp. Delivery etc = perfect job from Thomann!

As a sound engineer these are a dream!

Ive used them to drive 4 stage monitors, 4 tops, 4 subs, and even 2 subs and 2 tops!, The great thing is that this amp is so versitile!
Its lighter than most other amps I own but it really packs a punch.
Visual LED display with very smooth volume controls on the front plus front and rear vents for excellent cooling. The nice paint black finish makes the unit look really smart so excellent for corporate jobs!.

I`d highly recomend this amp for all audio applications. Ive also used one on an install over 3 years ago and its still going strong being used 7 days a week.!

Got two of these amps on Jan 2023. With no audio input and knobs turned down there was a clear hiss on both of them (I guess it's normal based on price / quality) but one of them had a strong electrical interference noise. Probably a construction issue and bad quality control.

After i sent the faulty amp back. Thomann sent me a new one that had exactly the same problem. I was informed that their technicians didn't found any problem with the unit. Luckily i had the other one working fine and could prove my point. I had to send the replacement back again.

After 3 months of use the other one failed during a dj set. 2 of the channels stopped working.

After 4 months I still don't have 2 working amps.

I've bought many T-Amps in the past and have always been happy with them. This one is no exception. I purchased this alongside the Behringer NX4-6000 which is similarly priced. The T-Amp felt much more musical and had tighter bass than the Berry which always felt a bit flat with the music. I play full range music (DJ) so if you needed something a bit more soft maybe the Berry would be the way to go.
The T-Amp also had a bit more power but that may just be down to the input gains which leads to why it only has four stars on sound. If you use high sensitivity compression drivers you will get hiss so this is not suitable for very quiet applications.
For a budget 4 channel amp you can't go wrong!

I have used these amps for a number of years and have just invested in 3 more. For the price these amps give ultimate versatility over the systems in which your powering.
With just 2u of amp rack space you can power a very small front of house or 4 monitor mixes with ease. They have also been extremely robust without a single failure in the 6 units that i have previously bought so this demonstrates the quality of the build as these are used day in day out for rental purposes. They have even been stable running at 2 ohm in a pinch running extreme sub duties which is unheard of for a product of this price. The only slight negative with this product that it can seem a little noisy on the outputs when used in low level applications, however this isn't noticeable at louder volumes.
All in all a great product for the price and to get anything better you would have to spend 3 times as much money.
