Wasn't sure, but...!!
Adeler, 20.05.2019
I ordered this amplifier because i have a 2 way system at home.
I was very unsure, but it turned out that the amplifier was very good.

Sound quality is great! Nothing to say about it! It's class D. No coloring of the sound as far as i am concerned

What i was unsure about was the ratings, it dosesn't say much about load/ohm/watt at what THD.
I have measured it to deliver 4x640w @ 4 ohms @ 1% THD so i am quite happy!

Also, i was exited to find out about noise from the fans. I can't hear them, really. There are two temperature controlled 80mm fans placed at an angle inside, pulling air from front and side and pushes it out on right side.

It's easy to use! Both the software and the on board controller works really great to set up, load, save and adjust presets and settings.

I REALLY recommends this amplifier, especialy for home use (Example; home teatre/home cinema, multi way setups and sub arrays)

I don't know if there are any amplifiers that can compare with this one for the price, and maybe even even more expensive amplifiers.

best choice for this price
Oliver Kocsis, 30.01.2019
I use it in a church, to everyone's satisfaction, it was the best choice, I chose because of theintegrated DSP and delay, together with a Behringer xr16 (fixed install, no buttons, no faders= no problem with amateur sound guys). Crystal clear sound, good damping factor, simply and useful one button menu for configuration, all for a very good price. I am also pleased with the customer.

Incredible for the price
domwat, 29.10.2018
4 channels @ 500watts in a 1ru package with built-in DSP, sounded too good to be true.

but boy was I impressed when the unit arrived!

The onboard menu is super easy to use with the jog wheel, with all of the options 1 Submenu away, presets are great too

Sounds clean and I don't doubt its ability to provide 500w @ 4 ohms

unsure of where to source the software for programming, but not sure it's even necessary.

Top Endstufe
DJ Fritz, 28.02.2021
Die t.amp Quadro 500 DSP wirkt sehr wertig und ist entsprechend gut verarbeitet. Angeschafft habe ich mir die Endstufe eigentlich als Back Up, inzwischen überlege ich aber sie regelmäßig einzusetzen. Leider kann man ja zur Zeit nur zu Hause testen aber auch in meinem Kellerraum war ich direkt von der Leistung überzeugt. Die Software ist schnell installiert und selbst erklärend. Als Lautsprecher habe ich 2 Bässe KME VB18 und 2 Seeburg Top´s A3 MK2 an der Endstufe betrieben. Mit zwei 4 poligen Speakon Kabeln kann man Kanal 1 und 2 und 3 und 4 von den Ausgängen 1 bzw. 3 abgreifen. Leider geht die vierpolige Belegung der Kanäle 1 und 3 nicht aus der Bedienungsanleitung hervor. Aber nach Rücksprache mit der Firma Thomann wird diese wohl in nächster Zeit dahingehend nachgebessert. Somit ist ganz einfach mit zwei Kabel für die beiden Lautsprecherpaare zu arbeiten. Da meine verwendeten Lautsprecher alle mit 4 Ohm Impedanz ausgelegt sind ist die Leistungsausbeute sehr gut. Sobald die ersten Einsätze wieder möglich werden, berichte ich direkt mal vom Live Einsatz. Aber die Testläufe zu Hause lassen die Vorfreude schon steigen.
Eine kleine Anmerkung noch zu der Software, schön wäre es wenn man den Limiter (Kompressor dient gleichzeitig als Limiter Ratio auf Limit gestellt) direkt in Volt angezeigt bekommen würde. Außerdem gibt es beim Hochpass keinen BW12, der wird nämlich von Seeburg für die A3 MK2 gefordert. Allerdings gibt es von mir dafür keinen Abzug, da man für den sensationellen Preis schon sehr viel geboten bekommt.
Auch andere Lautsprecherpaare sind mit dieser Leistung denkbar, JBL JRX 218s oder The Box pro Achat 112 Sub arbeiten beide mit 4 Ohm, Top`s würden sicher auch gut mit 8 Ohm Impedanz und dann eben 250 Watt arbeiten wovon es ja sehr viele gibt.
Zu bedenken ist vielleicht noch die große Einbautiefe bei der Wahl eines geeigneten Cases.
Abschließend würde ich die Endstufe als absolut gelungen bezeichnen und vergebe deshalb auch die volle Punktzahl!!!
