Power on all four channels

The Quadro 500 DSP is an amplifier from Thomann's own brand the t.amp, and it's outstanding in more ways than one. The amp offers four inputs that aren't just independently controllable, but can also be routed to four outputs in any order. The Quadro also offers whole host of settings and options, accessible both on the unit itself and via a connected PC. A Class D amplifier, the t.amp Quadro 500 DSP has solid technical specs, with high amplifier efficiency and low heat generation. Still, users should make sure they've got enough space to install it simply due to the amp's dimensions; it's a standard 1U rack amp, but at 460mm deep larger than many amps.

Professional EQ, PC control

Despite the pared back appearance of the 46cm long amp's housing, the menu is impressively detailed. On the front there's a rotary control for navigating the display and a USB-B port for connecting the amp to a computer. That's pretty much it though, apart from the on/off switch – no mute buttons for the outputs, for instance. On the back, there are four XLR inputs, four lockable Speaker Twist outs (each with 500W output at 4 ohms), and a practical resettable fuse. But now on to the menu: It can be operated particularly comfortably on a Windows device, where the outputs can be freely assigned and muted; each channel also offers a fully parametric eight-band EQ with the phase rotation and bypass functions, a line delay, high-pass and low-pass filters with selectable filter type, a compressor, and a gate. Any combination of these settings can also be saved as a preset.

For more than two speakers

The t.amp Quadro 500 DSP really comes into its own when more than two speakers need to be connected. This could be, for example, a four-point PA system where the guests are seated in the centre. In long rooms, or even churches, a delay line can be connected to the two additional outputs in addition to a classic front PA, especially since the Quadro comes with a delay function as standard. Operators of small clubs and venues can hook up a set of monitors, in addition to the FOH speakers. The fact that the built-in fuse can be reset is especially useful for live operation, and for schools or event spaces where the equipment has been professionally installed by a technician, the amp can be secured with a PIN to prevent unwanted changes.

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.

Powerful control centre

Before using the amplifier with a PC for the first time, the amp's driver needs to be downloaded from the product page. To connect the amplifier to the computer, use a standard USB cable and make sure that the amplifier's power supply connection is securely plugged in. The EV ZLX 12 passive 12" speakers, for instance, make ideal front speakers. If the plan is to connect stage monitors to the two other outputs, we recommend the LD Systems Stinger 8 G3 or the FBT J8 J-Series. Suitable speaker cables are available in various lengths: For example, the pro snake TPL 10 LL is is a professional-grade 10m cable.

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.

Perfect amp for creating an 8-way monitor mix!

heyimdan-dan 09.06.2021

I bought two Quadro 500 DSP power amps to ditch four very heavy amplifiers that were taking up 8U of rack space. I was unsure about how well these amps would perform, but after getting them hooked up to my wedges (250w 8ohm speakers) there was little doubt that I'd retain all the power I had before and make a lighter rack case.

The main attraction meant I could have a single rack that connected the two amps directly to my Midas DL32 stage box, with all the speaker DSP in there too, making for a very compact and quick gig set up.

The interface is great and very straight forward with lots of features I'll likely never need, but it's great to know it's there. From within the menu you can pair up XLR inputs to XLR channels. For example, Input A will send the source to Output A and B. Sadly you can't currently send Input A to say Outputs ABC&D. That would be very handy for particular circumstances, especially since there aren't any XLR thru's to link channels. But some XLR splitter leads can navigate that issue. (EDIT: I have since worked out how to take the input from channel A and use it to drive all four speaker outputs)

Considering buying more to run my FOH high frequency drivers. (EDIT: I bought two more of these amps to run the HF drivers in my 16 box line array, with 8 boxes per side. Each HF driver is 16 ohms, and there are two in each cabinet. I use one speaker output channel to run 4 HF drivers, and with the volume level at -12db, so the amp is only outputting at about 60-70 watts and this is more than enough. The clarity is excellent and I can’t fault it.)

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.
