Hi! Using linux + ladspa should make it easy building signal processors like the DBX DriveRack or similar devices… Unfortunately, I don't know professional grade audio devices offering 2 balanced (XLR) input and >4 (preferable 6) balanced (XLR) output ports. Does anyone know? Greets! Mitsch

I set up a triamp system with zita-lrx years ago. Still using it. On Mon, Apr 20, 2020, 4:32 PM Michael Jarosch <riotsound(a)riotmusic.de> wrote:

Hi ! Since you don't need XLR for this (Line level balanced inputs/outputs will do) You could go for any good interface with enough in/out i have a few Motu Ultralite AVB interfaces that has 6 balanced line ins and 6 balanced line outs + balanced main and two High Z Guitar inputs + 2 xlr mic preamps. Balanced TRS to XLR short adapters would work for you but I can not recommend Motu Ultralite AVB for linux since the new model is not compatible with older more linux friendly firmware.. You could hower do the same with any decent stable linux friendly interface. AVLinux has a great 3rd party maintained PDF with supported interfaces that would work on any linux. http://bandshed.net/pdf/LinuxFullySupportedDevice9t2.pdf Focusrite Scarlett 18i20 maybe ? Behringer if you dare..I would Den mån 20 apr. 2020 kl 22:32 skrev Michael Jarosch <riotsound(a)riotmusic.de

Another option: get a small mixer that has XLR, connect your XLR devices to that mixer, then run output from the mixer to your existing audio interface. That's how I handle XLR and electric guitar inputs with my little Behringer UCA-202. ;) On 4/20/20 10:58 AM, Anders Hellquist wrote:

I used to use an Echo AudioFire 12 with zita-lrx setup, but haven't had any li k with firewire with kernels for the last couple years. Since I'm using the tri-amp system as a listening system, i.e. not recording/studio, I have switched to the 6 channels on the onboard sound. But, have also successfully hooked it up with usb mixers as well. On Mon, Apr 20, 2020, 11:22 PM david <gnome(a)hawaii.rr.com> wrote:

... I'd second the Scarlett 18i20, there apparently are drivers now, even for the latest generation.

I guess, I'd be more precise in my needs to prevent starting a flame war about the best sound device on linux… :) I'm searching for a more DIYish sollution. It needn't to be in a case. Anyone knows the HiFiBerry DAC+ PRO XLR <https://www.hifiberry.com/shop/boards/hifiberry-dac-pro-xlr/>? Unfortunately, there is no input and as far as I know you can't cascade it to a 4/6-output device. But something like that would keep the price low. Of course, using Linux and not being dependent by a company is a value for itself. But it doesn't make sense to me using a sound device that alone exceeds the price of a brand new DBX DriveRack. A LADSPA virtual crossover network doesn't need much performance. I like the idea giving obsolete audio devices and PC hardware a new life. Compactness and quietness, on the other hand, does matter. Combining a Raspberry Pi 4 with an Echo Audiofire 12 would be a killer. Unfortunately, there's no GPIO2Firewire… By the way: In the home setup for my music production PC, I'm using a RME HDSP 9652 for a 4.1 setup. The satellites have no passive crossover, so I need 9 outputs and 9 amps. Carla's my virtual crossover network, I'm using Pere Ràfols Soler's EQ4Q for filtering. I'm thinking of a "speaker controller" for places where I work that want to improve their sound infrastructure. Being cheap but powerful / high quality is the challenging way to go, there… :) Greets!
