DSP on 8200: how it works?

Padawan Posts: 33 Join Date: 7/19/13 Recent Posts
Dear all

i'm interested to buy a couple of 8260a. I will have an htpc with a RME HDSPe AIO digital interface on board. I'm not interested to buy GLM or use it in the future. So my questions are:
1)Is it possible to connect to my RME directly to 8260a without GLM and exclude the DSP?
2)Is it possible to control the volume using for example Jriver (it has a good digital volume control on board) or other PC software?
Thank you to all of you.

GLM (Genelec Loudspeaker Manager) is a package which consists out of PC/Mac control software, USB interface and measurement microphone. It is needed if you want to take full advantage of all the features a DSP speaker can offer, such as fully automated AutoCal room calibration procedure. It is possible to use the speaker without the GLM but then you are missing all the advanced DSP features. If you really want to do this, I have to ask; why?

GLM is the only way to control the volume internally, but of course if you vary the level of the input signal, the output signal (=SPL of the speaker) will follow. With analogue signals this is trivial, but I am not sure if RME HDSPe AIO allows its digital output level to be controlled through 3rd party software. It is possible through its own HDSP mixer though.
