Two final questions (I hope). 1) If I used an iPhone as a digital source could I use it also to control the volume on the 8240s in stand alone (manual setup)? I tried this but it seems that when I have the iPhone turned all the way down it mutes the volume but the instant I bring up the volume slider (on the phone) the level immediately goes too high (even if I have 42db of attenuation dialled in on the dip switches of the speaker.
2) Alternately, could I use the wireless volume control with the new GLM 2.0 interface to control the volume of 8240s in standalone (without a computer)?
iPhone can only output analogue signal, not digital.
iPhone can only output analogue signal, not digital.Actually the iPhone (or iPad) can transmit digital audio over a wireless network. I wirelessly transmit from my iPhone to an Apple TV or Airport. I then take the optical out, convert it to AES/EBU and feed into the Genelecs.
I must have set something incorrectly last time because I tried again and was able to control the volume from my iPhone in standalone mode. The question remains... Would I get better sound quality using the wireless volume control with the GLM interface (in stand alone mode of course) or... is digital volume control pretty much done the same way regardless of device?
You would have to test it for yourself to be sure. Technically it's better to attenuate the signal after the DSP and signal conversions.
Hi,If it's digital signal, then the red light indicates that the digital level of the signal is very close to 0 dBFS.
Hi,If it's digital signal, then the red light indicates that the digital level of the signal is very close to 0 dBFS.The source signal is digital. I'm just surprised and confused that the Genelecs are showing digital clipping when I'm using commercial uncompressed CDs (WAV) files. That so that would mean that the iPhone is applying gain to the original signal. That doesn't seem right so I'm wondering if something else is going on. Also, and more importantly...
If I use a pair of 8240s in combination with a 7260 (properly calibrated with the GLM 2.0 interface) what are the ramifications of using them at the correct distance but in a room much bigger than they were designed for (roughy 400 cubic meters)? Am I just going to limit their ability to achieve realistic SPL's?
