OT: Guitar level- Mic or Line?

by Simon Williams

Hello. I often run the PA system for my CU at uni. So far we've been using jack-jack leads to connect guitars to the desk. However, my Dad has recently started using jack-XLR leads at my home church and says that it's much better. After a very long conversation and lots of googling (which incidentally provides no info at all on the subject), I'm now completely confused. Are guitars mic or line or what? The rationale for using jack-XLR leads and connecting to the mic input on the desk is that guitars have mics in them so they are mic level. Apparently the battery unit in the guitar doesn't make it line level, but I'm not convinced. The other thing I don't understand is that if that is the case, why do people use DI boxes? A DI box takes a high impedance (line level - I think) input and converts it to low impedance output (mic level). If the guitar is mic level already then what's the point? Please, could someone shed some light on this because I'm now very confused. Thanks in advance. Simon

Other Uses for Guitar Amplifer Preamp Stage

by Christian Delahousse

Hey Guys, I have a Fender Hot Rod Deluxe guitar amp and noticed there is an preamp out for an effects loops. I was wondering if there were any other uses for this? Would the output on this suitable to bypass the preamp on my audio interface? Would this tube preamp stage be of any benefit? Could I hook up an SM57 to the amp input to be sent to the interface? Thanks

hardware: recording voice and acc. guitar

by schoappied

Hi, I want to be able to record voice and acc. guitar. I like to have it cheap, but good... ;) 1. Which mic do you recommend? 2. Do I need a mixer? If yes, which one is good, or which brand? Do I need digital effects? What are other important things? 3. Do I need a new soundcard? I've now an onboard one and can play guitar with not to much latency or xruns... Thanks in advance, Dirk

Audio within the range of the human voice needs to be crystal-clear. It's not. In alsa-mixer I have to nudge mic-boost 2/3 of the way up to get moderately successful results. When I try to listen to Youtube, the sound is so faint as to be unhearable. The best laptop soundcard that I know of is the Indigo IO PCMCIA, but my computer has one of those newfangled card slots, and so I had to go with a Creative SoundBlaster X-Fi. But wait! The X-Fi isn't supported yet by alsa, although it will be soon. (The beta drivers so far haven't worked for me.) There are bug reports all over Ubuntu about how poorly hda-intel works. They won't be fixed until Intrepid, but maybe you won't buy your computer until then... Does anyone have any sympathy for me? S

old problem: alsa device or resource busy

by Rich E

I know I have seen this hased a few times... but never seen an answer. Occasionally something grabs the ALSA sound driver and doesn't let go; I don't appear to have any applications that are using audio open, yet I still get this message: r@pal: ~$ aplay flugel.wav ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave aplay: main:545: audio open error: Device or resource busy So why isn't there a way to find what has tied up the audio device? If there is, great, now I can move on. I know multiple devices are supposed to be able to use the ALSA device at the same time, but I assume that older applications weren't implemented to take advantage of this feature, which is why I am receiving this error, no? I have always wondered about this; wikipedia says one of ALSA's main goals is "graceful handling of multiple sound devices in a system", but I have never known this to be the case. Time to restart my computer so I can use audio again.. regards, Rich

Analog and Digital Audio Signal Audio Info Resource?

by Christian Delahousse

Hi, I've noticed many posts on the list quoting ohm, K and other figures when refering to analog signals. Its making me realize that I know next to nothing about what's going though my wires as I record or patch. I do know about Hi-Z guitar connections, balanced connections, etc.. but just the basics not the specific details. The same thing goes for USB/Firewire/PCI interfaces. I keep on hearing terms like Bus Mastering and how USB devices have higher latency. I'd like to understand what these are and why this is. Does anybody know of a good online guide to walk me though all of this and explain the specifics and how it applies to audio. Google has not yield any good results. Thanks -Chris
