Behringer MX802A line inputs
There was recently some discussion here about the line level inputs on
the small Behringer mixers, specifically the 802, and whether they use the mic preamps or bypass them completely. I haven't been able to find an answer to this. Anyone know for sure how they route the signal? Thanks. |

I haven't been able to find an answer to this. Anyone know for sure how they route the signal? Since the stereo channels don't have mic preamps, it seems like it would be quite obvious that their line inputs don't bypass any mic preamps, since there are no mic preamps to bypass. You may be thinking about the two mono channels with mic preamps. Typically low and mid-end mixer line inputs don't bypass a given mixing channel's mic preamps when that mixing channel has mic preamps. This is true of the Behringer and Mackie mixers for which detailed block diagrams are available, for example. |

If you don't like it, inject the signal into the insert, after the mike preamp. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Behringer MX802A line inputs
This particular mixer doesn't have inserts, and the two stereo
channels don't have preamps - but neither do they have sends. After that previous discussion mentioned (in which I took part) I have decided that I am going to find a better way to do this, because, as Mr. Boyke points out, that Behringer pre is messing up my nice RNP'd signal. I simply don' have time right now to experiment, but when I do I will try to contribute some questions and perhaps some comments. d (Scott Dorsey) wrote in message ...

If you run the RNP signal through it on the way to your recorder, you're gonna screw up the signal. G Yeah, I guess you're right Steve. I was just thinking it might make routing the signal a little more flexable by leaving the RNP connected to the 802. I know someone suggested using a line mixer for this and I was wondering if the 802 line inputs would do the same thing. No big thing, I'll go direct with the RNP. I might be getting a small acoustic amp so maybe the 802 will be useful with that. Thanks. |

Twist the little black preamp gain knob while you are plugged into the
line level input. Hear that? That's messing us up, George. d George W. wrote in message . ..

Dan, I assume you're referring to the RNP when it's connected to the mixer. With everything up on the mixer it's pretty loud but when I run the RNP direct to the soundcard and turn the gain all the way up I still get some hiss. I have to turn up the volume louder than normal (about 1/4 of the way) but it certainly isn't dead quite. I imagine it's unrealistic to expect it to be but how much noise would be "normal" for the RNP? I found that noise other than hiss on the RNP is very much dependant on location. I had it about a foot from the PC monitor but got a pretty obvious buzz with the gain turned up. Moving it a couple of more feet helped. I'm gonna have to re-think the location of some components and perhaps try some better cables. I'm using regular RCA audio cables with 1/4" adapters on the RNP side. Along these lines I'd appreciate any input by anyone on whether the RNP is working as it should be. Thanks. G. |

Yeah, that hiss and the gain that it is accompanying is proof that the
MX802A preamp is part of the circuit - that's the preamp gain knob. Any hope that the preamp is out of the circuit when using the line-in is dashed. My RNP will also hiss when turned all the way up...I bet most pres do. The RNP is known to be slightly noisier than some other preamps, but as some have observed, even its noise is way less than that of some treasured vintage preamps in use by professionals daily (also, see McQuilken's accomanying package notes on design/price trade-offs). Its nothing compared to the noise you and I will add to the chain with our PC monitors, PC fans, questionable acoustic treatment, and whatever else. My set up is so claustrophobic that I sometimes just turn my monitor off and on again as needed while tracking to eliminate hum - I use keyboard shortcuts, and don't always have to see. Get this, my studio is in a square, untreated home office shared with my wife, who works full-time at home, in that office, and often into the evening, with 4 PCs networked and humming 24/7. ****ing terrific environment. but we'll maybe be moving soon, so I'll be on the lookout for a garage type space. That PC monitor is going to bleed into everything, it will even affect your monitor speakers - many studios use active matrix/flat panel/LCD monitors to avoid most of this.

If you do, something else is amiss. The RNP I tried had a bit more noise than other quality preamps, but it's not really noticeable at moderate signal levels. You might want to purchase a pair of higher quality cables to go between the RNP and your soundcard. Keep the cables away from the CRT as well as any 120v lines (or if you have to have them near 120v lines, cross them at 90 degrees - don't let them run parallel). Now all you need to do is figure out how to get rid of the CPU fan and hard drive noise. I solved it by moving the CPU (a G4) into the next room - cut a 2" hole through the wall and got some extension cables - stuffed the hole with foam = works great). -- Stephen T. Boyke |

I get the feeling there's no light at the end of this tunnel. g Thanks for the cable advice. I've got some RS RCA cables with 1/4" adapters on one end so I'll see if I can find something better. Moving the RNP away from the monitor helped a lot. Thanks Steve. G. |
