Hi gents at Bose,
Last weekend I connected an Oktava MK319 condenser to channel 1 of my PAS. No matter how I adjusted, the feedback was just intolerable.
How can I use the condenser for my 8-person choir without feedback ? Or using it for the acoustic guitar in place of the usual pick-up ?
Wow! A few months passed and no response?
I also setup the PAS in a 25-person choir, is that small or large?
We have a total of 6 microphones: two dynamic handhelds and 4 condensers. The 4 condenser microphones hang from the ceiling. Two mics hang in front, above, for choir row 1 and 2, pointing downward. The other two mics hang just above choir row two pointed downward to pick up the voice from choir row 3 and 4. All the mics go to a mixer, the LEFT main output of the mixer goes to the PAS.
All four condenser mics are about 18 inches away from the closest singer. I know this is not the way the PAS was designed, but it worked well for us - it's actually works better than our existing system! We position the PAS about 10 feet directly to the right of the choir. To be exact, it is about 10 feet directly to the right of row 2 of the choir. Admittedly, there is feedbacks, but that is acceptable because of the way we use the condenser mics. We had to play with the gain on the condenser mics to get it to the right level, but that's what we have to live with.
hope this helps.
Ooops. Sometimes we lose track of posts. We ask folks to "bump" or repost a question so that it pops back up in the "new since last visit" shortcut that most of us moderators use.
Great to see that you can help Andy out ... i wonder if he reposted somewhere else.
Just want to clarify what I take from your message. Are your condensers about 10-15 ft from the PAS, angling away from it ?
Another thing: I tested my condenser/PAS at home. Since the living room is only 14x14 was it a reason for feedback ?
...and so, you did try it at home!
I had the PAS setup in my 16 x 24 room, the PAS was too loud for the room even when I had the level at between 2 and 4. I didn't have my condenser mics at home and so didn't know if I would get any feedback.
Now, at church: We have the four condenser mics hanging from the ceiling with a curve at the end of right around 45 degrees so the mics can point at the direction of the singers. As I said before, the choir has 4 rows of singers. The first row has between 8-12 singers. If you are the right-most person (looking at the conductor), you can see the PAS stands about 10-12 feet to directly to your right.
Oh, I completely forgot, the PAS sounds much better when I had my B1 module unhooked. I have the LF setting on my remote set right at mid level. If I have the B1 bass module plugged in, then I have to set the LF on the remote almost all the way down. To me personally, the PAS even look beter and more compact without the B1 bass module.
I will need Someone-at-Bose to comment on my removing the bass module. Steve?
I'm not sure what you want me to comment on ... sorry. And what is the "LF"? Is that the "level" on the remote?
"Sounds much better" is a personal thing and a subjective matter so I'm not sure how I can help there.
Believe it or not, I don't even remember what's the label of those dial knob on the remote! My "LF" refer to the "Low" knob on the remote.
What I was asking your comment on was my not using the bass module. I search around this forum and don't see any reference on people not using the bass module. Maybe it's only me.
Now, on a different question that you can really comment on: As I was typing this message, a thought came up about using both channels of the PAS, where I would direct the output of the condenser mics to ch.1 and the output of the dynamic mics to ch. 2 and then use the EQ preset accordingly.
Another word, I would have the condenser mics pan hard left, then send the mixer's main left out to Ch. 1 on the PAS. Similarly, I would pan the dynamic mics hard right and send the mixer's main right to ch. 2 on the PAS. Am I getting nutty here?
Exactly! You've got! Use a small mixer and pan hard ... perfect.
As for going bass module free, Lee Flier of "What The...?" plays guitar and sings through her system without a bass module and likes the tone better. So yes, there are others that feel they don't need a bass module. I like a bass module with my system, I like getting a bit more of the fundamental.
I hope that helps.
Andy, I believe that Oktava mic is primarily for the studio. Studio mics are generally far too sensitive for most live work, and particularly with the Bose system. I have a really nice Lawson mic that sounds great in the studio, but unfortunately I can't get enough level with the system. The Shure beta 78 is a pretty nice condenser mic meant for live work, and it might work for your application.
