Have a question? Chances are someone else had a similar problem.
1. Is UHF wireless better than VHF and do I really need one with user selectable frequencies/channels?
There is no difference in sound quality when comparing VHF to UHF transmission. What you should be concerned with is the over crowding of both of these frequency bands. That's why we recommend a frequency selectable system to assure years of trouble free use.
2. When people speak at the lectern the sound seems to drop off if they turn their head or move around. Is there a fix for this or do we need a new microphone?
Chances are the pickup pattern of the microphone you're using is the wrong type for the job you're asking it to do. We offer specialized microphones for use at the pulpit. Give us a call and we can determine the right one for you!
3. I think we may need a new amplifier. When we turn it on buzzing & cracking sounds are heard. What should we be looking for in a new one?
It depends on your requirement but generally speaking, be sure the rated output of the amplifier matches the speakers program rating plus a little extra for headroom. Most loudspeakers are damaged because of under powering with an amp that's too small than over powering so be sure you have enough power!
4. Our church recently purchased new, high quality (and very expensive!) microphones for the pulpit, altar and lectern but it still doesn't sound that great and we sometimes get feedback. We have an 8-channel mixer, amplifier and a pair of speakers. HELP!
It sounds like you may need a graphic equalizer. This tool would allow you to shape the tone of your sound system as well as make adjustments to problem frequencies helping to minimize feedback.
5. When our pastor uses his wireless lapel mic we can't turn it up loud enough without getting feedback. Also, it sounds muffled. What are we doing wrong?
Chances are it's where it's being placed. Too close to the neck will cause the sound to become muffled, too far away and it will sound hollow. I typically recommend a distance of FOUR fingers down from the bottom of your chin. Also, an omni-directional mic is very difficult to use in live sound reinforcement. We typically recommend a cardioid pattern or if you're in a high gain (loud) environment prone to excessive feedback a super-cardioid pattern might be better.
6. We have speakers throughout our building (nursery, classrooms, cry room). We want to add a couple more but were told we need to get speakers with transformers. Could you please explain?
By using a constant voltage line you can add as many speakers as you have power without regard to ohms/impedance. Check to see where your current speakers are "TAPPED" (they will be connected to a specific color wire on the positive (+) side, and that color wire will be referenced to a specific wattage) then multiply the wattage tap by the number of speakers. Compare this number to your amplifier's power rating to determine how many more speakers you can add. Typically you want to leave about 10% of the power as "reserve" for line loss in the cable.
7. I am the music director at my church. I want to use CD's that have the music on one track and voices on the other track. I would like to have individual volume control of the two tracks; do I need a special CD player?
Your current CD player will work just fine for this. There are small cost-effective devices, which your CD player will plug into and provide a separate volume control over each track. Give us a call; we can recommend the right one for you.
8. When we record services for our tape ministry the pastor comes across loud and clear but we can't hear the choir that well. We tried using a pair of hand mic's we have but still couldn't get them loud enough on the recording without getting feedback.
If you only need to get the choir to tape and not the room, try assigning the choir mic's to the "Record Bus" only. If available, an "aux" send from your mixer can be a discrete mix only for recording. This will allow level changes to the tape without changing the level in the main system. We've had tremendous success with both hanging choir mics and especially side-address, large diaphragm studio condenser types.
9. There are so many choices when it comes to speakers, how can we be sure we're getting the right ones for our church?
There are many factors to consider (too many to get into here). The most important will be dispersion and power/sensitivity. You will need to determine where the speakers will be located (left/right sides or center etc.) then you can determine the appropriate dispersion to cover the listening area. Loudspeakers commonly come in 60° and 90° horizontal dispersion. Knowing this ahead of time can help decide on speaker placement. Determining power requirements is a bit more complicated. Suffice to say, always use the speakers "PROGRAM" rating when matching to an amplifier. Check out FAQ #3 for powering tips.
10. I have a surge protector for my computer. Do you recommend using one (or more) for the sound system equipment? If so, is there anything specifically designed for this type of equipment?
Yes, absolutely! We mainly use surge protection for processing equipment (Mixer's, EQ's etc.). There are also power sequencers which power equipment on and off in a particular order to protect speakers from electronic spikes also there are voltage regulators, which provide an extra degree of protection for digital equipment.
