Ben. Posted March 23, 2008 Share Posted March 23, 2008 Hi all, Looking for a delay unit to put in the audio signal chain in a church system, basically to try and sync the visuals and audio better. It is for a seperate room that is being sent audio and visuals to the main church, hence real time not being crucial. Just wondering what units anyone would suggest using, or if anyone knows of anything that can just alter system delay. I'm not sure if there is anything other than multi effects units that are avaliable. Thanks Link to comment Share on other sites More sharing options...
Shez Posted March 23, 2008 Share Posted March 23, 2008 Any loudspeaker management system will offer that functionality. Offerings from DBX are worth investigating; also Behringer's offerings. Maybe even behringer's shark - I've used one a few times for problem solving tasks like that & it won't break the bank. Link to comment Share on other sites More sharing options...
paulears Posted March 23, 2008 Share Posted March 23, 2008 If you're having to delay the audio to match the picture - you may find that if the delay is significant, the people speaking might find it difficult to work with - but feedback may well be a thing of the past!

techywhizz Posted March 23, 2008 Share Posted March 23, 2008 I've had problems withthe behringer shark ... the delay time resets everytime it is power cycled.. We use a small kramer stereo delay which works fantastically to sync the video and audio http://kramer-uk.com/indexes/item.asp?name=VA-256 Link to comment Share on other sites More sharing options...
Ben. Posted March 23, 2008 Author Share Posted March 23, 2008 Thanks for all the replies so far...... Any loudspeaker management system will offer that functionality. It's cheap and nasty loudspeakers at the moment, they are in the process of upgrading, but as far as I know peavy don't offer a loudspeaker management system the people speaking might find it difficult to work with Mentioned in the original post that the delayed signal will be sent to a second seperate venue to the main venue, so it's just a relay system in essence. I'll have a look at the mentioned delay units, if anyone has any more that would be most appreciated. Link to comment Share on other sites More sharing options...
Lamplighter Posted March 23, 2008 Share Posted March 23, 2008 BenTechywizz must have been unlucky, I used a Shark as a fixed delay for several years before going digital, never lost the setting and it was always powered down between shows, sometimes for months. It has a latency of around 11 mS but this should not be a problem in your application.Brian Link to comment Share on other sites More sharing options...
Simon Lewis Posted March 23, 2008 Share Posted March 23, 2008 It has a latency of around 11 mS but this should not be a problem in your application. I'm glad someone else has measured this! I suspected that the feedback destroyer function wasn't so much the large chunk of the audio spectrum it removed, but the fact the the processed signal got moved to a different time zone ;-) Ben, do you know what length of delay you need to apply?

Ben. Posted March 23, 2008 Author Share Posted March 23, 2008 Ben, do you know what length of delay you need to apply? Simon Hi Simon, Havn't measured it yet, but at a guess somewhere around 60-100 ms Thanks. Link to comment Share on other sites More sharing options...
Simon Lewis Posted March 23, 2008 Share Posted March 23, 2008 Havn't measured it yet, but at a guess somewhere around 60-100 ms Well, the Shark is cheap and cheerful, and it will certainly give you you that range of delay. I haven't had a good experience with its feedback destroyer function (read - still wakes up in a cold sweat thinking about it!). Simon Link to comment Share on other sites More sharing options...
Lamplighter Posted March 23, 2008 Share Posted March 23, 2008 I'm glad someone else has measured this! SimonIf it is of interest the actual figure was 11.4mS using Smaart. It is a shame that I ran out of computers to download the demo software as it is somewhat outside my budget for occasional use.Brian Link to comment Share on other sites More sharing options...
Stuart91 Posted March 23, 2008 Share Posted March 23, 2008 Techywizz must have been unlucky, I used a Shark as a fixed delay for several years before going digital, never lost the setting We've had a similar problem recently, with a church where a Shark had been used as a cheap'n'cheerful delay unit. It has worked perfectly for several years, then recently it somehow reset itself to a stupidly long delay time. (The church service descended into farce until someone worked out what was happening) Our theory is that the unit freaked out due to some sort of mains anomaly. It's continued to work fine once the correct setting was reinstated, although I'll be very interested to see how it gets on from here... Link to comment Share on other sites More sharing options...

Witness their company acquisitions.... Link to comment Share on other sites More sharing options...

It might be worth checking to see if there is an internal backup battery. This could need replacement soon. Cheers James. Link to comment Share on other sites More sharing options...
CRandall Posted March 25, 2008 Share Posted March 25, 2008 Peavey's Architectural Acoustics range has some very useful equipment . I have been using the Peavey IDL-1000 successfully in my church for a couple of years. It is from their Architectural Acoustics line and is simple to setup and reliable. It is only 16bit, but the dynamic range will be good enough in most applications unless you have a very quiet building. I bought it fairly cheap on eBay. I am planning to upgrade to Media Matrix X-frame units (also bought on eBay and then refurbished) as part of a wider refurbisment. They are excellent units and can be made to do almost anything, but I don't recommend these unless you are comfortable working with advanced software defined systems.
