IA76 Posted September 15, 2009 Share Posted September 15, 2009 Hi We are after a better quality mic for our 100v PA system. We only use it for vocal stuff. We currently use an Audio Technica MB3K. What mic would you suggest up to £150 that will improve the audio quality? Thanks Link to comment Share on other sites More sharing options...
PoppaDom Posted September 15, 2009 Share Posted September 15, 2009 What is the current problem regarding 'quality'? 100v line systems are not renowned for audio quality and the problem may lie elsewhere... What is the rest of the setup? Dom Link to comment Share on other sites More sharing options...
J Pearce Posted September 15, 2009 Share Posted September 15, 2009 Whilst not amazing, I've never had much to complain about with the sound quality of MB3Ks when I've used them. I'd be looking at the other elements of your system. 100V systems can sound good, but many 100V products out there are made cheaply as they're mainly used for vocal paging for announcements and the like. Perhaps post model numbers and pictures of your amp and speakers and we may be able to advise where your money would be best spent for the greatest perceivable audio upgrade.

Simon Lewis Posted September 16, 2009 Share Posted September 16, 2009 I'm with Jon on this one. I've installed MB3ks as a cheaper alternative to the ATM33a (or whatever AT call it now). It works quite well. I would be suprised if it is the mic that is the limiting factor in your system, given the tendency for many 100V line components to have poor performance and restricted bandwidth. What does your system comprise of, and what specific problems have you identified? Simon Link to comment Share on other sites More sharing options...
IA76 Posted September 17, 2009 Author Share Posted September 17, 2009 All our PA system is Inter-M. We don't have any complaints about the quality but we just felt that if there was a way of improving it further by upgrading the mic we would try it!

Inter-M isn't 'bad' per se, but is built to a specification / application / price. A new microphpone may give you better sensitivity, polar pattern, feedback rejection etc. but the overall system quality will be dictated by the mic, amp and speakers and modified by the speaker placement and acoustic of the room.

johndenim Posted September 17, 2009 Share Posted September 17, 2009 What's the application please? I can only see 100v line P.A's in factories full of machinery. Link to comment Share on other sites More sharing options...
david.elsbury Posted September 17, 2009 Share Posted September 17, 2009 Or schools, hospitals, doctors surgeries, background music systems... they're everywhere, John! Link to comment Share on other sites More sharing options...
bruce Posted September 18, 2009 Share Posted September 18, 2009 .... churches..... and I've even seen one in a concert hall! Think of old buildings of architectural significance, where the speakers are chosen more on aesthetic grounds than acoustic, where there's no possibility of mounting a power amp close by, the cable runs are long and convoluted, and there's no opportunity to run chunky cables for low impedance speakers.

TomHoward Posted September 18, 2009 Share Posted September 18, 2009 All our show relays in our venue are 100V line systems as well, given the cable runs and numbers of speakers involved. Link to comment Share on other sites More sharing options...
johndenim Posted September 18, 2009 Share Posted September 18, 2009 Thanks for clearing that up! Link to comment Share on other sites More sharing options...
J Pearce Posted September 18, 2009 Share Posted September 18, 2009 The ease with which post-amplifier volume controls local to the speakers can be implemented is another real benefit to 100V systems. Link to comment Share on other sites More sharing options...
TimmyP1955 Posted September 19, 2009 Share Posted September 19, 2009 Although I have my favorite vocal mics, without proper EQ even the best is going to disappoint. Nearly all live vocal mics have a huge low mid/upper bass boost (proximity effect), and an upper mid boost (presence peak). Fail to use EQ to compensate for these anomalies, and one will have vocals that are both muddy and strident.
