is using the mic input setting as the input from a dj mixer dangerous???

why is the line input a lot less quiet than the mic input on my tx15's i want to play a large gig and i am wondering if it is dangerous to use the mic input as the input from my mixer

  • To put it in a simplistic way a microphone has a very low signal maybe only few microvolts so the mic input circuit is specifically sensitive for very low outputs so to feed a higher output from say a mixer would overload the circuit resulting in a very distorted signal, whereas a line input is rated at @ .75 volt specifically for the output from mixers, tape players and any outboard kit. If your want more power buy more speakers cabinets. If I was playing to 100 people with a bit of reserve allow 20 watts per person, so 2 kw worth of speakers cabinets is a ball park figure, so 250 people I would use a 5kw system. you might think thats an overkill but believe me when you need it you've got it. My system:- 21" Subs, 18" Bass, double 10" Mids, double compression horns for Tops, running 4 way active via amp rack.

    • At ear level for those in front ... maybe but you will still need subs to back it up, I have a close friend of mine who has 4 of these TX15 cabinets and was asked to turn it up after a big party that he had just done and realised that it didn't cope, people complained that it wasn't enough power so he asked me what to do without buying more cabs, the answer was to upgrade the 15" drivers better ones, we used Eminence Kappa PRO obviously 4 times the price compared with what was originally fitted (worth about £40 UK money), but the difference was worth the expense, but to really delight your audience you should invest in a couple of 18" subs.
      By the way I use PD drivers (Precision Devices) made here in the UK, just one 21" driver costs over £600 and it weighs 33 kgs (70Lbs) but they are so efficient yielding more sound pressure level which you can feel, yes you can buy cheaper drivers but they are 3 or 6dB down (every 3dB is doubling the sound pressure level) .... the subs cross over at 80Hz, Bass at 150Hz, mid range 150Hz to 2.8Khz via two 10" drivers, then the horns for the top end, no distortion only clean power. If you want a decent system you got to spend the doe.
    • thanks for the advice man. really appreciate it ill replace those drivers
