Massive Pop at start-up

[Holland]

I just installed a new system in the studio which is a G-5 with HD-3 and a Control 24...... Mackie HR 824 speakers.... When I fire up the control 24 even with the Mackies OFF there is a massive pop that comes thru the speakers!!! Yes I said WITH THE MACKIES OFF.....!!! What is the cause of this ???? Please help.....

Hi,

Either you have polterguise in your studio or you are not waiting for your powered monitors to turn off completely!

Turn all your gear on first! including control 24,wait for everything to boot-up!! then turn on your speakers and sub woofer!!. better still have all your monitoring & appliances on one seperate power supply and turn this on way after everything has booted.

I have a C24 and the Mackie 824's and I get a loud pop, but only if I have the Mackies on. I use a Monster power center that powers up the Mackies three seconds after the C24 is powered up and it still pops. So, it must take more than 3 seconds to power up the C24 completely, but I don't have your problem.

Check the rear power switch of the Mackie's, there's a couple of different settings it can have, so try a different one and see if that works.

There is only ONE way !

When powering on the C24 you must wait at least 10 seconds before turning on your speakers/amp.

After the initial handshake on startup (all leds on and off quickly), wait until you see the main ouputs leds lit.

It's often during this last step that the C24 can make a loud POP.

You should not get any problems.

And one more way.... leave it turned on! Turning it off and on is undoubtedly harder on it than leaving it to run. We leave all 3 of ours on constantly.

FWIW.
