Hello & PA setup advice
Hi folks, looking for a bit of advice. I've tried googling, etc but I'm clearly a bit slow in pa terms as getting confused and need to make sure this is right! So would appreciate your advice chaps.
My band have been using an active speaker setup for the past couple of years.
The BlackBeez - Premier Wedding & Function Band
if you want to check us out:-)
We've just upgraded to a new PA system package, and I want to make sure I'm getting the setup right (prior to blowing anything up!).
Ok, so we have bought:
2 x Peavey Pro 15
2 x Peavey Pro Subs
W Audio DA 1300 amplifier
behringer 2222fx mixer
The Peavey Pro 15 specs are:
300 Watts RMS continuous, 600 Watts program, 1200 Watts peak
The Peavey Pro Subs specs are:
The nominal impedance of the Messenger Pro™ Sub is 4 ohms.
We have equipped the Pro™ Sub with a high pass output socket. This provides a filtered output signal for operating a satellite enclosure with a minimum impedance of 4 ohms. The design of the crossover ensures the total load presented to the power amplifier is never less than a nominal 4ohms.
The full range signal from the power amplifier is connected to the input of the Messenger Pro™ Sub. The full range signal from the power amplifier is filtered by the Messenger Pro™ Sub onboard crossover into a high and a low signal. The low pass signal is supplied to the woofer in the Messenger Pro™ Sub, high pass signals are supplied to the satellite and filtered again by the satellite’s own passive crossover.
The W Audio amps specs are:
Stereo output @ 4 Ohms: 650W x 2
Stereo output @ 8 Ohms: 390W x 2
Bridge output @ 8 Ohms: 1300W
So, I'm a bit concerned about about the whole ohms / amp scenario.
As I understand it, I can run the two pro 15's, each one through a separate channel on the amp, and that will be fine.
My concern is adding the two subs into the equation; will this not reduce the ohms down to 2 ohms, and with the amp being 4, will that not cause damage?
However, I have found a company posting a vid on youtube on this very system saying it's fine
(it's on youtibe as 'Peavey PRO 15 & Peavey PRO SUB Demonstration from Get in the Mix featuring DJ Tutor - YouTube')
Thoughts/advice much appreciated guys, thank you.
