Like normal speakers, studio monitors come in both active and passive models, with active models being somewhat more common (at least for those who aren’t inclined to mess around with watts and ohms and such).  One distinct feature of many active Studio Monitors is bi-amplification.  This in essence means that the high and low frequency drivers (tweeter and woofer) each have their own, separate amplifiers specifically designated for their respective frequency ranges – with the audio signal being first run through a 2-way crossover.  This allows for higher quality audio and allowing more refined amplification of the specific frequency ranges.

No, not at all. The WM60 (mono) and WM70 (stereo) transmitters can be used in conjunction with our WM40 and WM400 receivers. The WM40 are design specifically for our Performer Active speakers, however the WM400 can be connected to any Active speaker, preferably with XLR inputs.

The 3 numbers you refer to (300/600/1200) are actually the RMS/Program/Peak power handling wattages of a speaker. The RMS (which is also known as continuous power) value could be described as the power handling of the speaker if a constant sine wave was sent through the speaker for a long period of time. It is not a real indication of the power handling of the speaker when real music is fed to it, though. The Program value is based around the occurrence of a complex program signal being sent through the speaker (ie. more like real music). The Peak is the absolute maximum power handling (but only for extremely short periods of time). Of course typical audio signals are ever-changing, so the power should generally be somewhere in between the RMS and Program values.

1. Always try to position the speakers so that they are in front of all microphones, pointing away from them. If you point speakers back at you, it will almost certainly cause feedback. If you have to point them back at you, try to position them to point directly at the back of the mic.
2. Make sure all mics are positioned correctly. One mic out of position can cause the whole problem.
3. Listen for the frequency of the feedback and try to adjust the EQ accordingly; if you’re getting low end rumbles, turn down the bass on your mic channel or graphic EQ. If you’re getting high squeals, turn down the treble on the mic channel or graphic EQ, etc.
4. You may need to add a monitor system so that you can hear yourself better. You can power these from your mixer, or use active stage monitors, and EQ them separately from the mains in order to maximize levels before feedback occurs. Point these back at yourself at ear level and you can turn down your mains to control the feedback better.

Q: I am interested in getting a wireless PA set up for outdoor use. Can you tell me whether your transmitters/receivers will work with any speakers/mixers? Do the transmitters/receivers work with stereo signals? Also if I wanted to use a surround sound set up would that be possible?

Q: The manual states that I can connect an electric bass guitar to an HI-Z or Super Hi-Z channel. I assume the Powerpod can handle that , but can the SEM715 handle the Low of the Bass as well? I also want to know if I can Use different effects for each channel , and how can I do that?

Q: If we have multiple wireless Performer speakers in three or more areas, can we transmit to each independently or will every speaker pick up what ever is transmitted, all the time.

If you want to use your P6A to play live music, preferably, you should have a sound card or Audio/Midi interface with 2 outputs (L & R) to connect your speakers to your Mac/PC. If you don’t have a sound card with this feature, you might need a mixer. However you can also buy a special y-cord (single to dual) with a mini stereo jack on one side, to plug into your notebook, and 2 phone jacks on the other (or possibly RCA) to connect the P6A. This cable can be found at most electronics shops.

The Performer speakers can transmit through walls, provided that they are not solid cement or thick steel or anything similar to that.

If you want to daisy-chain 3 PA550 together, the main input signal must go” Input 3″ Via 1/4″ jack and then to the next PA-550 via the “LINK OUT” XLR into the next input 3 jack.
