It's a mind-boggling question if you don't know the answer, but it's actually quite simple to decide. A PA system only needs one source of power amplification.

Powered speakers contain their own amplifiers (and plug into the mains as well as the mixing desk), so you don't need a separate amplifier, and you would choose a passive mixer.

If you choose passive speakers (which don't contain amplifiers) you need some other source of power, so you can choose a powered mixing desk with an amp built in, or a passive mixing desk and a separate power amplifier. If you want to install the system (wall-mount the speakers and hide the wiring) then you are best off choosing passive speakers with either a powered mixer or a passive mixer and a power amp, as passive speakers are lighter.

If you know what you want you're welcome to Pick'n'Mix or you can take a look at the off-the-shelf PA Packages in the online shop - you'll find they're cheaper than buying the items individually. If there's nothing suitable, we can put together a custom package for you. All our packages are bundled with speaker stands, but we can replace them with wall brackets if you prefer. We don't include microphones in the packages because everyone's needs are different.

Mixing desks look complicated but they aren't really. If you look at it, there are columns of knobs and sliders (on the left two thirds) which are all the same. Each column is called a channel. Each microphone, instrument or CD player plugs into one channel, and the sliders and knobs control the volume, tone and special effects for that channel. If you label them MIC1 MIC2 CD PLAYER etc, it's easy to see what you're turning up or down, on or off. The right hand side has the control knobs to set the special effects and to take the sound out to headphones or monitors. We can supply you with an easy Set Up and Usage guide so there's no need to worry.

A wireless microphone system is also known as a Radio Microphone. You can get handheld, headset and lapel microphones, and can have any number and any combination of them. Handheld mics are best for singers, or if you need to pass the microphone around. Lapel mics are best if the speaker needs to use their hands and won't be moving their head around very much. If your speaker is animated, headset mics are best because they move with the head.

Wireless microphones all come with a receiver box which you plug into the mixing desk. Handheld mics contains a battery and a wireless transmitter which sends the voice signal to its receiver. The Lapel and Tie clip versions connect via a short wire to a Belt Pack Transmitter which sends the signal to its receiver, which is then broadcast from the PA System.

Some wireless microphone systems come with one receiver and two microphones - these are called Dual systems. Some wireless microphone receivers can be built into the PA System, such as that in the Portable PA the TEC076.

The cheaper wireless microphones come with only one channel, which can cause you to get interference and signal drop out if you are near other radio signals, such as those from taxis, fire engines, police cars or ambulances. The better mics have 16 or more switchable channels, so you can choose one with no interference.

If you want microphone stands with your handheld mics you need to buy special microphone holders for them, because the barrel of the mic is fatter than a regular, wired microphone.
