  2. #Description#

    What do you do when you need an extra microphone input but there's no inputs left on your sound system? Well, you could upgrade your mixer or amplifier and get a one with more inputs but that's such a shame when you already know your mixing device inside out and you only really need an extra input.

    The answer is to use a mic combiner and we are proud to recommend the AT8681 from Audio Technica. Audio Technica are renowned for quality in the microphone marketplace and the AT8681 2 into 1 microphone combiner certainly lives up to that reputation.

    The AT8681 is the ideal professional tool for combining two microphone into one input. It's a simple as that really, but there are a few things to consider before you pile in and start to share microphone signals.

    With regards to connecting this up, the AT8681 uses industry standard, 3 pin XLR connectors, for both the input and output of the microphone combiner. The unit can be installed anywhere in the microphone signal chain making it ideal for use near to the mixer or amplifier but just as happy right there at the microphone position on stage.

    You're going to need to make sure that phantom power is available as it does need this to work. Good thing is that the phantom power voltage from the mixer is also sent on to the microphones and it can work from any voltage between 24v DC and 48v DC making it compatible with just about all commercial and professional audio devices.

    From a quality point of view you're not going to find better than the Audio Technica AT8681. It's rugged steel housing adds to it's robustness providing a long service life in all applications. The AT8681 can also be permanently mounted via the mounting holes on the side of the metal housing making ideal for the installation market including houses of worship etc.

    The unit offers a balancing control to allow you to tweak the audio between the two microphones which sets this unit above others in the marketplace.

    So just to summarise how to use this item...

    You will need a microphone input on your sound system that has phantom power available. The output of the Audio Technica AT8681 is then connected to the mixer input using a balanced XLR lead. You can then plug microphones into both inputs on the combiner and the audio is merged together and sent onto the mixer ready to be broadcast over your sound system. You can use both dynamic and condenser microphones thanks to the phantom power pass through facility. Finally, adjust the balance between the two microphones by using the small rotary control on the AT8681.

    That's it, your all set up and ready to mic share from two microphones into one input. Best of all you've saved yourself the hassle and expense of upgrading your mixing equipment.
