Welcome to the Analog Sound of the MP -A Series. This is an all tube product, and there are some
basics you should come to understand before using this product for the first time.
Tubes are a component that have specialized and unique features. If you are a "pre" or baby boomer,
born before 1957, you may recall using tubes in various products, such as radios, amplifiers, and
televisions. So, this is just to refresh your memory. If you are a "post" baby boomer, this could be your
first experience with tubes, so please pay close attention! (You will be tested at the end of this manual).
Tubes are most efficient and effective when "warmed up." This means, upon starting the MP-A Series,
you should allow the tubes to become fully heated before attempting to operate. The minimum amount
of warm up time is approximately 15 to 20 minutes.
Set up your instrumentation layout before powering up the MP-A Series. Plug in your instrument or
microphone while the unit is off. This will prevent unwanted noise such as "pops." The same applies
when you shut down. Allow a minimum of 25 seconds for the power to drain from the tubes properly.
Then you can unplug your instrument or microphone. Always turn your Phantom switch to the off position
before plugging or un-plugging your Microphone.
Placing the MP-A Series in a rack, we recommend using the first tier or allow one x space in order to
properly ventilate. Avoid overheating! Too much heat will reduce the life-span of your tubes. We also
recommend strongly that you observe SPL and shock mount any tube product.
A Designs has scoured the earth for the perfect combination of tubes for this unique quality sound. Go
ahead, get started. Read the following pages carefully to become acquainted with the warmth and clarity
that the MP-A Series can deliver to your recordings.
Please feel free to email A Designs via the website with any creative applications for the use of the MP-A
Series. We have included some applications in this manual. We may just include your suggestion on our
website!
Congratulations on the purchase of your MP-A Series all tube microphone preamplifier!
Most of all have fun.
