Getting Started
This chapter explains all of the MP-2's controls and connections.
Unpacking and Installation
Rack-mounting the MP-2
The MP-2 is designed to mount in a single rack-unit of (lu) of space in any standard 19"
equipment rack. Be sure that it is securely mounted using four standard (10-32) rackmount
screws.
About Tubes and the MP-2
The incomparable sound of tube amplification comes with the need for a small amount of
simple maintenance to accommodate the nature of tubes, which are somewhat fussier and
more delicate than the solid-state electronics used in the rest of the MP-2.
Tubes have a limited life span; it is recommended that the MP-2's tubes be replaced about
once every year, or if they show signs of wearing out. Some signs of degrading tube life are:
• "Ringing", squealing or feedback
• Microphonic effects (tapping on the MP-2 causes audible thumps)
Replace the MP-2's tubes only with high-quality, low-noise 12AX7A-7025 tubes. If desired,
these can be purchased from ADA (ADA part # 220020).
NOTE: To preserve tube life, allow time for the tubes to cool after shutting down the MP-2
before moving. Tube elements are more fragile when hot.
IMPORTANT: The MP-2 is designed to operate only at the voltage printed on the
back panel. It is not possible to change over or adapt the MP-2 to operate at any
other voltage.
Please use an appropriate external voltage converter when attempting to operate the
MP
