Allow the MPC-100A to warm up for at least 15 minutes before using it in your
processing chain. The tubes and other circuitry need time to reach an electronic
equilibrium before they will operate at optimal specifications. For the longest life, it is
recommended that you turn off the unit when it is not in use.
Please mount the unit in your rack, making sure that there is sufficient ventilation,
especially on the right and left side of the chassis. The MPC-100A will generate a
significant amount of heat; therefore, it is necessary to have good air flow to prevent
damage to your MPC-100A or any other pieces of gear housed in the rack with it.
The tubes in your Summit Audio MPC-100A have been intensely screened for
desired distortion and gain characteristics. We recommend that you do not replace the
tubes with “guitar amp” tubes. Please consult your dealer about availability of
appropriate replacement tubes. These can also be ordered directly from Summit Audio.
Please fill out the enclosed warranty card. If you have any questions about the operation
of your MPC-100A, please do not hesitate to call our customer service department at
