1 SETTING UP THE MIMESIS 32.5 1.1 PRELIMINARIES Please read the following instructions very carefully. This high-precision unit will provide the best digital signal possible to your digital-input power amplifiers thanks to its unique technology. For exacting technicians, musicians, and all high-fidelity music purists who demand the very best in musical reproduction, we strongly recommend the use of top quality power amplifiers with a digital input, since most of the digital signal performance delivered by the Mimesis 32.5 acoustic processor can be eroded by using lower quality amplifiers or D/A converters. The connection between the analog and digital sources and the acoustic processor as well as between the Mimesis 32.5 and the power amplifiers are critical. Ultra low reflection interconnect cables are absolutely mandatory in analog and precise impedance SPDIF cables in digital to keep the time integrity that the acoustic processor is designed to provide. In all typical cases Goldmund recommends using the special Goldmund Lineal interconnect and digital cables. WARNING If you need to return the Mimesis 32.5 to the factory or to your local representative for a warranty repair; please note that it must be repacked in the original packaging. This packaging has been designed specifically to protect your Mimesis 32.5 in transit. Use of alternative packaging is likely to result in damage, invalidating warranty cover. 1.2 UNPACKING You will find in the packaging: - The processor itself - The power cord - The remote control - This manual Unpack the above-mentioned parts carefully, keep all packaging for future use.

1 SETTING UP THE MIMESIS 32.5 (Ctd.) 1.3 CHOICE OF THE MIMESIS 32.5 LOCATION Select a very rigid support, as required for your player transport. The distance between the Mimesis 32.5 and the power amplifier is usually not critical since the signal is carried in the digital domain. However, you must use coaxial links of highest quality such as the Goldmund lineal in order to maintain the time accuracy and are highly recommended, especially for long distances. For some high impedance output analog sources, a short distance to the acoustic processor is mandatory. If you want to achieve the best possible sonic result, select an opposition on a shelf or on a piece of furniture where the acoustic processor is isolated from vibrations of mechanical components, including the player transport itself. The Goldmund Mimesis 32.5 acoustic processor generates a significant amount of heat. It is necessary to allow adequate ventilation for proper cooling of the heat sinks. Avoid any location which is not properly ventilated. Avoid stacking equipment and do not locate the acoustic processor close to equipment that is sensitive to temperature. 1.4 POWER SUPPLY The Goldmund Mimesis 32.5 uses multiple power supplies developed by Goldmund to provide totally separate voltage to each part of the digital and analog circuitry. Your power supply has been set to operate with the mains voltage of your area. Check on the power supply voltage switch if there is any doubt. If you move after purchasing the acoustic processor to an area using a different AC mains voltage, consult your local Goldmund dealer for assistance. The power supply unit tolerates both 50 & 60 Hz mains. GOLDMUND MIMESIS 32.5 - UNIVERSAL ACCOUSTIC PROCESSOR - 5
