INTRODUCTION GOLDMUND METIS 7 Integrated Amplifier Goldmund was founded in 1978 and has ever since been dedicated to the accurate reproduction of sound and image. At Goldmund, we strive to lead in the creation, development and manufacture of the industry s most advanced technologies, including audio and video systems. The guiding principle at Goldmund is to produce a precise sound with the least possible loss of quality through the different stages. Goldmund will never adopt a technology before it is sufficiently developed to satisfy the high quality standards we set. This is why Goldmund has often rejected mainstream technologies and developed its own. GOLDMUND METIS 7 Integrated Amplifier - 1

1 SETTING UP THE METIS 7 1.1 PRELIMINARIES Please read the following instructions very carefully. This high-precision unit will provide the best signal possible to your speaker, 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 source such as the Eidos 17 Universal Player. The connection between the analog and digital sources and the Metis 7 as well as between the Metis 7 and the speaker 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 Metis 7 is designed to provide. In all typical cases Goldmund recommends using the special Goldmund Lineal interconnect and digital cables. 1.2 UNPACKING WARNING If you need to return the Metis 7 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 Metis 7 in transit. Use of alternative packaging is likely to result in damage, invalidating warranty cover. You will find in the packaging: - The integrated amplifier 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 METIS 7 (Ctd.) 1.3 CHOICE OF THE METIS 7 LOCATION Select a very rigid support, as required for your player transport. 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. If you want to achieve the best possible sonic result, select an opposition on a shelf or on a piece of furniture where the Metis 7 is isolated from vibrations of mechanical components, including the player transport itself. 1.4 POWER SUPPLY The Goldmund Metis 7 uses an internal power supply developed by Goldmund to provide totally separate voltage between the USB part and the digital/analog circuitry. Your unit has been set to operate with the mains voltage of your area. Check on the power supply voltage switch on the rear panel if there is any doubt. If you move after purchasing the Metis 7 to an area using a different AC mains voltage, you can change the voltage yourself or consult your local Goldmund dealer for assistance in doing so. The voltage selector on the rear panel allows choosing between 220V (234V nominal) and 110V (117V nominal). In case the nominal line voltage in your country is out of range, please consult your local Goldmund dealer for assistance. The power supply unit can operate indifferently with both 50 and 60 Hz AC line. GOLDMUND METIS 7 Integrated Amplifier - 5

1 SETTING UP THE METIS 7 (Ctd.) 1.5 FIRST INSTALLATION & CONNECTIONS Connect the power cord to the back of the integrated amplifier and plug it into the nearest wall plug. For safety reasons, use only a 3 lugs grounded plug. To get the best sound from the Metis 7, avoid any multi-way plugs or extension cords. NOTE A USB driver needs to be installed on your computer before to use it as a source with your unit. Mac and Linux operating system do not need driver to be used with the Metis 7. Connect a computer, CD/DVD or Blu-ray player to the back panel of the Metis 7, using either the USB Audio, Toslink Optical, RCA Digital or RCA Analog connectors. When the input source is connected, connect your Metis 7 using the two speaker output connectors located on the rear plate of your unit. Select one of the 3 available inputs for listening using the front input switch. Only one connection per input can be used at once. The Optical Toslink input has the priority on the RCA Digital input, in case you want to use the Digital input, unplug the Optical cable from the digital input. AT T E N T I O N: A residual high frequency noise may remain audible in some circumstances if an analog input is left open and is selected. This disturbance has no effect on the amplifier but may be avoided easily through the application of short-circuit plugs on all unused inputs. GOLDMUND METIS 7 Integrated Amplifier - 6

2 OPERATING THE METIS 7 2.1 FRONT PANEL FUNCTIONS INPUT SOURCE SELECTION The back panel inputs are selected by selecting the 3-positions switch on the front panel. When the digital input has been selected, the orange led will be displayed on the front panel only when the digital source has been locked to the source frequency. In analog and USB input the orange led is always on. OUTPUT VOLUME ADJUSTMENT The level control may be adjusted manually with the front panel knob or by remote control. It acts for all channels simultaneously. 2.2 REMOTE CONTROL Your Metis 7 has built-in remote control for volume and mute.
