USER MANUAL
GOLDMUND Metis 5
Analog Integrated Amplifier

Thank you for purchasing the Goldmund METIS 5 Analog Integrated Amplifier. The Goldmund
Metis line amplifiers fully incorporate the technological expertise developed by our company
throughout many years. Please take some time to read this manual. It will provide you with useful
information to make your pleasure of listening to the Metis 5 even higher.
INTRODUCTION
GOLDMUND METIS 5 Analog 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.

W A R N I N G !
This high quality amplifier possesses new
technical features such as ultra-high band
width and computer linking which are
necessary for accurate transcription within
today’s best audio systems.
Only careful use can provide all the
satisfaction you are expecting.
All handling must be performed according to
the following instructions to avoid impairing the
amplifier’s performance.
Nevertheless, if the instructions are perfectly
carried out, you will notice that the use of the
GOLDMUND METIS 5 is quite simple and
convenient.
IMPORTANT
PLEASE DO NOT CONNECT ANY CABLES
OR MOVE ANY PARTS BEFORE READING
THE FOLLOWING INSTRUCTIONS.

UNPACKING
You will find within the custom
packaging:
- The Metis 5 amplifier,
- The remote control & batteries (to be fitted before use),
- The power cord,
- This owner's manual.
Unpack the above-mentioned parts carefully.
Keep all packaging for future use.
WARNING
If you need to return the Metis 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 Metis 5 in transit. Use of
alternative packaging is likely to result in damage, invalidating warranty cover.
2 AMPLIFIER LOCATION & COOLING
The Metis 5 amplifier, like all high quality amplifiers, generates a lot of heat when driven at
high levels and therefore must be vented properly.
It is mandatory to allow proper cooling of the heat sinks.
Do not put temperature sensitive equipment on top of the amplifier.

3 CONNECTIONS & LINE VOLTAGE
Connect the power cord to the back of the 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 amplifier, avoid any multi-way plugs or extension cords.
• Connect the speaker cables to the binding posts on the rear panel.
• Connect the interconnects from any analog sources to line inputs 1 to 5.
AT T E N T I O N
A residual high frequency noise may remain audible in some circumstances if an 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.
LINE VOLTAGE
The Goldmund Metis 5 integrated amplifier is preset at the factory for your country's
voltage. It functions with AC voltages between either, 211V and 257V, or, 105V and 129V.
If your AC line is usually out of these tolerances, please consult your local Goldmund
dealer.
Please check the value of the mains line fuse. This fuse is located in the power cord
receptacle. The lid can be removed with a small screwdriver when the cord is removed.
Use a 5A slow-blow fuse.

4 AMPLIFIER CONTROLS
POWER
The METIS 5 integrated amplifier is powered on using the switch located on the back
panel. In regular use this switch should be left ON at all times (see sound quality
optimization). The standby function of the remote control should be used to mute the signal
for safe removal of cables. When in standby mode the front panel operation LED will stay
lit.
The amplifier is powered OFF by switching the back panel switch to the OFF position. A
safety circuit switches the unit to mute to avoid any disturbance reaching the speakers.
MUTING
To mute the preamplifier output, press the "MUTE" key. The same operation repeated
brings back the amplifier to normal operation at the same volume as in operation at the
point the mute function was activated.
VOLUME ADJUSTMENT
The level control may be adjusted manually using the front panel knob or by using the +
and - buttons on the remote control.
SELECTOR
The selector now selects one of five available inputs. Each step clockwise selects the next
input in sequence. Selection may also be made using the remote control by pressing the
key corresponding to the input on the remote control.

5 SOUND QUALITY OPTIMIZATION
WARM UP SONIC EFFECT
If the amplifier has been powered off for some time, the optimum
sound quality is only reached after some time. It may take 15
minutes for the amplifier to reach optimum operating temperature, as
the circuits have to warm up to around +55 degrees Celsius
(=131degrees Fahrenheit).
6 MAINTENANCE AND CLEANING
The Metis 5 amplifier usually requires no maintenance. Please contact
your Goldmund approved dealer if any maintenance should be required.
Always turn the power OFF before
cleaning your amplifier.
To clean the external metal of the amplifier, always use a clean, soft,
damp cloth. Dampen it with water or a mild detergent solution. Avoid
abrasive or harsh cleansers (e.g. products containing sodium carbonate).
The identification plates are plated with precious metal. Simply clean
them with a soft cloth, without any chemical solution.
