INTRODUCTION
GOLDMUND TELOS 590 NextGen 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.

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 Telos 590 NextGen as well
as between the Telos 590 NextGen 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 Telos 590 NextGen is designed to provide.
In all typical cases Goldmund recommends using the special Goldmund Lineal interconnect
and digital cables.
1.2 UNPACKING
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.
WARNING
If you need to return the Telos 590 NEXTGEN
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 Telos 590 NEXTGEN in transit.

1.3 CHOICE OF THE TELOS 590 NEXTGEN 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 Telos 590 NextGen is isolated from vibrations of mechanical
components, including the player transport itself.
1.4 POWER SUPPLY
The Goldmund Telos 590 NextGen 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 Telos 590 NextGen 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.

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 Telos 590 NextGen, avoid any multi-way plugs or extension
cords.
Connect a computer, CD/DVD or Blu-ray player to the back panel of the Goldmund Telos
590 NextGen integrated amplifier, using either the USB Audio (input 1), Toslink Optical
connector (input 2), RCA Digital (input 3) or RCA Analog (inputs 4 to 8).
When the input source is connected, connect your Telos 590 NextGen using the two
speaker output connectors located on the rear plate of your unit.
Select one of the 8 available inputs for listening using the front input knob or the remote
Only one connection per input can be used at once.
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.
WARNING
For safety reasons connect all cable
between your sources and speaker
to your Telos 590 NextGen before
turning it on.
