GOLDMUND TELOS 1000 NextGen Universal Power 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, home -
networking and music distribution.
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 PREL M NAR ES
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 analog
pre-amplifier or acoustic processor such as the Mimesis 22H or Mimesis 32.5 with analog
or digital input.
The connection between the analog and digital sources and the acoustic processor as well
as between the pre-amplifier 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.
1.2 UNPACK NG
You will find in the GOLDMUND TELOS 1000 NextGen box:

WARN NG
If you need to return the TELOS 1000
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 1000 NEXTGEN in
transit. Use of alternative packaging is likely to

1.3 AMPL F ER LOCAT ON & COOL NG
The GOLDMUND TELOS 1000 NextGen amplifier, as all high quality amplifiers generates
a significant amount of heat when driven at high levels and must be vented properly. It is
mandatory to allow a proper cooling of the heat sinks. Do not put temperature sensitive
equipment on top of the amplifier.
Due to its weight, and to maximize the effect of the built-in "Mechanical Grounding"
construction, the TELOS 1000 NextGen is better located on the floor. Other very strong
supports can be used if they offer rigid transmission to the floor.
The TELOS 1000 NextGen is built on four very hard conical feet to ensure proper vibration
transmission to the amplifier support. This evacuates all detrimental vibrations inside the
amplifier, following the famous GOLDMUND "Mechanical Grounding" principle.
If you use more than one TELOS 1000 NextGen at any location, you may decide to stack
them. Be careful that the conical feet of the top amp are inserted properly on the top of the
steel bars of the amplifier located below. You may stack up to 3 amps provided extra care
is taken to ensure proper air circulation vents the rear heat-sinks.
Depending on the flatness of the surface where the amplifier will be located, you will adjust
the four round flat feet of the amplifier to allow full contact of the points with the support.

1.4 L NE VOLTAGE ADJUSTMENTS
A voltage selector is provided inside the amplifier.
If your line voltage is not adapted to the voltage indicated on the serial plate of the
amplifier, please consult your local GOLDMUND dealer for internal adjustment.
ATTENT ON
On the 220V position, the GOLDMUND TELOS 1000 NextGen amplifier will function
properly for main line voltage between 211V and 257V. On the 110V position, the main line
must deliver between 105 and 129V. If your main line is usually out of these tolerances,
please consult your GOLDMUND dealer.
Please check the value of the main line fuse. This fuse is located on the back panel of the
amplifier, above the two power cord receptacles.
Use a 4A delayed fuse for 220V area and 8A delayed fuse for 110V area.

2 CONNECT ONS
Connect the power cord to the back of the amplifier and plug it into the nearest wall plug.
Use only a 3 lugs grounded plug, for safety reasons. To get the best sound from the
amplifier, avoid any multiple plug or extension cord.
If used with an analog signal, connect the interconnect between the preamp and each
power amp and set the TELOS 1000 NextGen in analog mode. You may either use the
RCA female socket or the XLR. The XLR socket, especially useful in professional
installations, is wired as follows:
1. Grounding, Shielding
2. Hot
3. Cold
ATTENT ON
If you want to use a symmetrical 4 wire cable, never maintain the ground/earth
switch to "Float" or you may damage your amplifier.
When used with a digital input signal, connect the digital input cable to the digital input and
switch the amplifier into the digital mode. Since a digital Spdif cable carries 2 channels you
may link the digital output to the next amplifier to transfer the second channel.
Connect the speaker cable to one of the red and black terminals in the back of the
amplifier, or, if you use a Goldmund High Definition speaker cable, you can connect directly
from the speaker cable to one of the coaxial plugs on the back panel of the amplifier,
bypassing the amplifier adapter module of the speaker cable.
The 2 separate outputs (both 5 way post and coaxial) are connected internally in parallel.
They are provided to facilitate the connection in bi-wiring systems.
You may notice that the ground of the input plug and the black speaker terminal are the
same polarity. The amplifier is non-inverting in phase.

3.1 MANUAL OPERAT ON
On the front plate of the GOLDMUND TELOS 1000 NextGen amplifier you will find only two
POWER keys.
The two POWER keys have to be activated simultaneously to power the amplifier on.
This security feature is provided to avoid accidental POWER ON or POWER OFF.
As soon as the amplifier is connected to mains power, the orange indicator on the front
panel will blink briefly every 3 seconds.
Push both buttons of the front panel simultaneously in order to turn on the amplifier.
As soon as the amplifier is fully powered the green indicator will light steadily and the menu
will be displayed.
If the digital input is not used, the orange led is off, showing there is no lock and the
amplifier remains muted until a lock is found. The led will turn on as soon as the TELOS
1000 NextGen receives a digital input.
In analog mode (XLR & RCA) the orange led is always on.
By pressing the right key once, the amplifier is put in Operate mode “Unmute”, by pressing
the right key once again, the amplifier returns to the menu “Muted” state.
The amp may be POWERED OFF by pressing the two POWER keys simultaneously at
anytime.

WARM-UP SON C EFFECT
When the amplifier has not been used recently it will take 10 to 15 minutes for the amplifier
to reached optimum operating temperature.
SPEAKER POLAR TY
Even if you have a phase inverter on your preamplifier and have carefully selected the
proper line phase (see next paragraph below), there is a possibility to further increase the
sonic quality of your speakers by reverting the polarity of the speaker cable amplifier
termination. Line phase and speaker polarity interfere with each other however. We
therefore advise careful experimentation with all the combinations in order to arrive at the
best solution for your installation.
If your preamplifier has an absolute phase inverter, this will interfere too. If it has not, don't
forget the result will depend on the source, as most records and CDs have been recorded
without care for the absolute phase. Be patient…
MA N L NE PHASE NVERS ON
To select the proper phase, you have to select, by trying, one of the two power cord
positions.
We recommend that you proceed carefully when trying this. You must do it in combination
with the speaker polarity and/or with absolute phase switching to be sure of the result.

THE GOLDMUND EXCLUS VE "MECHAN CAL GROUND NG”
In the GOLDMUND TELOS 1000 NextGen amplifier, GOLDMUND has, as in other of its
Ultimate Line components, fully implemented an optimized vibration evacuation path. This
is called by GOLDMUND: "Mechanical Grounding". The perfect adjustment of this
evacuation provides the Telos 1000 NextGen with an extraordinary dynamic capability and
transparency, especially on low efficiency speakers.
To get all the benefits of this design, the TELOS 1000 NextGen must be located on a very
rigid support, or better directly on the floor, to be directly coupled with the building’s rigid
construction. Try various locations until you find the most rigid one. Avoid any decoupling
material, carpet especially, even between the furniture and the floor. Use the four pin-point
feet to couple the amplifier to the supporting furniture or to the floor.
With a very top system, the sonic improvement when the proper grounding is found is
obvious and worth the effort.
5 MA NTENANCE
The GOLDMUND TELOS 1000 NextGen amplifier usually requires no maintenance.
Always turn the power OFF before cleaning your amplifier. Use a clean, soft, damp cloth to
clean the amplifier surface. Dampen the cloth with water or a mild detergent solution.
Avoid abrasive or harsh cleansers (eg. products containing sodium carbonate).
