Goldmund TELOS 390 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, 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.

The Telos 390 amplifier, as all high quality amplifiers generates a lot of heat when driven at
high levels and must therefore be vented properly. It is mandatory to allow proper cooling
of the heatsinks.
Do not put temperature sensitive equipment on top of the Amplifier.
L I N E V O LTA G E A D J U S T M E N T
A voltage selector is provided in the backplate of the Amplifier.
If your line voltage is not adapted to the voltage indictaed on the serial plate of the Amplifier,
please consult your local GOLDMUND dealer for adjustment.
AT T E N T I O N
On the 220V position, the preamplifier will function properly for main line voltage between
200 and 240V. At 110V the main line must deliver between 105V and 125V. If your main line
voltage operates outside these tolerances, please consult your Goldmund dealer.
Us a 5A delayed fuse for 220V and an 8A 110V operation.

Connect the powercord 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.
Connect the interconnects from any digital sources to line inputs 6 to 8.
ATTENTION
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.

POWER
The TELOS 390 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 blink
intermittantly.
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 eight available inputs (5 analog and three digital). 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.
OPENING VOLUME MEMORY
This function is only accessible via the remote control. It allows the volume to be
automatically set to the level fixed when the unit is turned ON.
To adjust the level, first select the desired output level, then press MEMO on the remote
control.
If at any time during playback you wish to retun to this level, just press the RESETbutton.

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 tempearture, as the circuits have to warm up to around +55 degrees Celius (=131
degrees Farenheit).
M A I N T E N A N C E & C L E A N I N G
The Telos 390 amplifier usually requires no maintenance. Please contact your Goldmund
approved dealer if any maintenance should be required.
Always turn the power OFFbefore cleaning your amplifier.
To clean the external metal of the Amplifier, always use a clean, soft, damp cloth. Dampen
with water or a mild detergent solution. Avoid abrasive or harsh cleansers (eg. products con-
taining sodium carbonate).
The identification plates are plated with precious metal. Simply clean them with a soft cloth,
without any chemical solution.
