AMPLIFIER CONTROLS
The Telos Headphone 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 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.
VOLUME ADJUSTMENT
The level control may be adjusted manually using the front panel knob.
SELECTOR
The selector knob selects one of three available inputs (1xUSB, 2xDigital in parallel and
1xAnalog).
An orange locking led is lighted up when an analog or USB input is selected and when a
digital source is connected to one of the digital input.
SERIAL PORT
The Telos Headphone Amplifier can be controlled via a standard computer serial port,
which is used also for future software upgrade, please contact your Goldmund
representative for more details.

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).
