AMPLIFIER CONTROLS
The THA2 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.
BINAURAL MODE SWITCH
The Binaural stereophonic-to-binaural DSP implementation is designed to improve
headphone listening of standard stereo audio records.
This method will improve the fidelity of music reproduction and reduce the fatigue of the
listener.
For more information about this implementation, contact your official Goldmund
representative.
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 the digital input.
SERIAL PORT
The THA2 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).
Note:
Binaural records must be played
using the standard mode.
