INTRODUCTION
FRONT PANEL DESCRIPTION
General
Thank you for purchasing a D.A.S. power amplifier. It has been built with the most advanced modular
technology, and has been designed through the use of computer-aided design for both the electronic and
mechanical parts.
5
Level controls (C)
Use to set the output level of each channel. The maximum gain is achieved when the
LEVEL rotary potentiometer is turned fully clockwise.
Clip LED (D)
When the output signal distortion of the corresponding channel exceeds 1%, the LED will
light, due to the signal level being is too high.
Protection LED (E)
When circuit protection works, the LED will light, especially when the heat-sinks overheat
or detect the DC voltage in the amplifier. Also, turn on the amplifier and within three seconds,
the amplifier is ready to work, the LED will shine. When startup is complete or the problem is
removed, the LED will extinguish, and resume working normally.

Signal LED (F)
When there is an input signal, the LED will light. If not, please check the gain
settings. If necessary, the gain can be increased. Check the input connection and signal
audio source. If the Clip LED shines a little or shows no signal, check the output wire
whether it is in short-circuit or not.
Cooling air grilles (G)
Fan cooling permits airflow through the most vital parts of the amplifier. Since the airflow
finds its way out through these grilles, keep them as clean and dust-free as possible to assure
proper cooling.
