POWERING UP
With all your connections made, you are ready to listen to your
Boulder 1012 DAC Preamplifier.
The power LED will cycle through a variety of colors indicating a
standby mode. Power is applied only to the microprocessor during this
mode.
Press the POWER button to turn on the 1012. The indicator will
change to amber and power will be applied to the analog audio section.
If a digital input was previously selected, power will also be applied to
the DSP, D/A Converter, and analog low-pass filter sections which are
used only for digital signals.
During the power up sequence, the displays at left will be briefly
shown.
The front panel POWER button should be used for everyday turn
on and off. This switch mutes the audio, turns off all sections except the
microprocessor, and puts the preamplifier in a standby mode.
