Boulder Amplifiers 1012 DAC Preamplifier - Manual (Page 30)

THEATER MODE
When the 1012 preamplifier is used in a surround sound theater
system, it is normally desired to bypass the volume control, thus letting
the surround processor control the volume.
WARNING: Setting an input to THEATER MODE forces the volume
to unity gain. Use only in conjunction with a surround processor.
Again pressing the same input source number will make “NORMAL
MODE” show in the bottom display row. Rotating the volume control
will show “THEATER MODE-Caution.”
