PLACEMENT OF THE 1012 DAC PREAMPLIFIER
Your Boulder 1012 DAC Preamplifier is designed to reduce the
effects that external magnetic and radio fields (RF) have on its internal
circuitry. While placement is not critical, known magnetic fields should
be avoided. Line of sight from the listening position is necessary for the
remote control to function properly.
Because the preamplifier is heavy, a solid, stable surface should be
used. As it will generate some heat, there should be good air circulation
around it. In particular, make certain that the power supply heat sink
fins on the rear of the chassis are not blocked.
You may want to have some access to the rear panels for cable
changes.
