Installation & Placement
Lab12 pre1 should be placed on a solid flat surface. You should avoid placing it near a heat source as
this could compromise the performance and reliability. You should never place another component
directly on top of this device.
Make sure that your pre1 has an adequate flow of air around it. Pre1 could be warm in some points;
this is normal and w
ithin parts’ specifications.
Take care of the front panel’s glass blasting anodized finishing using a soft dry cloth. No n
eed to use any
sprays or polishes. Never use cleaners containing abrasives, as this will damage the surface.
