2. Mark the guidelines for the opening on the wall or furniture.
• If the MP 101 will be installed in a wall box, place the box against the installation
surface and draw a line on it around the outside of the box.
• If the MP 101 will be installed without a wall box (using mud rings or fastening it
directly to the wall or furniture), measure and mark the surface for the cutout area
indicated in the template.
3. Cut out the material from the marked area.
4. Check the opening size by inserting the wall box (if used) or the MP 101 (if no box is
used) into the opening. The box and preamplifier should fit easily into the opening.
Enlarge or smooth the edges of the opening if needed.
