Installation Guide Installation Guide for ClearSonic AmpPac
  1. Will putting a shield in front of the amplifier fix our problems?
  2. Usually not by itself. If you do not have acoustically absorbent treatments to the sides and behind your amplifier, you may end up with a very roomy sound in the audience areas. We strongly recommend the use of sound absorbing panels on the lower half of the ClearSonic Panels as well as panels behind and beside your amplifier to soak up all that excess acoustic energy. AmpPacs with list and Sorber panels provide the best sound reduction.

  3. What are the shield panels made of?
  4. The standard ClearSonic Panel systems are made of 1/4-inch thick American made acrylic sheet, similar to Plexiglas™.

  5. Will the hinges hold up?
  6. The full-length heavy-duty plastic hinges have been improved several times since 1995 and hold up very well. The latest design incorporates a “tooth” that snaps into a groove along the long edge of each panel, ensuring that the panels will not come apart. This unique hinge also allows our systems to fold “accordion style” for easy transport. The flexible part of ClearSonic hinge is at least 0.06″ thick, almost twice the thickness of our competitor’s catalog bought hinge. We own the die for our heavy-duty extruded hinge. No one else has it. Don’t settle for some flimsy, off-the-shelf hinge from a competitor that may be only 0.038″ inches thick or less at the flexible part that will split and fail in short order.

  7. Do I need to add more acrylic sections if the volume is still too loud?
  8. Many people ask if more panels will help, and sometimes it will, although sometimes less acrylic and more acoustic panel treatment is necessary. Adding more acrylic will reflect more direct energy, but that energy still needs go somewhere. Don’t just trade a loud direct amplifier sound for a loud roomy sound! Sound absorbing panels greatly improve the effectiveness of acrylic shields by soaking up much of the direct and reflected sound coming off the amplifier and shields.

  9. Is your amplifier shield factory-assembled and packaged well enough to take the abuse of shipment?
  10. ClearSonic Panels ship in a heavy-duty box that includes extra packing materials. Once again, it costs us more to do this, but we feel that drum shields won’t do you much good if they arrive broken. If your shipment appears to be damaged on arrival, be sure to note the damage with the carrier and contact us immediately.

  11. What is the return policy?
  12. ClearSonic Panels are shipped with the paper masking on the surface of the acrylic to prevent scratches during transit. Returns are not accepted if the paper masking has been removed. Returns may be considered if the product is unused and in its original packaging. Returns will be handled on a case per case basis and are subject to restocking fees and return shipping costs. Original shipping costs are non-refundable.

The ClearSonic AmpPac 21 amplifier isolation shield creates an enclosure for a small combo amp or speaker cabinet with an open back and comes with a lid. Use these amp shields to control volume on stage or in the studio. This will provide better separation between instruments for recording and live sound applications.

An six section ClearSonic panel and SORBER baffles completely surround the amp and the S3D provides a cap.

ClearSonic products are pre-assembled, portable, and less expensive than a DIY speaker enclosure.

Here, the SORBER baffles have been attached to the inside of the 6-panel clear shield. Each section of the A1824X6 is 18″W x 24″H. This combination blocks sound and absorbs reflected energy before it can escape into the room. This set-up is identical to the AmpPac 20, with the addition of an S3D as a lid section on top to further reduce sound transmission. Approximate sound reduction of 50%.
