HELIX
Introduction
Thank you for purchasing the Harmonic Resolution Systems Helix. When used properly, they will give you many years of superior
musical or video signal reproduction. The HRS Helix is designed to significantly reduce the negative impact of air and structure-
borne vibration on your audio or video component performance. The Helix is specifically designed for use with components that
have stiffer (plate and billet) metal chassis construction and yields targeted performance improvements when used in conjunction
with the HRS Isolation Bases. The HRS Helix was designed specifically for use with HRS Isolation Bases. Using the HRS Helix in
conjunction with another shelf that does not have the same capabilities as the HRS Isolation Bases can limit the performance
benefits achieved by the Helix. The Helix can also be used in combination with HRS Damping Plates. While the Helix significantly
reduces bottom chassis noise, the Damping Plates will work to reduce top chassis noise in the component.
Safety Instructions
IMPORTANT!
Do not place the Helix over ventilation holes of any electronic component. The ventilation holes will be blocked and the internal
operating temperature of the component may be increased.
Setup Instructions
Before setting up your HRS Helix, remove the adhesive strip holding the adjustable screw in place on each assembly. This will
allow height adjustment to achieve equal pressure against the component between all Helix units. Then, the HRS Helix should be
placed directly on the HRS Isolation Base supporting your component. The HRS Helix is designed so that sets of three or four units
arranged as shown in the diagrams below will provide exceptional performance on any standard size component. If a component’s
base is over 350 square inches in area, adding a fifth Helix can significantly improve performance. Set the bottom chassis of the
component in direct contact with the rubber couplers on top of the HRS Helix. The adjustable screw insert of the Helix should be in
direct contact with the HRS Isolation Base surface. Proper setup and contact with the chassis will control bottom panel resonance
and transfer energy from the chassis into the Helix energy dissipation system. Refer to the diagrams below for recommended initial
Helix locations, then move each Helix in small increments and perform listening tests to find the optimal setup for your
components. If there is a drive, motor, or other noise source inside the unit, moving the closest Helix directly under the noise source
will often improve performance.

When setting up your Helix, HRS recommends beginning with the height of all Helix set as they were shipped from HRS (5

rotations of thread engagement) and placing the component so it rests on all of them. Push against the outside diameter of each
Helix and observe the resistance to movement relative to the chassis. If the resistance to motion differs, alter the height of one unit
at a time to achieve equal pressure at all locations. To adjust the Helix, insert the

from removing the screw). The photos below show units upside-down to best illustrate the full range of adjustment.
