Every HRS Isolation Base model series can be set to either transfer and dissipate energy coming to and from the component or isolate the component from the supporting structure. Each HRS Isolation Base includes either our Broadband Isolation Feet (SF2 & SF3), our Extended Low Frequency Feet (LF2 & LF3), or our Bi-Directional Noise Reduction Feet. The selection of the footer type is made to optimize the performance of each component. You can also adjust or change the footer type on each isolation base at any time to keep your system at peak performance. Please consult your local sales representative or HRS to make final footer selection to optimize performance of your system.
SF2 / SF3: HRS Broadband Isolation Feet – Isolates components from below 20 Hz to above 40k Hz. Excellent starting point for tube amplifiers, tube pre-amplifiers, DAC’s, phono pre-amps, and many turntables. Select proper component range from chart below. For large amplifiers and turntables, please contact HRS for custom settings.
LF2 / LF3: HRS Low Frequency Feet – Isolates component from below 10 Hz to above 40k Hz. Use for non-suspended turntables and when subsonic content is present and presents a potential feedback issue with the system. Also used for custom applications where they provide sonic benefit. Custom setup required for each component.
G7: HRS Bi-Directional Noise Reduction Feet – Transfers and dissipates energy coming to and from the component. Used for solid-state power supplies, power conditioners, tape machines, vacuum pumps, solid-state amplifiers, and solid-state pre-amplifiers. These can also be used if you prefer to not deal with different load ranges or where the use of chassis noise reduction products is not desired or possible. The HRS G7 feet do not have any load limit and can be used for any component.
