A rack power conditioner is a 19" rack-mountable unit that distributes filtered, surge-protected AC power to every device installed in a rack. Furman's rack conditioners install into a single rack space (1U-3U depending on model) and typically provide 6-10 switched outlets on the rear panel.
This category includes four Furman series, ranked by protection level:
- Merit / Merit Z — standard-level surge protection and RFI/EMI filtration, 9-10 outlets, ideal for home studios and instrument rigs on a budget.
- Classic — advanced Series Multi-Stage Protection (SMP) and Linear Filtering Technology (LiFT), built for touring musicians and mobile engineers facing inconsistent venue power.
- Prestige — Extreme Voltage Shutdown and premium filtration for professional studios where signal purity is critical.
- Contractor — adds power sequencing and remote monitoring (BlueBOLT-compatible on select models) for fixed installations and venues.
Frequently Asked Questions
How much rack space does a power conditioner take up?
Most Furman rack power conditioners occupy 1U (one rack space); some Prestige and Contractor models with additional outlets or sequencing features occupy 2U-3U.
What is Series Multi-Stage Protection (SMP)?
SMP is Furman's proprietary surge suppression technology, used across the Classic, Prestige, and Contractor series, that clamps voltage spikes at multiple stages to extend the working life of the protection circuit compared to single-stage designs.
Can a rack power conditioner power my whole rig?
Yes, as long as the combined amperage draw of your connected gear stays under the unit's rated capacity — typically 10A, 15A, or 20A depending on the model. Check each device's power draw before connecting it.
