Black Lion PG-2R: Regulated, Clean Power for the Studio Rack

The Black Lion Audio PG-2R is a 2U rackmount power regulator and conditioner, holding its output at 120 volts within a tight plus-or-minus 2-volt window. It does everything a conditioner does and then actively corrects the voltage feeding the rack. Twelve switched, filtered outlets on the rear serve permanent gear, while two front convenience outlets stay open for chargers and tools. In two rack spaces it delivers power that is both clean and steady.

Regulation Versus Conditioning

A conditioner filters noise and blocks surges, but it passes along whatever voltage the wall provides, sags and all. A regulator adds an active stage that raises low voltage and trims high voltage back toward a target. The PG-2R combines both, locking its output near 120 volts even when the incoming line drifts. That stability matters for gear that sounds or performs differently as its supply voltage wanders.

Why Steady Voltage Matters

Undervoltage, or a brownout, can make amplifiers strain and digital gear behave unpredictably, while overvoltage stresses power supplies. By holding a plus-or-minus 2-volt window, the PG-2R keeps connected equipment inside its designed operating range. Studios on old wiring or busy circuits see the biggest benefit, since their line voltage swings the most. Consistent voltage means consistent performance session after session.

Noise Filtering and Surge Protection Built In

The PG-2R filters 99.7 percent of line noise, the EMI and RFI, electrical and radio interference, that adds hiss and buzz to audio. It also carries a 2775-joule surge absorption rating, a measure of how much spike energy it can soak up before it stops protecting your gear. Together these stages shield converters, preamps, and monitors from both everyday grime and sudden transients. The regulation sits on top of that protection rather than replacing it.

Fourteen Outlets and Front-Panel Control

Twelve switched, filtered, surge-protected outlets on the rear split into banks for digital audio, analog audio, and high-current devices. Two convenience outlets on the front handle quick tasks, and dual USB ports charge phones or small devices without a wall outlet. A real-time voltage meter reports the regulated output so you can confirm the line is stable at a glance. LED indicators and an audible siren warn of grounding faults, polarity issues, and unsafe voltage.

Separated Banks Keep Digital and Analog Apart

Grouping the rear outlets by device type is more than tidy cable management. Keeping digital gear on its own filtered bank stops converter and clock noise from leaking into quiet analog equipment. A dedicated high-current bank serves amplifiers and monitors that draw heavier loads. That organization helps the whole rack stay quiet even as it grows.

Where the Black Lion PG-2R Fits

Studios with unstable or overloaded power reach for the PG-2R to tame a line that will not hold 120 volts. Live and touring rigs use it to keep voltage steady across unfamiliar venue power. Because it regulates, filters, and protects in one 2U chassis, it replaces a separate conditioner and voltage stabilizer. It suits any room where steady, clean power is worth protecting a full rack of gear.
