Rogue Audio RA-1 Stereo Solid State Power Amplifier

Reference-Quality Solid State Power

The Rogue Audio RA-1 is a solid state stereo power amplifier from Rogue Audio of Brodheadsville, Pennsylvania, following the success of Rogue's hybrid Class D integrated and power amps. Rogue built it to lower the entry point for a reference-quality, full-featured power amplifier.

It delivers 175 watts per channel into 8 ohms and 275 watts into 4 ohms from a compact 3/4-size chassis. Because there are no tubes, there is no biasing and no regular maintenance. It comes in Black or Silver.

Hypex UcD Modules and a Massive Linear Power Supply

Rogue has more than a decade of experience with Class D amplifiers. The RA-1 pairs Hypex UcD output modules with a massive linear power supply, built on a heavy 2-ounce copper circuit board with precision components.

Stereo or Bridged Mono

A switch on the back sets the RA-1 for normal stereo or bridged mono. Use two RA-1s as a pair of monoblocks, or bridge a single RA-1 to power a center channel.

Built for Everyday Use

Standby circuitry keeps the amplifier ready and cuts warm-up time. A 12V trigger input lets your preamp turn it on and off, and short circuit protection guards against speaker wiring faults. Every RA-1 is fully tested, burned in and auditioned, and it carries a 3-year limited warranty from Rogue Audio.

How the RA-1 Fits Your System

The RA-1 is a power amplifier, so it needs a preamplifier, or a source with volume control, to drive it. Connect using either the balanced XLR or the RCA inputs; a switch next to the inputs picks which pair is active.

It has no volume control, source selection or phono stage of its own.

Who Is This Amplifier Best For?

• Listeners with a separate preamp — XLR and RCA inputs work with balanced or single-ended preamps.
• Anyone who wants low-maintenance power — No tubes to bias or replace.
• Systems that may grow — Add a second RA-1 later and bridge both as monoblocks.
• Home theater owners — Bridge one RA-1 to power a center channel.
• Not for — Anyone without a preamplifier, since the RA-1 has no volume control.

How Does It Connect to Your System?

• Preamp: Connect XLR or RCA cables from your preamp, then set the input switch to match.
• Speakers: Connect your speaker cables to the gold-plated binding posts.
• Bridged mono: Flip the Bridged/Stereo switch and use the left channel input.
• Trigger: Optionally, connect your preamp's 12V trigger to the 3.5mm trigger jack.
• Available in Black and Silver.

Frequently Asked Questions

Does the RA-1 use tubes?

No. The RA-1 is fully solid state, using Hypex UcD modules. There are no tubes to bias or replace.

Can I use two RA-1s as monoblocks?

Yes. Set each amplifier's rear switch to Bridged and use the left channel input. A single bridged RA-1 can also power a center channel.

Can I connect it straight to a streamer or CD player?

Only if that source has its own volume control. The RA-1 has no volume control, so it is normally used with a preamplifier.

What is the warranty?

Rogue Audio gives the original purchaser a 3-year limited warranty on parts against defects in material and workmanship when bought from an authorized Rogue Audio dealer in the United States.
