Dawner Prince Electronics has officially announced the release of the Eclipsa Triple Rotary, a groundbreaking modulation pedal that meticulously recreates the legendary Yamaha RA-200 rotary speaker system. Moving beyond standard Leslie-style emulations, the Eclipsa captures the unique “triple-rotor” architecture that defined the lush, swirling textures of 1970s progressive rock.
The Return of the Triple Rotor
While traditional rotary cabinets rely on a single drum and horn, the original Yamaha RA-200 utilized three independently driven rotating drivers paired with static speakers. This complex configuration created a dynamically evolving spatial character that was famously championed by guitarists like David Gilmour.
The Eclipsa utilizes advanced DSP modeling to recreate this behavior. It doesn’t just mimic the frequency response; it captures the intricate phase relationships and movement of all three rotors spinning in unison.

Analog Warmth: The Alembic F-2B Preamp
To complement the digital precision of the rotary effect, Dawner Prince has integrated an analog solid-state version of the Alembic® F-2B tube preamp. Known for its articulate clarity and musical warmth, this preamp section allows users to drive the signal into natural saturation, perfectly mirroring the “front-end” grit of the classic rigs.
Modern Performance Features
Despite its vintage inspiration, the Eclipsa is built for the modern stage and studio. It features:
-
Full MIDI Integration: Control every parameter via CC or recall up to 127 presets.
-
Three Virtual Microphones: The stereo output is derived from a sophisticated virtual mic placement, providing a deep, immersive stereo field.
-
Magnetic Contactless Bypass: A proprietary switching system ensures silent, reliable operation without the mechanical wear of traditional switches.
-
Dynamic Control: Adjustable Inertia (acceleration/deceleration) and Distance (mic placement) allow for total customization of the “air” around the cabinet.

Detailed Features & Specifications
-
Rotary Controls: Slow Speed, Fast Speed, Inertia, and Distance.
-
Tone Shaping: 3-band EQ (Bass, Middle, Treble) based on the F-2B, plus a Bright switch.
-
The “Blend” Knob: Mix the triple rotary signal with a static 4×12″ speaker simulation for added punch and focus.
-
I/O: Stereo outputs, Expression pedal input, and MIDI In/Thru.
-
Input Flexibility: A dedicated Instrument/Line switch makes it compatible with guitars, synths, and studio outboard gear.

FAQ: Everything You Need to Know
Q: How does the Eclipsa differ from a Leslie emulator?
A: Most Leslie pedals emulate a single woofer and tweeter. The Eclipsa emulates three separate rotating speakers plus static drivers, resulting in a much more complex and “thick” modulation.
Q: Can I use it with a synthesizer?
A: Yes. The onboard Instrument/Line switch adjusts the input gain stage to handle high-output signals from synths or studio mixers without unwanted clipping.
Q: Does it require a high-current power supply?
A: Surprisingly, no. The Eclipsa is highly efficient, drawing only ~140 mA at 9V DC, making it compatible with most standard pedalboard power supplies.
Q: Can I use an expression pedal to change speeds?
A: Absolutely. The “EXT IN” port allows for continuous speed control, mimicking the feel of a real rotary speed remote.

The Verdict: Who is this for?
The Dawner Prince Eclipsa is a niche but necessary tool for tone purists. It fills a massive gap in the market for those seeking the specific “Pink Floyd” RA-200 sound without hauling a 200lb cabinet.
With its combination of an analog Alembic-style preamp and high-end DSP, it offers a level of “hi-fi” rotary modulation that feels expensive and cinematic. The addition of 127 MIDI presets and a compact, CNC-machined enclosure makes it as practical as it is sonically impressive.
