A Premium Multi-Pattern Studio Condenser with Natural Tone, Ultra-Low Noise & True Recording Versatility
The Roswell Pro Audio Delphos II is a flagship studio condenser microphone designed for engineers and creators who demand uncompromising clarity, exceptional sensitivity, and whisper-quiet performance. With three polar patterns—True Cardioid, Omni, and Figure-8—plus a switchable 10 dB pad, it delivers the flexibility needed for vocals, acoustic instruments, voiceover, and detailed studio work of all kinds.
“The Delphos always makes it to my final round of favorite vocal mics. It has won many unexpected blind comparisons. It’s a desert island mic for sure.”
— Tommy Torres, multiple Latin Grammy–winning artist/producer
Built to Outperform Mics Three Times the Price
The Delphos II expands on the legacy of the original Delphos—known for outperforming microphones far above its price bracket. Its highly optimized transformerless circuit provides a pristine, transparent signal path, while US-made circuit boards and globally sourced premium components ensure top-tier accuracy and reliability.
Key upgrades include low-noise NOS transistors, custom US-made signal capacitors, upgraded DC circuitry, and a hand-tuned capsule that captures detail with remarkable naturalness.
True Cardioid Mode for Maximum Sensitivity
Front-panel switches allow quick and intuitive control of polar patterns and pad settings.
-
True Cardioid Mode: Removes the rear diaphragm from the circuit, increasing sensitivity and improving the signal-to-noise ratio.
-
Omni Mode: Naturally reduces proximity effect.
-
Figure-8 Mode: Ideal for side-by-side vocals, acoustic duets, mid/side recording, and room capture.
-
10 dB Pad: Provides headroom for high-SPL sources.
Hand-Built, Tuned & Tested in California
Every Delphos II undergoes Roswell’s full burn-in process, followed by extensive acoustic, electrical, and listening tests. The result is tightly controlled performance consistency and a microphone that sounds phenomenal straight out of the case.
The microphone features a multi-stage metallic enamel finish in dark blue with an embossed brass Roswell badge—striking, durable, and studio-ready.
