Delphos Condenser Microphone

The Delphos is available exclusively from our wonderful dealers.

The Delphos is a premium all-purpose studio condenser, featuring unhyped and natural frequency response, very high sensitivity, and very low self-noise.

The microphone uses a highly optimized transformerless circuit, which provides a pristine signal path. The microphone's circuit boards are manufactured and populated in the US, using the finest components sourced from around the world, including low-noise NOS transistors and imported European capacitors.

Two switches located on the front of the microphone provide pattern control (Cardioid/Omni) and pad (-10dB).

Each Delphos is assembled in California, manually "burned in," and extensively tested after manufacturing to ensure the best possible performance.

The microphone is painted in California with a 3-stage enamel finish. The color is dark blue metallic. The ROSWELL logo nameplate is embossed brass.

We have created a new shockmount for the Delphos. Its cut-away face allows the microphone to be easily positioned close to a singer or instrument without hardware standing in the way. This allows you to take advantage of the microphone's natural proximity effect.

The Delphos includes a screw-on elastic shockmount, a vinyl storage pouch, and a compact flight case.

Component Details

The transistors in the Delphos are all NOS parts, no longer made but ideal for this circuit. The JFET is selected for low input capacitance, then manually biased in our shop to maximize signal level without distortion.

Every resistor in both the audio and DC power circuits is a low-noise, high-precision metal film type. Special care was taken to select signal-path capacitors for the best sound.
