SOLIDTUBE

Tube Condenser Microphone

Description

The AKG Model Solidtube is a large diaphragm condenser microphone that benefits from the combination of modern solid-state technology and vacuum tube driven circuitry. The microphone, released in 1997, AKG’s Jubilee year, provides the characterisitc warmth and generous margin of overload expected from classic tube powered designs. Solid state electronics within the N-Solid power supply ensure quiet and reliable operation.

The Solidtube has a large double screened housing that reacts minimally with the capsule and provides shielding from RF interference. Frequency response remains relatively flat within the range of ±2 dB. The mid-range cut at approximately 2 kHz and presence rise above 10 kHz are signature characteristics of AKG large diaphragm condenser mics dating back to the classic C 12. They provide depth and clarity to any recording. Mid-band pattern rejection at 1800 is in excess of 20 dB.

The microphone is response tailored for solo vocal and instrumental pickup in the studio, and as such, has only a dedicated cardioid pattern. The Solidtube is shipped with all necessary cabling, an isolation shock mount, windscreen and a custom aluminum flight case.
