Variable-pattern vacuum-tube condenser microphone The HELIOS is a triumph of design. Like its sister, ORPHEUS, the HELIOS uses the same highly sensitive 1.07" dual-diaphragm capsule, but also employs the inherent warmth of valve circuitry. If you`re looking for a microphone that captures its subjects accurately, with a complete low-end response and a smooth, beautifully detailed high-end presence, then the HELIOS is for you. This precision allows you to transparently position your subject within a mix, without having to resort to heaps of EQ and dynamics processing to do the job for you. The SPS-1 power supply has a variable pattern control allowing a smooth transition from OMNI to Figure 8 pattern, and anything in-between. Allied to this are switches for a low-cut filter and -10dB pad, making the HELIOS one of the most flexible microphones available in any class. They`ve even added a TUBE READY light - in cool blue, of course - to let you know when you can start working.
