The FLAIR circuitry enhances a signal's presence and cutting ability.

The correlation between frequency- and amplitude-time- base to the dynamics of the input signal remains intact.

Ideally suited for HD recording.

Sound optimization already during recording: FLAIR circuitry

The FLAIR circuitry enhances the presence of vocals and acoustic instruments, FLAIR makes these elements cut better through a mix. It has proved to be superior in double-blind tests. Once a signal completes the semi-conductor amplification stage, it is then split and fed into the tube stage and the FLAIR electronics.

The FLAIR circuit is built from a unique valve/inductor/capacitor hybrid. It operates in a bandpassed frequency range from 1.5 kHz to 20 kHz. The center frequency is set at 6 kHz with a boost of 2.5 dB. Frequency response, harmonic contents and time of impact are manipulated as well. The FLAIR circuit's output is mixed directly in the tube with the source signal. The circuit's character can be best described as a "closed shelving bandpass"; neverthe- less, a shifted timebase (phase) is responsible for boosting the harmonic content. The close correlation, however, between frequency- and amplitude-timebase to the dynamics of the input signal remains intact.

When working on a hard disc recording system, you will greatly appreciate the appeal of the Flair circuitry and the topnotch sounding signal it delivers. It can spare you hours of twiddling with a compromised recording.

WARM UP circuit

The WARM UP circuit measures the tube's anode plate and heater voltages. After approximately eight seconds the anode voltage of 250 Volts is reached; the heater voltage takes only four seconds. Once the ideal working status is achieved, the output signal is enabled. As the WARM UP LED is lit, no output is present.
