The Thermionic Culture Rooster 2 is a 2-channel all-valve preamp with EQ and distortion controls. It is designed for a wide range of applications and can produce a large range of tones, harmonic distortion and subtle dynamic control.

The preamp section can be used to add gain to mic, line or DI input signals. The double triode input valve (12AX7) provides a smooth sounding gain stage after the balancing input transformer.

48 volts can be applied to phantom powered mics by using the special toggle switch. The DI input bypasses the transformer to give a suitable high impedance unbalanced input.

The 'Attitude' section provides control over the amount of distortion inherently produced by the 5654 valve.

The natural distortion figure for the Rooster 2 is well below 0.1% at low Attitude settings. As the Attitude is increased, extra harmonics, mostly musical, will be added to give a warm 'valvey' sound.

Similarly to the Culture Vulture, the unit will tend to produce predominantly more 2nd order harmonics when in 'Triode' mode and 3rd order harmonics when in 'Pentode' mode. This provides a creative means of both tone and dynamics control over the input signal as well as allowing the user to select how much and what kind of harmonics are present in the signal.

The EQ section provides a simple yet powerful musical control over frequency content.

The Bass lift control gives a continuous control over the amount of bass using a unique ' varislope' curve which peaks at 60Hz.

The 'mid/high' lift control gives a bell type curve with variable gain peaking at either 2.5KHz / 4KHz or a 'varislope' curve peaking at 12KHz, all selected by the frequency select switch.
