Thermionic Culture The Rooster Dual Mono Mic / Line / DI Pre-Amp

The Rooster Dual Mono Mic / Line / DI Pre-Amp description:

The Thermionic Culture Rooster is a twin channel valve based mic/line + DI pre-amp with EQ, featuring a distortion section based around the same 5725 used in the popular Culture Vulture.

The input stage of the Thermionic Culture Rooster uses a custom 1200-ohm input Sowter transformer and an ECC81/12AT7 valve. The EQ section has a broad bass lift control, peaking at 60Hz, a mid cut at 700Hz, and a selectable mid/high lift at 2.5k, 4k ("bell" shaped) and 7k (shelving) respectively. The 6 position bass cut is straight off the Earlybird 2 pre-amp.

The Thermionic Culture Rooster features the 5725-distortion tube, offering a subtle distortion characteristic in the triode position, more so than a Culture Vulture due to the higher HT voltage. It has a very low (about 0.01%) distortion when the Feedback control is set to Max. In the pentode mode it generates more 3rd harmonic distortion. Distortion can be pretty radical when feed back is "off" and the input is high. The output valve is ECF80 which combines high output with low impedance (less than 100 ohms). The Thermionic Culture Rooster also features +48v phantom power, and phase reverse.
