Thermionic Culture EARLYBIRD-4 4 Channel Preamp with EQ

The 3RU 19" Earlybird 4 has a unique valve design, in that it uses Class A bias valves in a push-pull circuit. Thermionic Culture founder and chief designer Vic Keary believes that this is one of the finest pre-amplifiers available today, and despite their use for distortion in instrument amplifiers, valves have better distortion and lower noise than solid state amps. Dues to especially designed Sowter transformers the Earlybird 4 boasts well under 0.1% distortion. It has a very high output level of +32dB and if desired, 2nd order harmonics can be introduced by increasing mic gain and reducing output gain. The unit has switched gain controls with a maximum of 62dB of mic gain and a variable output along with pads, phase and stepped filter. A pair of meters can be switched between 1 & 2 and 3 & 4.
