Thermionic Culture EarlyBird 2.2 Dual Channel Microphone Preamp (with EQ)

The Earlybird 2.2 contains 2 channels of very high quality valve pre -amplification. The circuit design utilises a 'push pull' 'class A' type of amplification in order to provide ultimately clean gain, giving the lowest noise and distortion figures possible in a mic pre-amplifier. The input and output transformers have been designed by working together with Sowter transformers to provide results that are optimised for this unit. This design work provides the Earlybird 2.2 with the lowest phase shift and highest headroom possible from a mic pre- amplifier. This version of the Earlybird pre-amp design also includes extra features such as 3 bands of active lift EQ with switchable mid range frequencies and high pass filters, and a function switch to help interface the unit in different usage scenarios. The essential mic-preamp settings such as gain, impedance, 48v power and phase are all catered for by the front panel controls.

Features:

• 2 Channels of extremely high quality push pull' 'class A' type of valve pre amplification
• 3 bands of active lift EQ with 2 mid range frequencies and switchable high pass filters
• Clean gain, giving extremely low noise and distortion figures
• Essential mic-preamp settings such as gain, impedance, 48v power and phase are all catered for by the front panel controls
• Can be optimised for use with a large variety of mics, signal levels and different uses whilst remaining in an equipment rack
• Function switch will allow the unit to take it's input from, mic. in, line, or the Pullet sockets
• Massive clean output, but can be trimmed by output level controls, some coloration can be obtained if desired
