The Earlybird 2.2 contains 2 channels of very high quality valve pre-amplification. The circuit design utilizes 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 optimized 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.
The active EQ uses the unique 'varislope' EQ curves for the 'bass' and 'top' lifting controls. The 'mid' lift control provides a broad, musical curve that can be centered at 800Hz or 2.8KHz by the frequency select switch. This curve interacts well with the top and bass controls to provide a wide degree of tone shaping possibilities.
As the active EQ works in the feedback part of the circuit, switching the active EQ in does not, therefore introduce any extra gain stages into the signal path. This means that the EQ can be used without fear of introducing unwanted artefacts from extra gain stages. This perhaps makes recording a little easier when a subtle amount of EQ can be added without fear of signal degradation.
The high pass filters are arranged so that the first two switch positions provide 12dB/octave filters to cut out unwanted low frequencies at 40Hz or 100Hz. The last position provides a filter with more of a shelving nature that can combine with the bass lift control to give a simultaneous mid cut and bass lift if desired.
The Function switch allows the unit to take its input from either the 'mic in' XLR sockets, the 'Line in' sockets or the 'Pullet' sockets. So the unit can be connected for different uses while remaining in an equipment rack. The variable impedance and pad settings on the switch allow the input circuitry of the Earlybird 2.2 to be optimized for use with a large variety of mics and signal levels. They can also be used for creative tonal choices if so desired.
We find that the variety of functions possible with the Earlybird 2.2 make it extremely versatile and coupled with the outstanding sonic results it is a great addition to any type of studio that is used to record or mix sound.
The Pullet, is the perfect companion to the Earlybird 2.2 to complete a superb mastering equaliser.
