Thermionic Culture Earlybird 2.2 话放

the earlybird 2.2 contains 2 channels of very high valvepre -amplification. the circuit design utilises a 'push pull''class a' type of amplification in order to provide ultimatelyclean gain, giving the lowest noise and distortion figures possiblein a mic pre-amplifier.
 
the input and output transformers have been designed by workingtogether with sowter transformers to provide results that areoptimised for this unit. this design work provides the earlybird2.2 with the lowest phase shift and highest headroom possible froma mic pre- amplifier.
 
this version of the earlybird pre-amp design also includes extrafeatures such as 3 bands of active lift eq with switchable midrange fre and high pass filters, and a function switch tohelp interface the unit in different usage scenarios.
 
the essential mic-preamp settings such as gain, impedance, 48vpower and phase are all catered for by the front panelcontrols.
 
the active eq uses the unique 'varislope' e for the 'bass'and 'top' lifting controls. the 'mid' lift control provides abroad, musical curve that can be centred at 800hz or 2.8khz byuency select switch. this curve interacts well with the top andbass controls to provide a wide degree of tone shapingpossibilities.
 
as the active eq works in the feedback part of the circuit,switching the active eq in does not, therefore introduce any extragain stages into the signal path. this means that the eq can beused without fear of introducing unwanted artefacts from extra gainstages.this perhaps makes recording a little easier when a subtleamount of eq can be added without fear of signal degradation.
 
the high pass filters are arranged so that the first two switchpositions provide 12db/octave filters to cut out unwanted lowfre at 40hz or 100hz. the last position provides a filterwith more of a shelving nature that can combine with the bass liftcontrol to give a simultaneous mid cut and bass lift ifdesired.
 
the function switch allows the unit to take it's input from eitherthe 'mic in' xlr sockets, the 'line in' sockets or the'pullet'sockets. so the unit can be connected for different uses whilstremaining in an e rack. the variable impedance and padsettings on the switch allow the input circuitry of the earlybird2.2 to be optimised for use with a large variety of mics and signallevels. they can also be used for creative tonal choices if sodesired.
 
we find that the variety of functions possible with the earlybird2.2 make it extremely versatile and coupled with the outstandingsonic results it is a great addition to any type of studio that isused to record or mix sound.
 
the pullet, is the perfect companion to the earlybird 2.2 tocomplete a superb mastering e
