Thermionic Culture Earlybird 4通道话放

the earlybird 4 contains 4 channels of extremely high pre-amplification. originally made in black in 1999, this isa special “revival” limited edition in red (limited to 49 only).the black edition is still available with the updatedcircuitry..
 
as the individual channel circuitry in this version of theearlybird has been simplified in order to provide 4 channels in one19” unit, so the individual channel specifications have risen. thusmaking this the most natural sounding, high version of theearlybird preamp to date.
 
effectively giving the user the cleanest possible valve gain with arange from 3db to 62db and a switchable input impedance to help inmatching the unit with different microphones.
 
this is one of thermionic culture’s all handwired products withpoint to point wiring throughout.
 
the circuit design utilises a ‘push pull’ ‘class a’ type of valveamplification in order to provide ultimately clean gain, giving thelowest noise and distortion figures possible in a microphoneamplifier.
 
the input and output transformers have received special attentionand by working together with sowter transformers, designs have beencreated that bring better results than ever before. the lowestphase shift and highest headroom are both benefits brought by thesedesigns.
 
it’s unusual to hear a mic amp with the earlybird 4’s andafter years of improvements vic keary proudly declares this “thebest, most real mic. amp ever ”. we hope that on hearing the unit’sbeautiful results yourself, you will agree with vic.
 
the pair of vu meters show the signal levels for 2 selectablechannels. vu meter a is switchable between channels 1 and 3. vumeter b is switchable between channels 2 or 4. 4 red leds light upwhen the output of the amplifiers exceeds +10 dbm, though don’tworry – there’s still 20db of headroom left in the earlybird!
