AUDIO TECHNICA 4040 CARDIOID During the early 90s, the Audio-Technica 4 series caused a sensation within the pro recording industry. The performance was equal to or surpassed, the established elite on all counts, and at a fraction of the cost. The 4040 builds on that legacy. The capsule is a genuine externally polarised condenser variety. The gold sputtered diaphragm has completed an ageing process so long term stability is assured. The response is held within tight limits between 20Hz and 21kHz. The large diameter of the capsule ensures the low frequency detail is retained which explains why the 4040 is popular with male vocalists. There is a switched 80Hz, 12dB/octave low frequency roll off filter and a 10dB attenuation pad to extend the maximum SPL level to 155dB. The typical overall dynamic range is 133dB and the signal to noise ratio 82dB. Supplied complete with AT8449 shock mount threaded 5/8 inch, protective carrying case and a dust cover. 48volt phantom powering.
