CARDIOID VACUUM TUBE
CAPACITOR STUDIO MICROPHONE
AT4060
The AT4060 is a cardioid vacuum tube capacitor microphone
designed for use in the most demanding studio applications. It
utilizes dual, gold-plated and aged, large-diaphragm elements for
extended frequency response. The AT4060 has a wide dynamic
range of 131 dB and the ability to accept up to 150 dB SPL without
capsule or electronic-system distortion above 1% T.H.D. These
capabilities, coupled with the benefits of exceptionally low self-noise
and very high output, combine in a versatile microphone that meets
the diverse requirements of contemporary recording situations,
while still providing the warm sound of vintage valve design.
The AT4060 is the culmination of extensive field evaluations in
studio environments with resultant significant advances in micro-
phone performance factors. Each hand-selected tube is individually
aged and tested, then employed in a uniquely-configured circuit for
enhanced tube performance. Specially-tuned elements improve
dynamic range and the ability to handle high SPLs without sacrific-
ing high-frequency characteristics. Floating-construction mounting
of the elements provides isolation from noise and vibration.
The AT4060 incorporates a dual-diaphragm configuration that
allows undistorted reproduction of high sound pressure level
signals at all frequencies. The 2-micron-thick, vapor-deposited gold
diaphragms provide accurate reproduction of even the most subtle
sounds, especially high-frequency signals not easily reproduced by
conventional large-diaphragm condenser transducers. For a warm,
true-to-life quality, the dual, large-diaphragm design provides
remarkable low-frequency performance.
The diaphragm of every AT4060 is aged through five different
steps to assure the optimum characteristics achieved will remain
constant over years of use.
The symmetrical housing assembly surrounding the microphone
capsule and its open acoustical environment allow the off-axis
response to be ideally suited for studio work where natural repro-
duction of off-axis sound is of paramount importance.
The AT4060 operates in conjunction with the included AT8560
power supply. The power supply has low-impedance output
(3-pin XLRM-type connector) and a ground-lift switch. Mains voltage
(120V or 230V AC) is selectable via a switch on the back of the unit.
The AT4060 includes an AT8447 shock mount to provide
mechanical isolation and secure mounting. This effective shock
mount fits 5/ "-27 threaded stands. A stand clamp without shock8
mount, the AT8430, is available as an optional accessory.
As with any sophisticated vacuum tube equipment, the AT4060
requires a period of warm-up time before use. Allow at least 15
minutes after switching on the power supply for the unit’s electronics
to stabilize.
Always turn the power supply off while connecting or discon-
necting any cables.
The microphone shall be a dual-element vacuum tube capaci-
tor-type with a cardioid polar pattern and a frequency response of
20 Hz to 20,000 Hz. It shall operate from an external AT8560 power
supply (included) capable of operating from either 120V or 230V AC.
The dual elements shall be internally shock mounted.
Nominal open-circuit output voltage shall be 19.9 mV at 1 kHz, 1
Pascal. The output impedance shall be 200 ohms and output shall
be balanced. The microphone shall accept a 150 dB SPL at 1 kHz
while producing no greater than 1% T.H.D.
A 32.8' (10 m) cable with 6-pin XLR-type connectors shall be
supplied for connection between the microphone and power supply.
The microphone shall have a length of 8.27" (210.0 mm), a
maximum body diameter of 2.10" (53.4 mm), and a weight of 22.6 oz
(640 grams). Finish shall be matte black. A separate AT8447 shock
mount and rack-mount adapters for the power supply shall be
included.
The Audio-Technica AT4060 is specified.
