Description
The AT4060 is a large-diaphragm side-address vacuum tube condenser
microphone with a cardioid polar pattern. It is designed for use in the

microphone with a cardioid polar pattern. It is designed for use in the
most demanding studio applications.
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 sacrificing high-frequency characteristics. Floating-construction
mounting of the elements provides isolation from noise and vibration.
The microphone operates in conjunction with the included power supply,
which has low-impedance output and a ground-lift switch.

The microphone operates in conjunction with the included power supply,

The cardioid polar pattern of the microphone is more sensitive to sound
originating directly in front of the element, making it useful in controlling
feedback, reducing pickup of unwanted sounds and providing isolation
between performers.

Operation & Maintenance
The AT4060 does not require phantom power but operates in conjunction
with the included power supply. The power supply has low-impedance
balanced output (3-pin XLRM-type connector) and a ground-lift switch,
which allows removal of hum caused by ground loops. The signal appears
across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2
hot”— positive acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be wired
consistently: Pin 1-to-Pin 1, etc.

To set up the microphone with the power supply:
1) Make certain the power supply is turned off.
2) Plug the included 6-pin cable (female connector) into the
microphone; then plug the other end of the cable (male connector)
into the power supply.
3) Connect the output of the power supply into your mixer or other
audio interface (using your 3-pin XLR-XLR cable — not included). Do
not turn on the phantom power.
4) Plug the included IEC power cord into an AC wall outlet.
5) Turn on the power supply.

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.

In use, secure the cable to the mic stand or boom, leaving a slack loop
at the mic. This will ensure the most effective shock isolation and reduce
the possibility of accidentally pulling the microphone out of its mount.

Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 110° F (43° C) for extended periods. Extremely high
humidity should also be avoided.
