Description
The AT4060a is a large-diaphragm cardioid condenser tube microphone.
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 tube microphone powering
unit, which has low-impedance output and a ground-lift switch.

Operation & Maintenance
The AT4060a does not require phantom power but operates in conjunction with the
included tube microphone powering unit. The tube microphone powering unit 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.
The microphone includes an AT8447 shock mount to provide mechanical isolation and
secure mounting. This effective shock mount fits
5
/
8
”-27 threaded stands. To use, slide
the microphone into the shock mount basket and tighten the thumb screw to secure the
microphone.
To set up the microphone with the tube microphone powering unit:
1) Make certain the tube microphone powering unit 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 tube microphone powering unit.
3) Connect the output of the tube microphone powering unit 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 AC power cable into an AC wall outlet.
5) Turn on the tube microphone powering unit.
Important: Always turn the tube microphone powering unit off when connecting or
disconnecting any cables.
As with any sophisticated vacuum tube equipment, the AT4060a requires a period
of warm-up time before use. Allow at least 15 minutes after switching on the tube
microphone powering unit for the unit’s electronics to stabilize.
A raised Audio-Technica emblem is on the front of the microphone. Position this side of
the microphone toward the sound source.
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.
Warning:
To prevent fire or shock hazard, do not expose this apparatus to rain or moisture.
Caution:
To avoid electric shock, do not open the cabinet.
Refer servicing to qualified personnel only.
To prevent fire, do not place any naked flame sources (such as lighted candles) on this apparatus.
To prevent fire, do not cover the ventilation of this apparatus with newspapers, table-clothes,
curtains, etc.
Do not expose this apparatus to drips or splashes.
Do not place any objects filled with liquids, such as vases, on this apparatus.
Do not install this apparatus in a confined space such as a bookcase or similar unit.
To install this apparatus only in the place where ventilation is good.
This apparatus should be located close enough to the AC outlet so that you can easily grasp the
power cord plug at any time.
In case of emergency, disconnect the power cord plug of this apparatus quickly.
This apparatus with Class
Ⅰ
construction shall be connected to the AC outlet with a protective
grounding connection.
This apparatus is not disconnected from the mains as long as it is connected to the AC outlet, even if
the unit itself has been turned off.

Important Safety Instructions
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades with one wider than the other.
A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety.
If the provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
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.
The microphone includes a 7.6 m (24.9') output cable terminating in 6-pin XLR-type
connectors for use between the microphone and the tube microphone powering unit.
The microphone is enclosed in a rugged housing. The included AT8447 shock mount
provides superior isolation and permits mounting on any microphone stand with
5
/

threads. A tube microphone powering unit, an AC power cable, rack-mount adapters for
the tube microphone powering unit and a protective carrying case are also included.
