CARDIOID CONDENSER MICROPHONE

- Transformer-coupled output and a specially tuned element provide

warm sonic characteristics reminiscent of early F.E.T. studio microphone

designs

- Exceptionally wide dynamic range, low self-noise and high SPL

capability for maximum versatility

- Dual-diaphragm capsule design maintains precise cardioid pattern

denition across the full frequency range of the microphone

- Precision-machined, nickel-plated brass, acoustic element bafe

provides enhanced element stability and optimal sensitivity

- State-of-the-art surface-mount electronics ensure compliance with A-T’s

stringent consistency and reliability standards

The AT4047/SV is intended for use in professional applications where

remote power is available. It requires 48V DC phantom power, which may

be provided by a mixer or console, or by a separate, in-line source such

as the Audio-Technica AT8801 single-channel or AT8506 four-channel

phantom power supplies.

Output from the microphone’s XLRM-type connector is low impedance

(Lo-Z) balanced. 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.

An integral 80 Hz hi-pass filter provides easy switching from a flat

frequency response to a low-end roll-off. The roll-off position reduces the

microphone's sensitivity to popping in close vocal use. It also reduces

the pickup of low-frequency ambient noise (such as trafc, air-handling

systems, etc.), room reverberation and mechanically-coupled vibrations.

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 43°C for extended periods. Extremely high humidity

should also be avoided.
