# Warm Audio WA-47 Large-Diaphragm Multi-Pattern Tube Condenser Microphone

**Rich tube character. Nine polar patterns. A professional studio microphone built for vocals, instruments and serious recording.**

The Warm Audio WA-47 is a premium **large-diaphragm tube condenser microphone** designed for recording engineers, producers, vocalists, musicians and studios looking for rich analog character, detailed capture and exceptional versatility from a single microphone.

Built around a custom K47-style capsule, tube-based circuitry and transformer-balanced output, the WA-47 is designed to capture sources with substantial low-frequency body, detailed mids and a smooth, open top end.

With **nine selectable polar patterns**, the WA-47 can adapt to everything from intimate lead vocals and acoustic instruments to room recording, ensembles, guitar cabinets and creative multi-microphone techniques.

For studios looking for one microphone capable of becoming a go-to choice across a wide range of sessions, the WA-47 delivers the flexibility of a multi-pattern condenser with the distinctive character of a tube microphone.

## How Does the Warm Audio WA-47 Work?

The WA-47 is a **tube condenser microphone**.

Sound reaches the microphone's large-diaphragm capsule, where acoustic energy is converted into an electrical signal.

That signal then passes through the microphone's tube-based analog circuitry and transformer before being sent to your microphone preamp, audio interface or recording system.

Unlike a standard condenser microphone that receives its operating power directly from conventional 48V phantom power, the WA-47 uses its **dedicated external power supply**.

The power supply also provides control over the microphone's selectable polar patterns.

The result is a recording system designed to combine sensitive condenser capture with the harmonic character associated with tube electronics.

## Large-Diaphragm K47-Style Capsule

At the heart of the WA-47 is Warm Audio's custom **K47-style large-diaphragm capsule**.

The capsule is one of the most important components in determining how a condenser microphone responds to a source.

Its dual-diaphragm design enables the WA-47's multiple pickup patterns while providing the tonal foundation for its full low end, substantial midrange and smooth upper-frequency response.

That makes the microphone particularly compelling for sources where body, dimension and detail all matter.

## Tube-Based Signal Path

The WA-47 uses a tube within its analog signal path.

Tube microphone circuits can introduce subtle harmonic characteristics that influence how a recording feels before any plugins or processing are added.

Rather than simply capturing a technically accurate signal, the WA-47 is designed to give engineers a microphone with a recognizable sonic personality.

This can be especially useful for vocals and instruments that benefit from additional richness and dimension during tracking.

## Transformer-Balanced Output

The microphone's signal path also incorporates a transformer-balanced output.

The capsule, tube circuit and transformer work together as a complete recording system.

For engineers building an analog-oriented recording chain, this means the microphone itself can become an important part of the final sound rather than merely the first neutral component in the chain.

## Nine Selectable Polar Patterns

One of the WA-47's most powerful features is its **nine selectable polar patterns**.

The external power supply allows the pickup pattern to be adjusted from omnidirectional through cardioid and into figure-8, including intermediate positions.

This gives engineers considerably more control over how the microphone captures both the source and the surrounding room.

### Cardioid

Focus primarily on the sound in front of the microphone while reducing pickup from the rear.

Excellent for applications such as:

-   Lead vocals
    
-   Voiceover
    
-   Acoustic guitar
    
-   Guitar cabinets
    
-   Solo instruments
    

### Omnidirectional

Capture sound from around the microphone.

Useful for:

-   Room recording
    
-   Ensembles
    
-   Natural ambience
    
-   Group vocals
    
-   Acoustic spaces
    

### Figure-8

Capture primarily from the front and rear while rejecting sound from the sides.

Useful for:

-   Duets
    
-   Mid-Side recording
    
-   Room techniques
    
-   Two-sided performances
    
-   Creative microphone setups
    

### Intermediate Patterns

The additional positions between the primary patterns let engineers fine-tune the balance between direct sound, rejection and room ambience.

That makes the WA-47 much more than a single-purpose vocal microphone.

## Built for Vocals

Vocals are one of the WA-47's strongest applications.

Its large-diaphragm capsule and tube architecture can capture a vocal with substantial body while maintaining detail and presence.

Use it for:

-   Lead vocals
    
-   Background vocals
    
-   Voiceover
    
-   Spoken word
    
-   Singer-songwriter sessions
    
-   Pop
    
-   Rock
    
-   R&B
    
-   Jazz
    
-   Country
    
-   Classical recording
    

Changing the singer's distance from the microphone and experimenting with polar patterns can further shape the recording before processing begins.

## Acoustic Guitar & String Instruments

The WA-47 is also well suited to acoustic instruments.

Position it near an acoustic guitar for a detailed mono recording or move it farther into the room to capture more of the instrument's natural interaction with the space.

Its multi-pattern design gives engineers additional control over how much room ambience becomes part of the recording.

The same flexibility makes it useful for strings and other acoustic instruments.

## Piano & Keyboards

Piano can demand both low-frequency extension and detailed transient capture.

The WA-47 can be used as part of a piano-recording setup where its large diaphragm and selectable polar patterns provide several placement possibilities.

For larger studios, a pair can also open up sophisticated stereo recording techniques.

## Guitar & Bass Cabinets

The WA-47 isn't limited to quiet sources.

Its full-range capture can make it an interesting choice for compatible guitar and bass cabinet applications.

Use it alone or combine it with another microphone type to create layered cabinet tones.

For example, a dynamic microphone can provide a focused close sound while the WA-47 contributes body, depth and additional tonal information.

## Drum & Room Recording

The selectable polar patterns make the WA-47 useful for creative drum and room-microphone applications.

Position it farther from the kit to capture the interaction between the drums and recording space.

Experiment with cardioid, omni or figure-8 operation to change how much room information reaches the recording.

For producers, this provides another way to shape the character of the drums before reaching for plugins.

## Nine Patterns Create More Than Nine Possibilities

Polar-pattern selection doesn't simply determine where a microphone hears sound.

It also changes the relationship between the source, microphone and room.

That means the WA-47 can behave very differently depending on:

-   Polar pattern
    
-   Microphone distance
    
-   Source position
    
-   Room acoustics
    
-   Preamp choice
    
-   Gain staging
    

Experimenting with these variables can produce dramatically different recordings from the same microphone.

## Dedicated External Power Supply

The WA-47 operates with its included dedicated power supply.

The power supply provides the microphone's required operating power and allows selection of its nine polar patterns.

This is an important distinction from conventional phantom-powered condenser microphones.

**Do not treat the WA-47 like a standard 48V phantom-powered condenser microphone.**

Follow the manufacturer's connection and power-up procedure and use the supplied power system intended for the microphone.

## Professional Studio Applications

The WA-47 can serve a broad range of recording applications, including:

-   Lead vocals
    
-   Background vocals
    
-   Voiceover
    
-   Acoustic guitar
    
-   Piano
    
-   Strings
    
-   Guitar cabinets
    
-   Bass cabinets
    
-   Drum recording
    
-   Room microphones
    
-   Ensemble recording
    
-   Percussion
    
-   Professional content production
    

Its versatility makes it especially attractive for studios that want one premium microphone capable of handling many different sessions.
