# WA273-EQ Dual Channel British Mic Pre + EQ Warm Audio Tech/Pro Audio Gear

## Warm Audio WA273-EQ Dual-Channel British-Style Mic Preamp & 3-Band EQ

**Two channels of rich analog tone. Powerful EQ. Professional studio flexibility.**

The Warm Audio WA273-EQ is a professional **dual-channel microphone preamplifier with 3-band EQ** designed for recording engineers, producers, musicians and studios looking for the rich, full character associated with classic British console-style recording.

With **up to 80 dB of gain, premium Carnhill transformers, discrete circuitry and independent EQ control**, the WA273-EQ gives you two powerful channels for capturing and shaping vocals, drums, guitars, bass, keyboards and other instruments.

Whether you're building a professional recording studio, upgrading an audio-interface-based setup or adding analog character to an existing signal chain, the WA273-EQ brings serious outboard processing capability to your rack.

### How Does the Warm Audio WA273-EQ Work?

A microphone produces a relatively low-level signal.

Before that signal can be properly recorded, it needs to be amplified to a usable level—and the quality and character of the microphone preamp can have a major influence on the resulting recording.

The WA273-EQ takes your microphone, line-level or compatible instrument signal and runs it through a discrete analog signal path with Carnhill transformers.

From there, you can use its onboard EQ to shape the sound before sending it onward to your audio interface, converter, recorder or other studio equipment.

Because the WA273-EQ provides **two channels**, you can record two sources simultaneously or use it for stereo recording techniques.

### Up to 80 dB of Gain

The WA273-EQ provides up to **80 dB of gain**, giving engineers substantial amplification capability for a wide variety of microphones and recording situations.

That makes it useful with:

-   Condenser microphones
    
-   Dynamic microphones
    
-   Ribbon microphones
    
-   Drum microphones
    
-   Vocal microphones
    
-   Instrument recording setups
    

Rather than simply making a signal louder, the WA273-EQ is designed to impart a distinctive analog character as the signal travels through its circuitry and transformers.

### Carnhill Transformer-Balanced Signal Path

A defining part of the WA273-EQ architecture is its use of **Carnhill transformers**.

Both channels employ a discrete, transformer-balanced signal path designed to deliver the rich, dimensional character associated with classic British-style studio equipment.

Depending on how you set the gain structure, the WA273-EQ can be used for relatively natural amplification or pushed harder when additional harmonic character and analog coloration are desired.

### Independent 3-Band EQ

Each channel includes a dedicated **3-band EQ section**, allowing you to shape the signal directly from the analog preamp.

This gives engineers the ability to adjust important frequency areas before the signal reaches the recorder or audio interface.

Use the EQ to:

-   Add presence to vocals
    
-   Shape electric guitars
    
-   Add body to instruments
    
-   Control excessive low frequencies
    
-   Add definition to drums
    
-   Sculpt bass and keyboard sources
    
-   Shape stereo microphone recordings
    

The EQ can also be switched independently, giving you the flexibility to use the WA273-EQ as a preamp with or without additional equalization.

### High-Pass Filtering

Unwanted low-frequency energy can quickly consume headroom and make a recording sound muddy.

The WA273-EQ includes high-pass filtering to help reduce unnecessary low-frequency information such as rumble and other unwanted bass content.

This can be particularly useful when recording vocals, acoustic instruments and other sources that don't require extremely low frequencies.

### Two Channels for Stereo & Multi-Mic Recording

The dual-channel design provides considerably more flexibility than a single-channel preamp.

Use both channels for:

**Stereo Piano** — Connect a pair of microphones for a spacious stereo piano recording.

**Drum Overheads** — Capture left and right overhead microphones through matching preamp channels.

**Acoustic Guitar** — Combine two microphones or different microphone positions.

**Vocals + Instrument** — Record a vocalist and instrument simultaneously.

**Stereo Keyboards & Synths** — Process compatible left/right signals through analog circuitry.

**Room Microphones** — Build stereo ambience and room-mic configurations.

For studios that routinely record more than one source, having two matching channels can be extremely valuable.

### Instrument & Line-Level Connectivity

The WA273-EQ isn't limited to microphones.

Its connectivity supports microphone, line-level and instrument applications, making it useful throughout a professional studio.

Plug a compatible instrument directly into the unit for recording, or incorporate line-level equipment as part of a larger analog production workflow.

This makes the WA273-EQ useful during both **tracking and mixing**.

### 48V Phantom Power

Each channel provides **48V phantom power** for compatible condenser microphones and other equipment that requires phantom power.

This allows the WA273-EQ to become the front end for a wide variety of professional studio microphones.

### Polarity Control

Polarity inversion is available for situations involving multiple microphones and complex recording setups.

This is especially useful when recording drums, guitar cabinets, piano or other sources with multiple microphones where polarity relationships can affect the combined sound.

### Insert Capability

The WA273-EQ provides **switchable send/return inserts**, allowing additional analog processors to be incorporated into the signal chain.

For example, an engineer can integrate compatible:

-   Compressors
    
-   Additional equalizers
    
-   Outboard processors
    
-   Studio effects
    

This makes the WA273-EQ more than a standalone preamp—it can become the foundation of a sophisticated analog recording chain.
