The WA73-EQ draws inspiration from Rupert Neve’s legendary 1073 module. First introduced in 1970 as part of a 24-channel console, the 1073 quickly became a studio staple thanks to its warm, full-bodied sound. The secret behind this iconic tone lies in its Class-A design and Marinair Radar transformers, which add a pleasing coloration to audio signals. Over time, engineers began pulling original 1073 modules from consoles for standalone use, leading to skyrocketing demand. To address this, manufacturers began creating replicas of the 1073, making its distinctive sound accessible to a wider audience.
Warm Audio is well-known for its cost-effective recreations of classic recording gear, and the WA73-EQ is no exception. Designed to offer the revered 1073 tone without the boutique price tag, the WA73-EQ is a versatile tool for both home and professional studios.
WA73-EQ Build and Design
The WA73-EQ is housed in a sturdy 1U, 19-inch rackmount chassis. At first glance, its robust build stands out, with a solid metal casing and substantial weight, largely due to its large power supply and custom Carnhill transformers. Carnhill—a successor to St Ives Windings, which supplied transformers for original Neve units—ensures that the WA73-EQ retains the sonic characteristics of its predecessor.
Front Panel Controls
The front panel of the WA73-EQ is packed with controls, which might initially seem overwhelming. However, the layout is thoughtfully designed, making it intuitive after a brief adjustment period. Key features include:
- Dual-Concentric Pots: These provide precise EQ adjustments. The knobs feel solid and allow for firm control, a testament to the unit’s build quality.
- Stepped Frequency Selectors: These make it easy to hone in on specific tonal adjustments, ensuring consistency between sessions.
- 80dB of Gain: This high gain level is ideal for capturing low-volume sources like passive ribbon microphones or distant condenser mics.
- Tone Button: This adjusts the impedance of the input transformer, providing subtle variations in tone.
- Output Level Knob: This allows for clean or driven signals, offering flexibility for both pristine recordings and analog warmth.
- Additional Controls: Phantom power, polarity reversal, line/instrument input selection, and insert send/return functionality round out the feature set.
Rear Panel Connectivity
The WA73-EQ’s connectivity options cater to a wide range of studio setups:
- Mic Inputs: Both front-panel XLR and rear-panel XLR mic inputs are available.
- Line Input: A balanced TRS line input lets you process previously recorded tracks or live instruments.
- Instrument Input: A TS jack on the front panel allows for direct input recording.
- Balanced Outputs: Both XLR and TRS outputs ensure compatibility with various setups.
- Insert Points: TS jacks for send and return connections add flexibility for integrating external processors.
- Internal Power Supply: The unit features an IEC connection with voltage selection (115/230 volts) and a ground-lift switch, ensuring stable and interference-free operation.
Inside, the WA73-EQ is hand-assembled using discrete components and through-hole PCBs, ensuring clean signal paths and long-term reliability.
Sound and Performance
The WA73-EQ captures the sonic essence of the original 1073, delivering a warm, rich, and detailed sound. Its Class-A transformer-based design ensures smooth handling of transients and a pleasing low-mid richness. This makes it an excellent choice for recording vocals, guitars, drums, and other instruments.
The WA73-EQ’s EQ Section
The EQ section, based on inductors, is a standout feature. It offers:
- High-Frequency Control: Extended options compared to the original 1073 allow for more precise shaping of high-end detail.
- Midrange Adjustments: Smooth and musical, these controls help bring out the character of vocals and instruments.
- Low-End Shaping: Tight and focused, the low-frequency adjustments ensure a solid foundation in the mix.
The ability to fine-tune these frequency ranges makes the WA73-EQ a powerful tool for both corrective and creative EQ tasks.
WA73-EQ Use Cases
