Introduzione
The Warm Audio WA76 is a modern reproduction of the classic '76 Revision D limiting amplifier. It features a fully discrete signal path and utilizes custom CineMag input and output transformers. This unit is designed to provide the ultra-fast attack time and characteristic sound associated with the original '76 compressor, making it suitable for a wide range of audio processing applications.
Caratteristiche principali
- Single channel discrete compressor for professional audio applications.
- Custom CineMag USA Transformers for authentic sound reproduction.
- True to the Classic '76 compressor in design and performance.
- Fully discrete signal path ensures high fidelity audio.
- Supports the famous 'All Buttons In' ratio setting for aggressive compression effects.
Guida all'installazione
Follow these steps to properly set up your Warm Audio WA76:
- Disimballaggio: Carefully remove the WA76 from its packaging. Retain all packaging materials for future transport or storage.
- Posizionamento: Install the WA76 into a standard 19-inch equipment rack. Ensure adequate ventilation around the unit.
- Collegamento elettrico: Connect the supplied IEC cable to the power inlet on the rear panel of the WA76 and then to a grounded AC power outlet. The unit operates on 24 Volts DC power.
- Collegamenti audio: Collega la tua sorgente audio (ad esempio, preamplificatore microfono)amplifier, mixer output) to the input of the WA76 using balanced XLR or TRS cables. Connect the output of the WA76 to your desired destination (e.g., audio interface, mixer input) using balanced XLR or TRS cables.
- Accensione iniziale: Before powering on, ensure all controls are set to their minimum or neutral positions. Power on the WA76 using the front panel switch.
Istruzioni per l'uso
The WA76 features intuitive controls for shaping your audio dynamics. Familiarize yourself with the front panel controls:

Controlli del pannello frontale:
- INGRESSO: Adjusts the input level to the compressor. Higher input levels will result in more compression.
- USCITA: Controls the overall output level of the unit after compression.
- ATTACCO: Determines how quickly the compressor reacts to signals exceeding the threshold. 'FAST' settings (lower numbers) result in quicker compression.
- PUBBLICAZIONE: Controls how quickly the compressor returns to its uncompressed state after the signal falls below the threshold. 'FAST' settings (lower numbers) result in quicker release.
- RAPPORTO: Selects the compression ratio. Available ratios are 4:1, 8:1, 12:1, and 20:1.
- METRO: Displays gain reduction or output level.
Special Operating Mode: 'All Buttons In'
The WA76 can reproduce the classic 'All Buttons In' mode, also known as 'British Mode' or the 'Four Button Trick'. This mode is achieved by simultaneously pressing all four ratio buttons until they latch. This results in an aggressive and distinct compression curve, often characterized by:
- Very aggressive compression ratio.
- Drastic attack and release curves.
- Audible distortion or 'overdrive' on the signal.
- Initial transients may pass through loudly, followed by heavy compression with a 'sucking' effect as the compressor releases.
Note that in 'All Buttons In' mode, the meter function may 'peg out' and not provide accurate metering, which is normal for this specific operational characteristic.

Manutenzione
To ensure the longevity and optimal performance of your Warm Audio WA76, follow these maintenance guidelines:
- Pulizia: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents that could damage the finish.
- Ventilazione: Assicurarsi che le fessure di ventilazione non siano ostruite per evitare il surriscaldamento.
- Magazzinaggio: When not in use for extended periods, store the unit in a cool, dry place, preferably in its original packaging.
- Manutenzione: Refer all servicing to qualified service personnel. Do not attempt to open the unit or perform repairs yourself, as this may void the warranty and expose you to electrical hazards.
Risoluzione dei problemi
If you encounter issues with your Warm Audio WA76, consult the following common troubleshooting steps:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun potere | Cavo di alimentazione non collegato o presa difettosa. | Controllare il collegamento del cavo di alimentazione e provare una presa di corrente diversa. Assicurarsi che l'interruttore di alimentazione sia su ON. |
| Nessuna uscita audio | Incorrect audio connections, input/output levels too low, or bypass engaged. | Verify all audio cables are correctly connected. Adjust INPUT and OUTPUT gain controls. Check if the unit is in bypass mode (if applicable). |
| Rumore/ronzio eccessivo | Ground loop, faulty cables, or improper gain staging. | Ensure all equipment is properly grounded. Use high-quality balanced cables. Adjust gain staging to avoid overdriving inputs. |
| Compression not engaging | Input level too low, or ratio/attack/release settings incorrect. | Increase the INPUT level. Adjust RATIO, ATTACK, and RELEASE controls to achieve desired compression. Monitor the gain reduction meter. |
If the problem persists after attempting these solutions, please contact Warm Audio customer support or a qualified service technician.
