The Standby switch on BUGERA INFINIUM tube amplifiers is designed to temporarily mute the output signal to the speakers. While it functions similarly to a mute switch, its primary purpose is to protect the power tubes, helping extend their lifespan and ensuring the amplifier operates in optimal conditions.
Function of the Standby Switch
The Standby switch disconnects the output signal path while keeping the tubes powered and warmed up. This is especially important during startup and short breaks, as it allows the tubes to remain in a stable operating state without fully shutting down the amplifier.
How to Use Standby During Startup
Step 1: When turning on the Bugera amplifier, set the Standby switch to ON (Standby mode).
Step 2: Leave it in this position for about 5 minutes to allow the tubes to warm up properly.
Step 3: After the tubes have reached stable temperature, turn off Standby to begin normal amplifier operation.
Following this startup procedure helps prevent electrical SURGES, protects internal components, and increases tube longevity.
Using Standby During Operation
During use, if you need to pause for a short time (for example, between songs or breaks during a session), you can switch to Standby mode to mute the sound without powering off the amplifier.
When you resume playing, simply turn off Standby - there’s no need to wait for the tubes to warm up again.
When to Use or Turn Off Standby
Use Standby when:
Turn off power completely when:
Proper use of the Standby switch not only ensures stable amplifier operation but also extends the lifespan of your power tubes and minimizes technical risks.
Conclusion
The Standby switch is a crucial protection feature on BUGERA INFINIUM amplifiers. Always activate Standby for a few minutes during startup and use it flexibly during your performance breaks. This simple habit can significantly enhance both sound quality and equipment durability, ensuring your amp performs reliably over time.
