The new DIVO technology automatically adjusts the bias of the output power tubes to ensure their full potential is realized. It monitors the amp’s performance and will isolate faulty tube failures, by running them at half power until the tubes can be changed. The DIVO system also increases the reliability of amplifiers by maintaining the optimum performance of the tubes by performing an ‘in circuit’ test every time the amplifier is powered up.Orange amps will be offering this as option in their new Rockerverb 100 which will be "DIVO Ready." For other Orange amps and most other brands Orange offer the DIVO Orange Tube Sync OV4, a complete standalone unit.
DIVO technology opens up a whole new dimensions in tone options allowing for the first time ever the ability to mix and match tubes. You can experiment with an EL34, 6L6, 6550, KT77 or any other tube type all at the same time in the same amp. With DIVO the Tubes are automatically matched.
DIVO will extend the lifespan of your tubes and never again pay a tech to re-bias
DIVO can be easily integrated into any almost any guitar tube amplifier.
