Certified cabin audio systems and passenger controls company Alto Aviation has introduced a new Cadence direct replacement/upgrade programme to solve passenger control obsolescence in retrofit Falcon 900B, older Gulfstream GIV and other aftermarket aircraft equipped with non-serviceable Baker DECU switch panels.

The new Cadence solution, made in the US, replaces and upgrades the obsolete Baker DECU with a drop-in, fit-compatible unit that does not require wood modifications. The replacement upgrades functionality by adding USB-A or USB-C charging ports, 15W, 3A output. The existing wiring may power the charging ports, pending wire gauge and circuit breaker review. The new unit utilises True Blue Power TA-202 supply with limited lifetime warranty.

The design covers up the screws held in the unit. Clear or black anodised bezels are available at no additional charge. Read table and option for Bluetooth headphones is available. Pending production loading, the Cadence panel replacement may be supplied in two weeks or less.

"Alto saw an opportunity to provide customers with a viable alternative to the obsolete Baker DECU," says VP sales and marketing Kevin Hayes. "This Alto solution transforms a nonfunctional unit into a customer-valued added USB-A or USB-C charging port. Utilising Alto's direct fit-compatible approach, the Cadence replacement fits into the same cutout and may use the same wiring that powered the DECU unit. In addition, the replacement is installation-friendly and increases user value by adding USB charging within the same profile."
