Alto offers audio retrofit for Challengers
By reusing the same PSU grills and implementing 100 per cent fit compatible speakers, Alto helps keep the installation costs low for its new system, making it attractive to Challenger 601, 604 and 605 customers.
Former Baker systems typically employ traditional analogue amps that can be easily replaced by Alto components.

Alto Aviation has introduced a new cabin audio upgrade programme designed to offer a cost-efficient, fast and seamless audio upgrade solution for retrofit Challenger 601, 604 and 605 aircraft.

Former Audio International (AI) digital cabin management systems implemented serially controlled amps and integrated A/V components. To effectively bypass this system limitation, an RS-485 databus reader has been added to an Alto DZ-290 amp to interpret audio settings for audio selection, volume levels, EQ presets and speaker on/off. This serial databus reader allows the existing AI CMS to remain intact but will enable Alto to control the audio path from source to amplification; this way, Alto can get the best audio signal directly to the Alto amp and control the system in tandem with the existing CMS. This integration is vital to preserving the existing AI architecture and minimising the impact on the currently installed CMS.

Former Baker systems typically employ traditional analogue amps that can be easily replaced by Alto components. Often, internal PA audio distribution is sent through the amps. Most Baker cabin management systems can remain intact with minimal impact and redesign. A more comprehensive solution is required when former Baker M2060 and M3070 amps are employed.

Many AI and Baker speakers may be replaced with 100 per cent fit-compatible Alto speakers, making the installation easy and seamless. Alto Aviation offers several loudspeaker models with adapter brackets to fit into the same mounting hole patterns. These brackets make the installation very simple; a real ‘remove and replace’ alternative that simplifies the upgrade path.

“The Challenger aircraft is a top-rated upgrade programme for Alto, and customers appreciate the great sound when they get a new Alto audio system,” says Kevin Hayes, VP of sales and marketing. “By reusing the same PSU grills and implementing 100 per cent fit compatible speakers, we help keep the installation costs low, making it an attractive sale to the customer. Every Alto audio system is supported with an onsite custom tuning by an audio engineer to ensure peak performance.”
