Alto Aviation has introduced a seamless retrofit cabin audio upgrade for Bombardier Challenger 601, 604, and 605s. According to Alto, its solution keeps the existing cabin management system (CMS) intact while adding an Alto DZ-290 amp to provide better audio quality, making it a cost-efficient upgrade.

On Challengers with Audio International (AI) CMSs, the amp includes an RS-485 databus reader that allows it to bypass the CMS’s limitations, namely serially controlled amps and integrated audiovisual components. This means the amp can interpret audio settings for audio selection, volume levels, EQ  presets, and speaker on/off.

For those with installed Baker systems with traditional analog amps, the Alto upgrade keeps the CMS intact and requires only minimal redesign. However, the company said a more comprehensive upgrade solution is required when Baker M2060 and M3070 amps are employed.

Additionally, many AI and Baker speakers can be form-fit replaced with Alto speakers using adapter brackets, the company added.

Challenger “customers appreciate the great sound when they get a new Alto audio system,” said Alto v-p of sales and marketing Kevin Hayes. “By reusing the same power supply unit grills and implementing 100 percent fit compatible speakers, we help keep the installation costs low, making it an attractive upgrade.”
