ALTO Aviation Introduces New ALTO M1285R Chime/Tone Warning Amplifier with 12 Tones

ALTO Aviation, a supplier of high-end cabin audio and entertainment systems for business aviation, announces the availability of its new chime/tone warning amplifier, ALTO M1285R.

The ALTO M1285R is a direct fit, pin-compatible chime amplifier replacement for aircraft cockpit or passenger address tone generation, designed by ALTO Aviation engineers to provide a replacement for the now obsolete Baker M1285. The chime/tone warning system has both an identical main connector and pinout, as well as identical mounting footprint, as the original Baker M1285.

The unit has 12 available tones which can be triggered by high or low opto-isolated discrete logic inputs. The amplifier has an audio power amplifier output supporting loudspeaker loads down to 4 ohms and up to 30 watts. The amplifier has two line outputs capable of providing 40mW into 600 ohm. The unit is fully configurable via a custom software interface for easily adjustable custom tone and volume settings.

The ALTO M1285R unit is certified to TSO-C-139a. The software is certified to DO-178B Level D. It carries a five-year (5) guarantee and is available for all aircraft platforms.
