The TCCA STC for the J301A-001 (STC number SH21-8) is applicable to the Bell aircraft series 412/212/205. The J301 is a drop-in replacement for the Andrea A301 Series and the NAT N301A series audio panels allowing for an additional 2 TX/RX positions for a total of 8. The J301 has the flexibility to work with several different ICS Tie line levels simplifying its interface with existing audio systems. The STC can be implemented on an ‘as-needed’ basis. Therefore any quantity of panels within the helicopters audio system can be upgraded, you don’t have to implement them all of them at once.
The J301A-001 audio controller is a compact, lightweight unit that is compatible with the current industry standard interconnect. The unit will support one low impedance headset (5 ohm mic and 8 ohm phones) or one high impedance headset (150 ohm amplified dynamic mic and 150 ohm phones). By using a Windows® based application (ProCS™), configuration settings may be changed via a 3.5mm jack on the front panel. Field replaceable illuminated legends allow one version of the controller for many different mission configurations.
