Providing better quality audio and a vast range of radio/ nav channels than the legacy systems, this Heli-One design allows an upgrade from outdated intercom systems to the latest production standard for the S92 or S76 C++. With this modification, two or three audio panels can be installed. Some main advantages of this panel are the selectable isolation of the flight crew headsets from the passengers, a music input jack, a single passenger audio panel activated by the co-pilot, three maintenance audio including one in the cabin and a built in intercom which will support six passenger/crew headsets. In addition, the audio panel allows enhanced management function by providing control of four outgoing transmissions for five radios, the reception of up to thirteen receivers and the integration of five auxiliary inputs. All these features are added by including a 1A electrical load.
