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.
