LYNX POWERED RADIO INTERFACE AND RADIO POWER LEAD MICRO SYSTEM

The Powered Radio Interface provides the facility to connect a radio transceiver and a mobile telephone, music player, or recording equipment to two Micro System headsets. The interface can be used with either panel mount radios or portable radios.

When the interface is used with two headsets, the equipment forms an installed intercom and radio system which can be powered from the batteries in the Micro System headsets or from an external 12v supply.

The interface accepts interchangeable radio leads to connect to different radios. Each type of lead provides the correct physical connection for a particular radio and automatically configures the interface to provide the appropriate electronic operation. By selecting and connecting the correct radio lead, the interface can be used with any radio.

When using Micro System headsets and an external power supply, the radio is powered via the interface and the headsets are also simultaneously trickle-charged. When powered from an external source the interface will supply the radio with a filtered and regulated power supply at 12, 11, 9 or 6 volts. Two selective PTT inputs are provided to control radio transmissions and to allow each headset to transmit independently. The interface provides an audible “Key Tone” in the headset which confirms when either PTT switch is pressed or released.

In addition to the primary radio connection, the interface can be connected simultaneously to most modern audio devices including mobile telephones, music players and sound or video recording equipment.

Two separate audio devices can be connected to the interface at any one time using the two Audio Sockets. For connection to professional recording devices, the interface provides audio output at both “Microphone Level” and “Line Level.” All of the sound that can be heard in the headsets can be recorded using this method.

During use, the interface monitors the radio and automatically reduces the volume of the audio inputs during radio transmission and reception. This automatic mute feature provides radio priority over any telephone or music input. A buffer delay holds the mute on during radio exchanges and pauses in radio reception.

The interface is also fitted with an Auxiliary Audio Socket, Antenna Shroud and Internal Expansion slots to provide forward compatibility with future Lynx products. The interface may be mounted permanently using Velcro, screws, tube clips or cable tie saddles.
