6.1 MICROPHONE JACK
6.1.1 Connector Pinout
6.1.2 Supported Microphone Types
The FLEX-6000 front microphone connector can support either a dynamic or an electret
microphone. This is a pseudo-balanced nominal 600 ohm impedance input. The electret
bias voltage is not enabled by default, and must be enabled by SmartSDR. The supplied
FHM-1 does not require the electret bias voltage to be enabled.
6.2 HEADPHONE JACK
The FLEX-6000 supports a stereo headset to allow for advanced audio routing features. The
headphone jack is a ¼ inch TRS phone plug. Do not use a mono or TS connector that
grounds the “ring” portion of the connector. There is a separate master headphone level
control for the radio and LEFT-RIGHT (pan) slider control on each Slice Receiver. Refer to
the SmartSDR Software User’s Guide for more information on controlling the audio to the
headphone jack. Use high quality stereo headphones or a stereo communications headset
for best results. Minimum headphone impedance is 16 ohms.
6.3 CW KEY/PADDLE JACK
The CW key/paddle jack is a ¼ inch TRS phone plug. For an iambic paddle, the tip is
connected to the dot paddle, the ring is connected to the dash paddle and the sleeve is
connected to the common. For a straight key or a keyer output, connect to the tip and
leave the ring floating. The common is connected to the sleeve. (Note: 3.3VC Max input.)
