Heil Sound BM-17 IC Single
Single-sided headset for civilian - mission-critical communications with ICOM capsule
WARNING!!! The AD-1-IC8 adapter cable is NOT included in the offer
The BM-17-Dynamic headset uses the BM-D dynamic element designed specifically for use in communications. This 500-ohm dynamic element works on most amateur radio platforms that require a Low-Z input impedance (usually between 150 ohms and 4k ohms). Radios that require a high impedance input of 10k to 30k ohms require the use of an XT-1 impedance matching transformer. The BM-17-Dynamic has an operating frequency response of 120Hz - 10 kHz.
The BM-17-iC headset, using our iC electret element, was created for use with Icom radios. Working with Icom America, this element was created to eliminate low gain audio on some earlier and non-professional series radios. This element must be paired with the iC-AD-1-iC adapter (included) or AD-1. iC adapters do not have internal DC blocking capacitors, so bias voltage can be passed through, allowing the iC electret element to operate. The iC element has an operating frequency response of 35Hz - 12kHz.
The microphone audio for the BM-17 series terminates in a 1/8" mono jack while the headphone terminates in a 1/8" stereo jack (1/8" to 1/4" adapter included).
The boom is designed to be extremely flexible and is rotatable on the headphone speaker for optimal positioning in any situation.
The use of AD-1 series microphone adapters allows for a simple interface with the most popular transceiver inputs. The adapter is 6-8" long and has a 1/8" female input jack for the headset microphone while the 1/4" female coming out of the adapter is the PTT (push to talk) line for the Heil foot switch or hand switch. The 1/8" or 1/4" stereo jack should be inserted into the headphone jack on the front panel of the transceiver.
