    The Pro series Boomsets are designed to meet the high standards of the most critical Multi-Op Contesters and DX'ers. Their search for a lightweight comfortable headset and fully flexible boom was our inspiration for developing this latest addition to the Heil product line. All of the Pro Series Headsets are designed to be worn for extended periods of time and provide the highest quality sound possible. All models work in VOX or  P.T.T. modes. The headband has detentes on each side for adjustment and is fully padded for comfort.

    The Pro Series Boom is a fully flexible material that makes mic placement virtually unlimited. They even swivel up for travel, storage or headphone use only. Each Boom comes equipped with your choice of Heil "Key Element" microphone cartridge (AD-1 adapter needed).
 

The Pro Set offers all of the features found in the Pro Series. The ear pads are heavily stuffed, cover the entire ear, seal out noise, and are removable for washing. The Pro Micro is an incredibly lightweight boomset. It is a miniature version of the Pro Set. It is designed to allow the user to hear background noise and does not cover the entire ear. The Pro 5 is designed to answer the many requests for a single sided Boomset that will allow the operator to monitor other radios during operation. The ear pad is heavily stuffed, covers the entire ear, seals out noise, and is removable for washing.   The HM Series Microphones       The HM  Series Microphones are developed for the operator that desires a hand held or desk mounted mic. The MA-1 (Adjustable Boom) and TB-1 (Table Base Mic Stand) are among the products Heil offers to mount the HM Series Microphones.      The HM series is unique because it offers a choice of Heil "Key Elements" or a combination of two. This "dual" configuration gives the operator the ultimate in articulate audio flexibility. Each HM Series microphone comes with its own carrying case and boom clip. The clip can be attached to either the MA-1 or TB-1 for desk mounting. The HM series has a built in P.T.T. button or can be used in VOX mode.   The HM-10 Microphone contains all the features of the HM series and is equipped with the Heil "Key Element" microphone cartridge of your choice. The HM-10-Dual contains all the features of the HM Series microphones (as shown) and is equipped with two Heil "Key Element" microphone cartridges. Standard configuration is the hc-4 and HC-5 elements.   The HC Series Microphone Elements      The Heil HC Series Element is the single most important ingredient for improving your sound. Most communications microphones today were designed for public address. Their mushy, bassy sound was great for egos but did nothing to improve voice clarity and frequency articulation. Designed for amateur radio, the HC series elements take articulate SSB audio to another level. Its tiny size and easy installation makes it a perfect replacement cartridge for most microphones. With today's DSP equipped radios, the Heil "Key Element" is the perfect choice. Articulate audio starts at the microphone, not the DSP Circuit. By tailoring the element's frequency response, we allow the DSP Circuit to compliment the microphone instead of trying to process poor originating audio. The result is clear, articulate, pile-up cutting audio critical for DX, Contest and Rag Chewing alike.      The Heil Pro Series and HM Series are all equipped with the HC series microphone cartridges. All elements have cardioid polar pattern forward. The high and low end roll offs are appropriately set at 12dB per octave.     The HC-4 or "DX Dream Machine", is the microphone cartridge for Contest and DX operators. Engineered with a frequency response designed to cut through the pile-ups, this element actually places a 10dB rise at 2,000Hz (a frequency the human ear is highly responsive to). Frequency: 500Hz to 3,800Hz with 10dB rise at 2,000Hz. Sensitivity: -66 dB Nominal Impedance: 2,000 ohms @ 1,000Hz. Size: .530 x .850 x .310 The HC-5 or "The Key Element", is the microphone cartridge for everyday Rag Chewing. Engineered with a frequency response designed for a fuller range of articulate voice clarity. Not mushy, bassy, paging type audio, but clear, easy to understand SSB audio. This element places a 6dB rise at 2,000Hz (a frequency the human ear is highly responsive to). Frequency: 350 Hz to 4,000Hz with a 6dB rise @ 2,000Hz. Sensitivity: -68 dB Impedance: 2,000 ohms @ 1,000Hz. Size: .530 x .850 x .310 Microphone Adapters and Accessories AD-1 CC-1 The AD-1 and CC-1 adapters are a product of necessity for the operator that has more than one radio. By leaving the adapters plugged in your radio, you can move from transceiver to transceiver with the Pro Series or HM Series microphone/Boomset without having to rewire the microphone for each individual radio. All Heil Microphones/Boomsets require the appropriate adapter to mate them to your particular model transceiver. Each adapter is color coded as follows: Kenwood=Red; Icom=Blue;  Ten Tec=Black; Yaesu=Yellow; Collins=White; Drake=Purple Custom orders are available for other brands. The AD-1 and CC-1 Series adapters come in 4 pin, 8 pin and modular style connectors. The TB-1 Table Base, for the HM Series, features a cast base (2lbs. 10oz.) and stands 6" high. Its non-skid cork feet make it the perfect piece for desk mount operation. The MA-1 Boom and Clamp Assembly, for the HM Series, is a telescoping articulate boom. It is equipped with a clamp for mounting to a shelf or table. It has three holes in the base for more permanent mounting applications and rotates 360 degrees. This places the HM Series microphone exactly where needed. The FS-1 Foot Switch is the ultimate in hands-free operation. With its non-skid rubber pads on top and bottom, the FS-1 controls the P.T.T. Function via your foot. This allows you to write, type or perform other tasks while you operate. It's terminated in a mono 1/4" phono plug which simply plugs into the AD-1 or CC-1 adapter. The HS-1 Hand Switch is a rugged, high quality hand switch made for P.T.T. operation. Its shape fits naturally and comfortably in the hand. It's equipped with a generous 6' of cable and is terminated in a 1/4" phono plug which simply teminates in the AD-1 or CC-1 adapter.
