Heil Sound PRO7RD Industrial Headset with Dynamic Element, Red

The Heil Sound Pro 7 is an aviation - style headset crafted for amateur radio use in noisy environments. Its specially designed foam - gel ear pads offer 26 dB of outside noise reduction and outstanding comfort. As a true dual - channel, stereo headset, the Pro 7 Series has an audio balance control. This lets you adjust the left earphone level to match the right. A unique phase - reversal switch helps you pick up weak signals easily. The latest Pro 7 version comes with a monitor jack, allowing a second operator to plug in headphones and listen to the audio. The low - distortion Dynamic HC - 7 microphone element has a frequency response from 100 Hz to 12 kHz. It has a traditional Heil speech articulation rise centered at 2K - 4KHz with well - balanced highs and lows, and an impedance of 600 ohm. The HC - 7 is great for clear speech. Key features include a large PTT switch, military - grade straight and coiled cables, an extra set of ear pads, and washable cotton ear pad covers. Technical specs: it has options for generating element (Dynamic iC | iC Electret), frequency response (100 Hz - 12 kHz | 35 Hz - 12 kHz), polar pattern (Cardioid | Cardioid), impedance (600 Ohms | 1.5 k ohms), output level (-57 dB at 1 kHz | -48dB at 1 kHz), weight (17 oz | 17 oz), and requires an AD - 1 Series adapter (AD - 1 - iC included).

Using the Heil Sound Pro 7 headset is easy. First, put on the headset and adjust the ear pads to fit your ears comfortably. The large PTT (Push - To - Talk) switch makes it simple to start and stop transmitting. Use the audio balance control to set the sound levels in both ears to your liking. If you're having trouble hearing weak signals, try using the phase - reversal switch. For sharing audio, plug a second set of headphones into the monitor jack. When it comes to maintenance, the cotton ear pad covers are washable, so you can keep them clean. Also, make sure to store the headset in a dry place when not in use. When handling the cables, be gentle as they are military - grade but still need proper care. Always use the recommended AD - 1 Series adapter to ensure proper functioning.
