The new Astatic 1104C pre-amplified base station microphone offers modern styling, modern features, along with the sound and talk power made famous by the Astatic D104 for over 40 years. The amplifier has easily accessible slide controls for volume and tone adjustment so that correct output level and tone quality can be set for each operators voice. A master gain control, accessible only through the open battery replacement door, can be adjusted to prevent over modulation and distortion. The audio line is open on receive. This is a handheld, PTT microphone with adjustable output.
Frequency response is tailored for voice output.
The mic performs well over entire impedance range from 100 ohms to open circuit. An output impedance compatible with the inputs of almost all commercial transceivers and externally adjustable high gain amplifier ensures desired modulation level. The 575M-6 has easily accessible slide controls for volume and tone adjustment so that the correct modulation level and tone quality can be set for each operators voice. The 575M-6 has a six wire coil cord which allows for relay, electronic or virtually any type hookup with almost any transceiver. The audio line is open during receive.
