JMI-111 and JMI-112 Jotron Microphone Interface
Part Number: 102069 / 102411
Jotron Microphone Interface (JMI) is a high-quality microphone interface with one or two inputs. JMI-111A uses one LEMO EGG.2B or PJ7 input. JMI-112A uses two LEMO EGG.2B inputs. Each input has a software selectable microphone sensitivity so that you can plug in several types of microphones. The microphone interface has an advanced microphone amplifier that includes AGC functionality.
JMI Jotron Microphone Interface – high-quality audio
When using the JMI together with Radio Remote Control (RRC), you can configure the RRC so that AGC (VOGAD) regulates low – high signal variations of 40, 50 or 60 dB into a fixed output level. This is important to maximize the audio quality and the modulation level of the transmitter. You can also set other parameters.
Primary power source is the USB input, but the JMI also has dual 10 – 14.4 VDC input for redundancy and high-power speaker output.
