Hand mic, external speaker and microphone: radio in a noisy cab
In the cockpit of an all-terrain vehicle or bulldozer, the station is heard the worst: the engine, transmission, wind into an open window. The two-way radio itself is not to blame here - accessories decide in the noise: where the speaker stands, what microphone and how to reach it. Let's take it one by one.


A speaker is the first thing you need in a noisy technique
Built-in speaker GM340 - 3 W. For a passenger car, it is enough, for a tractor cab or tracked vehicles - not. Motorola provides for the station external speakers at 7.5 and 13 W.
The remote speaker is placed closer to the driver, and not where there is space: on the panel or rack, pointing towards the head. Example: remote speaker GMSN4078BIt is carried on the dashboard so that the call can be heard over the engine. Compatibility with the connector of a particular station is checked by model.
Hand microphone: under the hand and glove
The regular hand-held microphone. GMN6146Motorola factory accessory for vehicle-mounted stations. It is hung on a hook in the range of the right hand, so as not to reach on the move.
Where there is talk and on the move, take MDRMN4025 remote microphone For GM-series stations: speech is legible, hand microphone is more convenient.
Work at the open door and on the street
If the driver often speaks while standing at the car - on loading, on the drilling, on the crossing - you need a microphone that is not afraid of rain and wind. MDPMMN4027 - waterproof, IP57 class, with Windporting wind protection.
When you need a headset or external periphery
In the noisiest cars and where the hands are always on the levers, a headset or other periphery is connected to the station through an accessory connector. For GM and DM series stations, this is connector HLN9457For the DM3000 and DM4000 PMLN5072.
How to run wires
- Wire hand microphone - with a margin for turning the body, but so that it does not fall under the pedals and levers.
- Wire speaker and power supply - away from the steering column and movable parts of the seat.
- The connectors are inside the cabin: in the street they are stuffed with dust and water.
What to clarify when ordering
The station model, the type of equipment, how noisy it is in the cockpit, whether the driver is wearing gloves, and whether he leaves the car with a microphone. Send this letter to office@apocalypsemoto340.ru - select a speaker, hand microphone and connectors in one set.
