Microphone 6 pin socket MIC
Your radio features a 6-pole special jack, which allows up and down channel selection. In case you
want to use a different microphone, please note that the channel selection might not be available in
the microphone. Wiring corresponds with the common GDCH standard and is also common for
alternative microphones.
PIN 1 Microphone audio approx. 3mV / 1000 Ohm with power supply
PIN 2 PTT RX (receiver contact on GND = speaker GND)
PIN 3 PTT TX (transmission contact on GND)
PIN 4 Additional functions Up / Down
PIN 5 GND, shielding
PIN 6 Power supply for microphone amplifier
The microphone jack is intended for all microphones including preamp or for data transmission or
PC sound card connection (e.g. as gateway).
For data and gateway operation pins 4 and 6 should not be used. The cable length at these pins
can be up to 3m (shielded cable only).
In some countries (e.g. Germany, Switzerland and the Netherlands) also external devices for data
transmission (e.g. packet radio) or Internet gateways can be connected. This kind of data
transmission is only permitted on certain channels and only for hobby applications. The permitted
channels are not the same for all countries, please find out more (for instance via the CB clubs)!
Do not use channel 40 for data transmissions near Switzerland, since this is their call channel and
not intended for data transmission.

External Speaker

Your AE 6890 features a 3.5mm mono jack at the rear to connect an external radio speaker. Upon
connection the internal speaker is automatically muted. The external speaker should have 4 to 8
Ohms impedance. Our range of accessories offers a variety of suitable speakers.
Please note that NF Out is very strong and adapted for 4 and 8 Ohms as transformer-coupled
amplifier, thus can produce high volume.
A connected speaker should be designed for at least 4 Watts or more continuous output!
