External Connections; Microphone Jack Mic; External Speaker - Albrecht AE 6891 Bedienungsanleitung

You can only transmit in AM with your radio if you have programmed the 80/40 or 40/40
mode and if you select a channel, where AM is permitted for transmission.
As soon as you try to switch to one of the channels 41 to 80 on AM, the device switches to
40-channel AM mode with channels 1-40 (and vice versa for German setting).
Both modulation modes have their own channel setting, so that after switching always the
previously used FM or AM channel is selected.
Channel 1
Channel 9
Channel 19

Channel 40

Microphone jack 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!
