HOW DOES IT WORK?

MixTwoJacks is plug & play, designed for the fastest and most intuitive setup.

You can easily integrate it into your audio system by following these 5 steps

1. Connect your own headphones to the OUT output

2. Connect the IFB to the ST input using a TRS mini-jack cable

3. Connect the PTT cable’s mini-jack connector into the M input

4. Connect the PTT cable’s 2-pin connector to the walkie-talkie​

5. Use the walkie-talkie normally, using the microphone on the PTT cable for communications

PERSONALISED TRIM ADJUSTMENT

Different walkie-talkie models vary in output level and voltage.

Some models may have excessively loud volume even at minimum settings, or they may produce noticeable ‘bumps’ when the push-to-talk microphone is activated.

This can be corrected with the trimmer on mixtwojacks, which adjusts the circuit for any walkie-talkie model by adding a variable resistor to the M input, keeping the ST input level unchanged.

To adjust the M input level, turn the trimmer with a small screwdriver.

MixTwoJacks PTT (Push-To-Talk) Cable

To use the walkie-talkie with mixtwojacks, you need a PTT cable.

This cable allows you to send the walkie-talkie’s audio output to mixtwojacks and monitor it through your own headphones.

Despite the wide variety of walkie-talkies available, the most common 2-pin connector standards are primarily:

• Motorola
• Kenwood
• Midland
