The DIO headphones with reed/auto start function can be used to start and stop your content automatically. This can be done when connected to a media player that can be programmed to accept this input like the AP 01 or the MP 01.

Wiring your DIO with Reed to a Molitor Media Player

The wiring of the DIO with Reed is similar to our standard VIA and USO handsets, however the wires for the reed input come from the hanger and not the headphones themselves.

The headphones should be plugged in as usual into the headphone jack of the player; the volume of the output can be adjusted via the volume knob.

The reed input wires come from the included headphone hanger. The two wires from the hanger should be wired into the Reed and GND inputs of your Molitor AP 01 or MP 01.

Basic Principle

When using DIO (Direct Input/Output) headphones with a REED contact option, the REED switch acts as a sensor to detect whether the headphones are picked up (removed from their magnetic holder) or placed back.

REED Switch Behavior

The REED switch for DIO headphones is inverted compared to the standard USO/VIA configuration.
Inversion means: The circuit logic is reversed; instead of closing the contact when the handset is on the magnet (as with standard configurations), the REED on DIO will close or open the contact in the opposite state.

Setup Instructions

To ensure that playback starts as soon as the headphones are picked up from the magnet (triggered by the REED contact), you must:

Set in your playlist configuration.  sw_active=1

This setup ensures the player detects the state correctly and begins playback immediately after the headphones are removed from the holder.
