TV/TV Related AV Devices' Connectivity

There are many pairs of red and white RCA jacks on the back of the TV /AV devices, but what we need must be labeled as AUDIO OUT/OUTPUT/AV OUT.

Connect to the 3.5mm audio out jack of your TV, which is usually a headphone port will disable your TV’s internal speakers, not suitable for watching TV with family, it’s better to try this function by a wired headphone before ordering. But if you have already has an external home stereo connected to the TV, then you don’t have to worry about this problem.

If you have a smart TV with only Optical output, or will be buying one in the future, please choose the SIMOLIO digital wireless headsets (SM-823D/SM-824D1/SM-824D2).

For TVs with only Coaxial output, you will need to purchase a DAC for installation.

For TVs with only HDMI (ARC) audio out, you will need to purchase an HDMI to RCA converter for installation.

For AV receivers with a 6.35mm phone jack at the front, you will need to purchase a 6.35mm to 3.5mm audio adapter for installation.

TV Sound Out Setting

Different TV manufacturers have their own definitions for the TV’s sound out. To make your SIMOLIO unit work well with your TV system, please check the sound out setting of your TV first.

If your TV only support single sound out, the TV’s speakers will be either automatically muted when you plug something into an audio out port (AUX, RCA, etc.) or they become disabled once you choose "External Speakers" as your TV's audio output. In this case, you can hook up the SIMOLIO unit to your other TV related AV device, such as cable box or purchase a sound bar + splitter for enjoying TV with your family.

The menus for sound out setting are not the same from different TV brands. please refer to your TV manual for details.

TV & TV Related AV Devices' Volume Setting

Sufficient sound output is needed to ensure Simolio working properly.

VOL.1 > 40%, VOL.2 > 30%, just for your reference. The bigger the VOL.1 and VOL.2, the better the S/N (Signal-to-Noise) of your Simolio unit.

Usually we suggest to fix the VOL.1 to a sufficient level, and adjust VOL.2 to control TV's volume.

If the audio output signal is too weak, it will cause the following problems:

1. no sound from the headset
2. the sound of the headset cuts in and out
3. the headset automatically shuts off every few minutes
