Tablo DUAL HDMI and Tablo QUAD HDMI offer two audio modes: Surround Sound Passthrough or PCM (Pulse Code Modulation) audio.

When Surround Sound Passthrough is disabled, PCM audio will be delivered.

Tablo DUAL HDMI and Tablo QUAD HDMI's audio playback settings are as follows:



  • SURROUND SOUND PASSTHROUGH - Allows you to enable passthrough of 5.1 Surround Sound audio to your TV or receiver if they are capable to playing back this sound profile. If you're unsure whether to select this or experience issues with sound, keep this set to OFF. When set to OFF, the Tablo will convert the 5.1 Surround Sound audio to PCM (Pulse Code Modulation) audio to be output and sent to your television.


  • PCM VOLUME MODE - When SURROUND SOUND PASSTHROUGH is set to OFF, the VARIABLE setting allows you to continue to control the volume of programming on your Tablo DVR via the included remote. The FIXED setting will disable the volume keys on your Tablo remote and keep the volume set to 80% of maximum.
