Piano 2.1 Dual-Mono


Recommended Posts

Hi.

 

I have the folllowing setup running Volumio 2.688;

 

Volt Amp with Capacitance Multiplier

Piano 2.1

Kali Reclocker

Rasp Pi 4

 

I've been using it with DSP Dual Mode set to None and Subwoofer 2.2 and it works fine.

 

In anticipation of a soon to arrive Volt+ D I decided to remove the Sub and try setting the mode to Dual-Mono but when I do this I only get sound out of the right channel.

 

I've reflashed the SD card with the latest Volumio and setup from scratch but otherwise not sure where to start workiing out what's going wrong.

 

Has anyone got Dual-Mono mode working with this setup and are there any specific settings I should be looking at.

 

Many thanks

i have about the same problem since i use a kali reclocker / allo piano 2.1 in combination with a raspberry pi 4 i only get sound from sub left and sub right, without kali reclocker it works okay in dual stereo and dual mono.
I use volumio version 2.668.

I use a 5 volt 5 ampere for the raspberry pi 4 and 5 volt 3 ampere for the kali reclocker / piano 2.1.

ps,
the onboard audio on or off in the boot / config.txt makes no difference.

 

Green Mute1 & Mute2 LEDs: DAC Mute status piano 2.1 are on and the power LED is on

In Dual Mono ouput, sound is out on 1 connector of each set (left and sub right)

In volt there is no direct physical sub woofer connection to volt.You have to use externally.
