The MaxColor Series 2 Transmitter and Series 2 Receiver - MC-TX2 and MC-RX2 - add support for Audio Return Channel (ARC) when used in a point-to-point connection between a display and AVR that both support ARC.
MaxColor Series 2 devices support ARC. They do NOT support eARC.
MaxColor Series 2 devices do NOT have ARC enabled by default. ARC must be enabled and the system properly configured to use ARC. The instructions below detail how to enable and configure ARC.
ARC pass-through involves connecting a MaxColor Series 2 Transmitter and Receiver between the HDMI ARC port of a display and the HDMI Output port of an ARC-enabled AVR. A switch can be used to connect the devices together, but is not necessary.
ARC is not enabled by default. When ARC Pass-through is enabled, the Transmitter and Receiver are put into unicast mode. This means that the two ARC devices can only watch each other - no other Transmitter or Receiver in the system will be able to interact with those devices. Apply the settings below to enable ARC Pass-through.
Telnet to the MC-RX2 connected to the ARC display and apply the command below:
astparam s multicast_on n;astparam s no_cec n;astparam s no_arp n;astparam s access_on_c y;astparam s access_on_i y;astparam s a_arp_input hdmiout;astparam s a_arp_publish_on n;astparam s cec_forward_rule 0xff;astparam s btn1_long e_btn_request_arp;astparam save;reboot
The Receiver will reboot into unicast mode with ARC enabled.
Telnet to the MC-TX2 connected to the HDMI Output of the ARC AVR and apply the command below:
astparam s multicast_on n;astparam s no_cec n;astparam s no_arp n;astparam s cec_forward_rule 0xff;astparam s btn1_long e_btn_request_arp;astparam save;reboot
To return the ARC devices to their default settings, telnet to each device and apply the command below:
astparam s multicast_on;astparam s no_cec;astparam s no_arp;astparam s cec_forward_rule;astparam s btn1_long;astparam save;reboot
