Meridian FAQ

How do I connect the configured HD621 to another Meridian digital product?

Using a digital coaxial (S/PDIF) cable, connect one end from the digital output on the HD621 marked
‘1/2’ to the required digital input on the other Meridian component.

How do I control HDMI source switching via remote control?

This is only possible if you have a Meridian component in the system that can act as a Controller.
These are either certain models of DSP Loudspeaker, Surround Controller and the 818 Reference
Audio Core.

• HD621 to DSP8000/DSP7200/DSP5200 requires BNC comms

• HD621 to Surround Controller & 818 Reference Audio Core requires a 5C lead

How do I connect the configured HD621 to a non-Meridian product?

Using a digital coaxial (S/PDIF) cable, connect one end from the digital output on the HD621 marked
‘1/2’ to the required digital input on the non-Meridian component.

In this configuration is not possible to remotely control HDMI source switching - this is only possible
by pressing the appropriate hard key on the HD621.
