Mounting Microphone

Mounting Location

Mount the microphone on the rear-view mirror, headrest, sun visor, or other appropriate location.

We recommend that you mount it on the sun visor.

1.Attaching the microphone

After mounting the microphone, use the supplied cord clamp to dress the microphone cable.

You can use the internal microphone in the monitor (TMI-M990, sold separately) as a Road EQ Microphone. For more details about connecting, refer to “Examples of system expansion” (page 13).

When connecting two PXI-H990s, connect the microphones to both units. In this case, the mouting location of two microphones should be the same.

When connecting two PXI-H990s, the Road EQ microphone built in the monitor (TMI-M990, sold separately) cannot be used.
