Knoll MR188 - Manual

Operation:

The MR188 uses very little power so it is normally left on.

If it is powered by the HDMI source, the power is turned off when the
HDMI source is turned off. If you plan for more than 2 weeks without
using the MR188, we suggest unplugging the power source to it.

If you experience any issues with either the sound quality or TV image
quality on the MR188 outputs, try connecting the MR188 power
supply. There are no MR188 user adjustments.

MR188

HDMI to Stereo Adaptor
Installation Instructions v1.0

At last, there is an easy solution to hear content normally confined to
the home theater or TV room, in other rooms and even throughout the
whole home! The MR188 extracts a line level stereo signal from almost
any HDMI signal without changing the HDMI signal “passing through”
in any way. The extracted stereo signal is routed to a stereo or
multiroom amplifier and speakers, giving top quality stereo sound in
locations other than in the home theater.

The internal Dolby® Digital and DTS® decoder down mixes 5.1
channels of digital audio to analog stereo sound so almost all content
can be heard, including movies and other content normally only heard
on the TV or in the home theater. Newer lifestyle products such as

Google ChromeCast

have the ability to play stereo content such as

Rhapsody®, Spotify® and other music, news and a host of other
services. The ChromeCast output connector is HDMI so in order to
hear this content in stereo it needs to be decoded.

The MR188 is normally powered by the HDMI source. In some cases
the source is unable to provide adequate power so a USB to mini USB
cord is provided which can be powered by nearly any USB power
supply.
