Web UI Remote Control
Using any modern device with a web browser,
one can access the remote control. When not
logged in as an expert user or installer, the remote
is accessible as well, but the header (above
Main Source) is not visible. The web UI remote
control is best used with a computer or tablet. It
can be used with a mobile phone, but items do
not properly fit the screen. iPad users can also
download the iPad app from the app store.
1. Input Select
Any inputs enabled on the Inputs setup page will
appear here titled according to your setup. See
"Input Settings" . The currently selected input will
be highlighted in blue. Tap any input to select it.

theater by pressing the +/- buttons. One press is
a 1dB increment.

This section contains easy access to select
features.
Mute: Cuts sound to the currently selected
•
theater.

the amount specified in "Parameters". Default

with Dolby may have bass that appears to be
too loud. Use LFE Dim to attenuate the LFE
channel by -10dB.
5. Preset & Audio Decoder Options

into one of these 3 formats. Immsersive
source audio will be rendered natively and this
selection will be grayed out.
