Bluetooth
The MX123 can pair with many Bluetooth devices.
A maximum of 8 Bluetooth device pairings will be
remembered. A ninth pairing will replace the oldest
registered device. For Bluetooth Remote Control of
the MX123 to function, the device must support the
AVRCP profile. Supported functions are play, pause,
stop, next, and previous. The connected device’s
volume will control the level of the signal sent to the
MX123.
To pair a Bluetooth device with the MX123:
• Activate the Bluetooth setting on your mobile
device
• Press and hold the Bluetooth button on the
MX123 Remote Control for at least 3 seconds
• Select the MX123 from the list of discovered
devices on your mobile Bluetooth device
The Option Button
The Remote Control’s OPTION button can be used
in the MAIN Zone to adjust settings for the selected
Input. Adjustments include:
• Dialog Enhancer- this function adjusts the
center channel frequency band to enhance the
dialog in the movies and vocals in music for
easier listening
• Channel Level Adjust - each channel can be
adjusted -12dB to +12dB while listening to
music
• Tone- tone can be adjusted and stored for each
channel. Tone can not be set if Sound Mode is
set to Direct or Pure Direct or when Dynamic
EQ is set to On
• Picture Mode- sets Picture Mode for
supported Inputs. For options see “Picture
Adjust” on page 20
• All Zone Stereo- allows you to play music
from the MAIN ZONE into ZONE2 and
ZONE3. This will work for all Input modes
except 7.1CH IN
The Headphone Question
The All Zone Stereo option allows you to send
analog stereo sound from a compatible HDMI signal
to a unit such as a headphone amplifier connected
to Zone2 or Zone3. This will allow you to listen
via headphones given that you have headphones
and an amplifier. You can mute the MAIN ZONE
and continue to listen to stereo signals from units
connected to the other Zones.
