Lipsync
There may be times when a particular Audio/Video
Program has a synchronization difficulty between the

noticable when a person is talking and the movement
of their Lips is delayed from the sound you are hear-
ing. The MX151 has the ability to add delay the sound
in 10 milliseconds (ms) increments up to 400ms. To
change the delay perform the following steps:
Note: When the Lipsync problem is with a single
source component or between several compo-
nents in a system the MX151 Setup Mode allows
storing the correction into memory. Refer to
page 29 “Zone A Source Setup” or “Advanced
Audio Setup”on page 31.

Power Amplifier Meter Lights

Surround Mode
The MX151 provides five different default Surround
Modes and up to sixteen assignable Custom Surround
Modes. The MX151 Signal Processing Circuitry first
looks at the incoming audio signal and determines if
the signal is two channel or multichannel (more than
two channels). The incoming signal will be processed
depending on the MX151 Surround Mode setting.
When the MX151 is in the “No Processing” Surround
Mode, the incoming signal format determines how the
signal will be processed. For example, if the incom-
ing signal is a Dolby Digital 5.1 signal the MX151 will
decode it into 5.1 audio. The chart below shows the
default processing applied:
