The Model 8656-XEU-AM Scrambler
provides all of the features and
functions of the Model 8656-XEU-
AMC Scrambler plus it includes the
SoundProtect audio masking feature.
SoundProtect audio masking
provides a method to scramble or
fully block the audio programming
on scrambled channels. 

When a channel is scrambled by the
8656 XEU-AM and the SoundProtect

audio masking feature is enabled,
only authorized audio de-masking
capable  8600

X

HCT will allow the

audio to be heard by the subscriber.
When tuned to a SoundProtect audio
masked channel, “cable-ready” TV’s
or non-audio de-masking capable
HCTs will provide sound consisting

of either a 400 Hz tone, generated
internally by the Model 8656-XEU-
AM Scrambler, or an audio barker
provided to the rear terminals of the
scrambler by the Network Operator.
The audio barker can be
promotional/advertising information
or a local radio broadcast feed.

Only channels that need to have the
audio signal masked need to use the
Model 8656-XEU-AM Scrambler.
Non-audio demasking HCTs may be
used in cable networks which
employ audio masking; however,
these HCTs will not provide program
audio on the audio masked channels.
