2. PRODUCT DESCRIPTION

Vestigial A/V modulators available in mono, stereo and multistandard versions. One modulator can cover the

full bandwidth, 47-862MHz. At the output, the level of the audio carrier can be regulated separately from the RF

level through the TPE programmer. Fully agile output modulator with double conversion, saw ﬁlters and tracking

ﬁlter built-in. Due to the saw ﬁlters the full bandwidth is available as there are no unwanted carriers.

Due to the tracking ﬁlter the noise in the band is very low so that it is possibile to use more than 80 modulators

in one headend with a ﬁnal C/N >47dB.

Inside the modulators box the following accessories are included:

KPR41 solid bridge used to mix in signals between different modules

RCA cable used to connect modulators to the source

On the front panel there are RCA connectors (A/V inputs) and F connectors (mix-in input and RF output modu-

lated channel see Fig.1).

If the Green LED is ON then the module

is powered. If the Green LED is blinking it

shows that the module has been selected to

be programmed.

If the Red LED is ON it means there is an

erro. Try to reset the module but if the pro-

blem persists the module needs to be chec-

ked and repaired.
