With different amplifier series POLYTRON has the perfect solution for any situation. From small apartment buildings to large distribution networks – POLYTRON amplifiers convince with reliable electrical values and long durability.

Special details are the excellent amplitude frequency response and the adaptable equalisation and attenuation parameters. Flexible return-path concepts round off the amplifier profile.
The die-cast housing is a standard feature and completes the quality concept of POLYTRON amplifiers.

All POLYTRON amplifiers fullfill the high demands of Class A.

By using the set-point-bridges, you can adjust attenuation or equalization in 1 dB steps.
The set-point-bridges can be ordered individually, in 10 piece packs or in a service-box.

Service-box 1: VSP-1/ 3/ 5/ 7/ 9/ 11/ 13/ 15/ 17/ 19 dB – 5 pieces of each type.

Service-box 2: VSP-2 / 4/ 6/ 8/ 10/ 12/ 14/ 16/ 18/ 20 dB – 5 pieces of each type.

Due to the available selection of splitter and taps the configuration of the outputs (line out, output 1, output 2) is flexible.

Return path modules are available as active version (with amplification) and  as passive version (without amplification).

The AGC regulation module VMC 05 – applicable in all CV and HV amplifiers – uses the sum level of the CATV system to regulate the level.
A pilot tone generator is not necessary. For levelling the AGC module, the setting module VMC-E is required.

Diplex filters split the forward and return path for separate amplification.

The attenuator module decreases the amplification and the output level up to -20 dB.

The service module for return path measurements is used instead of the diplexer at the amplifier output.
