General description:
The Triax TMM 4x Multi Switch Series is a fully modular and cascadable system suitable for single- as well as multi-satellite configurations (up to 4 satellite positions: 4, 8, 12 and 16 polarities).
An individual 0 - 12 dB level attenuation on every polarity assures a uniform subscriber signal level independent upon floor and eliminates the need for many different types.
Suitable for installation on a mounting plate as well as wall-mounting.
Passive cascadable distribution in trunk lines: 4 satellite polarities.
TMM 4x are available in versions with 4, 8, 12 and 16 Subscriber Outputs.
Subscriber outputs are active to compensate for insertion-loss.
The TMM 4x Series can be used as stand alone, SAT-only, switches, and the 4- and 8- output versions are also suitable to build multi-position systems using TMM Bridger units.
In a multi satellite configuration the TMM 4x module can be placed as any satellite position because the TMM 2/3/4B Bridger units can take the terrestrial loop-through on any input.
