5-input programmable amplifier with LTE filters Triax TMB300

€289.67 €459.80 Save 37%

The new programmable multi-band amplifier TMB 300 from TRIAX has all the necessary features to amplify and distribute a large number of terrestrial digital and analog signals in a network.

With a single unit, and by means of selective filters, you can combine and amplify terrestrial analog and digital signals.

The TMB 300 amplifier allows to receive these signals, to equalize their levels and amplify them. It can be used as an independent unit, as well as a part of a headend station where a channel expansion or a frequency modification is necessary.

The TMB 300 amplifier is equipped with 10 filters that can be distributed between the inputs UHF1, UHF2 and UHF3. The fi lters are adjustable and can be tuned in the channel range 21 ... 69. In addition, the frequency band of each fi lter can be programmed from 1 to 7 channels (from 8 to 56 MHz). The individual adjustment in each fi lter of the frequency, bandwidth and output level allows you to align the levels of the selected channels. From the UHF1, UHF2 and UHF3 inputs, 12V or 24V voltage can be supplied to the mast amplifiers.

The signals of BI-FM and BIII-DAB are similarly amplified.

Features

  • 10 adjustable fi lters from 1 to 7 channels
  • Easy to adjust
  • 5 Inputs: BI - FM, BIII - DAB, UHF1, UHF2 and UHF3
  • Switchable UHF gain of 50/40 dB
  • Gain BI - FM = 30 ± 3 dB
  • Gain BIII - DAB = 30 ± 3 dB
  • Output level UHF = 118 dBμV
