Details
The ma400 R82520 amplifier is a top-class device designed to amplify signals from the FM, VHF and UHF bands. Such signals can then be distributed in large, collective terrestrial TV installations - in multi-family buildings, hotels, public facilities, etc. The high output level of 118 dBuV and a gain of 30dB allow even the largest projects.
The amplifier is equipped with three potentiometers allowing to reduce the signal level in each of the three bands. In addition, it is possible to quickly, precisely attenuate the signal by 10 dB thanks to additional switches.
The ma400 amplifier has the ability to power antenna preamplifiers (in each path). It is powered by 12 V itself with a current consumption of 0.48 A. A single amplifier can be powered from any power supply with the specified current capacity and output voltage. We recommend powering a larger number of units from the dedicated DR-60-12 R82532 amplifier.
The unit can be installed on a wall (with the wall mount), or placed on universal DIN rail R82538 in a 19" RACK cabinet.
Key features:
- three independent amplifier circuits for FM, VHF&DAB, UHF
- separate inputs
- separate stepless gain control -15...0 dB
- separate -10/0 dB attenuators
- separate power supply for preamplifier DC 12 V 0.1 A
- 30 dB gain
- maximum signal level IMD3 VHF 116; UHF 118 dBμV
- DIN rail mounting, also for 19" rack mounting
