MAIN AMPLIFIER DSP15-5G MAIN AMPLIFIER

Programmable DVB-T/T2 channel filter-amplifier

Programmable, compact amplifier for channel-specific filtering or channel switching of DVB-T/T2 signals. The device features a built-in 5G SAW-LTE filter to prevent mobile frequencies from entering the amplifier and distribution network.
Thanks to its output level, the DSP15-5G is ideally suited for small and medium-sized antenna networks, such as single-family homes, twin houses, and small to medium-sized apartment buildings.
No separate programming devices are required, as the DSP15-5G can be programmed via a smartphone using the LEM NFC app.

Features:

• 4 inputs and 1 output
• Programming/configuration via LEM NFC app (Android/iOS)
• 5G SAW filters against LTE interference
• Real-time, automatic gain adjustment in each filter
• 32 high-selectivity digital filters
• DC remote power supply via coaxial cable (MATV OUT)
• Zamak housing ensures high RF emission tightness
• Internal 230 VAC power supply
