Programmable Filter Amplifier -6611
Features:
Multi channel programmable filter-amplifier. 4 inputs : B I-FM , B III / DAB and 2 UHF inputs splitted over 6 UHF programmable clusters UHF clusters can have 1 to 7 channels bandwidth B III/ DAB input with 1 or 4 channels bandwidth filter. Designed for both digital and analogue channels Easy programming by using one rotary / push button viewed on 2 digits display and LEDs for each cluster and each input Unit can be locked by security code. 'Copy' function in order to transfer all settlements from one unit to another reducing time of installation High selectivity filters. Low noise and high gain split band amplifiers. High UHF input levels up to 105 dBµV by switchable 20 dB input amplifier. Attenuators with 1 dB step for accurate equalization. Selectable remote power on B III and UHF inputs 12 - 24 V selectable remote power.| Reference | 6611 | |||
