TECHNICAL CHARACTERISTICS TECHNICAL CHARACTERISTICS

• 1 Video and up to 4 Audio. The MVL Series microwave links are designed to carry 1 video and up to 4 highquality 15 kHz analog audio programs. • Digital audio compatibility. The audio channels are fully compatible with the DB digital audio codecs TD/16 and RD/16. • Outdoor or Indoor RF converters. The RF up-converters (HMT) and down-converters (HMR) can be fitted into the microwave feeder, or to be fixed to a tripod head for portable applications. In alternative an indoor version

channel selective filters in the IF repeater unit allow to clean the received spectrum from any interference for a good repeater working also in congestioned RF spectrum conditions. The repeater assembly includes a specific indoor power supply unit (AL/HM). • Synthesized RF channels. Easy and fast RF frequency channel setting using a 125 KHz step digital low-noise PLL oscillator. • Data channel. High capacity data channel is available using the baseband in/out facility or a dedicated data transfer sub-carrier. • Instant installation. With the DB parabolic antennas family the tower or pole mounting becomes extremely easy, thanks to universal clamps with horizontal and vertical fine adjustments and V/H polarization shifter. • Full monitoring. A front panel digital multimeter complete with alarm leds allows to check the audio and video levels, RF output power, RF received level, PLL lock and the squelch status. • Meets or exceeds all the international standards for safety and electrical specifications.
