IKUSI Quad A/V to DVB-T Modulator

MAC-401 Quad A/V to COFDM ModulatorProduct overview :For the first time! A solution for the AV input problem in an all digital world. The MAC-401 has been specifically configured into a low cost stand alone case designed for the purpose of converting existing A/V outputs from analogue sources into a ‘Freeview’ compatible digital multiplex.The MAC-401 works by offering the incoming A/V signals into an MPEG-2 encoder whereby the signals are converted into a digital bit stream. This is modulated into a COFDM multiplex occupying an 8MHz bandwidth.With an onboard LCD programmer or via a conventional PC or laptop (using web browser), our simple menu based setup screen allows the titling and channel numbering with a whole host of extra features, such as channel tuning and level adjustment.Specifications :InputVideo: 4 x CVBS (composite)Video input level: 0.7…1.4VppVideo input codifications: PAL/NTSC/SECAMAudio Input: 4 x mono/stereoAudio input level: 0.5…4Vpp (RCA cx)Connectors: RCAProcessingAudio compression: MPEG 1 layer IIVideo compression: MPEG2 MP@MLMaximum resolution: PAL 720x576@25fps; NTSC 720x480@30fpsQuality: DVD Full D1Insertion of PSI/SI tables: PAT, PMT, SDT, NIT, TDT, TOT, EITLCN processing: YESEditable Channel and Info titles: YESOutputOutput standard: ETSI EN 300 744 (DVB-T)Carriers: 2K, 4K, 8KOutput format: QPSK,16QAM, 64QAMGuard intervals: 1/4, 1/8, 1/16, 1/32Code rate: 1/2, 2/3, 3/4, 5/6, 7/8Output frequencies: 51…858MHzOff set frequency steps: Down to 1kHzChannel bandwidth: 6, 7, 8MHzMaximum output level: 80 dBµVOutput attenuation: 0…-15dBMER (typical): 38dBGeneralVoltage: 230-240VacPower consumption: 0.45A / 30WTemperature range: 0…+45ºCWeight: 2.5kgDimensions: 302x251x44mmInterfaceStandard: Ethernet 10Base-TLocal interface: LCD + joystickRemote interface / updates: Web / Ethernet
