      Rolls HR78X Digital 1/2 Rack AM/FM Tuner With XLR Outputs

      The Rolls HR78X is a PLL synthesized digital AM/FM tuner in a feature-packed half-rack chassis. The unit is ideal for replacing analog tuners, and where a small digital tuner is desired. The unit ships with FM and AM antennas, and the 1/8" output has sufficient levels to drive a pair of headphones. Up to two HR78X units may be rack mounted in a single, standard 1U rack space, the Rolls URT5 (Universal Rack Tray), or the RMS270 Rack Module System.

      • Retains presets when power is off.
      • 20 presets, 10 F

    • Channel Plus 2503-10 3Db In line Attenuators (10 pack)

      Channel Plus 2503-10 3Db In line Attenuators (10 pack)

      ChannelPlus in-line attenuators can be inserted in coaxial cable feeds to reduce signal amplitude levels. The model 2503 provides a 3dB insertion loss, and the model 2506 provides a 6dB insertion loss.

      • Reduces signal strength 3 dB
        Type F barrel connector
        Combinations of 2503s and 2506s may be used together to create attenuators with greater insertion loss
        These attenuators provide a better, more permanent solution over using a variable attenuator

      RF Attenuators

      RF attenuators are electronic devices which reduce the amplitude or power of a signal without causing a big distortion to its waveform. RF attenuators are the opposite of an amplifier. While an amplifier provides gain, RF attenuators provides a gain less than 1, or a loss. RF Attenuators are passive devices which are made using simple voltage divider networks. It is a circuit which suppresses or opposes a specific frequency band and is used for filtering and reducing noise in a circuit. Radio frequency or RF attenuators are coaxial in structure. Attenuation is expressed in decibels of relative power. Now that you know all about RF attenuators you can grab a bunch online at Markertek!
