For setting up your own channel output system, you can't beat this high-output modulator. The low-profile, crystal-controlled PCM-55 provides a modulated visual and audio RF carrier output on any single VFH(2-13), midband (A-I), or superband (J-L) channels. Also, the PCM-55 can be inserted on any unused channel within a closed circuit MATV or SMATV system.
