Bell& Howell
The DEMAM-9S A183 part is an A/V signal monitor from ITT Bell & Howell that is designed to detect and monitor composite A/V signal faults in a variety of formats, including PAL, NTSC, and SECAM. This monitor is capable of receiving signals from a signal source, such as a cable line, satellite dish, television transmitter, or other A/V device, and can present the user with a visual and audible alert when it detects problems. The DEMAM-9S A183 includes an Audio Loudspeaker, allowing for the quick identification of audio problems. It also includes a Video Frequency Meter, allowing for fault-finding when it comes to video signals. The unit is housed in a compact and rugged Plascosel-clad steel case, making it well-suited for harsh environments. Additionally, the monitor can be equipped with a thermally-protected A/C power receptacle, making it compatible with most countries' power systems.
