Sing along to your favourite music, hook-up the unit between your CD player, MD player or any other line-level source on the one hand and your amplifier on the other. RCA (cinch) input and output sockets with 6.35mm microphone jack, fits most microphones. Adjustable microphone level, "vocal reduction"-switch reduces original vocals on most stereo recordings. on/off switch and LED power indicator.

This unit allows you to control a relay by means of the well-known DMX512 protocol. This protocol was developed by USITT in 1986 to control dimmers, scanners, moving-head spots and other lighting devices with a simple wiring. In some cases, a simple ON/OFF selection is desired. This is where this VM138 comes in. It is actually a bus-controlled power driver. The relay will be activated when the DMX value of the set channel equals 140 or more and turns off when the value is 120 or less. Together with our K8062/VM116, a computer-controlled automation will be very easy to build.

Tests correct pin configurations of 10-Base-T (Cat 5), 10-Base-2 cable (coax), RJ45/RJ11 modular cables, 356A, TIA-568A/B and token ring cable systems. Remote cable tester unit can test cables installed up to 1000ft away either on wall plate or patch panel Easy-to-read display verifies cable continuity, open, short and cross-connect Comes complete with remote tester unit, RJ45 cable, RJ45 plug to RJ12 jack adaptor, 2 x BNC adaptor cables, BNC male - BNC male adaptor.

This LAN tester for various cable types is indispensable in network installation and maintenance activities. This compact device can be used for testing network or telephone cables (RJ45 (8P8C), RJ12 (6P6C), RJ11 (6P2C), RJ10 (4P4C)) and for most types of computer cables.

High quality replacement oscilloscope probe set with insulated BNC connector. A passive, high impedance oscilloscope probe designed and calibrated for use on instruments having an input impedance of 1Mohm shunted by 25pF. However, it may be compensated for use with instruments having an input capacitance of 10 - 35pF. The probe incorporates a two position slide switch in the head which selects attenuation of X1, X10 position.
