Why do you have to use the DMX terminator? A DMX terminator is an important part of any DMX DJ light system. If you find the DJ light switch off, flicker, change color, pattern, etc. That may be a sign that you need a DMX terminator! When no DMX terminator is used, the [...]
How to choose the right speaker wire/cable? The purpose of Speaker cable is the wire used for the electrical connections between amplifier sources and loundspeakers system.The transfer is accomplished through the low-voltage electrical current conducted through the wires.It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important [...]
What is the DMX512 lighting control cable (AES/EBU Digital audio Cable)? DMX cable signal is based on RS485 signal, a kind of industry-standard protocol after adjusting the transmit Baud rate. Usually there are one pair DMX512 lighting control cable and two pair DMX512 lighting control cable. Cable types that are appropriate for DMX512 usage [...]
What is the S-video and PS/2 port? S-video (short for Super-video) is an older type of video signal that’s transmitted in varying electrical signals over wires to represent the original video. Newer video cables like HDMI transmit digital video signals in the form of numbers representing the original video signal. The benefit of [...]
A DIN connector is an electrical connector that was originally standardized in the early 1970s by the Deutsches Institut für Normung (DIN), the German national standards organization. A DIN connector encompasses several types of cables that plug into an interface to connect devices. It has an architecture that is composed of multiple pins that [...]
DMX Termination DMX Termination with 110 Ohms Resistor "Open ends" of DMX lines must be terminated. The 3-pin terminating plugs contain a 110Ω, 1/2W, resistor across pins 2 & 3. and the 5-pin terminating plugs contain two 110Ω, 1/2W, one resistor across pins 2 & 3, another resistor across pin 4 & 5. The [...]
XLR connectors are used in audio (mic level & line level) and DMX lighting control (DMX) applications. 3-Pin XLR and 7-Pin XLR Audio Pinout The following is the AES industry standard for balanced audio XLR wiring, commonly known as "pin-2 [...]
The propaudio ultra low capacitance cable lets you hear all the frequencies being produced by your guitar. High cable capacitance kills the high frequencies from your pickups, resulting in a muddy sound and the greater the signal loss. With cables that are paired, or coaxial, the two conductors with insulation or conductor and shielding [...]
A Line level is in the region of 0 dBV (1.0 volt), Line level signals have a much higher voltage output than mic or instrument level, usually somewhere around 750 millivolts.It is about 1,000 times as strong as a mic-level signal, so the two do not ordinarily use the same input. This signal travels [...]
Some mixers and active speaker have switches on the rear panel for setting each input jack or output jack for mic level (XLR) or line level (1/4"). These terms refer to the signal level or intensity. Microphone level is in the region of -60 dBV (0.001 volt) to -40 dBV (0.010 volt). (dBu and [...]
