Cable Clarity: DMX & Mic Cables

From time to time, the question always rears it’s ugly head…”Can I just use microphone cables in place of DMX cables for our stage lighting?” The answer is that you really shouldn’t.

While both DMX and microphone cables share 3 pin XLR connectors, the cables themselves are two different beasts. Aside from being labeled as DMX cables and having a somewhat less rugged construction than most mic cables commercially available (not as thick or flexible in most scenarios), DMX cables pass signal through substantially higher impedance than microphone cables. Most DMX operate at 110-120 ohms while mic cables are typically 60-70 ohms.

In many ways, cable is like a hose, and signal is like water flowing through it. By decreasing the impedance (using a mic cable for lighting) is like making the hose wider in diameter. We are then faced with a situation where our output of water is no longer adequate to push the data through the hose at the appropriate speed. This mis-match can result in flickering lights, mis-que’d controllers, and damage to gear or blackouts. All things that should never happen when you’re on stage.

Hopefully this information has helped you see the light and you’ll use the right cable for the job. Call us with questions or for more clever puns anytime.

600 MHz Bandwidth Changes

The FCC has recently ruled that the 600MHz-700MHz broadcast spectrum will be allocated for telecommunications use in 2016. This means that any wireless devices operating in that range will need to be decommissioned to make room for the companies purchasing the spectrum.

In 2008 the FCC auctioned off the 700MHz range (698-806 to be precise). Part of the logic behind this transition is that because digital television broadcasts use less bandwidth, there is free space available to re-purpose for new technology. The auctioning of the 600MHz range is the next phase in the FCC’s upgrade plan.

While this is all a step in the right direction for the “big picture”, it will cause severe inconvenience to facilities that rely on devices operating in the 600MHz range. Some examples include:

 SHURE PRODUCTS using the L4 range (638-662) 

SENNHEISER PRODUCTs using the B range (606-774)


Most operating ranges can be found on the back of your wireless receivers. Several manufacturers are offering incentives to replace your old wireless gear at a reduced price or providing refunds for returned “obselete” products.

If you would like to know what your options for updating are, give us a call anytime at

206-285-7767  or email   info@avlprofessional.com

and we’d be happy to help make the transition as simple and affordable as possible.
