DJ Tips In Under A Minute: Start your RMX-1000 effects turned all the way up

May 20, 2017 by DJJay
All right. Little RMX tip for you, normally gauge your effect and you do a build. Then bring the effect down. But try this new noise, first, bring the engager knob all the way over, then bring in the effect and then drag the effect backwards. So again, bring it all the way up, bring in echo, then tail the echo back. But again, you'd want to bring this all the way up first, then engage the effect and then bring the effect down. It could be a really cool feature on the RMX, a really cool way to add a nice little effect tail, in under a minute. ... [read more]

A Primer on Digital Signal Processing

May 14, 2017 by Robert Lindquist
In the days of analog, loudspeaker cabinets contained two or three drivers, some baffles and a “carpet” covering. The amplifiers were mounted in a separate rack or built into the mixer, and the signal went straight from the outputs on the amp(s) to the inputs on the speakers. Signal processing was accomplished using separate, rackmounted EQs, compressor/limiters and other processing devices injected into the signal chain prior to the main amplification. It’s not like that anymore—at least not for most DJs. Coincident with the advent of powered speakers, Digital Signal Processing (DSP) has taken over the task of EQing or “tuning” loudspeakers to provi... [read more]

DJ Tips In Under A Minute: Guitarist Can Plug Into Your DJ Mixer

May 11, 2017 by DJJay
All right. DJ tips in under a minute. RCA to a 1/4-inch, just a cable, you've probably got them, you probably have one. It came in handy yesterday, because at the wedding I was performing, I had a guitarist and the guitarist showed up and looked at me and said, where's my amp? And I said, I don't have an amp. But fortunately, I know from experience that if you plug this into a guitar with a pickup and this into your mixer on the line, you can actually have the guitar play through your DJ mixer. I used a DJM-400 as a matter of fact, sounded great. Had to tweak the trim, had to tweak the channel, but sounded great. So it's one of those weird cables that sometimes you need to have, because you don't know what the outcome of the event might be or what you're expected to provide. So tips in under a minute, make su... [read more]

About Bose: A Brief DJ-Centric History

May 4, 2017 by Mobile Beat
Bose Corporation, founded in 1964 by Amar G. Bose, has many different divisions and specialty products, and holds patents for technology in home entertainment, automotive, military and many other areas; but when it comes to DJs, it's all about speakers and audio. While in the consumer audio arena Bose is well known for its Wave radios and industry-leading noise cancelling headphones, the company has been recognized as a leader in the professional arena as well. For most veteran DJs, their first encounter with the company’s unique take on live sound goes back to one speaker model: the Bose 901. The 901s were actually built for high-end home sou...

DJ Tips In Under A Minute: Speak To Any Music Vendor Who You Will Be Working With Before The Event

May 4, 2017 by DJJay
All right. DJ tips in under a minute. My last DJ tips was about a cable I used to have a guitarist plug into my mixer, because there was some communication breakdown where the guitarist brought one amplifier for the cocktail ceremony, but didn't have an amplifier for the ceremony. I was providing a microphone. So I could've gotten away with a mike stand, speaker stand and microphone, but as usual, I bring backups. So I brought a full system of two CD players and a mixer just in case and good thing I did, because guess what, the guitarist had to plug into the mixer. So I used an RCA line-in with a quarter inch to the guitarist. The point of this video is speak to vendors you're going to be working with. Maybe not the photographer, maybe not the florist, the cake, but if you're working with anybody that plays m... [read more]

Can you use a mic cable to run a DMX signal? The short, and only correct answer is “no”.

May 3, 2017 by Ben Stowe, CTS
Can you use a mic cable to run a DMX signal? The short, and only correct answer is “no”. Here are the physics. A DMX signal is a digital signal comprised of 1s and 0s being transmitted at a rate of roughly 250,000 per second. Each piece of binary data must remain legible to the receiving end, or the data is no longer useful. 1s must remain 1s and 0s must remain 0s, and they must arrive with the correct timing. Thus, a cable is designed with the electrical characteristics ideal for this type of signal (capacitance and impedance most notably) and it then must be properly protected with appropriate shielding. This does not mean that a DMX cable is superior and should then be used for both DMX and analog audio. Here again, analog audio cables are designed with the best set of electrical characteristics ...

Carvin: Sound, American-Style

May 3, 2017 by Mobile Beat
On a recent West Coast business trip I enjoyed a full tour of the Carvin headquarters, just outside of San Diego, CA. To put it mildly, I was impressed. I’ve done many tours like this, visiting manufacturers, distributors and dealers, and I always enjoy them. I like getting to know the people and the environments that they work in. Carvin is one of the very few music industry manufacturers who do almost all of their manufacturing in the USA, specifically in San Diego. The one small exception is some molded speaker cabinets, where just the cabinets are done overseas, then equipped with drivers, amps and more in San Diego. Carvin works with distributors ...
