MP24 DJ Mixer

General history

Rane first entered the DJ mixer market upon request from Richard Long of Richard Long & Associates (RLA). Richard Long was a famous sound designer for the biggest names in disco. He designed systems for Studio 54, Annabels (London), Regine's (a chain of 19 clubs scattered around the world from Paris and New York to Cairo) and many others that were the vanguard of the disco era.

Richard approached Rane and asked them to redesign his famous X3000 crossover using their proprietary technology. This became the X3000A, built exclusively for Richard Long. They also codesigned a DJ equalizer called the Q5000. Based on his successful relationship with Rane, he persuaded them to research the DJ mixer market. They did and produced their first DJ mixer, the MP24 which rapidly became the industry standard, installed in clubs around the world for almost 20 years.

Functionality issues on the MP24 series vary widely. The original MP24 did not have a switchable booth output ducker, nor could the output level be adjusted as much. These features received immediate attention. The MP 24x is the first version to use the VCA controlled Active Crossfader assembly. The "x" and "z" type crossfaders are not interchangeable. See the Crossfader Replacement Chart for applications and part numbers. The "constant power" (dip in the middle) crossfader circuit cannot be changed to that used later in "z" version.

Manuals for all three models are available from the Downloads link.

Interesting things MP24 mixers have done or been exposed to

An MP24 came in with a bullet hole in its rear chassis once, from a .22 going off in a night club. It still worked when it arrived.

We got a mixer back that had been smashed repeatedly (read fit of rage) with a crowbar. Although the front panel was very bent the mixer worked, the faders were difficult to adjust.

A guy tried to fix a hum in his sound system using a "cheater adapter" on his MP 24 line cord; the channel four circuit board melted and the mixer was destroyed. He later found out the club had "improper" AC wiring. Ya think?!

The MP24 is the longest continually produced DJ mixer on the planet. The UREI 1620 had the record for many years. First MP 24 shipped September 8th, 1986; it's serial MP1002.

A customer stripped his older color front panel down to bare metal, had it re-painted black then paid substantial money to have it re-silk screened. Over five years later Rane changed all products to black color. Maybe this guy was clairvoyant.

On more than one occasion, an MP24 has frantically been shipped back to the factory after champagne spilled in it -- must have been a festive wedding reception -- just to arrive "dried out" and functioning correctly. We cleaned and tested each of them, just to be sure.

A few MP24s have survived automobile accidents, with damage ranging from sheared front panels, to almost every control snapped off. We've been able to successfully restore all subjected to this torture, so far.

The first MP24 was originally designed for broadcast and production applications, not club installs. We designed it "so sturdy," becoming the industry standard was to be expected.

The last MP 24z was built and shipped on July 31, 2006. It didn't quite make its 20th birthday. Its demise came from lead-free solder requirements in the EU. Existing MP 24s will continue to entertain for many, many years.
