Airtight audio connectors for active loudspeaker manufacturers

October 12, 2012 // By Julien Happich
Cliff Electronics has released two innovative connector products which offer pro-audio manufacturers and live music producers solutions to longstanding problems. The family of airtight XLR sockets has been developed primarily for active loudspeaker manufacturers which are common in studio monitoring and similar hi-fidelity audio applications.

Air leakage from conventional connectors is recognised as an acoustic problem in high quality loudspeaker design, particularly the “infinite baffle” types often found in recording studio and broadcast applications. The airtight XLR connector family provides a cost and labour saving solution to possible air leakage affecting speaker fidelity. The new connectors are inherently gas tight and supplied with a flange sealing gasket which promotes an efficient seal between the flange and mounting panel further helping to seal the mounting holes. The units are designed for both front and rear panel mounting and are available in 3 pin horizontal PCB, vertical PCB and solder bucket versions. The company has also released the Cliffcon ¼” JumboJack Plug which provides stage performers a solution to the problem of connecting high-current carrying, large section audio cables to conventional ¼” audio jack plugs.

In many professional sound installations it will be necessary to link equipment with low resistance cables, e.g. amplifier to loudspeaker connection; such cables tend to have large cross-section conductors. The new Cliffcon ¼” JumboJack plug can accept cable diameters of up to 15mm while still allowing these large diameter cables to be connected to conventional ¼” jack plug contacts. The Cliffcon ¼” JumboJack is available with both straight and right angled robust ergonomic body shells ensuring easy handling and fitting of cables. Connection is via screw type cable clamps and features integral cable strain-relief grommet which may be adapted to suit the size of the cable diameter being used.
