1Soundlab active audio splitterSoundlab Electronics have releasedthe AS1 active audio splitter. Builtto IRT specifications, the AS1 is amodular system each module housing10 input channels, all split to threeoutputs. Each input has lockableswitches for phantom power and18 dB of gain and is balanced andearth -free.A full range of options is availablefor the system including racks, flightcases and an input /output panel withCannon and Siemens multipins formulticore cables. An elaborate earthlift facility is also incorporated.Soundlab Electronic, RobertBosch Strasse 34, 8044Unterschleissheim, West Germany.Tel: 089 3.10.30.01. Fax: 0893.10.20.70.SCV dynamics controller andSR control unitThe AT422 is a dual 4-banddynamics controller and the PSDDirector is a control unit for soundreinforcement systems.The AT422 is designed forapplications such as FM and stereotelevision broadcasting, CDmastering, post -production and highquality sound reinforcement andconsists of a dynamics controllerwhere each channel is split into fourfrequency bands, each with its ownlimiter /compressor /gate.It employs low distortion VCAs andultra low -noise ICs and featuresselectable pre /de- emphasis, outputgain, stereo coupling and vu/peakmetering. An elliptical equaliser formodifying the stereo image is alsoincorporated as is a soft -clipper -orpeak suppressor -on the final outputmix in order to prevent uncontrolledtransients reaching the followingequipment.Other facilities include LEDbargraph metering for input /outputlevels and gain reduction, electronically-balanced inputs and transformerbalanced outputs, RF protection andmomentary individual setup/bypassswitches for calibration.The PSD Director provides centralcontrol for sound reinforcementsystems with left, right, sub -bass andcentral cluster feeds. The cluster andsub -bass outputs can be sourced fromthe mixing console or derivedinternally in the unit via monosumming techniques and 4th orderLinkwitz -Riley filtering. In addition,the sub -bass channel can be switchedto full -range to provide an auxiliaryfeed for delay systems, etc.The PSD features ellipticalequalisers for stereo imageprocessing, LED bargraph meters foreach section (input or output levels),phase correlation indicators, ±12 dBof gain control on the cluster andsub -bass outputs, insert sends andreturns, secondary outputs with earthcompensation for connection to OBtrucks, recorders, etc, electronically -balanced inputs and transformer -balanced outputs.Other facilities include anadjustable interstage peak suppressorfor the sub -bass output and a testsignal for each section consisting of asingle octave tone sweepable through100 Hz to 10 kHz.SCV Audio, 186 Allee des Erables,BP 50056 Paris Nord II, 95947Roissy Charles de Gaulle Cedex,France.

The enclosures house a pairof 12 inch (2204H), 15 inch (2225H)and 18 inch (2240H) speakersrespectively for -3 dB points of35 Hz, 30 Hz and 28 Hz.The systems are designed for bothtouring and fixed installationapplications and feature both CannonEP-8 male /female connectors andXLR-3F connector.Also new from JBL are four horn/In briefThe Analog Digital SynergySynergy One digital console (StudioSound February 1988) is now inproduction and a fully working modelwas demonstrated at the HamburgAES. Based on the in -line mixingformat the console provides 4 -bandparametric EQ, high and lowpassfilters and two stereo aux sends.Each channel has its own statusdisplay for remaining headroom,overload and grouping and truedigital 100- segment bargraph PPMmeters are provided for all inputchannels and output buses. It isavailable in frame sizes of 16 inputs(up to four groups), 36/64 inputs (upto eight groups) and will accept alldigital formats but these must bespecified at the time of order.The NumeraiABAC digitally -controlled console is now inproduction and several pre -productionunits are already in use with FR3television in France.compression driver mounting systemsfor horn mounting on a flat surface.The 2506A fixed- position bracket isfor use with 2360 horns in JBLtheatre systems and the 2508A fixedposition bracket for 2344A12370A/2380 series horns.The 2507 3 -way adjustable bracketis designed for the 2344/2370A biradialhorns and the 2509 3 -waybracket for the 2360/2380 bi- radialhorns.JBL International, 8500 BalboaBoulevard, Northridge, CA 91329,USA.

Theaudio racks can be remotely installedat 50 m from the control unit bycable or at 800 m with a fibre -opticlink.The console is completelyautomated with a maximum timelength of 90 min. Data can bedownloaded to a tape streamer inapprox 4 min. The system can also besynchronised to SMPTE timecode.The configuration of the console isuser -programmable and setups can bestored and recalled as required.Numera, 11 rue Primatice, 75013Paris, France.
