Radial Releases Updated SW8 Backing Track Switcher


RADIAL ENGINEERING has updated its SW8 backing track switcher with several new features and functions.


The SW8 is designed to switch eight audio channels simultaneously. Backing tracks are recorded on two separate systems and each is sent to the SW8 where the user may manually select between the playback systems or have the SW8 automatically switch between them when a dropout occurs via an internal gate. Inputs include a choice of quarter-inch


TRS or 25-pin D-subs. The outputs can be via a series of transformer isolated low-Z XLR outputs to run through a snake system or a D-Sub. New features include a


standby function that enables the technician to stop the show in between songs when the artist chooses to speak to the audience, and a global mute that turns off all outputs


Trio of new ranges for Mackie


MACKIE HAS announced three new product series, including additional loudspeakers for its SRM line, improved mixers, and new MRmk3 studio monitors. To its SRM powered loudspeaker line,


Mackie has introduced three 1,600W models featuring custom transducers within internally braced all-wood cabinets. There are two high- output full-range models – the 12in SRM550 and 15in SRM650 – plus the SRM1850 18in powered subwoofer. SRM features Mackie High Definition


Audio Processing including acoustic correction DSP plus system optimisation tools like application-specific speaker modes and a feedback destroyer. SRM’s integrated two-channel mixer with Mackie Wide-Z inputs can handle any signal. The new VLZ4 line analogue compact mixers include Mackie’s Onyx preamps and deliver high-headroom, low-noise analogue mixer design. The eight VLZ4 mixers replace the VLZ3 models. The VLZ4 line includes models ranging from the desktop 402VLZ4 to a choice of four-bus effects mixers perfect for touring live sound work.


VLZ4 models feature custom op-amps and negative summing bus architecture, a solid steel wraparound chassis, and grime- resistant sealed rotary pots.


www.audiomedia.com September 2013 9 The MRmk3 Powered Studio Monitor line


replaces the previous generation of monitors with the MR5mk3 and MR8mk3, and expands the range with the 6.5in MR6mk3 full-range monitor and MR10Smk3 studio subwoofer. A newly designed minimum-diffraction


waveguide provides transition from highs to lows and creates a wider sweet spot and an open feel. All MRmk3 cabinets are rear ported and packed with acoustic absorption material. The low frequencies can be boosted by up to 4dB and the highs can be both cut and boosted.


The MRmk3 Series also includes the MR10Smk3 Powered Subwoofer. The low-profile enclosure is rear-ported and features vibration-absorbing rubber feet. Optimising features include an adjustable crossover plus a polarity switch. www.mackie.com


allowing the tech to monitor playback tracks and prepare playback cue points. Two signal status LEDs have been added for both A and B playback systems providing visual indicators to show signal present. External remote control options now include either a footswitch or desktop option with LED status indicators. To help eliminate switching noise with less than ideal sources, a series of filters have been added on all channels. Gate level controls have also been relocated to the front panel for easier manipulation. www.radialeng.com
