  • Page 4: Declarations Of Conformity

    DECLARATIONS OF CONFORMITY This declaration applies to: 10M604 – R12 compact 3-way precision passive point source loudspeaker This declaration also applies to all product variants, provided that they conform to the original technical specification and have not been subject to any non-factory modifications.
  • Page 5: Introduction

    Two waveguides are supplied with the R12 - 80° x 50° fitted as standard and 110° x 50° supplied loose. These three drive units are linked with a completely new type of passive crossover network, designed from the ground up to work in conjunction with the FIR (Finite Impulse Response) processing in the DQ Series advanced system amplifiers.

    NET/SHIPPING WEIGHT: 42/49.9kg (92.4/109.3lbs) FC-R12h The FC-R12h is a simple and effective means of mounting the R12 horizontally Horizontal flying cradle in both temporary and permanent applications. It is secured to the cabinet by means of two M10 hand knobs into the top and bottom of the loudspeaker to mount it in a landscape format.
  • Page 7: Fc-R12V

    Page 7 of 35 FC-R12v The FC-R12v is a simple and effective means of mounting the R12 vertically in Vertical flying cradle both temporary and permanent applications. It is secured to the cabinet by means of a quick-release keyhole plate in the top of the loudspeaker to mount it in a portrait format.
  • Page 8: Determining The Installed Waveguide And Orientation

    110° x 50° horn is fitted and is oriented so it is 50° in the vertical plane (and therefore 110° in the horizontal plane). By default, the R12 ships from the factory with the 80x50 waveguide fitted, and the dispersion pattern 80° horizontal x 50° vertical when the loudspeaker is in a portrait format.
  • Page 9: Rotating The Mhf Waveguide

    Page 9 of 35 2.2 – Rotating the MHF waveguide The high frequency waveguide of the R12 can be easily rotated to provide appropriate dispersion in both portrait and landscape formats. By default, the R12 ships from the factory with the dispersion pattern 80° horizontal x 50°...
  • Page 10: Changing The Mhf Waveguide

    Page 10 of 35 2.3 – Changing the MHF waveguide The R12 is supplied with two waveguides for maximum flexibility – a narrow dispersion (80° x 50°) and a wide dispersion (110° x 50°). By default, the R12 ships from the factory with the dispersion pattern 80° horizontal x 50°...

    Tutorials for Ease Focus 3 are available from with the application itself. For training on the design and implementation of R12 loudspeakers including the specific use of Ease Focus 3, please contact your local distributor.
  • Page 12: Safety Considerations

    General Considerations in use Loudspeaker systems are potentially dangerous objects if used incorrectly. Please ensure that you read this section fully, and contact EM Acoustics or your local dealer should you be in any doubt over correct operation procedures. Personal Injury Never stand in the immediate vicinity of loudspeakers when in use at high level.
  • Page 13: Ground Stacking

    EM Acoustics is in no way liable for any loss, damage or injury caused by such practice. Do not modify or alter the R12 loudspeaker or accessories, nor use them in any way other than that described in this manual. Rigging components supplied with the R8 are in no way interchangeable and should not be used as such.
  • Page 14: Secondary Safeties

    In most cases, annual independent tests & inspections carried out by a suitably approved and qualified inspector will be required. EM Acoustics recommends detailed logbooks be kept of all inspections and load tests to ensure an accurate record is kept of the testing for each EM Acoustics rigging accessory.

  • Page 16: Using The Fc-R12V

    Page 16 of 35 5.2 – Using the FC-R12v The FC-R12v is intended to mount the R12 vertically – using a hook clamp or similar from above. The procedure for attaching the FC-R12v to the loudspeaker is the same regardless of the mounting orientation.
  • Page 17: Using The Fc-R12H

    Page 17 of 35 5.3 – Using the FC-R12h The FC-R12h is intended to mount the R12 horizontally. To fit, lie the R12 on its side and line the flying cradle up with the mounting holes in the desired location (see 5.3.1 below).
  • Page 18: Using The Vfa-R12

    The VFA-R12 is a single-point suspension bracket, designed to support a single R12 loudspeaker and uses the R12’s centre of gravity to determine the up or down-tilt angle. In this way, angles from 20 degrees up-tilt to 30 degrees down-tilt can be selected in 2.5- degree increments.
  • Page 19: Angle Adjustment With The Vfa-R12

    The angle that the R12 will hang at depends on the pickup hole selected. The 9 hole back from the front will hang the R12 flat, all other holes will increase the angle in 2.5-degree increments. In this way, the front hole will provide 20° of up-tilt, and the furthest back hole will provide 30°...

    6.1 - Amplifier and Processing Requirements 6.1.1 - Connections The R12 requires only a single amplifier channel. Inputs to the R12 enclosure are on Neutrik SpeakON NL4 as illustrated below. Two-core cable should be used for connecting R12 loudspeakers, and the connections are...
  • Page 21: Amplifier Requirements

    R12 loudspeakers is not recommended. 6.1.4 – Processing Requirements Whilst the R12 is a passive loudspeaker, it is designed to be part of a system in conjunction with a DQ or Di Series amplifier. These intelligent amplifiers provide not only protective settings to prevent damage to your R12 loudspeaker, but also makes use of the state-of- the-art Finite Impulse Response (FIR) processing.
  • Page 22: Presets And Settings

    6.2 - Presets and Settings 6.2.1 – Standard R12 presets When used with a DQ or Di Series amplifier R12 loudspeakers require only a single amplifier channel, and as such the preset recalled will only require one output from your DQ Series amplifier.
  • Page 23: Use With The Dq Series Advanced System Amplifiers

    6.3 - Use with the DQ Series Advanced System Amplifiers The R12 is designed to be used with DQ or Di Series advanced system amplifiers, as not only are they state-of-the-art amplifiers, but the onboard DSP provides appropriate processing to allow the R12 to perform as intended.
  • Page 24: System Connectivity

    Because pins 2+/2- are linked through inside all EM Acoustics loudspeakers, using a 4-core cable to one loudspeaker (carrying two different signals) allows a crossover cable to be used to link out of the first loudspeaker into another, thereby feeding it from a separate signal.
  • Page 25: Servicing Information

    To replace the grille, position the grille on the front of the R12 and ensure the threaded fittings on the grille are lined up with the mounting holes – gentle pressure may be required. Replace all of the M6x30 countersunk socket screws and ensure they are all are started in their threads before beginning to tighten.
