    For applications that typically require a throw between 15-30m, a full-blown line array is not always practical, optimal or affordable. Conversely, a point source solution may not be sufficient in coverage and SPL. TORUS is a constant curvature array, designed to fill that gap perfectly, combining optimised coverage, SPL and cost efficiency.

  • Page 6: System Overview

    System Overview TORUS TORUS arrays are created using the two models in the series; the T1215 and T1230. Both feature a single 12” (300mm) Neodymium magnet low frequency drivers which are phase plug loaded for increased mid-band sensitivity. The high frequency element comprises three 1.4” (35mm) Neodymium Polymer Dome compression drivers loaded with a manually adjustable Dynamic Horn Flare offering horizontal dispersion options of 60°, 90°...

    The horn is adjusted from the front of the cabinet. This is done without the need to remove the grille. Landscape Deployment TORUS combined in landscape creates a vertical array. In this mode the combined fixed angle of the cabinets becomes the vertical dispersion, and the flexible dispersion can be adjusted in the horizontal.

  • Page 8: Portrait Deployment

    TORUS USER GUIDE Portrait Deployment TORUS combined in portrait creates a horizontal array. In this mode the combined fixed angle of the cabinets becomes the horizontal dispersion, and the flexible dispersion can be adjusted in the vertical. Changing Horn Dispersion To adjust the angle, rotate the thumbwheels at the top and bottom of the grille.

    T12PB The T12PB allows up to 6 x TORUS to be flown in vertical arrays without any array angle limit. It can also be used as a pullback/array stabilizing accessory when used with a T12GRID. TORUS USER GUIDE V1.0...

  • Page 11: Recommended Subwoofer

    Whilst a TORUS array can be complimended with any of the SX Series subwoofers, the SXCF118 is an idea choice for vertical TORUS arrays where a flown subwoofer is required in a combined array. By using the T12TRIG, TORUS can be flown directly under an array of SXCF118 subwoofers.

  • Page 12: Amplification

    For the best possible performance T1215 and T1230 are powered and controlled using iKON amplifiers. Presets are dynamically created using Martin Audio’s DISPLAY 3 prediction software. Once optimised the parameters can be exported from DISPLAY 3 and uploaded to the iKON amplifiers via VU-NET control software.

  • Page 13: Display 3.0

    DISPLAY 3.0 Overview DISPLAY 3 is modelling software that predicts coverage and SPL for Martin Audio loudspeakers in a 3D environment. Optimised Array, Constant curvature, point source and subwoofer solutions can be reviewed, and system designs validated. Within the application, venue creation is achieved via an import from Sketchup or by extruding a 2D slice from Display 2 software.
  • Page 14 The auto-assign button in the coverage tool automates this process. Loudspeakers are inserted from the loudspeaker library or imported from a Display 2 file. TORUS constant curvature systems for example can be deployed horizontally or vertically, with cabinet type, quantity and horn angle defined from the loudspeaker inspector menu.

    EQ routing and delay via a networked infrastructure. Devices can be added manually using the Palette on the left, but this has limited use. In practical applications, the Discover Devices button is used. TORUS USER GUIDE V1.0 Copyright © 2021 Martin Audio Ltd.
  • Page 17 The application searches the network for all Vu-Net enabled devices and will add them to the project upon discovery. Presets are added to the amplifiers using the preset manager. Right click an amplifier to access the preset manager. TORUS USER GUIDE V1.0 Copyright © 2021 Martin Audio Ltd.
  • Page 18 TORUS USER GUIDE When loading a TORUS T12 preset, first select the deployment type, followed by the number of speakers and amplifier channels used to drive the array. The preset info box displays a coloured graphic of the T12 array showing how it should be wired. For vertical systems, the array is wired from top to bottom and for horizontal systems, it is wired from the centre out.
  • Page 19 For horizontal arrays, only one DSP channel is required. TORUS cabinets have an LED for identification, this can be toggled from within the amplifier’s control panel. The output channel is muted to prevent audio from passing to the circuit when the LED is active.
  • Page 20 PEQs and the Lo-Shelf are ganged across all used DSP channels in the array, whereas the FIR Hi-shelf is independent for each DSP channel. The high-pass filter is available on the Output EQ section for use with a subwoofer.

    TORUS USER GUIDE Rigging Overview TORUS consists of a single-point rigging system located on either side of the cabinet, all hardware is captive and can be stored conveniently for transportation. Link Link Link Pin The fixed angled enclosure can be arrayed vertically and horizontally and deployed in various configurations with additional hardware.

  • Page 23: Inclinometer Assembly

    Inclinometer Assembly Martin Audio supplies an optional remote angle monitoring system which can used to check the tilt angle of the array. It consists of a sensor (mounted within the flying frame) and a remote display unit. Interconnection is via a standard XLR mic cable.
  • Page 24 The sensor can be fitted to both sides of T12GRID and various orientations allowing to be used for every array configuration Note that a single inclinometer reader can be used with multiple sensors. It is not necessary to have the same number of displays as sensors. TORUS USER GUIDE V1.0 Copyright © 2021 Martin Audio Ltd.
