Introduction

TORUS

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.

T1215 offers a narrow vertical pattern of 15° with a ﬂexible horizontal pattern that can be manually adjusted between 90°, 60° or 75°

(Asymmetrical) via the Dynamic Horn Flare™.

T1230 offers a vertical pattern of 30° with a ﬂexible horizontal pattern that can be manually adjusted between 90°, 60° or 75° (Asymmetrical)

via the Dynamic Horn Flare™.

Important Safety Instructions

Please read these instructions and retrain for future reference. Heed all warnings and follow all instructions.

• No naked ﬂame sources such as lighted candles should be placed on the apparatus

• Do not block any ventilation openings

• Install in accordance with the Martin Audio instructions

• Do not install near any heat sources such as radiators, heat registers, stoves or other such apparatus that produce heat

• Do not defeat the safety purpose of the grounding-type plug. A grounding plug has two blades and a third grounding prong. The third

prong is provided for your safety. If the provided plug does not ﬁt your outlet consult an electrician for replacement of the obsolete

outlet.

• Protect the power cable from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit

from the apparatus

• This equipment must be earthed

• Only use attachments / accessories speciﬁed by Martin Audio

• Use only with wheelboard and rigging hardware speciﬁed by Martin Audio. When moving using supplied wheelboards, caution should

be used to avoid injury from the cabinet tipping over

• Unplug this apparatus during lightning storms or when unused for long periods of time

• No user serviceable parts inside, refer servicing to qualiﬁed service personnel. Servicing is required when the apparatus has been

damaged in any way such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus,

the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped

• Do not remove covers

• Do not remove any protective earth or signal cable shield connections

Unpacking the Units

After unpacking the unit, please check it carefully for any damage. If any is found, immediately notify the carrier concerned – you, the

consignee, must instigate any claim. Please retain all packaging in case you need to return the unit.

Please consider the environment. When the product has reached the end of its useful life, please dispose of it responsibly through a

recycling centre.

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 FlareTM offering horizontal dispersion options of 60°, 90° or 75° Asymmetrical.

The two models differ only in their vertical dispersion. The T1215 has a 15° vertical dispersion, the T1230 has a 30° vertical dispersion.

TORUS is extremely versatile and is suitable for short to medium throw applications with comprehensive rigging offering solutions for a

huge variety of coverage requirements to meet virtually any shape of venue.

Mechanical Design

TORUS enclosures are built from marine grade plywood ﬁnished in hard-wearing, water resistant PU paint. Ergonomic handles make for

ease of transportation and deployment.

The rigging allows for up to 6 cabinets to be ﬂown in a horizontal or vertical conﬁgurations and arrays can comprise of both models to tailor

the coverage to meet the requirements.

When ﬂying TORUS vertically the HF horn can be positioned on the left or the right to create symmetrical system design.

TORUS USER GUIDE V1.0

TORUS USER GUIDE

In a horizontal array the HF horn can be positioned at the top or bottom of the array.

Acoustic Design

TORUS low frequency section consists of a 12” (300mm) neodymium driver in a ported reﬂex conﬁguration to maximise low frequency

extension. The driver is ﬁtted with a phase plug in front of the cone to increase mid-band sensitivity to enhance projection in the vital vocal

band of frequencies.

The HF section consists of 3 x 1.4” (35mm) exit neodymium compression drivers mounted on a Dynamic Horn Flare™ with a ﬂexible

pattern control that can be manually adjusted between 90°, 60° or 75° (Asymmetrical).The system moves and locks the waveguide whilst

also adjusting the horn mouth including the low diffraction termination into the bafﬂe which ensures that the horn geometry remains

correct to produce the optimum settings for the dispersion you have selected.

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.

TORUS USER GUIDE V1.0

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. Each side is adjusted in 15° increments showing either

“45°” or “30°”. If both sides are at their widest position the total dispersion is 90°, by adjusting one side down by 15° from 45° to 30°

the dispersion will be 75° asymmetrical with a bias to the left or right depending on which side of the horn you have adjusted. With both

set to the minimum angle the dispersion reverts to a symmetrical 60° Indicators on the thumbwheels show which angle the horn is set to.

Accessories

T12POLERIG

The T12POLERIG allows a single cabinet (T1215 or T1230) to

be mounted using a standard 35mm speaker stand or a 35mm

distance bar when used in conjunction with one of the SX Series

Subwoofers ﬁtted with a pole mount insert.

The T12POLERIG can be ﬁtted to the top or the bottom of the

cabinet allowing systems to be mirrored with the high frequency

horn either to the left or the right.

SBAR

The SBAR allows a single cabinet to be ﬂown in “landscape” mode.

5 holes give various angle options for up and down tilt. An adaptor

is included for truss mounting.

The SBAR can be ﬁtted to the top or the bottom of the cabinet

allowing stereo systems to be mirrored with the high frequency horn

either to the left or the right.

The T12GRID is used to vertically array TORUS for up to 6 cabinets.

Cabinets may be ﬂown from the T12GRID inverted allowing stereo

arrays to be mirrored with the high frequency horn either to the left

or the right.

T12HRIG

The T12HRIG is used to horizontally array TORUS for up to 6

cabinets. A single HRIG can be used to suspend up to 3 T12

cabinets and arrays consisting of 4 to 6 cabinets use 2 x T12HRIG.

T12GRID

TORUS USER GUIDE V1.0

TORUS USER GUIDE

T12TRIG

The TRIG is a transition grid between vertically arrayed TORUS

SXCF118 subwoofers.

T12GSRIG

The T12GSRIG allows for up to 3 x TORUS cabinets to be

mechanically ground - stacked to SXCF118 subwoofers for safe

deployment.

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.
