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
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
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.
