Page 6: Thv
The THV is very high performance, vertically formatted, all‐horn, three‐way systems in a single, wide‐bandwidth package. The THV is bi‐amplified. New drivers have been developed for improved performance in all bands. The Hybrid™ low frequency section comprises a horn‐loaded 15” (380mm)/4” (100mm) voice coil driver that is reflex loaded to extend the LF output to below the natural cut‐off point of the horn. The new LF driver features a water resistant cone and triple roll surround for increased excursion. The THV mid horn has a unique ‘phase‐ball’ loading device which maintains the constant directivity characteristics of the horn at the upper end of its range. It is driven by a new 10” (250mm) midrange driver with an aluminium demodulating ring for improved high‐mid clarity and reduced distortion when driven hard. The 70° x 40° THV HF section features a neodymium 1” (25mm) exit compression driver with a Kapton diaphragm for high sensitivity and extended HF performance. The internal mid/high passive crossover allows this three‐way system to be driven in a bi‐amp configuration. The THV is bi‐ amplified and must be used with a system controller. Martin Audio DX0.5, DX1.5, DX2 or iK42 may be configured to provide the recommended 2‐way crossover and limiter functions. Martin Audio DX0.5, DX1.5 or DX2 may also be used to configure THV systems with additional sub‐bass cabinets – e.g. THV + SX218 combinations. TH Series User Guide V1.0 ... -

Page 9: Safety First
TH Series USER GUIDE Safety first It is important that loudspeaker systems are used in a safe manner. Please take some time to review the following points concerning safe use of TH Series loudspeakers. Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for a long period. Never stand close to loudspeakers driven at high level. Stacking Ensure that the floor or stage is level and solid Do not stack speakers too high outdoors where winds could topple the stack ... -

Page 14: Wiring Diagrams
TH Series USER GUIDE Wiring Diagrams There are several ways that TH systems can be configured so we will now look at some practical wiring examples for the most common system configurations. System A‐ basic set‐up bi‐amping THV or THH This is the most simple system set up for stereo operation, connecting from your source, often a mixer, straight to a DX0.5 (or other system processor) using balanced XLR "microphone" cables. From the DX0.5 we take four outputs, two low frequency and two high frequency and these are routed to the two amplifiers. We then use a speaker cable that combines two Neutrik NL2 or NL4 Speakon connectors into a single 4‐core speaker cable to go from the amplifier outputs to the TH speaker inputs. This could also be achieved with a custom patch panel using NL4 panel connectors with short speaker cables routed from pins 1+/‐ and 2+/‐ on the panel to the high and low frequency amplifiers. This will allow a standard 4‐core speaker cable can be used between the panel and TH speaker. See the chapter on amplifier selection to choose the most appropriate amplifier for use with the TH cabinet. TH Series User Guide V1.0 ... -
Page 15: System B Basic Bi-Amp System Using Ikon Ik42
TH Series USER GUIDE System B basic bi‐amp system using IKON iK42 This system is similar to System A running a stereo pair of THV (or THH) bi‐amplified. This time we have used an iK42 amplifier from the IKON range. This makes system wiring extremely simple. First we can disregard the loudspeaker processor as the amplifier has on‐board DSP and factory presets are available in Vu‐Net to add the correct parameters to each channel. Secondly, the amplifier has four channels so only a single amp is required to drive a stereo pair of THV (or THH), in addition the output wiring combines amplifier channels onto single NL4 connectors so output 2 is available on both pins 1+/‐ on channel 2 NL4 and also on pins 2+/‐ on output channel 1 NL4. Likewise, output channel 4 appears on channel 4 NL4 and channel 3 NL4 on pins 2+/. This makes driving bi‐amped cabinets very simple as a standard 4‐core NL4 speaker cable can be used straight from the amplifier to the THV. No special speaker cables or patch panels are necessary. TH Series User Guide V1.0 ... -
Page 16: System C- Introducing Subs
TH Series USER GUIDE System C‐ Introducing Subs This system adds a pair of subwoofers to enhance the extreme sub frequency response of the system. On this example we have used the SX218 twin 18" direct radiating ported subwoofer. The Martin Audio DX0.5 is again used for system processing, this time using all six outputs to provide left and right outputs for sub, low and high frequencies. A DX1.5 or DX2 may also be used or even a third party processor, parameters to program these are available in spreadsheet form on the Loudspeaker Settings page on the Martin Audio website. As well as applying the recommended equalisation the processor adds a limiter in the final stage of processing to protect the system from being damaged by being over‐driven. The XLR feeds from the mixer go to the inputs of the DX0.5, the DX0.5 outputs should be connected to the amplifier inputs with short XLR cables. As with the basic system, a cable combines the outputs from the HF and LF amplifiers into a single speaker cable to connect to the THV (or THH). An additional amplifier is required, this is also fed from the processor and the outputs go directly to the SX218 with standard NL4 speaker cables. TH Series User Guide V1.0 ... -
Page 17: System D- Using An Ikon Ik42 And Sxh218
TH Series USER GUIDE System D‐ Using an IKON iK42 and SXH218 This system is similar to the previous system in that is uses a pair of THV (or THH) and a pair of subwoofers but this time using the SXH218 Hybrid® loaded 2 x 18" sub for ultimate sub frequency reproduction and uses one of the Martin Audio IKON iK42 four channel amplifiers to drive the low frequency of the THV and the SXH218s for a neat solution avoiding having to add a third amplifier. Channels 1 and 2 drive the LF of the THV and channel 3 and 4 drive the SXH218. A separate, smaller amplifier is deployed to drive the HF which doesn't require the same power level as the LF and sub. As with the previous system, there are left and right connections from the mixer to the input of the DX0.5 (or DX1.5, DX2). Output Channels 3 and 6 on the DX0.5 connect to inputs A and B on the amplifier driving the THV high frequency using a pair of short XLR cables. Four more XLR cables connect from outputs 1, 2, 4 & 5 on the DX0.5 to the inputs of the iK42. Whilst we have used the DX0.5 this wouldn't strictly be required for the LF and Sub as the iK42 has on‐board DSP. Processing would however be required for the feed to the amplifier driving the HF unless this also has on‐board DSP. Speaker wiring as before uses a custom cable to combine the LF and HF feeds onto a single 4‐core cable (or a patch panel could be used), this cable is fed to the THV. Separate standard NL4 cables go from outputs 1 and 2 to the SXH218s. ... -
Page 18: Eye Bolt Mounting
TH Series USER GUIDE Eye Bolt Mounting All TH systems have threaded inserts rated for flown installations. Both TH speaker enclosures have M10 threaded inserts. Most commonly these are used in conjunction with shouldered eye bolts for suspending the cabinets using appropriately rated chain or steel wire. Martin Audio's HTK00004 (M10) are rated for use in flown applications. Note that if you plan to use alternative eye bolts these must be shouldered cast steel or machined NOT formed steel types commonly available from DIY stores. They must have a safe working load rating compatible with the weight of the cabinets. The THV enclosure is designed for use in 'Portrait' and the THH in 'landscape' format, We recommend using a minimum of four eye bolts with which to suspend the cabinet irrespective of which orientation is used. In most applications two eye bolts are used as the primary support left and right. A third attaches to the rear of the cabinet and is used to adjust the down‐tilt of the cabinet as required. The fourth eye bolt is used to attach a secondary safety line which should be attached to a secure mounting point which is independent of the primary flying point‐ round a girder or similar.
