USER MANUAL SPJ Passive Speaker 178.003 Skytec

OUTPUT (to second speaker)3 - 20

Congratulations on the purchase of this SkyTec passive speaker box. Please read this manual carefully prior to using the unit. TO ENSURE MANY YEARS OF TROUBLEFREE USE, PLEASE OBSERVE THE FOLLOWING

• Hearing damage: SkyTec loudspeakers are easily generating high sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew and audience members. Care should be taken to avoid prolonged exposure to SPL in excess of 85 dB.

• Make sure that the amplifier is switched off when the speaker box is connected or disconnected.

• The box must be installed by a qualified technician who has knowledge of the techniques.

• Do not overload the box to avoid damage to the speakers.

• Connect the box only to a good quality amplifier: Direct voltage at the amplifier output will damage the speakers “Clipping” (overdrive) of the amplifier can damage the woofer, tweeter and horn speaker

• Do not overload the speakers to avoid damage to the components.

• Do not place an open fire (candle, etc.) on top or next to the box - FIRE HAZARD

• For indoor use only. If the box is used outdoors, you need to make sure that no humidity can enter the box.

• Make sure that the box is placed on a stable, solid surface.

• The boxes can be stacked but do not put more than 60kg weight on the box.

• The boxes can be hung. Use only strong and approved mounting material. The installation should only be carried out by a qualified technician who has knowledge of the techniques and regulations regarding the mounting/hanging of speaker boxes. During the mounting, make sure that nobody is standing below the mounting area.

• Use only stands which are designed to support the weight of the speaker. Do not attempt to place more than one speaker on a stand designed for a single speaker.

• Do not place liquids on the box and protect it against humidity. Humidity can shorten the life time considerably.

• Only use suitable means of transportation if you want to move the box – BEWARE OF YOUR BACK!!

• If the unit is damaged to an extent that internal parts are visible, DO NOT connect the unit and DO NOT switch it on. Contact your dealer or Tronios.

• Never try to repair the unit yourself. It does not contain any user serviceable parts. All repairs must be carried out by a qualified technician.

• Set the amplifier to the lowest volume prior to switching it on.

• Keep the unit out of the reach of children.

Protect your environment. Recycle packing material whenever possible. Do not throw a faulty unit into normal household waste but bring it to a special collection point. A large part of it can be recycled.

General - 35mm titanium-diaphragm compression driver; - Molded one-piece baffle with integral 90°x60° constant directivity horn; - Multi-angle enclosure for flexibility in usage; - Professional & study ABS enclosure; - Enclosure and baffle are molded of tough and durable co-polymer material. This range of speakers is able to withstand high powered impacts; - A heavy-duty, perforated metal grill protects the woofer; - Ergonomically designed balanced handle and lightweight enclosure for easy and comfortable carrying; - Attachment points for wall or ceiling mount brackets; - Integral 35mm pole mount receptacle with securing thumb screw. About the enclosure The enclosure and baffle of this range of speakers are made of polypropylene co-polymer. The use of co- polymer allows features such as stand mounting sockets, handholds, ports and high frequency horns to be molded directly into the cabinet. Not only do you get contemporary appearance, you also get lots of functionality.4 - 20 CABLE CONNECTIONS This range of speakers features 4-p loudspeaker connectors. These connectors are hooked in a parallel “loop-through” configuration for connection to additional speakers. For optimum performance it’s important to use cables specifically designed for speaker use. Do not use shielded “guitar” signal cables for connection to these speakers. Selection of the appropriate wire gauge is important for system operation. A cable that is too light will result in amplifier power being wasted due to the series resistance of the cable. In addition, loss of low-frequency performance may be experienced due to a degraded damping factor. The chart below illustrates the appropriate minimum wire gauge for various cable lengths and speaker impedance combinations. When using this chart, keep in mind that two 8 Ohm parallel linked speakers will equal a 4 Ohm load (see “looping speakers”).

Looping speakers Running too many speakers from a single amplifier channel may result in damage to the amplifier and/or in degraded audio performance. To calculate the combined impedance of multiple identical speakers in parallel, please use the formula below: Impedance of a single speaker --------------------------------------------------------- = Amplifier load Number of speakers connected in parallel Refer to your power amplifiers owners manual, for information on minimum recommended load impedance. INPUT PANEL Loop through capability (12” & 15” version only) The two jacks on the rear panel of this series of speakers are wired parallel. This means whatever you plug in to either of the two jacks is available to “patch out” from the other jack to another loudspeaker.5 - 20 TROUBLESHOOTING One certain method of determining if a speaker is faulty is to substitute a speaker that is known to work correctly for the suspected problem speaker. If the “normally correct speaker” is experiencing the same difficulties or problems as the suspected problem speaker, use the information below to isolate the problem. No output Possible cause Action Speaker cables Reseat all connectors Substitute known good speaker cables Check solder joins Tighten set-screws on the banana connectors or 4-p connectors Inspect cable for damage Inspect wire or connector for stray strand that may short Amplifier Make sure the amplifier channel is being fed a signal. Most amps have a “signal input” LED to indicate the presence of a signal. Re-patch the speaker to an amplifier channel that is known to work. Intermittent Possible cause Action Poor connections While it is possible for a faulty speaker to exhibit intermittent output, it’s more likely that an output cable/connector is the problem. Check the soldering on your connectors. Tighten the set-screws on the banana connectors or 4-p connectors. Constant noise, buzzing and/or humming Possible cause Action Faulty electronic Any constant noise originates in the amplifier, mixer, signal processing, source device in the signal devices, or line-level wiring. Check and correct system grounding as required. chain check for noisy sources or electronic components. Check wiring for shielding. Poor low-frequency output Possible cause Action Improper polarity When two speakers in close proximity to each other are connected out-of-polarity, they can partially cancel each other out, especially at low frequencies. Check your speaker cables to be sure they are all identically wired and connected. Check the balanced line signal cables to be sure they are all correctly wired.

Do not attempt to make any repairs yourself. This would invalid your warranty. Do not make any changes to the unit. This would also invalid your warranty. The warranty is not applicable in case of accidents or damages caused by inappropriate use or disrespect of the warnings contained in this manual. Tronios cannot be held responsible for personal injuries caused by a disrespect of the safety recommendations and warnings. This is also applicable to all damages in whatever form.6 - 20
