SPL stands for Sound Pressure Level. It is a standard measure of the atmospheric pressure of a sound wave in units called "decibels" or "dB". Conversational speech is usually in a range of 68-70 decibels. Loudspeaker manufacturers will typically provide the SPL rating for their speakers with an actual reading taken at a distance of 1 meter in laboratory or "near perfect" ambient conditions. A 600-watt PSAIR22 system produces an SPL of 138 dB @ 1 meter. This will result in speech reception at a distance of 1 mile in the 68-70 dB level.
What is the difference between the "range" or "distance" on the specifications and what I can expect in a real life broadcast from a PA system?
The SPL reading is typically extrapolated to long range distances using standard accoustic formulas. This is done because there is no perfect place where all systems could be tested under the same ideal conditions at distances over a mile. So the range is stated under the premise of "idea conditions". What you can expect for your range will vary every time you use the speakers due to the noise of engines, traffic, crowds, weapons, etc. both near the speakers and near the audience, as well as the amount of humidity, wind turbulence, obstacles in the path, the nature of the terrain, etc. Because you never know what conditions you’ll be in when you need to broadcast, you should get the most powerful system your budget will allow. You can always turn down the volume on a strong system, but a weak system will put limits on the range you can expect and in some cases will put lives at risk.
Power Sonix airborne PA can be controlled either by our hand-held remote control (PS-RCU) or by 3rd party cockpit audio panels that have a "PA" or "AUX" output capable of sending an adequate signal to the Power Sonix amplifier. For dzus mounted audio panels, we recommend Technisonics (www.til.ca). For integration with cockpit headset microphones, preferably bone conduction or other noise cancelling mics), integrating with the cockpit audio panel is required.

Power Sonix systems will stand up to the harshest environmemts in the desert and on the open sea.
Yes. Power Sonix loud speaker systems can be integrated with wireless tranceivers for wireless remote control. This is more common for vehicle-mounted systems or back pack systems. Have your systems engineers contact Power Sonix during the early planning stages so that appropriate technical issues can be identified and quotes can be provided.
All Power Sonix systems, with the exception of the AHD1200, are designed for use with 28-32 Volt sources. Specifications are based on 28V. Lower voltage, such as 24V vehicle batteries, can be used with good success, but they will nor perform to the specifications based on 28V power. If using a lower voltage power supply but needing optimal performance, ask for the "+" series from Power Sonix which includes a DC-DC converter with the amplifier to boost the power up. Refer to the Power Sonix brochures and manuals for more information regarding current draw and circuit breaker recommendations.
Yes. Power Sonix manuals include the drawings for our cables. However if a warranty issue arises and it is determined by our engineers that the user-provided cable is at fault, the warranty on other affected Power Sonix components will be voided.
Can I use someone else’s amplifier with a Power Sonix speaker array or a third party speaker array with a Power Sonix amplifier?
No. Power Sonix is a provider of loud speaker systems, not individual components. The performance of our technology is dependant upon our fully integrated system as designed. Our published specifications can not be achieved when substituting inferior third party products. The poor performance of non-Power Sonix components used in conjunction with Power Sonix components would be detrimantal to our brand and reputation. Any such usage will void your Power Sonix warranty.
Absolutely. Power Sonix engineers can work with your team to design a system for your specific needs, for aircraft, vehicles, back packs, land-based installations and ships. Click here to see examples of custom systems.
While we appreciate the natural business tendancy to "eliminate the middleman", our agents are the face and voice of Power Sonix in the markets they serve. They are tasked with getting our products marketed and included in procurement specifications. Agents provide quick in-country response to warranty issues and are the end-user’s personal, local link to Power Sonix. These tasks take time, money and loyalty. Our agents depend on us to honor their investment and loyalty once RFPs, RFQs, Tenders, etc., hit the streets and every outfitter, importer and systems integrator tries to get quotes for our spec-matching products. If you feel you are not being adequately served by our agent, please contact us with the details of your situation so we can address your issue and provide an appropriate business response.
