Motorola TLKR T92 H2O Twin Pack IP67 Waterproof Count on the T92 H2O two-way waterproof radio to keep you connected whether on land or at sea. With its IP67 rating, the T92 H2O withstands constant submersion of up to 1m for 30 minutes and repels the heaviest rain. Floats1 Face Up With Water-activated Flashlight for Easy Retrieval Through meticulous engineering, the radio floats and is visible on the water surface. And with the water-activated flashlight, it’s even easier to find. Be Prepared for an Emergency This radio includes an emergency alert feature, allowing you to enjoy your escape to the great outdoors with confidence that others can be informed of any dangers that may come your way. When the alert button is activated, the radio transmits an alert siren followed by transmission of spoken or incidental sounds. This allows you to send the signal to other radios and warn of impending danger. You can also use the whistle belt clip to let others know that you need help. In addition, there's a built-in LED flashlight for peace-of-mind during evening adventures, unexpected emergencies and power outages. Advanced Built-in Flashlight with White and Red LEDs Select the white LED setting on the built-in flashlight to light your way during evening activities, unexpected emergencies or power outages. If your adventure takes place when it’s dark, for example, if you're stargazing or hunting at night, and you need to view maps, charts or other papers, switch to the red LED setting. This will allow you to read what you need while preserving your night vision. Power through Your Adventures There are two ways to power your radio: use the included NiMH rechargeable batteries for up to 16 hours or use three AA batteries for up to 23 hours. The T92 H2O is supplied with a dual car charger allowing you to recharge two radios at once whilst on the move in your car or van. And the charger USB cables are detachable, so you can recharge by connecting to your computer USB port. 8 Channels Each with 121 Privacy Codes With 8 channels and 121 privacy codes, totalling almost 1000 combinations, it's easy to find an available channel. Be Hands-free With iVOX/VOX acting like a speakerphone and allowing hands-free communication, you can keep on moving without stopping to answer a call. Customise Call Tones Choose what your callers hear before you start speaking by selecting one of the 20 call tones. Be Discreet Use the vibrate alert feature where audible ring tones would be intrusive. Quickly Find a Channel Use the scanning feature to see which channels are currently in use. Low Battery Alert Low battery alert reminds you when batteries are running low. Compatible with Any PMR446 Radio T92 H2O is PMR446-compliant, so you can communicate with other TLKR radios or even with radios from other suppliers by being on the same channel and privacy code. Keypad Lock The keypad lock prevents your personalised settings from being inadvertently changed. Optional Extended Batteries Enjoy hours of uninterrupted outdoor activities by selecting a high capacity battery. (High capacity battery sold separately.) T92 H2O Packaging Includes: • 2 radios • 2 whistle belt clips • 2 NiMH rechargeable batteries • 1 car charger with 2 detachable USB cables • 1 carry case • 1 user guide 1 This radio meets IP67 standards. It will withstand submersion of up to 1m for 30 minutes. Radio floats with included NiMH battery. It may not float with some AA batteries. Use of headset should be in dry environments only. 2 The communication range quoted is calculated based on an unobstructed line of sight test under optimum conditions. Actual range will vary depending on terrain and conditions, and is often less than the maximum possible. Your actual range will be limited by several factors including, but not limited to: terrain, weather conditions, electromagnetic interference and obstructions. 3 The Emergency Alert feature should only be used in the event of an actual emergency. Motorola Solutions is not responsible if there is no response to the emergency alert from the receiving group.

E Munro Egg Speaker - A Revolutionary Active Studio Monitor The sE Munro Egg incorporates a fundamental rethink of the loudspeaker engineering process. The traditional wooden box has been replaced by a scientifically proven, curved enclosure that virtually eliminates diffraction and resonant effects that distort and smear the original sound. The result is a stunning clarity that brings the smallest details into focus and yet delivers the entire mix as a coherent whole. In this video, Andy Munro talks about the the Egg system design, the manufacturing process, his partnership with sE Electronics and the 'Egg' concept: VIDEO: sE Munro Egg - A Revolution In Monitor Design sE Munro Egg 150 Monitoring System The system is complete, with a free standing control unit that delivers a perfect bi-amplified power match to the egg drive units, source select inputs, active analogue crossovers, LF and HF trim pot equalisation for room and location set-up compensation and a mid-band control to emulate the mid-range response of both Hi-Fi and NS10 type speakers. Above all, the sE Munro Egg 150 Monitoring System is designed to deliver the highest quality sound with the absolute minimum of coloration. In one word - Truth. Key Features of the sE Munro Egg 150 Monitoring System Unique monocoque shell construction (rigid and resonant neutral) Near zero diffraction interference (smooth frequency response) No internal standing waves (greatly reduced smearing) Perfect bass port integration (superb transient response) Free standing control unit and integrated amplification with 3m matched speaker cables Dual input switching and level control Ultra fast and low distortion (4*50W) with 100W/Channel headroom indicator Precise 'sweet spot'

Monkey Banana Turbo 6 Active Studio Monitor (Pair) The Turbo Series is not only stylish in appearance, but also employs serious engineering to achieve the best acoustic performance. The Bass-reflex acoustic design combines maximum efficiency and optimal bass extension. The MDF material ensures proper damping of vibrations from the drivers. All this is done behind a sophisticated industrial design utilising modern fashion elements. In order to achieve this perfect combination of sound quality and appearance, the Turbo series enclosures were designed as a non-regular hexagon. After careful calculation and experiment, we found that the non-regular hexagonal structure is most effective in minimising standing waves inside the enclosure. We chose high quality MDF for the enclosure to not only damp out unwanted resonances, but to ensure a solid and inert structure to mount our drivers to. All internal surfaces are lined with blended wool to further damp the structure of the cabinet. Using high quality pure silk from Europe for the tweeters, the patented dome shape perfectly articulates the high frequencies out past 20 kHz. It is designed to have a low resonance (for a low crossover point) but also high power handling. Using patented technology from the Aviation industry, the PP carbon fiber / ceramic composite cone for the woofer provides a perfect balance between strength and weight. This lightweight yet strong cone ensures an extremely fast transient response from bass notes all the way through to the midrange. The custom-made amplifier design uses only professional grade multi layer PC boards (compared with the single sided PC boards used in other speakers). This ensures that the circuitry and components have better reliability and better performance, which in the end means higher fidelity sound.
