SINGLE RF-603 SPEEDLIGHT FLASH TRIGGER FOR CANON The RF-603 Wireless Flash Trigger act as a wireless flash trigger as well as wireless shutter release trigger. RF-603 supports all Canon DSLR Camera and support Flash Speedlight with "Sleep mode" function: Nikon Canon Olympus Pentax Samsung and other Speedlight flashes which has "Wake up" function The RF603 has been improved in several functions: Transceiver-based system: units automatically detect when to switch to either transmitter or receiver mode. Hot shoe pass-through, allowing on-camera flash and radio triggering to be used simultaneously. Improved shutter sync speed up to s Use AAA batteries (not included) Improved on/off switch Prontor/Compur (PC) port for off-hot shoe synchronisation Non-proprietary 2.5mm (sub-miniphone) port for shutter release cables Shutter release cable included (Select between C1- and C3 cable) Since it is now a transceiver system you can now use it more flexible. With e.g. 4 RF-603 you can trigger 3 flashes (1 trigger, 3 receivers) as well as trigger the camera itself and then trigger 1 flash. One more good thing is that the only power source you now need is 2 AAA batteries. The power switch has been improved an now should prevent from accidently firing in the camera bag which could consume a lot of the battery power.

PN-2 is one of the Soundright "Silver Angle" series cables. Adopt double red and black 0.12mm*36 multi-strand OFC wires covered by PE intertwisted together as the core wire. The red acts as live line, and the black acts as Neutral line. Otherwise, the ground wire is made up of a φ1mm single silver-gilt wire and the whole aluminium foils covered the core wire. Because of the character on electromagnetism shield of aluminium foil, the anti-jamming capability for PN-2 is better than the other power cord with ordinary structure design. PN-2 could make the sound from devices purer and more powerful, and rich on the high-medium. Adopting this power cord for video devices, can also make the images stable and vivid. To be more safe and reliable, this power cord also matches with the high-quality attaching plug.http://zandphighendaudio.yolasite.com

Yamaha MSP7 Active Studio Monitor (SINGLE) POWERED FOR UNCOMPROMISED QUALITY The trend towards choosing powered speakers for production monitoring is based on some very sound logic. By integrating and matching the power amplifiers and speakers, the relationship between them can be kept under perfect control for superior performance in the widest possible range of systems. Naturally the power amplifiers themselves are of the finest quality and, unlike component power amplifiers that must be designed for acceptable matching with the widest possible range of speakers, are designed and manufactured specifically to drive the system's woofer and tweeter in their specific enclosure. No matter where the MSP7 STUDIO monitors are used, and with what sources or other audio gear, you know that you're always receiving the benefits of a perfectly matched power amplifier and speaker system. You'll hear the difference. You'll also benefit from the convenience of not having to deal with external amplifiers and cabling. ADVANCED BI-AMP DESIGN There are a number of advantages to multi-amp speaker setups, but the added cost and extra equipment required can make them impractical in many situations. With the MSP7 STUDIO everything you need is built-in - all you have to do is supply the line-level input. The 6.5 inch cone woofer is driven by an 80-watt power amplifier, while the 1 inch dome tweeter has its own 50-watt power amplifier. In the MSP7 STUDIO this particular power and driver combination results in the perfect balance between the low-mid and high frequency ranges. The frequency ranges are divided via a carefully designed electronic crossover before the power amplifier inputs, featuring steep 30-dB/octave roll-off curves in both the low- and high-pass filters. The steep roll-off minimizes inter-modulation between the frequency bands at the crossover point, achieving significantly smoother, cleaner crossover performance in the critical midrange. And the fact that the crossover is a linelevel electronic design completely eliminates the loss, distortion, and sometimes severe inter-modulation that are almost unavoidable in conventional passive crossover networks driven by a single power amplifier. DETAILS THAT DEFINE SUPERIOR PERFORMANCE The MSP7 STUDIO woofer and tweeter units feature some important design innovations that contribute directly to improved sound quality. The 6.5 inch woofer, for example, features a specially treated polypropylene cone with lowdamping rubber surrounds for exceptionally smooth response. Low-reflection highrigidity die-cast magnesium baskets both maximize mechanical precision while minimizing unwanted coloration of the speaker's output. The 1 inch tweeters feature titanium domes that offer the perfect combination of light weight and rigidity for precise reproduction right up to 40 kHz. The tweeters have a powerful magnetic circuit that results in extremely fast response for crisp, natural transients, and are integrated with a waveguide that achieves uniform high frequency dispersion of 120 degrees. But precision manufacturing makes a huge contribution to performance as well as basic materials and design. The slightest eccentricity in the alignment of the tweeter domes and waveguides, for example, can seriously affect performance. So can the alignment of the coils and magnetic circuits. These are details that require a considerable investment of energy and resources to do properly, and they are exactly the details that make the MSP7 STUDIO the superior studio monitor that it is.
