Medeli DD506 Digital Electronic USB Drumkit new with 1 year warranty DD506’s design is based on the DD505 but fitted with a number of revolutionary new playing options that are certain to appeal to drummers. More complete than ever… The DD506 is a full-fledged drum kit with over 307 drum and percussion voices. Choose one of the 20 preset drum kits or simply compile your own and store it in the designated memory with 30 free slots. The sound module is packed with drum kits from all over the world. Whether you pick a standard Rock or Fusion set, or maybe rather a Drum ‘n Bass or Vintage kit, the DD506 has it all. The aluminum rack is part of the standard equipment. Play like an acoustic drum kit… An acoustic drum kit offers various nuances when playing on drums and cymbals. These nuances are now also available on the pads of the DD506. The cymbal pads may be played on top as usual, or at the rim in order to distinguish between ride and crash sounds. The pads ensure an authentic playing experience; the realistic ‘feel’ enables dynamic play. The sensitivity of both pad and rim may be adjusted independently. The drum kit may be further fitted by adjusting the stereo image, volume and pitch for each pad. The touch response is adjustable per pad in six degrees. Whether you play Rock or Jazz, the pads can be fitted to every style. The sound module… The DD506 sound module has a separate input for each pad. All pads and controllers can be connected quickly and easily by means of the included multi-cable. The controls are very clear which allows you to set the sounds per pad, control the metronome, fit cross-talk between separate pads, or adjust the reverb. Apart from the 307 drum and percussion voices, a complete GM voices set is available which can be controlled on 16 MIDI channels. This makes it possible to play MIDI files from a computer with the sounds of the module, using the USB connection. Connection options… The DD506 has audio exits to connect it to the drum monitor (AP30) or an external sound installation. The module may be connected directly to a computer by means of the USB connection. All played parts can then be recorded live and played back by means of a sequencer program. This is ideal for study or studio sessions.

Yongnuo YN160 III LED Light Yongnuo YN160 III is small, lightweight, and extremely portable so taking it on-location is a breeze. There are 192 LEDs arranged across the panel. It also comes with 2 CT filters that slide into the front of the unit. Diffusion panel filter does work very nice, and it provides nice diffusion. If you're looking for even more diffuse light, you may need to use another diffusion material over the light. Luckily, it's more than powerful enough, so you'll still get plenty of light with a diffuser.LED light panels are advertised mostly for video lighting, although We've found them to be incredibly useful for indoor photography projects also. The adjustable silver barn doors come mounted to the front of the unit, and they fold flat for storage. As with most LED panels, the barn doors are only slightly effective for narrowing the light output. It's mostly designed for wide-angle lighting. YONGNUO YN160 III LED - FEATURES Yongnuo YN160 III is equipped with the SET button and relevant functions,which can save the luminance and color temperature as you need, which is convenient for your next use. YN160 III Adopts 192 high-quality LED lamp beads with chips of extra-large luminous area. In the same energy consumption, the luminous intensity is greater, the facular is more uniform and service life is longer. YN160 III adopts the encoder digital dimming system which can be separately adjusted to rough dimming and fine dimming modes, more convenient to use. On the LED digital display screen of YN160 III, the parameter of the power output is intuitional Supports external DC power input, which is convenient for your long shooting (power adapter is not included and can be purchased separately) YN160 III adopts YONGNUO proprietary LED driving technology which does great help to effectively avoid corrugation and stroboscopic flash. YN160 III is supplied with two color temperature plates so it is suitable for use under different environments.
