Dual port MADI card supports two streams of 64 channel bi-directional 24-bit 48kHz serial digital audio transmission using two 75 ohm coaxial cables per port. An additional AUX connector can be configured to mirror stream 1 outputs, pass thru stream 1 inputs, or as a word clock input or output.. Daisy chain or split signals to multiple devices, sync with either stream or an external word clock. The second port can be configured as an independent stream or as a redundant backup connection using a second cable. Signals from either stream can be routed to the iLive channels in blocks of 8. iLive and GLD outputs can be patched to MADI and appear at both stream outputs. M-MADI is one of a range of digital audio networking options available for iLive and GLD to enable integration with other systems, digital mic splitting, multi-track recording and system expansion. It can be fitted to the Port B expansion slot in iLive fixed format MixRacks (iDR-16, iDR-32, iDR-48, iDR-64) or expander (xDR-16), Port A/B in iLive modular MixRacks (iDR0, iDR10) and Port A of iLive modular surfaces if they are fitted with the new RAB-2 standard. It can also be fitted to the I/O Module expansion slot in a GLD-80 mixer.

NE555 + CD4017 LED Flash DIY Kit 3-5V Light LED Module Feature: Power supply voltage: 3-5V PCB Size: 88 x 25mm This kit is not included instruction. Principle: This kit is made up main circuit and decimal counter circuit, from the core of the self-excited NE555 multivibrator power through R2, R3, R4 charge the capacitor C1, C1 started when charging, NE555 2 feet still in low, so the output pin 3 goes high when power through R2, R3, R4 to charge C1 to 2/3 of the supply voltage, the output pin 3 level from high to low, NE555 conducting internal discharge, capacitor C1 through R4, R3, NE555 7 feet discharge until the voltage across C1 is less than 1 /3 of the supply voltage, NE555 and 3 feet level from low to high. C1 and charge again this cycle oscillations formed. Charging time: 0.695 (R2 + R3 + R4) C1, discharge time: 0.695 (R4 + R3) C1, R4 can be adjusted to control the output frequency of the oscillator, the oscillation clock signal is applied continuously NE555 CD4017 14 feet, the output terminal 10 is connected with the CD4017 10 LED, when the output terminal 10 turns CD4017 generated clock signal is applied at a high level, the D1 - D10 are sequentially lit to form a water -light effect. You can adjust the flow rate adjustment R4 LED lights. Note: This is a DIY kit, you need to assembly it. This kit is not included the instruction. Package included: 1 x NE555 + CD4017 LED Flash DIY Kit
