This add-on board is designed to provide a pair of balanced audio outputs for the High-Quality Stereo DAC (Digital to Analog Converter). Two 3-pin male XLR connectors are used for the new outputs and they can either replace or augment the existing unbalanced outputs without affecting their performance. Balanced audio is used in recording studios and on stage because of its improved noise immunity. Picture of the project:      This is due to the fact that the signal is sent differentially (ie, as two signals 180° out of phase) and then converted to a single-ended voltage signal at the far end. If any noise is picked up in the cable, it affects the two out-of-phase signals equally so that when the signals are subsequently subtracted, most of the noise is eliminated. Parts layout: In addition, the DAC’s performance at the balanced outputs generally exceeds that of the unbalanced outputs, although only by a small margin. The signal-to-noise ratio, frequency response and chann...

Look at any good car stereo system and you’ll probably see a Pioneer car stereo unit plugged into the console. Alongside with quality speakers and a strong lineup of accessories like LCD panels and navigational devices, Pioneer products/Pioneer car stereos have earned a huge following the world over.   The Pioneer Company is a Tokyo-based corporation, and is one of the world leaders in digital entertainment products. The Pioneer Company was first founded in 1938 in Tokyo as a small radio and speaker repair shop business but today, they are recognized as a leader in technology advancements in the consumer electronics industry. The company is truly deserving of their name. They are respected for many innovations such as interactive cable TV, the Laser Disc player, developing the first Compact Disc player for the car and the first detachable face car stereo, DVD and DVD recording, plasma display, and organic electroluminescent display. Their strength in optical disc and display techn...

You know sometimes just being willing to try to fix stuff allows you the freedom to buy things that you otherwise would’ve steered clear of, even though they’re not really broken. I was in one of the local guitar shops not long ago; one that sells second-hand pedals. In their pile they had this: It’s an MXR Phase 90 with the back cover missing (and replaced with some electrician’s tape): I asked how much they wanted for it and they told me that it was broken. I said I was still interested, figuring it might be worth my while to try and repair it if the price was right. After some discussion with the pedal owner (one of the guys who works in the shop), they asked me for NT$300 (about US$10), reminding me again that it was broken. I figured for ten bucks it would be worth it for parts alone, so I readily handed over the cash. The guys in the shop were amazed that I was willing to buy a broken pedal. Meanwhile I was amazed that that seemed so strange to them. So I got it home and peeled ...

ELF is the nanocopter that fits in your pocket and shoots high definition (HD) aerial photography. And anyone can use. Our smartphone app (iOS & Android) connects to ELF via Bluetooth 4.0 in seconds, allowing you to take off the moment you hit the throttle. [ ]

Basket (frame) Made of a metal plate that will support all parts of the speaker where the speaker of the other speakers can be attached to the intact  Magnet Here is used to generate a magnetic field of permanent magnets to be used to drive the voice coil, so as to produce sound. Parts of speaker Voice Coil Voice Coil is an important part of a speaker. Voice coil consists of Robbin (where rolled coil) and coil (the coil BWR - Brass Wire Rope), Coil is going to move in accordance with the signal diterirna. Spieder or Damper Spider or suspension dampers are used to speakers that serve to dampen the vibrations of the voice coil, so the voice coil can move freely. Cone Paper Paper Cone is part of the suspension of the speaker who serves simultaneously as an amplifier of vibration caused by the voice coil so it can form a clear voice signal received from the speakers. Dust Cap Dust Cap serves to channel sound vibration with paper cone and protect the inside of the speaker (where the air...
