Universal Remote Control

Universal Remote Control MX-500

Universal Remote Control MX-500

Home Theater Master MX-500 10-Device LCD Viewscreen Remote Control Flawless Like-New Condition. Cash Only. Pickup in San Francisco Marina Only.

The URC Home Theater Master MX-500 Universal Remote Control Is A Truly Unbelievable Value! Includes Instruction Manual.

This preprogrammed and learning remote control is designed to simplify your entertainment experience. The brightly backlit LCD viewscreen actually has 26 individual pages for operating up to 10 audio and/or video components. The component buttons are strategically placed around the LCD viewscreen and can be renamed, according to the actual components that your audio or video system may include.

Basic set-up of the remote can be fast and easy.

The MX-500 boasts a built-in preprogrammed database of over 1,000 audio and video component codes, and is also fully capable of learning your home theater system's audio/video components remote control codes (up to 530 functions). For those households that require more than one remote control, the MX-500 can easily be cloned via infrared from another programmed MX-500. It's that simple!

Ease-of-use

The MX-500 is ergonomically designed and weight balanced to fit comfortably in one hand. The brightly backlit LCD viewscreen and buttons make navigation within a darkened home theater environment a breeze. To further enhance the navigation of the remote control, we have incorporated a multi-directional joystick.

Additional creature comforts

The MX-500 Punch Through feature enables control of one component while the remote is actually in another component mode. For example, you can adjust the volume of the amplifier while actually in the DVD mode, eliminating the need to toggle back-and-forth from the DVD screen to the amplifier screen.

The macro feature allows the remote control to be programmed to send out multiple commands at once. The unit has 3 dedicated macro buttons, a "Power" button and a "System Off" button that send out up to 20 commands each. 10 device buttons send out up to 15 commands each, and 50 favorite channel buttons send out up to 10 commands each. For example, the MX-500 can be programmed to turn on all the components within the home theater system at just the touch of a button!

The MX-500 also incorporates a memory back-up system designed to prevent memory loss for up to one year, should the batteries be removed. Features and Benefits

yamaha tyros 3

yamaha tyros 3

The new Yamaha Tyros 3 Arranger Workstation is designed to provide you with all the sounds, styles, and features you need to perform your music. The Tyros3 utilizes the latest technological advances from Yamaha like Super Articulation 2, studio quality reverb, performance enhancing control sliders and TFT VGA screen.

Since the original Tyros was launched in 2002 Yamaha has been at the forefront of the high end keyboard market. The launch of this new musical keyboard is guaranteed to maintain its position as the market leader and most exciting keyboard instrument available.

The most unchanged aspect of the instrument is its overall appearance. Yamaha wanted to maintain the family look, but, more importantly, maintain the operating system so owners of both the original Tyros and Tyros2 would instantly feel at home with this new electronic keyboard. However, there are a number of important changes to the panel, the most obvious of which is the addition of 9 sliders positioned beneath the LCD screen. These sliders effect a number of different functions, depending on the feature selected, but for lovers of organ sounds, their most important function is to change the organ footages, in a similar way to traditional ‘drawbar’ based instruments. This makes changing voices ‘on the fly’ very easy.

The Tyros 3 is a musical instrument – so sound quality is all important, and Tyros3 takes the listeners sonic experience to new heights. One of the key contributors to this is the brand new Super Articulation2 voices. Super Articulation was first introduced on the Tyros2, adding many detailed musical nuances to the orchestral sounds. This has been taken to new heights with Super Articulation2.

Each Super Articulation2 sound features a vast selection of supporting samples to the main ‘voice’ sample. Depending on how you play (or if you use the new Art1 and Art2 buttons) the keyboard automatically selects one of these ‘supporting’ samples to add incredible level of realism. Any of the Super Articualtion2 voices can glissando, bend and articulate, just like the real thing. However each voice responds differently, like the individual instrument. Frankly you need to hear it to believe it! This is only the beginning. There is a host of new sounds across every voice section of the instrument. This includes a brand new Piano voice (taken directly from a Clavinova CVP range) and a complete new organ section, with new Theatre and Jazz organ voicing and a range of new effects.

The accompaniment section has been greatly extended, offer a total of 450 styles. Any styles that have been carried over from Tyros2 have been upgraded, and many have new Intros and Endings, creating a total new musical feel.

Tyros 3 comes complete with 80GB hard drive, allowing a massive amount of storage space for registrations, additional styles/voices or recordings. The LCD screen uses TFT technology, making it vibrant and clear, and can be seen clearly from just about any angle. A new ‘sync start’ function ensures perfect timing when engaging a multipad, while the built in LAN port allows easy connection for those using the unique Yamaha Internet Direct Connection feature.

Newly Added features Compared to Tyros 2

11 SA2 (Super Articulation 2) Voices created with AEM (Articulation Element Modeling) technology

Enhanced Piano, Guitar, Drum Voices, etc. and Synth Voices inherited from flagship MOTIF synthesizer

2 track hard disk audio recording, hard drive included and studio quality reverb

mk484 radio

mk484 radio
rf circuit

A simple MK 484 IC tuned rf (trf) radio

In 1970 Ferranti started the development of a single-chip AM tuner, and by 1973 it became widely available for use. The 414 is no longer in production, but a follow on IC, the MK484 recently became available, and incorporates essentially the same features. It is a 3 terminal device which packs ten transistors providing 3 stages of rf amplification with an input impedance of about 4 Megohms, and giving 72 dB of gain with about 30 millivolts of audio output (rms). Thanks to the editors of Practical Wireless a ham magazine in the UK, and Dr. Philip Miller Tate of Kingston University, who has probably built a dozen or so of these in one guise or another, and sent me one fully assembled, here is one adaptation of this versatile little chip which gives you a nice little portable radio which is stable and virtually idiot proof to build, needs only a 1.5 v battery, and requires a tiny thimble full of parts to give you near-superhet performance. Here is the schematic of the circuit that PW came up with:
