Audio Audio selectors, switches & controls Three way input selector Simple rotary switch routes any of the three pairs of phono inputs to the phono output. Metal case with gold plated sockets. [BT31] £12.99 Volume Remote Control Ever wished your amplifier had remote control for the volume? Now you can easily add IR remote control to most amplifiers with this simple device. It has two phono sockets for line in and two for line out. Simply connect it in line, position the IR receiver wherever you find convenient and Selectors, Switchers, Controls & Convertors 4 Way audio control A multi-purpose phono interconnect switcher which can be used as an Input expander or comparator. Connect up to four stereo devices (RCA phono) and use a simple push button process for signal routing. Eg pressing 1 & 4 connects input 1 to input 4. pressing 1,2 & 4 connects all three. An internal impedance matching circuit minimises audio losses. Very handy. [BT931] £19.99 4 channel stereo audio source selector Allows 4 audio inputs to be fed into one. Ideal if you wish to feed your VCR, DVD, camcorder, satellite system, TV etc into your hi-fi system which only has one Aux/Line input. Features phono inputs for simple connection and non slip suction feet. [SOURCESEL] £14.99 Digital audio – what’s what? In the earlier days of digital audio the conversion from digital back into analogue was always performed within the CD player itself. Now, particularly with the advent of DVD, the thinking is to preserve the signal in its digital form as long as possible to keep signal loss and distortion to a minimum. This is achieved by routing the signal directly from the player in its digital form into a suitably equipped amplifier or TV for decoding and amplification. This process has led to a bewildering array of terminology, a few of which we’ve attempted to explain here: S/PDIF, an abbreviation of ‘Sony/Philips Digital InterFace’, is a defined standard for PCM stereo digital audio. It uses a single phono (RCA) connector for electrical signals or a TOSLINK connector for optical signals (the information contained in the signal is the same in either case, and convertors are available to change one type into the other). S/PDIF signals use different sampling frequencies for different applications and can carry stereo audio (CD, minidisc or DAT) as well as multi-channel surround sound. AC3 (Adaptive Coding 3) is an audio compression standard based on the S/PDIF PCM audio delivery system. Dolby Digital Surround AC3 is a 6-channel surround sound system that uses the AC3 compression. The sound is encoded to 5.1 channels (five full bandwidth signals plus a low frequency channel for the subwoofer), and then encoded using the AC3 compression standard. AC3 systems are backwards compatible with S/PDIF in that they will also decode stereo, but S/PDIF systems will not necessarily decode AC3. DTS, an abbreviation for ‘Digital Theatre Systems’, is another multichannel digital audio standard which uses less compression than Dolby Digital to give an arguably better sound. Some players and amplifiers support both AC3 and DTS decoding although at time of writing there is not much DTS encoded material available. THX is not an audio standard in its own right, rather it is a very tight set of specifications to which THX-certified equipment must be manufactured. The brainchild of George ‘Star Wars’ Lucas, it was intended to prevent the soundtrack of his films sounding different from cinema to cinema because of equipment variations. In theory at least, the film soundtrack should be faithfully reproduced in any THX-certified cinema. THX in the home is generally an exercise in open-wallet surgery as certified hardware is phenomenally expensive. have easy volume adjustment. Leds for power and confirmation of ‘up’ and ‘down’ commands. It can be used in a number of ways: • Inline in between pre/power amp combinations • Within tape line out/line in loop (if vacant) with the amp set to ‘tape monitor’ • In between say CD player line out and amp line in (to control that device volume only). [VRC] £59.99 Sound mixing Video sound mixing is the process of adding to or replacing the soundtrack on your footage at the time that it is edited. Connections are made as shown in the diagram. The norm is to have three channels on the audio mixer; one channel being the incoming camcorder soundtrack, another being a microphone input for commentary, and the other for music from a tape deck, CD etc. The important thing about a mixer is that all three channels can be present simultaneously, and so the final result is not necessarily just one channel or another. If you want to add ‘live’ commentary whilst editing, it can be frustrating if you make a mistake as the whole thing needs to be rerecorded. It is easier to record the commentary onto an audio cassette and then mix it in on the final copy. AUDIO Video recorder VIDEO Camera in MUSIC Cassette player Amplifier CD player Music in Master out Sound mixer Digital audio / convertors Video recorder AUDIO TV Microphone Headphones Digital audio delay Plasma/LCD & Projector owners - do you get frustrated by the lip-synch errors when viewing? It occurs because of a delay introduced by the processing of the picture. The audio doesn’t go through the same processing hence the audio appears ahead of the image. If you use an AV amplifier for your sound then we have a solution - the Felston DD740 digital audio delay module. It allows easy adjustable audio delay allowing you to get everything back in perfect sync. There are two inputs and you can switch and adjust from your armchair with the supplied remote. • Dual digital audio inputs and outputs (optical and coax) • Remote control • 680ms maximum delay (340ms for 96kHz signals) • Automatic input switching, with input's last delay restored • Can convert optical-to-coax/coax-to-optical, for connecting 2 sources to an amplifier with a single input • 12 user-programmable presets (6 per input) • Adjustable display brightness • Discrete IR commands for integration with learning remotes • No effect on audio quality thanks to bit-perfect reproduction [DD740] £129.00 Digital audio convertor A universal digital audio convertor that will change digital optical signals (Toslink) to coaxial and vice-versa. Supplied in a screened case with UK power supply. [BT992] £19.99 38 all prices include VAT Order by Tel: 01332 830550 or Fax: 01332 830551
