BeoCord 1000

Beocord 1000 was introduced in 1966 – and the Beocord 1100 that replaced it in 1967 – were the budget models of the range. They were stereo machines but had only mono monitoring.
Beocord 1500 and Beocord 1800 eventually superceded these two models; Beocord 1800 featured a mixer as in more expensive machines and also incorporated both sound-on-sound and overdubbing capabilities. Beocord 2000 was the best-selling and the best-loved machine that the company produced; this was manufactured from 1965 to 1968 and was drowning in features many not seen on anything but professional machines until the late 1970’s.
In 1969 the company introduced Beocord 1200, Beocord 1600 and Beocord 2400.

It had all the facilities you needed for recording compact cassettes and replaying them through an existing amplifier system. The combined record/playback head was made of Super Permalloy, an extremely durable material which ensured a long useful lifetime and had excellent magnetic properties. Other refinements included an electronic auto stop at end-of-tape and a switch for selecting between chromium dioxide and normal (ferric oxide) tapes.
The setting of correct recording levels was by way of individual controls used in conjunction with VU meters for left and right channels. Beocord 1101 was technically identical to Beocord 1100 but had a different exterior finish.

A Red Line speaker was so flexible that it could be placed anywhere. On the ceiling, the wall, or on the floor. You could hang them semi-permanently on the wall, and if you had a party you could place them on the floor and thereby add extra emphasis to the bass. The different ways of placing them accentuated different frequencies.
You could also tilt them if you chose to hang them on the wall. This allowed you to adjust the sound image and direct the sound right at your listening position. However, Red Line was more than merely flexible. It was an impressive bass reflex speaker with a revolutionary new cabinet that ‘curved’ round the sound thereby eliminating irritating resonance because there were no parallel surfaces.
Red Line loudspeakers followed your music tastes right up the wall if you wanted! All models except the RL35 could be hung on the wall or be suspended from the ceiling; and, if your dancing feet wanted to make the most of the bass notes, then Red Line could be positioned on the floor, supported by the built-in floor stand. By using Red Line speakers, you weren’t plagued by cables that wrapped themselves around your feet like spaghetti either; Red Line’s flexible spiral cables provided the decorative and practical answer.
The shell was cast in a hard synthetic material and the shape that was devised for the range was characterised by the fact that it allowed for practically no resonance whatsoever.
You could choose Red Line in four sizes. They started with the baby 35 watt RL35 – perfect for a Beolink round-the-house system where you needed speakers all over the place. Then there was the 45.2, the 60.2 and the immensely powerful 140’s – big and beautiful with it. All the Red Line collection came in metallic grey with a distinctive red line around the edge. A matching cord was available to accentuate the red line after which the speakers were named.
In 1991 the former Redline series – RL35, 45, 45.2, 60, 60.2, 100 and 140 were superseded by the Mark 2 range of loudspeakers: RL1000, 2000, 6000 and 7000.

With Bang & Olufsen earphones and the new BeoSound 2, it’s easier than ever to bring music with you. BeoSound 2 is our version of a light and pocket-friendly digital music player that allows you to enjoy hours of your favourite music when you’re on the move – without compromising on quality” B&O Catalogue 2001 – 2002
With BeoSound 2 you can download up to four 5 compact discs’ worth of music (depending on bitrate) and listen to it wherever you are, thus freeing up the hard drive of your home computer. It has a form and size that sits easily in the hand and in the pocket – and with no internal moving parts you never have to worry about knocks and vibrations ruining the musical experience.
The unit is made to be moved and built to last. Manufactured in hard-wearing stainless steel and firm rubber, it has been designed to withstand all the knocks that portability can throw its way. The keypad can be locked when on the move and with no internal moving parts, jogs and bumps will never interrupt the playing of the recorded music.
BeoSound 2 has been designed for transferring Internet-downloaded MP3s or music tracks that you have created yourself, into its solid-state memory for later playback through the supplied pair of A8 Earphones. Its built-in battery gives the user between 2 and 4 hours’ worth of uninterrupted use; the batteries should last for around 8 hours before they need recharging by placing BeoSound 2 into its specially-designed docking station. This special station provides the connection to a computer and acts as a convenient power charger for the player. Its 128 MB SmartMedia memory card (which may be expandable to 256MB) allows you to download up to 4 albums’ worth of music; the card itself may be reused as many times as you like. BeoSound 2 also plays back AAC and WMA-compatible files.
With simple and straightforward Bang & Olufsen operation, you can step easily from track to track and between different play lists. However, there is no display on the unit. Bang & Olufsen has made BeoSound 2 so simple to operate that you don’t need to look at it while in use. The intuitive layout of the keypad ensures that everything can be carried out with a thumb.
You can adjust the volume, step up or down through tracks or switch between different play lists – without ever having to take BeoSound 2 out of your pocket. And to make operation even easier, its one-touch control has been combined with a series of sounds that guide the user through each operation. In the same way, a light indicator on the docking station gives you the current status on the different functions including battery recharging.
If you upgrade the firmware on your BeoSound 2 and it locks itself ‘out’, then reset your apparatus by pressing “Vol Up” & “Vol Down” together and at the same time pressing “GO” for 2 seconds.
BeoSound 2 is created to be used together with BeoPlayer and Beolink® PC2, but will also function with Windows Media Player. However there is no point having a product that will last for years if its software is outdated in a matter of months. That’s why Bang & Olufsen has ensured that future software updates may be downloaded via the official BeoPlayer Web site. In March 2006 BeoSound 2 had an updated software version: 2.5, which allows for easier downloading to its SD card and also allows the use of a 2 GB card.
As from late 2002 BeoSound 2 may also be used by Mac users.
Music on the move from Bang & Olufsen – Portable BeoSound 2 always on hand
Bang & Olufsen takes another step into the digital music world with the introduction of BeoSound 2, a pocket-friendly digital music player. As with the successful Beolink® PC 2 concept, BeoSound 2 draws upon the computer as a source for musical entertainment and allows you to enjoy your MP3 files in a myriad of environments.
Fitting comfortably into the palm of your hand, you navigate simply between tracks or adjust the volume in your accompanying Bang & Olufsen earphones without ever needing to glance down. Utilising a minimum of buttons, BeoSound 2 provides you with both audible and tangible feedback during operation.
The smooth stainless steel cabinet and absence of sharp edges allow BeoSound 2 to slip comfortably into your pocket – and prevent it from disturbing you when you’re on the move.
“Digital music has proven itself to be an important player in today’s world of musical entertainment. BeoSound 2 harnesses the strengths of these file formats and combines them with Bang & Olufsen skills within ease of use, craftsmanship, design and sound quality. Whilst physically small, the BeoSound 2 experience is large – where integration with additional Bang & Olufsen products plays an considerable role”, says Bang & Olufsen President & CEO Torben Ballegaard Sørensen.
“BeoSound 2 is a shining example of how Bang & Olufsen puts the user situation ahead of industry hype. We aim to provide simplicity and clarity in the otherwise swirling sea surrounding Internet music, just as we do in the field of home entertainment” continues Sørensen.
BeoSound 2’s musical experiences take place in close co-operation with BeoPlayer, Bang & Olufsen’s Web music organiser, which can be downloaded free of charge to a computer from the Bang & Olufsen Web site.
BeoPlayer automatically sorts all your digital music by artist, genre, song title and album title, as well as allows you to create your own specially composed play lists. Just drag-and-drop your songs from BeoPlayer to BeoSound 2, and you are on your way out the door.
Two-way communication between BeoSound 2 and the computer allows BeoSound 2’s software to be updated simply and easily. In this fashion, BeoSound 2 endures as an up-to-date and relevant music player, benefiting from the rapid evolvement of the Internet-based music arena.
Additionally, the stainless steel cabinet takes on an appealing patina the more it is used, gaining character from sharing the pocket with keys, coins and the like. BeoSound 2’s robust construction supports Bang & Olufsen’s commitment to quality and ensures a long physical lifetime.
Six pre-recorded music samples are included on the 128 Mb SD memory card that accompanies BeoSound 2. Approximately four hours of tunes may be contained on this size card, and additional cards may be purchased separately.
Furthermore, your digital music can also be moved about in your home with Bang & Olufsen’s Beolink® PC 2, which utilises your computer as a source in a Beolink® system. BeoPlayer again takes care of all file organization, providing you with identical operation whether in the home office, kitchen or on the go.
From 14 June 2004 the product specifications of BeoSound 2 will be changed. To allow customers greater freedom in the selection of memory cards, as from 14 June 2004, BeoSound 2 will be delivered without the standard 128 MB SD card. However, three higher capacity cards may be bought from Bang & Olufsen – 128MB, 256MB and 512MB – although BeoWorld recommends that customers shop around for other more economical, equally-compatible SD cards. A8 Earphones come as standard accessories to use with BeoSound 2 XSD

Often this is because the SD card has been used in another device like a camera.
The card needs to have all hidden files deleted. The BS2 will not do this through simple formatting, so you will need to use a separate card reader.
Some tracks can be missed on a BeoSound 2 Personal Mp3 player when playing an SD card recorded on a BeoSound 4. Newer software on the BeoSound 4 should resolve this.
