Why it was a function of the disc player rather than the sound desk I\u2019m unsure, but it amounts to what we would have called \u201cFoldback\u201d in TV studios.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a id=\"post-20146-Alan_Taylor\"><\/a>Alan Taylor<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  That sounds entirely plausible and ties in with the \u2018direct\u2019 &amp; \u2018both\u2019 positions of the switch, together with being grouped with the other Output controls.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  It\u2019s not an abbreviation I\u2019ve come across before and the T.I.s they have for that type of grams deck don\u2019t mention of that control, nor is it shown in the schematic diagrams.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  I understand that the particular unit was originally installed in a radio studio in Cardiff.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hugh Snape<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  AER was the BBC\u2019s abbreviation for foldback. It stood for Acoustical Effects Reproduction and, as far as I remember, was a way of playing music or FX onto the studio floor via the foldback speaker.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Typically used in radio dramas this allowed the actors to hear the FX or music (the SLS was automatically muted when mics were faded up) and also permitted the material to be picked up by the mic(s) if desired.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  As I recall the type A and B desks had a dedicated AER fader.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Direct, Both, and AER, on the gramdeck routed its output to the grams fader, the grams and AER faders, AER fader only.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  All this seem pretty cumbersome today but desks then (at least the BBC designed ones) didn\u2019t have the aux outputs we are familiar with today and so the above is how foldback was achieved.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a id=\"post-20146-David_Plowman\"><\/a>David Plowman<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Think the difference is FB is a &#8216;sniff&#8217; of an FX etc fed into the prog chain direct &#8211; so an artist etc can just hear it. AER is only fed to the studio speaker and picked up via those mics. Useful if say adding an acoustic to the studio mics like say reverb as the effect will get that too. Etc.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hugh Snape<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Yes indeed, though on a modern desk you could achieve the same using a prefade aux.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  NB, I think the AER keys on those RP2\/9\u2019s are really just a hangover from earlier grams. I never remember them being used at BH probably because, as I recall, RP2\/9\u2019s weren\u2019t put in the type A or B Mk 2 studios. But might well be wrong !\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">John Howell<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  AER was primarily for putting a bit of &#8216;space&#8217; around effects played from the gram desks. I remember struggling to make effects on disks more &#8216;distant&#8217; by using this method. Back in the day you were presented with effects recorded close to a mic. just to get a decent recording level and it was up to you to treat it to make it sound distant, there was always the echo room !\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  As to why AER appeared on RP2\/9s, this how P&amp;ID worked, refurbishing a studio started with what was there already and added new facilities but often didn&#8217;t ask what was no longer required.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  eg. The Prompt Cut and its bypass arrangements could have been missed off many TVC &amp; LG studio refurbs going back at least 10 years, I think the only time I used it was as a &#8216;bleep&#8217; inserter for a kids drama.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hugh Snape<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  I remember being at a trade show after I\u2019d left the BBC and seeing a brand new desk on the Calrec stand which was destined for TC. It had every sort of bell and whistle including a large stepped attenuator and other features which seemed rather archaic but which I suppose the Beeb was still happy to pay for . . .\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a id=\"post-20146-Mike_Giles\"><\/a>\n<\/p>\n\n\n\n<br><br>\n<h1>&nbsp;<\/h1>\n\n<br><br>\n<p class=\"western\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-medium wp-image-1061\" src=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall-300x104.jpg\" alt=\"ianfootersmall\" width=\"300\" height=\"104\" srcset=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall-300x104.jpg 300w, http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall.jpg 348w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n\n<br><br>\n<!-- END Footer -->\n","protected":false},"excerpt":{"rendered":"<p>Alan Taylor In the Broadcast Equipment Museum, they have this RP2\/9 grams deck.
