RECORDING NOTES 67
without one or two rehearsals, especially if the recording equipment is located in the same room.
As a matter of fact in the recording of commercial records three waxes are commonly cut. though strangely enough it is usually the first one which is eventually placed upon the market. Experience shows that you will almost certainly get the best recording from a musical standpoint when your subjects are not actually aware that recording is in progress. So soon as they realize that their efforts are being committed to a recording disc they become "stiff." This is an argument in favour of arranging amplifier and recording turntable in separate rooms.
If the recorder is employed for selections from radio programmes the ordinary procedure is followed except, of course, that the monitoring loud speaker can in this case be in the same room, since no microphone is present. Radio music may be used as a background for microphone performance providing the set be wired up properly.
Aluminium or similar metallic records require a cutting lubricant. Some recording discs are previously waxed, but most are supplied dry, and a small tin of grease included in the equipment.
Vaseline will usually be found adequate for lubricating aluminium, although somewhat heavier and cleaner recording can be obtained by the use of a trace of paraffin, which in engineering is well known to be the best cutting lubricant for aluminium. Whatever oil or grease is employed it should be carefully removed before playback is attempted, as otherwise the point of the fibre or thorn needle will rapidly be spoiled and the needle itself will slip the grooves. A rag moistened with methylated spirit will serve for removing any traces of grease, etc.
Recording Faults. If the amplifier is giving too great a volume the amplitude or ;' swing" of the cutter may be too much, and the grooves will come so close together as to throw the needle during replaying. The obvious cure for this is to reduce the volume, or the tracking device may be modified (in some of the systems at all events) so as to widen the pitch of the spiral-.
An alternative method is to weight the pick-up although
