CANFORD QUICK CHECK TEST DISC
Note: This disc is no longer available. As an alternative, the Canford International Broadcast Standards disc is now being offered at the same price. This has a considerably extended range of test tones, whilst also including the speech tracks that were on Quick Check.
Correct alignment of equipment and recordings is essential to get the best out of any audio system and for when material is passed to other facilities, for example when submitting broadcast tapes, field recordings, or CD pre-masters.
This disc contains 12 tracks of essential technical signals and reference speech recordings to allow operators and technicians to perform basic alignment and quality checks on audio systems. Ideal for a quick check of unfamiliar equipment and acoustics, as well as a source of regular tune-up material.
The test signals used on these discs were specially prepared for Canford Audio by BBC Research and Development Department. Speech recordings were recorded for these discs under carefully controlled conditions by BBC Radio Production Resources with announcer Peter Donaldson in Studio B15, Broadcasting House, London.
Available on Compact Disc in a jewel case, supplied with explanatory notes and usage tips.
