 In the early 1950s the EMI BTR 2 became available (right); a much improved machine and generally liked.It became the standard in recording channels (rooms) for many years, and was in use until the end of the 1960s.The machines were responsive, could run up to speed quite quickly, had light-touch operating buttons, forward-facing heads (The BTR 1s had rear-facing heads which made editing difficult), and were quick and easy to do the finest editing on.
