EMI T2211 BAND II CONVERTOR
|NOTES||This type of convertor is a universal type not tied to any particular
manufacturers sets. It works by converting the Band III signal down to Band
I and feeding the resultant signal into an unmodified Band I television.
However the obvious advantages - the universal nature as well as the ease
of installations - was often outweighed by problems of interference between
the convertor's output and that of the local Band I channel the the target
T.V. previously used, resulting in paterning on the display.
Being a universal convertor it could not obtain its power from the television set and hance the unit contains its own power supply. However a nice touch is the mains feed-through connector into which the television's mains lead would connect, allwoing the set to be switched on and off via the convertor unit.
By 1958 most people whould already be able to receive Band III, either because they had bought a new set in the past three years or had already upgraded their existing set. Thus EMI's remainders were dumped on the surplus market though under the name "Televoice".
