The Ampex Stereo Center provides a convenient grouping,
on a single panel, of all the controls necessary to maximum
stereo listening enjoyment from any source. Whether
the stereo source selected is from magnetic tape,
stereo phono, or the Stereo Center's own integral Stereo
radio tuner, the control functions which are provided
automatically assure the proper matching, equalization,
and balance of the input signals.
As shown in the functional diagram, the desired signal
source is determined by pushbutton selection. If a monophonic
(single channel) signal is selected, the Stereo-Single
button is depressed so that each of the amplifier/speaker
systems receives an identical input, and the resulting
reproduced sound appears to come from a point midway
between the two speakers.
