Title
Preferred Voltage and Impedance Values for the Interconnection of Audio Products
Consumer Electronics Association
Publication Date:
Jul 1, 1974
Scope:
This Engineering Bulletin recommends preferred voltage and
impedance values for inputs and outputs of generally available,
mass produced, audio products and accessories. The purpose of these
values is to guide manufacturers in the design of their products so
as to facilitate the interconnection of products of different
manufacturers.
The values are also intended as a guide for the manufacturers of
integrated systems whose equipment has input and output connections
which permit the addition of other products or accessories. The
values, wherever possible, have been chosen to minimize changes in
apparent sound output level when switching functions. The values
are also intended to prevent gross inequities between products of
different manufacturers that may result in either objectionable
distortion due to overload or inability to develop sufficient sound
output due to lack of gain.
Accepted industry test methods are to be used and good
engineering practice followed in applying these values. Value
changes will occur as dictated by advances in technology.
Establishes preferred voltage and impedance values for inputs
and outputs of generally available, mass produced, audio products
and accessories. These values guide manufacturers in the product
design in order to facilitate the interconnection of products of
different manufacturers and permit the addition of other products
or accessories to integrated systems which have input and output
connections.
