Inputs
The audio inputs for the GFA-7400/7300 are through high-quality, gold-plated RCA jacks to
minimize high-frequency losses, noise, etc. They will accept standard RCA-type plugs, one for
each of the five channels; Front Left, Center, Right Front, Left Rear, and Right Rear. To insure
that the performance designed into the GFA-7500 is preserved, you should use the highest
quality audio cables possible. There are many cables which are color-coded and specifically
designed for this application. Your Adcom dealer can help select the best cable for your needs.
(See CONNECTING THE GFA-7400/7400 for more information).

Outputs
The GFA-7400's connections to the loudspeakers are made through high-grade, 5-way,
gold-plated binding post terminals. There are two terminals for each speaker, which are colored
RED for the positive (+) output and BLACK for the negative (-) output.
The GFA-7300's connections to the loudspeakers are basically similar; there are two
terminals for each speaker, which are colored RED for the positive (+) output and BLACK for the
negative (-) output. The high-grade gold-plated binding post terminals on the GFA-7300 are
however, different. These connectors easily accept stripped bare wires or pins. To use spade lugs
it is necessary to remove the black molded plastic guide block that fits over the binding posts. To
remove, take out the two screws at the top and bottom of guide block. Store the guide block and
screws for future use.
The binding posts will accept a variety of connector types; the most secure and prevalent of
these is the "U"-type spade connectors (at least 0.25" wide and maximum width of 0.57"),. The
terminal will also accept bare wire (up to AWG10) and "banana" type plugs (single or dual). (See
CONNECTING THE GFA-7400/7300 for more information).
