Adcom THX GFA-7000 - Manual (Page 5)

DESCRIPTION OF UNIT
O RR, LR, R, C, L Inputs
The audio inputs for the GFA-7000 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; Left (L), Center (C), Right (R), Left Rear (LR), and Right Rear (RR).
To insure that the performance designed into the GFA-7000 is preserved, you should use the
highest quality audio cables possible. There are many cables which are Home THX® certified,
color-coded and specifically designed for this application. Your Adcom dealer can help select
the best cable for your needs. (See CONNECTING THE GFA-7000 for more information).
O RR, LR, R, C, L Outputs
The GFA-7000’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 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).
Pin connectors are not recommended for use with Home THX® equipment. (See CONNECTING
THE GFA-7000 for more information).
O
DB-25 Multichannel Audio Input Connector
Input connections may be made with the optional DB-25 computer-type connector, which
is a Home THX® certified option when your Home THX® controller is provided with a similar
output connector. Using this type of connecting cable would override the need to use the RCA-
type inputs (O). This mode of connection retains the same high level of signal transfer,
simplifies the job significantly and insures automatic, correct connections to all channels.
