Description of Unit
Rear Panel
Inputs (1)
The audio inputs for the GFA-7700 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 L (Left), Center, Front R (Right), Surround L (Left), and Surround R (Right). To insure that the performance designed into the GFA-7700 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-7700for more information.)
Outputs (2)
The GFA-7700’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.) (See CONNECTING THE GFA-7700 for more information)
DB-25 Multichannel Audio Input Connector (3)
Input connections may be made with the optional DB-25 computer-type connector. Using this type of connecting cable would override the need to use the RCA-type inputs (1). This mode of connection retains the same high level of signal transfer, simplifies the job significantly and insures automatic, correct connections to all channels.
