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 th

No speaker switching is provided on the amplifiers as this invariably will cause some degradation of the signal, however slight. If it is necessary to switch speakers we recommend that the main pair be wired directly to the amplifier wherever possible and that only the ‘extension’ speakers be switched. With both models it is possible to reduce the value of output fuse fitted in the amplifier in order to provide the best protection for both the speaker and amplifier. See page 7 for full details.

Always ensure that the volume control on your amplifier is set to minimum before starting these procedures. Bi-wiring your loudspeakers Bi-wiring improves the sound of your system because it divides the high and low frequency signal currents into separate speaker cables. This avoids signal distortions arising from the high and low frequency currents interacting with one another within a single cable, as in conventionally wired systems. You will need: Speakers – with four input terminals each: th

MONO LINK 6. The P75 can be adapted to provide two mono loudspeaker outputs from a single input. Pull out the U-link 8 supplied and use it to connect the MONO LINK sockets 6 together. Utilising one P75 power amplifier per loudspeaker will enable you to bi-amplify bi-wireable loudspeakers. This is particularly beneficial for top quality stereo installations with a separate preamplifier, or for the left, centre and right channel loudspeakers in a five speaker Dolby Pro Logic™ or Dolby Digital™ sys

< Are all the channel-indicator LEDs on the front panel green? Refer to the table on page 10 if you see other colours. Hum on an amplifier output If you have a “hum” coming from one of the speakers, please check the following items. < Does the hum originate from a ground loop caused by an aerial, satellite dish or cable supply (if the aerial is disconnected, does the humming stop)? Please contact your dealer or aerial contractor for further advice. < Ensure that the interconnect and speaker lead
