Adcom GSP-560 - Manual (Page 8)

THE RIGHT TO A CLAIM AGAINST A COMMON CARRIER CAN BE FORFEITED IF THE CARRIER IS NOT
NOTIFIED PROMPTLY IN WRITING AND IF THE SHIPPING CARTON AND PACKING MATERIALS ARE NOT
AVAILABLE FOR INSPECTION. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED.
The foam cocoon and carton were specifically designed to protect your GSP-560 Even though space is often at a
premium in today’s homes, we recommend that you save the packing materials in case you need to ship the unit
anywhere in the future
2) INSTALLING
The GSP-560 is heavier than you might expect due to the high capacity toroidal transformer and large heat sink
assembly forthepoweramplifiers Astable supporting surface is necessary We won’t go into the endless and mostly
unproven theories about extraneous vibrations and their deleterious effects on audio/video components except to
say that the more massive and firmly anchored the supporting surface is, the less likely you’ll be to experience any
problems.
Proper airflow is important. Don’t block the ventilation slots on the bottom plate and top cover of the unit. The feet
will insure enough air space below the GSP-560 for adequate circulation DO NOT STACKOTHER UNITS ON TOP
OF THE GSP-560. We recommend 4" of open space above the GSP-560 to allow for cooling.
3) SAFETY
Turning off system components before initial installation and connection avoids the nasty buzzes, thumps and other
sounds of electronic distress that occasionally accompany hooking up components Remember to give any power
amplifiers sufficient time to fully discharge their power supplies before you begin your connections. 30 seconds after
turn-off IS usually sufficient.
4~5) LINE LEVEL CONNECTIONS
Patience and common sense will help to avoid almost all of the errors you might make during the initial installation
Rememberto connect LeftChannel to Left Channel and Right Channel to Right Channel, etc. Thejacks on all ADCOM
products follow conventional color coding:
White for Left Channel and Red for Right Channel. Most interconneot
cables observe this general guideline the connectors on each end of the cable are usually color coded.
We’ve received many questions about the sonic attributes of premium interconnect cables We do suggest that you
make sure any cable you use is a “low oapacitance’’ design (Most are ) Your ADCOM salesperson will be happy
to make cost-effective recommendations based on individual component characteristics and system complexity
6) CENTER CHANNEL SPEAKER CONNECTIONS
The “Center Mode” switch ® has three positions. The bottom two, “Wide Spectrum” and “Normai,” are important
here
“Wide Spectrum” sends afull range signal to the center channel speaker Use this position when your center channel
speaker is capable of extended bass reproduction and is acoustically similar to your mam left and right speakers
“Normai” restricts bass output (below 100 Hz) to the center channel speaker and redirects it to the mam left front
and rightfrontfull range speakers Use this position when you’ve chosen asmaller center channel speaker that might
not be capable of extended bass reproduction Under these circumstances, “Normal’’ reduces speaker distortion
and improves center channel clarity
NOTE: The center channel speaker is an essential component In a Dolby Pro Logic equipped home theater system.
It should be placed as close toyourTV screen as is physically possible and must be magnetically shielded to prevent
image distortion and possible damage to your picture tube.
In conjunction with Dolby Pro Logic’s “adaptive matrix” decoding, the center channel speaker improves coherency
by anchoring the soundfield to the screen’s Image Dialog, for example, always appears to be coming from yourTV
regardless of where you’re sitting in the room
