Adcom GTP-600 - Manual (Page 12)

The ADCOM ADIink'"’ connector duplicates all the separate RCA type preamplifier outputs in one 8 pin DlN-style
connector. Use this connector in place of the RCA outputs only with an ADIink'"" equipped ADCOM multi-channel
power amplifier. The ADIink"^ interconnect cable automatically assures proper channel continuity from preamp to
power amp and reduces the number of interconnect cables needed.
12) SUBWOOFER CONNECTIONS: The Subwoofer jack 0 supplies a line level output for direct connection to the
line input of a powered (self-amplified) subwoofer or the input of a dedicated subwoofer power amplifier. The
Subwoofer output is a mono (L-i-R) output — right and left front information is combined or mixed before it is sent
to the jack.
The Low pass filter switch 0 changes the characteristics of the subwoofer output. The “In” position filters high
frequencies above 100 Hz at a rate of 18 dB/octave. This is called a “low pass" filter in tfiat only low frequency
information is allowed to “pass" through. The “Out" position bypasses the filter to send a full range mono signal
from the subwoofer jack.
It is not good audio practice to send a signal through a series of low pass filters and most self-powered subwoofers
have an adjustable low pass filter at their input. For that reason, we suggest that you use either the GTP-600's
filter OR the subwoofer’s filter but NOT BOTH. Read the subwoofer’s instruction manual for further information.
After that, you may want to experiment to determine the best sounding alternative.
13) REMOTE EXTENSION ACCESSORIES:
ADCOM's remote control accessories can add enormous flexibility when used with the GTP-600.
Optional remote sensors (either the component-styled XR-50011 or the in-wall SPM-500 II) allow you to fully control
the GTP-600 from a number of additional locations in your home. Either sensor plugs into the Remote Sensor
Extension 0 Complete instructions are included with the XR-500 II and SPM-500 II.
The IRA-500 (also optional) repeats infrared command pulses received from XR-500 II or SPM-500 II external
sensors. It should be plugged into either of the Infrared Repeater outputs ©. The triangular end of the IRA-500
should be placed close to the sensor of the non-ADCOM component and then secured with the supplied double
sided mounting tape.
The IRA-500 also resolves the dilemma inherent in setting up a technically complete but non-intrusive home
entertainment system. All of the components can be hidden in custom cabinets or closets. Aside from a TV
screen, the only item that needs to be visible is an XR-500 II or SPM-500 II external sensor.

14) AC CONVENIENCE OUTLETS (Certain models only):
simply call ADCOM’s Customer Service
A) Switched outlets; Make sure that the components plugged into these outlets do not draw in excess of 500
watts. You’ll find the power consumption of most components marked on the rear panel near the power cord
or model number identification.
B) Unswitched outlet: Do not exceed 800 watts. Remember that large power amplifiers can impose substantial
demands on any electrical outlet, especially during “turn on.”
For your information, the proper unit of measure here is the Volt/Amp, abbreviated VA. A Volt/Amp is the AC
equivalent of a watt. However, most people use the term “watt,” so we won’t confuse the issue.
We strongly recommend the use of ADCOM’s ACE-515 AC line enhancer/sequential switcher. In addition to
providing the convenience and safety of surge protected multiple outlets and dramatically superior RF and
EMI filtering, the ACE-515 simplifies system turn-on and turn-off as well. Time delay switching protects your
speakers from the potentially annoying effects of power transients. Check with your ADCOM dealer for
details.
15) AC LINE FUSE: The line fuse is a 1 ampere AGO type. It should be replaced only with a fuse of the same type
and rating. A higher rating or different fuse type will not protect the GTP-600, will void the warranty, and may be
a fire hazard!
This fuse DOES NOT PROTECT the AC convenience outlets.
