Adcom GTP-860 - Manual (Page 15)

[23] External 5.1 Analog Inputs
Inputs for the multi-channel audio signals from an exter-
nal decoder, such as an SACD or DVD-Audio player with
integrated decoder. Use two twin RCA-to-RCA leads to
connect the decoder’s front left and right ‘Audio Outputs’
to the Front left and right inputs, and the decoder’s
Surround left and right outputs to the Surround left and
right inputs. Use a third twin RCA-to-RCA lead to connect
the decoder’s subwoofer output to the Subwoofer input
and the decoder’s Center channel output to the Center
channel input. Make sure to follow color coding of the
plugs to ensure that both Center and Subwoofer are con-
nected correctly; for instance, use the red plugs at either
end to connect the center channel and the white plugs for
the subwoofer channel.
[24] Digital Audio Inputs
The GTP-860 has six digital audio inputs to allow for
connection of DVD, CD or other digital sources. Three
inputs are optical and three are coaxial.
Use a cable with the proper impedance specifically
designed for the transfer of digital signals.
[25] AC Power Cord
After you have completed all connections to the amplifier,
plug the AC line cord into a “live” wall socket.
[26] 12V DC Trigger
To facilitate remote turn-on and turn-off of other compo-
nents (power amplifiers, for example), this 3.5mm mini-
jack provides a constant signal (12 volts DC) whenever the
GTP-860 is fully powered. When the GTP-860 is turned off
(via the front panel switch) or placed in standby mode
(via the “power” button on the remote control), the jack
has no output.
[27] Voltage Switch
The GTP-860 can be configured for either 120V or 230V
operation using this switch. Extreme caution must be used
when changing the voltage of the unit, as an incorrect
voltage selection will cause severe damage to the unit.
See your dealer or contact ADCOM for more details
regarding the operation of this switch.
International Setup Procedure
Changing the video output between NTSC and PAL:
— Press to momentarily hold ‘MEMORY’ + ‘VIDEO 1’ keys
at the same time.
— The VFD display will indicate the current video system
for three to four seconds and then return to normal
display function.
Changing the AM stepping frequency between USA
10KHz and Europe 9KHz:
— Press to momentarily hold ‘EXT5.1’ + ‘VIDEO 3’ keys at
the same time.
— The VFD display will indicate the current AM stepping
frequency for three to four seconds and then return to
normal display function.
NOTE: We strongly recommend the use of our surge suppresser/
line conditioners, the ADCOM ACE family of products, for sys-
tems with substantial amplifiers and many source components.
The ACE products relieve the GTP-860 from handling large cur-
rent surges, while they protect your entire system by filtering
and conditioning the AC current. In addition to the numerous
heavy duty AC outlets of the ACE-315, the ACE-615 includes
sequential power-up and power-down modes to minimize
“thumps” whenever you turn your system on or off.
[28] IR Input
The IR input allows hook up of an external IR sensor that
sends IR information to the microprocessor in the GTP 860.
This feature can be very useful if the GTP 860 is placed
behind a non transparent door or is used with an after
market remote control system.
