[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.
