search mode. When tuned accurately to a station, “TUNED” will light up in the display.

[6] Tune/Preset Button

The Tune/Preset button toggles between the Preset and Tune mode. When Preset mode is selected, “PRESET” lights up in the display area. Refer to the Tuner Up/Down button [5] description for more information.

[7] Display Window

The display area shows all vital information when the unit is operational.

[8] Volume Knob

The Volume control adjusts the overall loudness of the signals being fed to the preamplifier outputs. Unlike con- ventional controls, the GTP-860’s volume control doesn’t have a start or end position. Volume can also be adjusted from the remote control using the Master Volume Up or Down buttons [34]. The Volume control does not affect recordings made using the Tape, Video 3 and Video 4 outputs but will affect the signal going to the Preamp Outputs. The volume level is indicated in the display panel when it is being adjusted, and after three seconds the display defaults to its previous status. Volume setting can range from -61dB to +18dB.

On the remote control, press the Mute button [32] to temporarily switch off the sound to the Preamp outputs and headphones. Mute mode is indicated by “MUTING” flashing in red in the display area. Press Mute again to restore sound. Mute does not affect recordings made using the Tape, Video 3 and Video 4 outputs but does affect the signal going to the Preamp Outputs.

[9] Headphone Output/Video 5 Input

A 1/4” stereo jack socket is provided for headphone lis- tening and will work with conventional headphones of any impedance. The volume and tone controls are operative for headphone listening. Use a suitable adapter to con- nect headphones with other types of connectors such as 3.5mm stereo ‘personal stereo’ jack plugs. Inserting a headphone will automatically turn off the signals from the Preamp Outputs, and set the listening mode to Stereo.

NOTE: Head phones are only LF RF output. If listening to 5.1 material center channel should be turned off.

REMEMBER: Listening at high levels can damage your hearing. The video five input is located on the front panel to sim- plify connection of a camcorder or a video game console. To select video five, push the corresponding front panel button in the input selector section.

[10] Surround Backs Button

Pressing this button engages ADCOM’s proprietary 7.1m²™ decoding algorithm. The 7.1m²™ decoding process mixes the signals from the left surround and right surround chan- nels to derive two unique signals sent to each back output. The benefit of our 7.1m²™ decoding process is enhance imaging between the surround speakers and the creation of a more diffuse ambient sound field. The 7.1m²™ pro- cess has the same benefits when compared to other matix decoding as stereo signals have over mono signals. The 7.1m²™ process can also be used to drive your surround back speakers when you are listening to an externally decoded DVD audio or SACD multi-channel disc. Due to the varying nature of film soundtracks and music, you may prefer to activate or deactivate the surround back chan- nels. For example, Dolby Digital 5.1 and DTS soundtracks benefit greatly from the addition of the 7.1m²™ process- ing. Prologic soundtracks on the other hand provide a mono surround signal track, which yields a less satisfying experience when using the surround back channels.

The level of the Surround Back channels can be adjusted in the same manner as the other channels, either through the On-Screen-Display (OSD) or with the Bal. or Test func- tions from the remote control. Be sure to experiment to find the balance that best suits your taste.

[11] Input Selector Buttons

These buttons select the active video and audio input for the GTP-860. The source that is currently selected will be shown in the front panel display and the LED in the source button will be red. The currently selected source signal is sent to the main preamp outputs after processing and the video 3, video 4, aux and tape outputs. If an input has both digital and analog input capabilities the GTP-

860 will give priority to an existing digital signal, and in the absence of a digital signal will default to the analog connection. Video signals associated with an input give priority to s-video sources over composite video signals.

The video one and video two inputs also have component video switching capabilities. This component video
