ADCOM GTP-860 OWNER’S MANUAL | 17 [32] Mute Button In all modes, this button is preprogrammed to mute outputs of device. Mute does not affect recordings made using the Tape outputs but will affect the signal going to the Preamp Outputs. When the unit is in mute mode, any adjustment of the Volume Control on the front panel [8] will release the muting, i.e. the original volume level will be resumed. [33] Dynamic Range Button In main mode, this button is preprogrammed to adjust dynamic range of Dolby Digital encoded sources. The d. range button, which can be used only in combination with a Dolby Digital source, incrementally reduces the audio track’s dynamic range in four steps (100%, 75%, 50% and 25%) to allow for comfortable listening under a variety of conditions. The normal or default position is 100%. To adjust the dynamic range, each consecutive press of the d. range button will reduce the value in 25% increments, as shown in the alpha-numeric display section. Although we usually prefer to reproduce a source’s full dynamic range (the difference between very loud and very soft sounds), it may occasionally be desirable to reduce the dynamic range. For example, when playing a movie late at night, loud explosions might wake sleeping family members. Simply turning the volume control down would probably make a whisper in the next scene inaudible. The d. range button solves this dilemma by progressively lowering the volume of loud peaks while increasing the level of softer sounds. [34] Volume Up/Down Buttons In all modes, these buttons change the master volume setting of the GTP-860. In all modes except main, they can be reprogrammed with new commands. The Volume control does not affect recordings made using the Tape and Video, or Tape, Video 3 and Video 4 outputs but will affect the signal going to the Preamp output. [35] Mode Button In main mode, this is preprogrammed to cycle through the surround modes of the GTP-860. Pressing repeatedly will cycle through Pro Logic, Hall, and Stereo, when available. Refer to the Surround Mode description [12] for more information. 18 | ADCOM GTP-860 OWNER’S MANUAL [36] Play Button In CD mode, it is preprogrammed for play with an ADCOM CD player.

[41] Direct Access Keypad (buttons “1” through “10,” and “+10”): In CD mode, buttons are preprogrammed as track access commands for the ADCOM CD player. [42] Test Button Pressing the test button engages the test signal generator to allow for adjustment of all speaker levels, so that each channel can be adjusted for equal loudness at your listening position. The test signal cycles automatically with 3second intervals from Front Left, Center, Front Right, Rear Right, Back Right, Back Left, Rear Left, to Subwoofer in continuous cycles. If an adjustment in setting is made for one of the channels, cycling will pause for 3 seconds after the adjustment was made. Both display panel and OSD show which speaker is being fed with the test signal. Use the cursor down and up buttons to respectively decrease or increase the level for the current speaker. Press the test button again to leave or cancel the test mode, any changes will be memorized automatically. [43] Balance (balance check) Button In main mode, button is preprogrammed to initiate balance check procedure. Even when the GTP-860 is correctly set-up, it may sometimes be desirable to make minor adjustments to suit the material you are listening to. Pressing the bal button allows for direct adjustment of Center, Surround, and Subwoofer levels. Press the bal button to scroll to the next speaker. Both display panel and OSD show which channel can be adjusted. Use the Down and Up arrow buttons to respectively decrease or increase the level for the current channel.
