1.1 Interface Overview

The GTP-860’s front panel is designed for ease of

operation. All controls are logically grouped for easy,

intuitive operation. Familiarize yourself with the preced-

ing diagram and read the short explanations of each fea-

ture below. When you finish, you will be well on your way

to enjoying the GTP-860’s convenience and sound quality.

[1] Power Button

Depress the Power button to switch the preamplifier to its ‘Stand-By’ mode. The amber LED in the power button will light up. On the front panel, press any of the input selector buttons [11] to switch the preamplifier on. From the remote control, press the power button [30] to switch the unit on (see remote diagram, page 20). The display will light up indicating which input was selected and the power button LED will turn red.

Pressing the Power switch again will turn the unit OFF completely. The GTP-860 preamplifier uses a memory back-up system to store surround sound trim settings and preset station information for the tuner section. This information is retained for several weeks, even if the unit is switched off completely or unplugged.

Press the Remote Control Power button [30] to switch the unit from Operating to Stand-By mode. Press this button again to switch to Unit On from Stand-By; the last select- ed source will be indicated in the display.

The Power Button LED will light up amber when the preamplifier is switched On, but in Stand-By mode.

NOTE: In Stand-By mode the GTP-860 uses very little power. However, it is recommended that you switch the unit com- pletely off if it is not going to be used for more than a couple of days. Switch off completely by pressing the Power button on the front panel. All lights will extinguish. When the GTP-860 is plugged into the wall current may still be flowwing into the transformer. Only when the GTP-860 is unplugged is all current into the device stopped.

[2] Display Button

The GTP-860 supports RDS PS and RDS RT. With stations carrying RDS information, “RDS” will light up in the

display panel, and the station’s RDS name is automatically displayed (RDS PS).

Some radio stations, which support RDS, also transmit additional information, known as Radio Text (RDS RT). To view this information, use the Display button.

With stations carrying RDS information, the Display button scrolls between three different display modes, each successive push of the button engages the next one of the three modes:

a)In the default mode, the station’s RDS name is displayed, Program Service (PS; normally the station’s calling letters, WXYZ, for instance).

b)From the default mode, press the button once to view Radio Text (RT). This can be additional information such as the presenter’s or program’s name; what song is play- ing, etc. This text scrolls continuously over the 8 alpha- numeric display segments. It takes a few seconds for the tuner to gather the RT information, so immediately after tuning to a station and selecting to view RT the display will indicate “NO TEXT” and default to the station name. If no RT information is available, the display will also show “NO TEXT” for three seconds before reverting to the default mode.

c)Press the Display button from the RT mode to display the station frequency. Press again to return to the default mode (a).

When the Display button is pressed when tuned to a non- RDS station, the display will show “NO NAME” for three seconds before reverting to the default display.

The Display button also has a secondary function: When pressed and held for three seconds, the front panel dis- play will dim. Press and hold the button again to turn the display off, and again to set the display back to its original brightness.

[3] FM Mute/High Blend Button

This button combines two functions; it switches the tuner from Stereo to Mono and disengages the muting circuitry at the same time. The muting circuit will mute the tuner in between radio stations when searching or tuning to avoid tuning noise.
