USING THE T 743

You may operate the T 743 receiver from its front panel or via the HTR 2 remote control. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure also to read the section, "Front Panel" above.

SELECTING SOURCES

With the HTR 2’s remote's [Amp] device selected, the remote’s numeric-key section directly selects the receiver’s inputs, plus the internal tuner ([Tuner), Tape Monitor ([Tape]), and multichannel input ([Ext. 7.1/ 5.1]) refer to the red labels directly above each key.

•When an audio-only source (CD, DISC, TUNER) is selected, the most recently-selected video signal remains selected, until another audio-video input is selected

•When you change sources, the VFL will display the new input in its primary display.

•A newly selected input's listening mode (Stereo, EARS, Pro Logic II, etc.) will revert to the mode to which it is configured on the <Input Settings> line of the setup menu, unless the incoming signal is a Dolby Digital or DTS source, in which case the input will be set automatically to the appropriate decoding mode.

ADJUSTING THE VOLUME

Use the HTR 2 remote's <Volume up/down> keys to adjust the "master volume" of the T 743, raising or lower all channels together. Note that:

•A momentary keypress will change the master volume by 1 dB increments; if you hold down <Volume up/ down> the master-volume change will "run-on" until the key is released.

•The T 743's OSD will show the volume setting as a line graphic with a numeric display above in dB relative to the reference level.

Since recordings vary considerably in overall average level, there is no imperative to listen at any particular master-volume setting. A setting of -20 may sound "as loud" from one CD or DVD as -10 does from another.

•If muting has been activated (below), adjusting master-volume via the HTR 2 remote or the front-panel knob automatically releases the mute function.

•The T 743 will power-up from Standby mode at whatever master volume setting was last used; however, if the prior setting was greater than –20 dB the T 743 will power up to –20 dB. This prevents inadvertently beginning a session at excessive volume.

MUTING THE SOUND

Use the HTR 2 remote's <Mute> key to silence all channels completely. Muting is always available, regardless of source or listening mode selections. Note that:

•Cycling through Standby or powering off does release muting; the T 743 will return from Standby with muting off if Standby was invoked with muting on.

•Changing input or listening-mode selections does not release muting.

•Adjusting the master-volume upward via the HTR 2 or the front-panel knob automatically releases the mute function.

LISTENING TO RADIO

The T 743’s internal AM/FM tuner offers very high quality sound from radio broadcasts. Note that reception and sound quality will always be dependent to a degree on the type of antenna(s) used, as well as proximity to the broadcast origin, geography, and weather conditions.

ABOUT ANTENNAS

The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the ‘balun’ included adapter, and should be fully extended to form a “T”. This folded-dipole antenna will usually work best oriented vertically, with the arms of its “T” full outstretched and arranged perpendicular to the origin of the desired broadcast. There are no ‘rules,’ however, and experimenting freely with antenna placement and orientation may yield the clearest sound and lowest background noise. In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If radio listening is important to you, consider consulting an antenna installation professional to optimize your system.

The supplied AM ‘loop’ antenna will usually provide adequate reception. However, an exterior AM antenna can be used to improve reception; consult an antenna professional for more information.
