OPERATION USING THE T 748 - MAIN MENU ENGLISH ABOUT THE ON-SCREEN DISPLAY (OSD) LISTENING MODE The T 748 employs a simple, self-explanatory system of on-screen display “menus” that will appear on the connected video monitor/TV. These are required during the setup process (and are useful in day-to-day operation), so be sure to connect the monitor/TV before proceeding with the setup.
OPERATION 7.1 Speaker System PLIIx Music PLIIx Movie Front (left and right), Center, Surround (left and right), Back Surround, Subwoofer Front (left and right), Center, Surround (left and right), Back Surround (left and right), Subwoofer NEO: 6 Two-channel recordings, whether stereo or surround-encoded, are reproduced with NEO:6 surround with output to front left/right, center and discrete left/right surround channels plus subwoofer (assuming these are present in the current “Speaker Configuration”).
OPERATION USING THE T 748 - MAIN MENU ENGLISH FRANÇAIS DSP OPTION You can then feed the ZONE 2 jacks to another amplifier or receiver that maybe located in another area of your home or building. With your separate amplifier or receiver selecting the fed signal and with speakers connected, you can then enjoy the zone selected source’s audio signal. Adjust the volume control of your amplifier or receiver according to desired audio level.
OPERATION SETUP MENU SOURCE The T 748 is equipped with eight configurable Sources. A particular Source can be enabled or disabled, renamed, assigned analog and digital audio sources, video sources, A/V Presets among other settings. ENGLISH USING THE T 748 – SETUP MENU NAME A new Name maybe assigned to a Source label. For example, if your BD player is attached to “Source 1”, it is possible to rename “Source 1” to “BD”. There are three sub-menu items under Source Setup.
OPERATION USING THE T 748 – SETUP MENU ENGLISH DIGITAL AUDIO To take advantage of the T 748’s high performance surround and digital audio circuitry, it is advisable that its Digital Audio inputs are selected. FRANÇAIS There are three types of Digital Audio input for the T 748. These are HDMI, Optical and Coaxial digital inputs. A fourth option is “Off” whereby no incoming digital audio signal is selected by the particular Source.
OPERATION SPEAKER SETUP After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your listening environment. MEASUREMENT IS THE FIRST STEP. Connect the microphone jack into the front panel’s MP/MIC input. Place the supplied microphone in the listening position at about the same height as your listening ears.
OPERATION USING THE T 748 – SETUP MENU ENGLISH SPEAKER LEVELS Every surround-sound system requires “bass-management” to direct lowfrequency content from any or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that you correctly identify your speakers’ capabilities. We use the terms “Small” and “Large” (and “Off”) but note that physical size may be irrelevant.
OPERATION NOTES • All speakers must be in their final locations before level-setting. • Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its highest-possible frequency if you are using the T 748’s Subwoofer output. Final subwoofer-level adjustment “by-ear,” using music and film sound material, is frequently useful.
OPERATION USING THE T 748 – SETUP MENU ENGLISH FRANÇAIS ESPAÑOL When devices that support HDMI Control (CEC) are connected, the following modes of operation can be executed via the T 748 or the external device using any of the device’s remote control. Source (On/Off): At “On” setting, the T 748 will automatically switch sources if another CEC device requests a Source change.
OPERATION DOLBY SETUP A DTS audio input can be configured relative to its format as follows Stereo: If the detected audio is of Dolby stereo format, you can default it to one of the following settings - Stereo, PLIIx Movie, PLIIx Music, PLIIx Game, Neo:6 Cinema or Neo:6 Music. Surround: If the detected audio is of DTS Surround format, you can default it to one of the following settings - Stereo, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music or None.
OPERATION USING THE T 748 – SETUP MENU ENGLISH DTS SETUP DTS–ES MATRIX 6.1 In this format, the additional signals of the back channel receive a matrix encoding and are inputted into the right and left surround channels. During reproduction they are decoded to the right, left and back surround channels. FRANÇAIS Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1 format effect can also be achieved from sources with DTS-ES 5.1 signals.
OPERATION ENGLISH USING THE T 748 – SETUP MENU A/V PRESETS SETUP The Vacuum Fluorescent Display (VFD) and On-Screen Display (OSD) can be shown in various ways by navigating through the parameters at the Display Setup menu. Use a combination of [ A/S/D/F ] keys to step through the Display Setup menu items. The T 748’s simple but powerfully flexible system of “A/V Presets” allows you to customize virtually every aspect of your audio-video playback, and recall them with a single key-press.
