WHAT’S IN THE BOX
Packed with your T 748 you will find
•An AM loop antenna
•A FM ribbon-wire antenna with balun
•A detachable mains power cord
•Measurement microphone for auto calibration
•AVR 4 remote control with 2 AA batteries
•ZR 7 zone remote control with 3V CR2025 battery
•Owner’s manual in CD-ROM
SAVE THE PACKAGING
Please save the box and all of the packaging in which your T 748 arrived. Should you move or otherwise need to transport your T 748, this is by far the safest container in which to do so. We’ve seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!
INITIAL SETUP
Before you make the first connection to your T 748, you should have the arrangement of your listening room/home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital questions of loudspeaker placement and listening/viewing positions is beyond our scope here.
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within 25 feet/8 meters, between the T 748’s front panel and your primary listening/viewing position - this will ensure reliable infrared remote control communications. The T 748 generates a modest amount of heat, but nothing that should trouble adjacent components. It is especially important that sufficient ventilation be provided.
DEFAULT SOURCE SETTINGS
The following table lists the default SOURCE settings. Note that the Audio input settings show both digital and analog audio input. Digital input will always take precedence over analog audio input even if both are present.

For Video output, select the highest quality video format available on your TV/Monitor and utilize this for your Monitor OUT connection from the T 748 to the TV/Monitor. For T 748, this should be HDMI with the other choice being Composite video output.
To modify the above default settings and for a better understanding of source setting and combinations, please refer to the item about “SOURCE SETUP” in the “USING THE T 748 - SETUP MENU” segment of the “OPERATION” section.

ATTENTION!
Please make sure that the T 748 is powered off or unplugged from the mains power source before making any connections. It is also advisable to power down or unplug all associated components while making or breaking any signal or AC power connections.
1FM ANTENNA TERMINAL
•Connect the supplied lead-type FM antenna to the FM antenna input. Extend the lead. Experiment freely with your antenna placement and orientation until you get the clearest sound and lowest background noise. Fix the antenna in the desired position by using thumb tacks, push pins or any suitable means.
AM ANTENNA TERMINAL
The AM loop antenna supplied with the T 748 (or a suitable replacement) is required for AM reception.
•Connect the supplied AM loop antenna to these terminals. If an external AM antenna is used, make connections to the AM and GND terminals in accordance with the instructions supplied with the antenna.
•Testing different positions for the antenna may improve reception; vertical orientation will usually produce the best results. Antenna proximity to large metal objects (appliances, radiators) may impair reception, as will as attempts to lengthen the wire to the loop.
•Refer also to the item about ASSEMBLING THE LOOP ANTENNA at the LISTENING TO AM/FM RADIO section of the OPERATION page.
2AUDIO 1-2/VIDEO 1-2/S-VIDEO
•These comprise the T 748’s other sets of principal input. Connect these S-Video, composite video, and analog audio input ports to the corresponding output ports of source components such as DVD players or cable/satellite boxes.

4AUDIO 3 IN/OUT
•Connect AUDIO 3 OUT to the corresponding analog audio input of a recording component such as a cassette deck, CD recorder or to an outboard audio/video processor. Connect AUDIO 3 IN to the component’s corresponding analog audio output connectors.
•The signal present at the AUDIO 3 OUT is determined by the source last selected via the front panel Source keys or the AVR 4’s input select keys with the exception of Source 3 or Source 4. If the default settings are maintained for both Source 3 and Source 4 (analog audio input is AUDIO 3) and both their respective digital audio input is set to“Off”, there will be no output at AUDIO 3 OUT when Source 3 or Source 4 is selected. This prevents feedback through the recording component thereby preventing possible damage to your speakers.
5COMPONENT VIDEO INPUT
•Connect the Component Video Input to Component Video output of compatible source components, typically a DVD player, BD player, digital cable box or other applicable components.
•Be sure to observe consistency in connecting the Y/Pb/Pr jacks to the corresponding sources.
