AUDIO 3-4 OUT• Connect AUDIO 3 OUT (and/or AUDIO 4 OUT) to correspondingrecording components or audio input ports of compatible sourceslike cassette deck, CD/DVD recorder or outboard audio processors.• The signal present at AUDIO 3-4 OUT is determined by the currentsource selected. There will be no output at AUDIO 3 OUT whenAUDIO 3 is selected. Likewise, there will be no output at AUDIO4 OUT when AUDIO 4 is the active source input. This preventsfeedback through the recording component thereby preventingpossible damage to your speakers.• When configured, AUDIO 3 OUT and AUDIO 4 OUT are the sameassigned ports for Zone 3 and Zone 4 respectively. See also Zoneoutput description below.4 7.1 CHANNEL INPUT• Connect to the corresponding analog audio output of amultichannel source component such as a DVD-Audio ormultichannel-SACD player or external multichannel decoder (disccopy protected formats only allow analog signal transfer). Typically,these sources will produce 5.1-channel output, in which case theSurround Back jacks are left unconnected. The signal present atthese jacks can be heard by selecting Source 7 (7.1 CHANNEL INPUTis defaulted to this Source).• There is no bass-management or other processing (other thanmaster-volume control) available to this 7.1 channel input.• While the multichannel audio output of a DVD/BD player can beconnected to these jacks, using the T 787’s own Dolby Digital andDTS decoding and digital-analog converters via a digital connectionwill usually produce superior results.5 XM MODULE INPUT (120V version model only)With XM radio, there are more than 100 channels of music, news, sports,comedy, talk and entertainment. You will find that the coverage iscontinent wide. The music quality is digital with many commercial-freemusic channels.• Connect XM radio cable to this socket. Follow the instructions thatcame with your XM radio.• Refer also to the “LISTENING TO XM RADIO” segment of the“OPERATION” section.NOTEThe external XM radio is not supplied with your T 787.DAB MODULE INPUT (230V version model only)The T 787 is compatible only with the NAD DAB Adaptor modulemodels DB 1 or DB 2. With DAB, you can receive CD-like qualityprograms without any annoying interference and signal distortion.• Plug-in the other end of the Mini-Din connector from the NAD DABAdaptor module output port into this socket.• Refer also to the item about “LISTENING TO DAB RADIO” segment ofthe “OPERATION” section.NOTEThe external NAD DAB Adaptor module is not supplied with your T 787.6 SOFT CLIPPING• Enables NAD’s proprietary Soft Clipping circuitry on all channels.• At ON position, Soft Clipping gently limits the output of the T 787 tominimize audible distortion should the T 787 be over-driven.• Soft Clipping may simply be left ON at all times to reduce thelikelihood of audible distortion from excessive volume settings.However, for critical listening and to preserve optimum dynamics,you may wish to defeat it by setting this switch to OFF.7 RS 232NAD is a certified partner of AMX and Crestron and fully supportsthese external devices. Check out the NAD website for informationabout AMX and Crestron compatibility with NAD. See your NAD audiospecialist for more information.• Connect this interface using RS-232 serial cable (not supplied) toany Windows compatible PC to allow remote control of the T 787via compatible external controllers.• Refer to the NAD website for information about RS232 Protocoldocuments and PC interface program.8 +12V TRIGGER OUTThe T 787 has three +12V TRIGGER OUT ports (OUT 1, OUT2 and OUT3)that can be configured to supply +12V DC to a linked component orsystem. See discussion on “Trigger Setup” at the “Setup Menu” literaturefor guidelines on how to configure +12V TRIGGER IN/OUT.• Use a 3.5mm mini-jack connector to pass +12 volts at a maximumcurrent of 50 milliamps to an auxiliary equipment such as amultichannel amplifier or subwoofer. The center conductor (hot) ofthe 3.5mm jack is the control signal. The outside conductor (shield)is the ground return-path.• This output will be 12V when the T 787 is ON and 0V when the unitis either OFF or in standby mode.+12V TRIGGER INWith this input triggered by a 12V DC supply, the T 787 can be switchedON remotely from standby mode by compatible devices such asamplifiers, preamplifiers, receivers, etc. If the 12V DC supply is cut off,the T 787 will return to standby mode.• Connect this +12V Trigger input to the remote device’scorresponding +12V DC output jack using a mono cable with3.5mm male plug. The controlling device must be equipped with a+12V trigger output to use this feature.9 IR IN/IR OUT 1-3These mini-jacks accept and output remote-controlled codes inelectrical format, using industry-standard protocols, for use with “IR-repeater” and multi-room systems and related technologies.• All NAD products with IR IN/IR OUT features are fully compatiblewith the T 787. For non-NAD models, please check with your otherproduct’s service specialists as to their compatibility to the T 787’s IRfeatures.IR IN• This input is connected to the output of an IR (infrared) repeater(Xantech or similar) or the IR output of another compatible deviceto allow control of the T 787 from a remote location.IR OUT 1, IR OUT 2• Connect IR OUT 1 (and/or IR OUT 2) to the IR IN jack of a compatibledevice.• Command and control the linked compatible device by directing itsown remote control to T 787’s infrared receiver.IR IN and IR OUT 1, IR OUT 2, IR OUT 3• Connect the T 787’s IR IN to the IR OUT of a compatible device.Connect also the T 787’s IR OUT 1 (and/or IR OUT 2, IR OUT 3) to theIR IN of a compatible device.• With this setup, the T 787 acts as an “IR-repeater” allowing the deviceconnected to the T 787’ s IR IN control or command of the otherdevice linked to T 787’s IR OUT 1 (and/or IR OUT 2, IR OUT 3).IR OUT 3• IR OUT 3 can only function as an “IR-repeater” as described above.IDENTIFICATION OF CONTROLSREAR PANEL9ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
