5. VIDEO 1 - VIDEO 4 (AUDIO & VIDEO)
Apart from the audio signal, these inputs will also accept a video signal which will be routed to the Monitor Out sockets (No. 8) for a television or video projector. The Video 1, 2 and 3 inputs also have the option of a Video Composite connection (using the yellow RCA socket) or an S-Video connection (using the Mini-Din connector).
The S-Video standard allows for higher quality video signal transfer when compared to the Video Composite standard. If your video components have an S-Video connector use dedicated S-Video leads to connect them to the T 751 in the same way as described with the Video composite equivalents.
A video signal fed to an S-Video input socket will be available on both the S-Video Monitor Out and Video composite Monitor Out.
VIDEO 1 & VIDEO 2 (AUDIO)
Inputs for the audio playback and video signal from a video device such as a stereo TV, DVD player, satellite cable TV receiver or a Laser Disc. Using twin RCA-to-RCA leads, connect to the left and right ‘Audio Out’ of the video device to these inputs. Using
asingle RCA-to-RCA lead (Video Composite) or S- Video lead, also connect the video output of the video device; refer also to the description of S-Video and Video Composite in section No. 5 of this chapter. VIDEO 1 & VIDEO 2 can be used for video playback only. Use VIDEO 3 or VIDEO 4 if you want to connect a VCR for recording and playback through the T 751.
The optical Digital Input 1 (No. 6) is linked to the Video 1 input. Select Video 1 to hear a source con- nected to Digital Input 1.
The coaxial Digital Input 2 (No. 6) is linked to the Video 2 input. Select Video 2 to hear a source con- nected to Digital Input 2.
VIDEO 3 & VIDEO 4 (AUDIO)
Connections for the audio recording and playback to a VCR or other video recorder. Using twin RCA-to- RCA leads, connect to the left and right ‘Audio Out’ of the VCR to the VIDEO 3 or VIDEO 4 IN connectors for playback. Connect the left and right ‘Audio In’ of the VCR to the VIDEO 3 or VIDEO 4 OUT connectors for recording. Using a single RCA-to-RCA (Video Composite) lead or S-Video lead, also connect the video output of the VCR to Video In (only Video Composite for Video 4) for Video playback. Connect the Video Input of the VCR to Video Out of the NAD T 751 receiver for recording of video signals. Refer also to the description of S-Video and Video Composite above in this section.
6. DIGITAL AUDIO INPUTS
The T 751 has three digital audio inputs to allow for connection of DVD, CD or other digital sources:
GB
Digital Audio Input 1 allows for connection of a digi- tal source with an Optical output. Use a cable termi- nated with a TOS Link connector. This digital input is linked to the Video 1 input.
Digital Audio Inputs 2 & 3 allow for connection of a digital source with a Coaxial digital output. Use a cable with the right impedance, specifically designed for the transfer of digital signals. These digital inputs are linked respectively to VIDEO INPUT 2 and
VIDEO INPUT 3.
7. AUDIO PRE-OUTS / SUBWOOFER OUT
AUDIO PRE-OUTS
The NAD T 751 receiver has five power amplifiers built-in to power all the speakers connected to it (Left, Right, Center, Left Surround, Right Surround). It is also possible to use the T 751 as a pre-amplifier to drive external power amplifiers. This way, you use all the control functions the T 751 provides, such as input select, surround mode, volume, tone controls, etc., but the external power amplifier actually powers the speaker connected to it instead of the T 751’s integrated power amplifier for that channel.
Connect the RCA-to-RCA leads from the Front left and Right, Center, and/or Surround Left and Right Audio pre-out connectors to the external amplifiers. Connect speakers to the external amplifiers.
NOTES:
Never connect the T 751’s speaker outputs and the speaker outputs of an external amplifier to the same speakers. When headphones are inserted the signals from all audio pre-out outputs will be muted.
Before making any connections, check that the T 751 and the power amplifiers it will be connected to are switched off. With volume turned down to a low level, switch power on only after all connections have been made.
SUBWOOFER OUT
Unlike for the full range five channels as described above, there is no power amplifier built-in for an addi- tional subwoofer. The Subwoofer pre-out allows for connection to a sub-bass speaker system with its own external or integrated power amplifier (“active” subwoofers).
NOTE:
When headphones are inserted the signal from the Subwoofer output will be muted.
8. MONITOR OUT
Composite Video and S-Video outputs for connect- ing a TV or Video Monitor to view video sources con- nected to VIDEO 1 to VIDEO 5. Using a Video RCA- to-RCA lead, connect the ‘Video Line In’ on the TV or monitor to the MONITOR OUT.
