azur 751R V2 ENGLISH Analogue audio connections Note: Do not plug in the mains power lead or turn the unit on until all connections have been made. Connect to source equipment using stereo phono cables (stereo 2RCA2RCA). Tape/MD/CDR recorder/players require two sets of stereo phono/ RCA cables, one for recording, one for listening.
HDMI input connections 4K video resolution HDMI (High-Definition Multi-Media Interface) is an all digital connection that can carry both audio and video in one cable. Direct digital transfer of audio and video and support for various types of High Definition video content and high resolution audio make this the best connection type to use. The HDMI inputs can be assigned to the BD/DVD, Video 1, Video 2, Recorder 1, Aux, CD, Recorder 2, Expansion or 7.
azur 751R V2 Three types of analogue video connections can be made to the 751R V2: 1. Composite – Connect with single 75 ohm Video phono cable (RCA-RCA). 2. S-Video – Connect with S-Video cable. 3. Component – Connect with 75 ohm Component video cables (3RCA3RCA) For sources that only support analogue video for best picture quality we recommend making Component video connections, then in declining order of quality, S-Video connections and then Composite video connections.
7.1 preamp out Front input connections If it is desired to connect external power amplifiers, use Phono/RCA leads connected to the 7.1 Preamp Outputs on the rear panel. The front panel Video 3/MP3 input is for temporary connections to video games consoles etc. Remove the cap to access the Video 3 inputs and connect to a video game console or video camera's outputs using stereo phono cables (RCA-RCA) and a Composite video cable. Alternatively, use the 3.
azur 751R V2 Background information The full setup of the 751R V2 is a reasonably simple 3 stage process. The Speaker Setup stage can either be performed manually or via the Audyssey Auto Setup procedure. 1 Front left and right speakers For stereo and multi-channel sound. Stage 1: Speaker setup (Speaker delay, Crossovers and Level calibration, via Audyssey or manually) 2 Centre speaker For dialogue and centre sounds.
Performing the setup cont. Note if you select a 5.1 speaker setup an option appears for SBL/R Assign. You may now choose to use the unused SBL and SBR amplifier channel to Biamp the Front Left and Right channels (Set SBL/R Assign to Biamp) or drive a pair of speakers in Zone 2 (Set SBL/R Assign to Zone 2) or simply leave them unconnected (Set SBL/R Assign to None). For information in Bi-amping and Zone 2 see later sections.
azur 751R V2 The 751R V2 allows level calibration to match the acoustic level between different types/sizes or even manufacturers of speaker that may be being used for each channel. This is achieved by adjusting the relative level of each speaker. This can be done manually through the 'Level Calibration' menu in the OSD or automatically, see the following Audyssey auto setup section of this manual.
2 Audyssey 2EQ Room EQ This is a more sophisticated version with a longer second stage that measures the frequency response of all of your speakers three times at three different points in the room and then calibrates and equalizes them to optimise the sound for your actual listening environment (Room EQ). To perform Audyssey autosetup with no Room EQ simply select Audyssey autosetup from the menu. To perform autosetup and Room EQ select Audyssey autosetup & 2EQ.
When the auto setup of the 751R V2 is completed successfully, the 751R V2 displays a 'Measurement Complete' screen and then shows the Advanced Audyssey Setup screen as per following section. If you have just perfomed Audyssey autosetup & 2EQ you will see 2EQ is enabled plus you can now enable Audyssey Dynamic EQ and/or Dynamic Volume as well (if desired).
Assigning video inputs Source setup The 751R V2 has 6 HDMI inputs (one of which is on the front) and two outputs. HDMI is a fully digital audio/video system for picture and audio in digital format for best possible picture quality. The next step is to select each source input in turn on the 751R V2 and tell the unit: HDMI outputs on Blu-ray, DVD players and Set-top boxes also often support higher resolution formats including progressive scan types.

The options are: Scaler Assign BD/DVD VIDEO 1 VIDEO 2 VIDEO 3 Recorder 1 Aux CD 7.
Surround sound modes cont. Known also as DD (3/3) or DD 6.1, an enhanced form of Dolby Digital. On top of the discretely encoded 5.1 channels DD EX provides an extra 6th channel (Surround Back, giving 6.1) matrix encoded into the rear surrounds for greater image depth and more solid sound localisation behind the listener. DD EX requires a DD EX encoded disc. DD EX is backwards compatible with DD 5.1 decoding.
azur 751R V2 Use with Macs No extra drivers are required. With the 751R switched to USB Audio 1.0 the 751R will work with the native Mac OS-X 10.5 (Leopard) or above Audio 1.0 driver and accept audio up to 24-bit/96kHz. With the 751R switched to USB Audio 2.0 the 751R works with the native Mac OS-X 10.5 (Leopard) or above Audio 2.0 driver and can accept audio up to 24-bit/192kHz. Use with Linux For most distributions of Linux with the 751R switched to USB Audio 1.

azur Audio Return Channel The 751R V2 supports an Audio Return Channel (ARC) function from TVs that also support this function (which must feature an HDMI1.4 input and have actually implemented the ARC feature, see your TVs manual). ARC allows a TV to send audio back down its incoming HDMI lead to the 751R V2's HDMI A output socket. This function allows the 751R V2 to play back the audio from a TVs built-in terrestrial cable or satellite tuner whilst you watch it's picture. 1.
and Vol buttons to make You can use the Volume knob or the Vol changes to the picture or press the Pic.Adj. button again to move to the next item. Adjustments are available for Brightness, Contrast, Saturation, Sharpness and Y/C Delay. A second feature of the Picture Adjustment button on the unit's front panel is setting the output resolution for the scaler (this can also be done in the OSD see earlier section). If the front panel (not remote) button is pressed and held for approx.
751R V2 Bi-amping Bass Augment can be On or Off separately for DD/DTS or Dolby Pro Logic II/ IIx/Neo:6 operation. If you are running a 5.1 (or less) speaker setup, the 751R V2 allows for bi-amping of the front left and right channels. It will be seen in the Speaker Configuration menu that with the Decode mode set as 5.1 a Bi-amp On/Off item appears.
Thus it is possible to listen to one source and record another. Selection of the Recorder 2 outputs source is done via the Record 2/Zone 2 Output select menu in the OSD as follows. Record 2/Zone 2 output select Select the rec.2/Zone 2 Output Select menu from the main OSD menu. Rec.2/Zone2 Output Select Recorder 2 : BD/DVD Zone 2 : Off Return I/O Highlight the Recorder 2 item and use the ◄ and ► buttons to scroll through the sources. Whichever you select will be sent to the Recorder 2 outputs.
751R V2 Using the 751R V2 with an IR repeater system Using Zone 2 with the built in SBL/SBR amplifier outputs If desired the 751R V2 can be mounted in a suitably well ventilated cabinet and an IR repeater system used to control the unit remotely. In the On-Screen Display select the Speaker Setup menu.
With this configuration you can now control Zone 2 from the main room by using the main or Zone 2 handsets as supplied (see later section). If it is desired to remotely control Zone 2 and the sources in it from Zone 2 itself an additional (not supplied) IR repeater system should be used, choose one with an Emitter (modulated) type output suitable to connect to the Zone 2 IR emitter In (contact your dealer for details).
azur 751R V2 To turn off Zone 2 simple press Zone 2 followed by the Standby/Off button again. To select Tuner in Zone 2, press Zone 2 followed by the Tuner button. Do this again to switch from AM to FM or vice versa. To select other sources in Zone 2 press Zone 2 followed by the desired source button. To select the same source as the main room's, press Follow Main. To change the volume is Zone 2 press Zone 2 followed by the volume up or down buttons (or volume knob).
