• Cambridge Audio 340Razur, 12 To setup your speaker configuration, press the OSD button on the remote to activate the On-Screen Display (OSD). Note: You must be connected to a TV/Monitor by Composite or S-Video connections first. Highlight the ‘Speaker Configuration’ menu by using the Volume Up/Down buttons on the remote and press the Enter button: Now move down and by highlighting each speaker in turn and using the Left and Right arrows select from ‘Large’, ‘Small’ or ‘None’ for each speaker: ‘Large’ or ‘Small’ are used to describe each speaker in terms of bass response, they do not necessarily reflect the actual physical size of the speaker.

• Cambridge Audio 340Razur, 340Razur 13 ENGLISH Because the speakers in a surround sound system are usually different distances from the listener the 340R incorporates the ability to apply a variable digital delay to each of the channels so that the sound from each arrives at the same time at the listening position for best surround- sound effect. Each pair of speakers (i.e. Front Left and Right or Surround Left and Right) are subject to the same delay and so must be situated equidistant from the listener. To set the delay times simply measure

• Cambridge Audio 340Razur, 14 The next step is to select each source input in turn on the 340R and tell the unit the type of audio connection you want to use for that source (Analog or Digital input). The 340R remembers this setting individually for every source input and automatically recalls it as and when you change source input. Select the ‘Input Setup’ menu. Highlight each source in turn and select either analog or digital input types (use the Left and Right arrows): Analog inputs will require a stereo phono/RCA to phono/RCA cable connection to the 340R. Digital inputs will require either a 75ohm digital type phono/RCA

• Cambridge Audio 340Razur, 18 Dynamic Range Control This setting controls the dynamic range of Dolby Digital or DTS movie soundtracks by compressing the dynamics in four stages to limit the difference in level between loud and quiet passages in the movie. This can be a useful feature when watching movies late at night for instance. Four settings are possible: DRC=0/4 No Compression (normal full dynamic range playback) DRC=1/4 DRC=2/4 DRC=3/4 DRC=4/4 Greatest Compression (reduced dynamic range playback) DRC can be accessed by the DRC button on the remote, DRC=0/4 etc is displayed, pressing the button again m

• Cambridge Audio 340Razur, 20 Bass Augment can be a useful function with PLII material because this encoding type does not include an LFE Channel. This would normally mean that if all the speakers in your setup were set to ‘Large’, the subwoofer would in fact be inactive (as no bass has been re-directed plus there is no LFE channel). If it is desired to have the subwoofer running with all Large Speakers and PLII encoding, enable Bass Augment for PLII and then set the Crossover point and level by ear. A Sub channel will now
