We hope that you will enjoy many years of listening pleasure from it. The 740A is based on our award-winning amplifier topology as seen in our 540A and 640A models, further developed and enhanced for this new higher end model as part of our on-going development programme. The 740A features three separate transformer secondaries for the left and right power amp channels and preamp, with separate rectifiers and PSU's allowing dual mono operation of the left and right power amplifiers. [. . . ] This control affects the level of the loudspeaker output, the pre-amp output and the headphone output. It does not affect the Tape Out connections. The Volume control is also used in navigating the 740A System Configure menus on the front panel display. Please refer to the `Operating instructions' section of this manual for more information on some functions of these buttons. & 7 Input select buttons Push the appropriate input selection button to select the source component that you wish to listen to (highlighted by a solid circle on the display). The signal selected is also fed to the Tape Out sockets so that it may be recorded. The input should not be changed whilst recording (but the recorded signal can be checked using the tape input Tape Monitor). 8 Display LCD used to control the 740A. Please refer to the `Operating instructions' and `Amplifier setup' section of this manual for more information. 9 Bass and Treble Press to release and rotate to allow subtle adjustments to the tonal balance of the sound. 6 azur Remote control The 740A is supplied with an Azur Navigator remote control that operates both this amplifier and Cambridge Audio Azur CD players. Insert the supplied AAA batteries to activate. The functions relevant to the amplifier are as follows: 740A ENGLISH iPod compatibility To make use of the iPod functionality, the iPod dock must be connected to `Input 4'. The 740A remote can also control the basic functions of Apple iPod models when mounted in Cambridge Audio's iPod docks, Apple's Universal Dock or other docks compatible with the Apple Remote. Refer to your dock's instruction manual on how to make connections. To use the Azur remote to control the docked iPod, hold down the Input 4 button whilst pressing one of the following buttons: Standby/On Switches the amplifier between On and Standby mode. Numerical buttons 1-8 Press to change the input source to the amplifier. Button 6 toggles Tape Monitor on/off. Play/Pause Press to play the iPod, press again to pause play. Bright Adjust the backlight of the front panel display; bright, dim or off. Mode Skip Press once to skip forwards or backwards one track. Mode Input Input Input Press to switch between Volume and Balance modes. Mute Mutes the audio on the amplifier. The mute mode is indicated by MUTE appearing and the volume level being replaced by two flashing dashes in the display. Press again to cancel mute. Input Input Input Input Input Volume Increase or decrease the volume of the amplifier output. Mode The following functions can be optionally used to control Cambridge Azur range CD players: Vol Open/Close Opens and closes the disc tray. Vol Play / Stop / Pause Press the relevant button to play, stop or pause the CD. Skip Right Skip - Press once to skip forward by one track on the CD. Press and hold to skip forwards through tracks. Repeat Random Remain Left Skip - Press once to skip backward by one track on the CD. Press and hold to skip backwards through tracks. Search Press and hold to search within the selected track. Right button to fast forward, left button to rewind. Repeat, Random, Remain Refer to the `Operating instructions' section of your CD player manual for information on the functions of these buttons. 7 Connections When designing our amplifiers we have tried to include features that allow you to connect your system in various ways. The inclusion of features such as Pre-Out and Speaker B connections mean that you can flexibly configure your system depending on your requirements. Speaker B connections The Speaker B connections on the back of the amplifier allow for a second set of speakers to be used (i. e. The Speaker A/B button on the front panel allows this second set of speakers to be switched on and off. Note: When using two pairs of speakers, use speakers with a nominal impedance of between 6-8 ohms each minimum. Basic connection The diagram below shows the basic connection of your amplifier to a CD player and a single pair of loudspeakers. 740A Manufactured in an ISO9002 approved facility This device complies with part 15 of the FCC Rules. [. . . ] When CAP5 detects clipping the volume will be automatically reduced down until CAP5 detects an undistorted output. It is possible to disable the clipping detection feature by pressing the CLIP DT button to off when in the 740A System Configure menu. Note: Disabling the clipping detection is not advised as this feature has been added deliberately to protect the amplifier and loudspeakers. 3. Overvoltage/overcurrent detection Indication - The display flashes "OVERLOAD". Mode Volume Description - CAP5 offers V/I protection by constantly monitoring the output transistors to keep them working inside their Safe Operating Area (SOA). [. . . ]
