Keypad 1/2 - Connect one or two Incogntio A-BUS KP10 keypads (or other A-BUS compatible keypads) using CAT5/5e cable. Incognito AS10 Active Ceiling Speakers can also be connected here. IR - Four IR outputs for remote control of source equipment. Please refer to the ‘Multi-Room’ section of this manual for more information on connections and set-ups.
CONNECTING 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. The following diagrams are designed to make connection easy. Tape connection The diagram below shows how to connect the amplifier to a tape recorder or other source with a record and monitor connection.
540A/640A V2.0 Integrated amplifier Speaker B connections Pre-Out connections The Speaker B connections on the back of the amplifier allow for a second set of speakers to be used (ie speakers located in another room). The Speaker B button on the front panel allows this second set of speakers to be switched on and off. The Pre-Out sockets are for connecting to the input sockets of a power amplifier or active subwoofer.
FRONT PANEL CONTROLS azur 640A Integrated Amplifier Volume 4 Bass 7 Treble 8 Balance Protection Standby / On 1 1 2 Phones Speaker B Direct 3 5 6 Standby/On Switches the unit between Standby mode (indicated by dim power LED) and On (indicated by bright power LED). Standby is a low power mode where the power consumption is less than 10 Watts. The unit should be left in Standby mode when not in use. 2 Infrared sensor Receives IR commands from the supplied Azur remote control.
540A/640A V2.0 Integrated amplifier 6 Direct This control gives the audio signal a more direct path to the power amplifier stage of your amplifier, bypassing the tone control circuits for the purest possible sound quality. 7 Bass and Treble These controls allow subtle adjustments to the tonal balance of the sound. In the central position these controls have no effect.
REMOTE CONTROL CUSTOM INSTALLATION (C.I.) USE The 540A/640A V2.0 is supplied with an Azur Navigator remote control that operates both this amplifier and Cambridge Audio Azur range CD players. Insert the supplied AAA batteries to activate. The functions relevant to the amplifier are as follows: The 540A V2.0 and 640A V2.
540A/640A V2.0 Integrated amplifier MULTI-ROOM The Azur V2.0 amplifiers feature Incognito ReadyTM / A-BUSTM Ready outputs, allowing multi-room capability. One or two amplified keypads (and an external PSU power supply) can be plugged into the amplifier (using Cat5/5e cable and RJ45 plugs) to provide multi-room audio in one or two secondary rooms or zones. The keypads are powered by an external PSU via Cat5/5e cables and no mains connection is required in the secondary rooms.
CAP5 - FIVE WAY PROTECTION SYSTEM Cambridge Audio has developed a proprietary protection system to ensure reliability and a long life to its amplifiers. This protection system comprises of five main protection methods: amplifier is working harder. If the amplifier is mounted in a cabinet or the ventilation slots are obstructed the over temperature detection may activate/reactivate after a short listening time. 1. DC detection Remedy - User related fault.
540A/640A V2.0 Integrated amplifier 4. Short circuit detection Indicator - Unit has switched off during operation, protection LED flashes constantly in bursts of four. Description - During power up from Standby CAP5 performs a check on the loudspeaker terminals to see if a short across the terminals has been accidentally introduced. If the resistance measured across the loudspeaker terminals is too low the unit will stay in Standby mode until the fault has been removed and Power up is re-attempted.
TROUBLESHOOTING There is no power There is a loud buzz or hum Ensure the AC power cord is connected securely. Check turntable or tone arm for ground and connection lead fault. Ensure the plug is fully inserted into the wall socket and is switched on. Ensure no interconnects are loose or defective. Check fuse in the mains plug or adaptor. Ensure that your tape deck/turntable is not too close to the amplifier.
