User manual TAG MCLAREN AUDIO 700X7R

[. . . ] To the best of our knowledge TAG McLaren Audio is the only manufacturer to use this sophisticated and elegant system in an audio amplifier. Its advantages are as follows: Excellent stability. All the active components involved are operated under circuit conditions that maximise their bandwidth. This results in greater stability when the negativefeedback loops are closed. [. . . ] · Do not place objects filled with liquids, such as vases, on or near the 700:7r. b e f o r e you start Make sure that all the components of your system are disconnected from the AC supply whenever you change any connection. positioning The 700:7r is capable of consuming approx. 2000 Watts of electrical power during demanding presentations. This results in significant heat being dissipated. Make sure there is adequate ventilation for the amplifier. It is important that the cooling slots in the top and bottom are not obstructed, and there is sufficient space around the unit to allow for the free circulation of air. Avoid operating the amplifier on a soft surface, such as thick carpet, which is likely to block the slots underneath, 1 . Throughout this manual, b o l d print indicates the lettering that you will find on the re ar panel of your 700:7r 10 | set-up remove power Before making any signal connections ensure the amplifier is not connected to the mains supply. signal connection Ensure that the amplifier mains plug has been removed from the wall socket before making loudspeaker connections. Connect your pre amplifier/av processor using good quality analog interconnects. loudspeaker connection Ensure that the amplifier mains plug has been removed from the wall socket before making loudspeaker connections. When making the connection, ensure that the spade terminal is correctly located and the loudspeaker terminal is fully tightened. set-up 7channel set-up For seven channel use the channel bridging switch is in the `off' position. | 11 You will find 7 pairs of loudspeaker terminals on the rear of the unit. For seven channel use, the speakers are connected between the + (red) and -(black) terminals as shown above. Connect the red (+) terminal of the loudspeaker to the red terminal on the rear panel of the 700:7r. In turn connect the black (­) terminal of the loudspeaker to the black terminal on the 700:7r. It is not advisable to change the position of this switch when the amplifier is powered and connected to loudspeakers. No damage to the amplif ier will r esult, but you may apply an unexpectedly high level to the loudspeakers. 12 | set-up Bridging When the 700:7r is operated in bridged mode, two amplifier channels are used to drive each loudspeaker, for greater power output. To use bridged modes of operation you must alter the position of the channel bridging slide switch on the rear of the unit. This has three positions and allows you to bridge just BR and SR to give one extra-powerful channel, or bridge both BR-SR and BL-SL to give two extrapowerful channels. The operation of the LEFT, RIGHT and CENTRE channels is not affected. 6 channel set-up The channel bridging switch is put in the middle position marked "BR+SR" When the BR and SR amplifiers are bridged, the + lead of the speaker cable connects to the BR+ output terminal, and the - lead of the speaker cable connects to the SR+ output terminal as shown. To apply signal to the BR-SR bridged channel use the upper RCA input (marked "In A"). The lower RCA (SR in) is not used. It is not advisable to change the position of this switch when the amplifier is powered and connected to loudspeakers. No damage to the amplif ier will result, but you may apply an unexpectedly high level to the loudspe akers. set-up 5 channel set-up The channel bridging switch is put in the right position marked "BR+SR BL+SL" The BL and SL amplifiers are now also bridged, and the + lead of the speaker cable connects to the BL+ output terminal, and the - lead of the speaker cable connects to the SL+ output terminal, as shown. To apply signal to the BL-SL bridged channel use the upper RCA input (marked "In B"). To apply signal to the BR-SR bridged channel use the upper RCA input (marked "In A"). The lower RCA (SR in) is not used. | 13 It is not advisable to change the position of this switch when the amplifier is powe red and connected to loudspeakers. It will then enter the active state and the blue power LED will glow brightly. [. . . ] The fuse carrier contains a spare fuse; this is the first one that you see when you open the carrier. You cannot open the fuse drawer while the plug is in the socket. There are no user-serviceable parts inside the 700:7r. s e rv i c e The only service you should do to your 700:7r is described on the previous page. All other servicing should only be carried out by one of our authorised service agents. [. . . ]
