1 Power On/Off	7 Control Bus
Switches the unit on and off.	In - Allows un-modulated commands from multi-rooms systems or other
	components to be received by the unit.

2AC power socket

Once you have completed all connections to the amplifier, plug the AC power cable into an appropriate mains socket then switch on. Your amplifier is now ready for use.

3Loudspeaker terminals

Two sets of loudspeaker terminals are available, A (main loudspeaker terminals) and B (secondary loudspeaker terminals). Both sets of speakers can be turned on and off independently. Connect the wires from your left channel loudspeaker to the LEFT + & - terminals, and the wires from the right channel loudspeaker to the RIGHT + & - terminals. In each case, the red terminal is the positive output and the black terminal is the negative output.

Care should be taken to ensure no stray strands of wire short the speaker outputs together. Please ensure that the loudspeaker terminals have been tightened completely to provide a good electrical connection. It is possible for the sound quality to be affected if the screw terminals are loose.

Note: When using one pair of speakers, use speakers with a nominal impedance of between 4-8 ohms. When using two pairs of speakers, use speakers with a nominal impedance of between 6-8 ohms. Please also note that when multiple speakers are connected across the amplifier’s outputs, the load (as seen by the amplifier) is reduced. This will make the amplifier work harder, and hotter!

4Dip-switches

Used in conjunction with custom installation (C.I.) systems. Refer to the ‘Custom installation’ section for more information.

Front Panel IR - Set to ‘On’ for normal operation.

Control Bus Passthru - Turns on/off looping of Control Bus signals from Input to Output.

Reserved - Not used.

5IR (Infrared) Emitter In

Allows modulated IR commands from multi-room systems to be received by the amplifier. Commands received here are not looped out of the Control Bus. Refer to the ‘Custom installation’ section for more information.

Out - Loop out for control bus commands to another unit. Also allows the 740A to control some Cambridge Audio units.

8Pre Out

Connect these sockets to the inputs on an external power amplifier(s) or active subwoofers etc.

9Tape/Rec In/Out

Connect to a tape deck or to the analog output sockets on a MiniDisc, portable digital music player or CD recorder using an interconnect cable from the recorder's Line Out sockets to the amplifier's Tape In sockets.

The Tape Input circuit of the 740A is a "monitor" type, different from the other 7 inputs. For the 7 normal inputs, the source selected for listening to will be sent out of the Tape Out for recording. The source currently being listened to and (optionally) recorded is then shown on the front panel display.

However, when the Tape Input is selected a solid circle will appear beside TAPE MON indicating that the Tape Input is now being listened to with a different source being sent out of the Tape Out for recording. The recording source is also shown by a solid circle by the selected input and can be changed by pressing the other source buttons. To switch Tape Monitor off, simply press the Tape Mon input select button again, toggling this function off.

This feature is most useful when using 3-head analog cassette decks which allow the signal being recorded to be played back live off tape (via a 3rd head) whilst it is simultaneously recorded. It is then possible by toggling the Tape Monitor input on and off to compare directly in real time the original and recorded signal so that adjustments to the recording parameters of the tape machine can be made (consult the manual of your 3-head analog cassette deck for full details).

10 Inputs 1-5

These inputs are suitable for any 'line level' source equipment such as CD players, DAB or FM/AM tuners etc.

Note: These inputs are for analog audio signals only. They should not be connected to the digital output of a CD player or any other digital device.

6A-BUS™ Ready / Incognito Ready™ multi-room outputs

PSU - Connect an Incognito PS5 to supply power to the connected multi- room keypads/speakers.

Keypad 1/2 - Connect one or two Incognito 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.
