Acoustic Energy Loudspeaker AE307 User Manual

							Owner’s manual 
						

							Congratulations on choosing the Acoustic Energy AESPRIT
307, a powerful three-way centre channel dialogue
loudspeaker which features metal diaphragm technology and
is capable of outstanding performance. 
Please take a few moments to read this manual. The advice it 
contains will enable you to get the very best performance out
of your Acoustic Energy loudspeaker.
The AESPRIT 307 utilises metal cone mid and bass drive unit
technology, proven in the AE Reference series. The rigid anodised alloy
cone ensures pure piston action and also acts as a heat sink for the
bonded voice coil. These features provide exceptional clarity,
transparency, dynamics and power handling. The units are housed
within vented die-cast chassis reducing stray magnetic flux to a
minimum and increasing power handling.
The tweeter - or treble driver - is a high-quality neodymium unit with a
silk fabric dome integrating smoothly with the rest of the system.
All drive units are fully magnetically shielded so that the speaker can be
used in close proximity to a TV screen or monitor for AV applications.
The Acoustic Energy AESPRIT 307 loudspeaker uses quality OFC internal
wiring, which enhances detail and transparency. 
Position the AESPRIT 307 either immediately above or below the
television screen, whichever places the speaker nearest ear level when
listening. Line the front of the speaker approximately in line with the
plane of the screen.
Fix the four self-adhesive foam-rubber feet to the base of the speaker to
protect both the surface on which the speaker stands and the underside
of the speaker. The feet also absorb vibration, which is especially
important if placing the speaker directly onto a thin television cabinet.
If placement is on top of the television, be aware that the flat surface
depth may be limited, so ensure the feet are placed accordingly.
When fine-tuning, adjust the levels of the left, centre and right speakers
to give a balanced sound as images pan across the screen.
Positioning Introduction 
						

							Bi-amping
Bi-amping adds a second amplifier to the system. One power amplifier
drives the treble/mid section of both loudspeakers; a second drives the
bass sections. 
Note that the shorting links must be removed.
Failure to do so will result in damaging the amplifiers.
As regards the loudspeakers, wiring for bi-amping is achieved in much
the same way as bi-wiring. Treble/mid amplifier positive (red) terminals
should be connected via the ribbed cable to  the positive (red) HF
terminal on the speaker. Similarly, treble/mid amplifier negative is
connected to the negative (black) HF  terminal on the speaker. Repeat
this process with the bass amplifier and LF terminal pair.
After wiring up
Lower the volume to the
minimum, switch on the
amplifier, select the signal
source and then raise the
volume to the
listening level
required.

FOR FUTURE USE
CENTRE
Check that your amplifier is switched off before installing your
loudspeaker. Failure to do so may result in speaker or amplifier damage.
The diagram illustrates one loudspeaker only.
Conventional
Normal passive wiring requires shorting links to be in place between the
treble/mid and bass sections. The positive (ribbed) cable from the
amplifier positive (or red) terminal should connect with the positive
(red) terminal on the loudspeaker. Similarly the negative (smooth) cable
should connect the amplifier negative terminal (black) to the negative
terminal (black) on the loudspeaker.
Bi-wiring
Bi-wiring separates the bass and treble ground paths in the loudspeaker
and offer sound quality advantages. An extra set of cables is required.
Note that the shorting links are removed between the treble/mid and
bass sections and should be stored for later use if conventional, passive
driving is required.
Two pairs of cables are connected to the amplifier terminals. One cable
of each pair should connect to the treble/mid section and one to the
bass section. The positive (ribbed) cables from the amplifier positive (or
red) terminal should connect with the positive (red) terminals on the
loudspeaker. Similarly the negative (smooth) cables in each pair should
connect the amplifier negative terminal (black) to the negative terminals
(black) on the loudspeaker.
