3.2. Connecting the amplifier
Connect the other cable ends to the loudspeaker outputs of your switched-off power amplifier. When using
Speakon® equipped speaker cables you only need to identify the correct channel and connect the cable. If using
two or four pole speaker cables of conventional design, please make sure that the red marked posts of the
speaker are connected to the red marked output of your amp, and the white or black marked posts to the white
or black marked output accordingly.
AMR loudspeakers feature a carefully matched and fine-tuned crossover, to achieve a truly balanced and
smooth frequency response. However, optimising the frequency bands through bi-wiring or bi-amplification can
offer significant benefits. Please consult your authorised AMR retailer for recommendations and demonstrations
and see the Appendix C - Biamplifying the LS-77 for options using AMR equipment.
3.3 Multi-channel set up
The AMR LS-77 Reference Class Professional Monitor is designed to offer the most advanced performance in
both stereo and multi-channel applications, effectively enabling the maximum performance from either of these
formats. When connecting a loudspeaker to a multi-channel system, in general the same guidelines as previously
mentioned in the text above will apply. Because there are many different set up options - from 5.1 to 10.2
channel applications - and due to the fact that loudspeaker positioning will also depend upon the room's particular
shape, please consult your authorised AMR retailer for special applications and placement options.
3.4 Choice of loudspeaker cable
The loudspeaker cable may may have a dramatic effect on sound quality, though in general, quality cable
products will yield a quality result. The LS-77’s are designed to be very neutral, and as such are not extremely
reliant on any one particular type of cable. The choice of cable is as much a factor of matching the cable to the
entire audio system, while also a matter of personal taste and preference. In an all AMR System AMR's
OptiLink Speakon® connector equipped cables are highly recommended.
Always switch
your amplifier off
when making or
breaking
connections.
