Abbingdon Music Research LS-77 owner manual Levelling/Speaker Support

Always place the speakers on a rigid and level surface!

4.5 Levelling/Speaker Support

The best surface for any compact speaker is a dedicated stand construction, providing a solid foundation and allowing the proper listening height (high frequency driver at ear height). Dedicated high quality stands are available at your AMR retailer.

As an alternative, the LS-77 may also be placed on shelves, bases or furniture.

This will often restrict the sound quality, though with careful use of some basic techniques and due to the wide ranging adjustability of AMR's speakers it is possible to materially minimise any negative influence.

a)Set the speaker on a solid, rigid level surface using compliant supports (available from your AMR retailer). The surface should be free from resonances. There must me no protrusions or other obstructions in front of the speakers.

b)Place the speakers so that the high frequency drivers are at ear-height and oriented vertically.

c)If necessary the speakers can be placed with the woofer above the tweeter to make this easier to achieve.

d)If necessary the high frequency drivers can be rotated by 90 Degrees. This will be carried by your authorised AMR retailer as it requires disassembly of your speakers.

e)If the speakers cannot be placed with the high frequency drivers at ear-height use placement that elevates the high frequency drivers as close as possible to ear-height. Then use suitable means to elevate either the rear or front edge of the speaker to aim the high frequency drivers main axis at approximately ear height at the listening position.

f)If necessary, adjust both the high frequency and low frequency balance of the speakers (see Appendix A - Adjustment of tonal balance).
