Alesis M1 T

Surround Sound

32 M1 ACTIVE REFERENCE MANUAL

The use of M1 Actives (or any monopolar speaker) as full-range surrounds would be

useful in the following cases:

• If the surround speakers are just as important as the fronts in achieving a

specialized effect, such as completely mixing the sax in the left rear only and a

flute in the right rear.

• If you know that your mix will always be played back on a monopolar surround

system.

• If the control room is completely damped with sound absorption on all surfaces.

(This renders the reverberant-field generating properties of a bipole/dipole

speaker ineffective.)

* Dolby Surround, Dolby Pro Logic, and Dolby Digital are trademarks of Dolby Laboratories, Inc.
