Page 26: Room Acoustics
Room Acoustics Acoustics Magazine reviewers and audio system owners spend much time critically appraising speakers and other audio compo- nents. Unfortunately, a phenomenon that has a very large effect upon sound is not easily judged or changed. That effect is the ACOUSTICS of the environment in which you are listening. -
Page 27: Benefits Of Equalization
Equalization Benefits Another set of variables is the shape and volume of your listening room. Large rooms require more bass energy to excite waves within them. Small rooms need less energy, but reflect it differently. And then there’s the fact that most rooms don’t have four walls anymore, but open into dining rooms, lofts, cathedral ceilings, etc. -
Page 28: Adjusting The Signal Processing
Adjusting the Signal Processing Adjusting the Signal Processing Equalizing the System Before proceeding on equalizing the system, it is a good idea to make sure everything is connected and working prop- erly. You know how to check connections and here are some reminders specific to The Director, as well as the steps to equalize. -
Page 29: Parametric And Graphic Equalization
Adjusting the Signal Processing Parametric and Graphic Equalization The graphic equalization controls in The Director are se- lected to correspond with the characteristics of wall and ceil- ing speakers and as such are very effective. Graphic controls are the easiest to tune and provide a “graphic” representation of what the adjustments are. -

Adjusting the Signal Processing are found in this range. If accentuated too much (by boosting this control) sounds in the 2500Hz range can seem harsh and fatiguing to the ear due to excessive output by the speaker or because of live, reflective room acoustics. 12kHz —... -
Page 31: A Brazen Plug
Brazen Plug A Brazen Plug For Other AudioControl Products AudioControl started out making graphic equalizers in 1977. Our heritage and design experience grew from a back- ground in professional audio, so we were never quite satis- fied with what was available for the consumer audio market. Since that time, we have continued to expand our product offerings to become a key part of great home audio and video systems. -

Page 34: Installation Of Multiple Units Of The Director
Advanced Topics Installation of multiple units of The Director May you stack units of The Director on top of each other without an air space in between? The Director is a very energy efficient amplifier and emits little heat so air spaces between units, while always helpful, are not mandatory for a background music system. -
Page 35: Level Matching And Gain Controls
Advanced Topics The circumstances where The Director Model D3400 draws maximum power are very rare outside of an engineer- ing lab. Maximum power is using a sine wave input which has at least a third higher energy density than music. This would mean that all channels are operating at maximum, an unlikely situation even during a really fun party. - Page 36 Advanced Topics Commercial noise masking systems rely on “white noise” which sounds remarkably like a bathroom exhaust fan and like the sound of water in a shower-- both of which are louder than the background noise level in the other parts of the house.
