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.

1. Turn on the system. The Power light on the left front panel

should be blue .

2. Connect to this specific unit of The Director over the

network by entering its unique IP address into a browser
(Firefox, Safari, Internet Explorer are preferred).

3. Make sure the unit is turned on and turn off signal sense in

the Operation page on the browser. On the front panel all
zone status lights should start red and then turn to blue.
If any are not blue, check the Operation page to see if you
need to unmute any zones.

4. Play pink noise through the system into the zones you are

going to adjust. If needed, there is a pink noise audio file at
www.audiocontrol.com. Search for “pink noise”. The sig

-

nal is playing through The Director when the LED’s level
meter on front panel responds to the volume.

5. Assuming you have wireless network access, now grab your

trusty real time analyzer (RTA) and go into the zone you
wish to adjust.

6. Place the microphone in the middle of the area of listening

at the height of the typical listeners head.

7. In general, use the equalizer controls to lower peaks in the

frequency response first. Peaks obscure the surrounding
sounds and lowering the peaks will unleash overshadowed
sounds. There is more information in the next section on
equalization and AudioControl has factory training, called
Train in the Rain where we explore this subject in depth.

8. You can save different settings to different memories and

see which one the clients like. Their taste may be different
than yours.

Processing

Note:

For the absolutely

best results, the equalizer

controls on The Director D3400

should be adjusted with a real time

analyzer such as the AudioControl

Industrial SA-3052. Visit www.

analysis products.
