6.0 E4 System Setup

6.3.8 Dynamic EQ

The Dynamic EQ control panel provides an on/off control to enable/disable Dynamic Equalization in the current zone.

Dynamic EQ should only be used in either of the following conditions:

The system contains extended bass or a FreeSpace® 3 speaker system.

A user interface is being used to control the volume and no autotransformers are being used on the speaker line. When autotransformers are used, the system cannot accurately monitor the output level of the system, and as a result, cannot provide the appropriate response for the current listening level.

Factory default settings

Dynamic EQ is set to Off.

Dynamic EQ compensates for a perceived loss of bass response at low listening levels. Based on the current output level of the E4 system, additional bass and high frequency will be added.

For Dynamic EQ to operate correctly, make sure the hardware is connected properly:

An Auto Volume or Standard wall plate must be connected to the WALL PLATE CONNECTION input connector.

The speaker(s) must be directly wired to the ZONE OUT connector.

DO NOT USE AUTOTRANSFORMERS: DO NOT use an auto transformer on the speaker line to adjust the speaker volume. Dynamic EQ will not operate properly with this added component.
