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 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.
6.3.9 Auto Volume
The Auto Volume function controls the volume level in a zone in
relation to its environmental noise. Using the Auto Volume control
pane, you can configure and calibrate this function for each zone.
Factory default settings
Dynamic EQ is set to Off.
