DIP SWITCHES
There are ten DIP Switches located on the back of the DFR11EQ. The following table describes the function of each switch. See the DFR11EQ
User’s Guide on the Software CD ROM for instructions on how to set the Device ID.
*NOTE: See the Set Up instructions in the Using the DFR11EQ as a Stand-Alone Feedback Reducer section of this Quick Reference
Guide for instructions and warnings regarding use of the Input and Output Sensitivity DIP switches.
HOLD/UPDATE
UPDATE position... When the HOLD/UPDATE DIP switch is in the UPDATE position (default), the DFR11EQ saves the feedback filters every
time the unit is powered off. When the DFR11EQ is powered on again, the feedback filters will be at exactly the same settings as when the unit was
powered down.
HOLD position... When the HOLD/UPDATE DIP switch is changed to the HOLD position, the DFR11EQ immediately saves the feedback filters
at the current settings. When the DFR11EQ is powered off, any changes made to the feedback filters after the switch was set will be forgotten. When
powered on again, the feedback filter settings will be exactly the same as when the HOLD/UPDATE DIP switch was changed to the HOLD position.
This feature is useful for storing the best filter settings for a sound system.
To store filter settings in the HOLD memory:
1. Set the Hold/Update DIP switch to the Update position;
2. Ring out the room until all fixed filters are set;
3. Set the Hold/Update DIP switch to the Hold position;
4. During the performance, the DFR11EQ will change dynamic filters and deepen fixed ones;
5. After the performance, turn the power off and back on; the DFR filters are restored to the state they were in before the performance.
