Channel B’s controls become active.
Channel B
Channel B of EQD 312 is a duplicate of Channel A. All controls, encoders and LED
indicators found on Channel A are found on Channel B.
REMEMBER: When Channel Master A is engaged, all of Channel B’s controls are
disabled!
Adaptive Hum Cancellation (AHC)
Adaptive Hum Cancellation has been incorporated into the EQD 312 for the express
purpose of reducing 50Hz or 60Hz line noise. The very common audio artifact is typically
caused by ground loops and can be successfully removed by AHC.
Presets
The EQD 312 can store up to four programs. Stored programs can be recalled by
selecting the desired program with the Preset switch located at the left end of the front
panel of the unit. Pressing the Preset switch repeatedly cycles through the four Preset
Positions. Stopping on a program for approximately three seconds causes the stored
program in that position to load and the unit to operate in that Preset mode. (NOTE: All EQ
encoders, controls, and switches with the exceptions of the Store switch and the Preset
switch are disabled when a program is recalled).
STORING PRESETS / PROGRAMS
The Store switch is used to store Programs (Note: Programs cannot be stored if Channel
A HI Q, Channel B HI Q or the Preset switch are in the ON position).
Press and release the Store switch. Notice that the Store switch and the Program 1 LED
are blinking rapidly. You can cycle through all 4 program positions and back to Manual
mode by simply pressing and releasing the Store switch.
Go through set-up of the EQD 312 to suit your requirements. After you have finished, be
sure that Channel A HI Q, Channel B HI Q and Preset are not engaged. To create and
save the current set-up as a program in position 1, press and release the Store switch.
This will cause both the Store switch and the Program 1 LED to blink rapidly. Next, press
and hold the Store switch until the Preset switch lights and the Program 1 LED stops
blinking and remains ON. The system set-up you’ve just completed is now stored in the
Program 1 position and can be recalled by pressing Preset until the Program 1 LED
comes on. Four separate set-ups can be stored and recalled in this fashion.
It should be noted that updating a stored program is only possible if the unit controls have
not been changed. If you want to tweak a stored program, you would have to first restore
the controls to the position they were in when the original setting of the controls was
stored to memory and then make your adjustments.
To clear all stored Presets. Turn the power to the EQD 312 off. Power the unit back up
while pressing the Channel A Master switch. This restores the four Preset positions of the
unit to the factory default setting of zero for all settings and overwrites all stored
information.
