CEQ1/1 und CEQ1/1BB
5. Operating Instructions
Setup of the CEQ1/1 consists of adjusting the EQ curve (either manually or using AutoEQ TM ), select­
ing the low cut filter status, and adjusting the DPS system.
1) The desired EQ curve should be set first. With the EQ1, and EQ curve may be set manually
either from the front panel display and controls, or using a PC or compatible. The EQ2 may only
be set up using a PC. When set up from the front panel display and controls, the Adjust EQ
Curve menu option is used. Cut or boost may be set for each frequency band, and then the
SAVE button should be pushed to store the new EQ curve in nonvolatile memory. If a PC is used
to adjust the EQ curve, simply adjust the EQ band sliders to the desired cut or boost level. Use
the File/Download option to store the resulting EQ curve in nonvolatile memory.
If the AutoEQ
TM
process is used, a few preliminary items should be taken care of. If the equaliza­
tion will be done using the reference microphone, the reference microphone should be placed
centrally in the listening environment. If the equalization is to be performed with system micro­
phones (i.e. microphones connected to the AM8 or other mixer feeding the CEQ1/1), the
microphone(s) should be moved into the listening environment. Choose the Auto Equalize...
menu option and press SELECT. The Pink Noise Level sub-menu prompts for an appropriate pink
noise level to be set. The EQ1 will indicate when the pink noise level is adequate. Press the
SELECT button again, and the Checking Band sub-menu appears. The actual AutoEQ
TM
is now
started, and progress will be indicated on this menu. At the conclusion of the process, the
menu will revert to the Auto Equalize... option. The AutoEQ
TM
process using the PC is similar, and
initiated using the AutoEQ/Start menu option. After the AutoEQ
TM
process is complete, use the
SAVE button (or File/Download menu option on the PC) to store the new EQ curve to nonvola­
tile memory.
2) If the Low Cut filter is desired, use the Low Cut Filter menu option.
3) Set up the DPS system using the Pop Suppress Threshold menu option. Adjust the threshold
value until breath pops are minimized.
The system is now ready for use.
Resetting the EQ1 to Factory Defaults
If the Up and Down buttons are both pushed while the power is turned on, the EQ1 will be returned to
factory default condition. Factory defaults are as follows:
1) Stored EQ curve is reset to flat.
2) User Target curves 1-3 are reset to Factory curves 1-3.
3) Pop Suppress system is set to off.
4) LCD display contrast is set to the factory default.
5) Operational mode is set to Local.
