27 Band Automatic Equalizer

OPERATING INSTRUCTIONS

Setup of the EQ1/EQ2 consists of adjusting the EQ curve (either manually or using AutoEQ

TM

), selecting 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 equalization 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 microphones (i.e. microphones connected to the AM8 or other
mixer feeding the EQ1/EQ2), 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
nonvolatile 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.
