CEQ1/1 und CEQ1/1BB
EQ Status (EQ In/Out)
- Bypasses the equalizer and low cut filter of the EQ1. This is useful for A/
B comparisons between the equalized and unequalized systems.
Low Cut Filter (In/Out)
- Bypasses the low cut filter of the EQ1.
Pop Suppress Threshold
- Allows adjustment of the amount of DPS action. Threshold range is ­
40dB to 0dB. A dynamic display of the amount of DPS activity is included in this screen to help in
the adjustment process.
Display Contrast
- Allows the contrast ratio of the LCD display to be adjusted to accommodate
different viewing angles.
Auto Equalize...
- Initiates the AutoEQ TM process. Note that the Target Curve/Target Input Source
used for the AutoEQ
TM
process is the one that has been selected by the Adjust Target Curve menu
item. If the SELECT button is pressed, the AutoEQ
TM
process will begin. First, the Pink Noise Level
menu item will be displayed. Use the UP and DOWN buttons to adjust the noise level to an appro­
priate measurement range. Prompts on the display will indicate when the noise level is adequate.
The SELECT button is pressed again to start the actual AutoEQ
TM
. The Checking Band screen will
then be shown, and will indicate how far along the AutoEQ
TM
process is. At the end of the process,
the display will revert to the Auto Equalize... menu. Remember that the SAVE button must be pressed
after the AutoEQ
TM
process to store the new EQ curve to permanent memory.

EQ IN
- Provides the balanced, RF protected line level input into the CEQ1/1.
EQ THRU
- Provides an output directly in parallel with EQ IN. Note that if EQ IN is used unbalanced,
EQ THRU will also be unbalanced.
REF MIC IN
- Provides the balanced, RF protected reference mic input into the CEQ1/1. +15V
phantom power is provided to this input.
EQ OUT
- Provides the balanced line level output of the equalizer.
LecNet TM (RS-232) SERIAL PORT
- Provides access to and control of some of the operational
features of the CEQ1/1. The port is compatible with the serial port of a PC, or other controllers with
RS-232 type serial ports. For hardware interconnection and software details, see Appendix 1,“Se­
rial Port Hardware and Software”.
EXPANSION IN/OUT
- Connects the CEQ1/1 to other LecNet
TM
compatible devices. The Expan­
sion connection to the CEQ1/1 is only necessary if the device is used with a computer. The CEQ1/
1 Expansion Out port should be connected to the last LecNet
TM in the chain (see Figure 2 above).
PWR IN
- Connects to the CH40 power supply to provide power for the CEQ1/1.
