Quick Start

This section explains the procedure for using the iEQ Series EQs for tuning the left and right front of
house speakers in a live sound system�
Using the iEQ in AFS Normal Mode
Use this method when you do not intend to initially ring out the sound system before use� This is the
fastest and easiest way to utilize AFS�
1. Configure the iEQ for AFS Normal Mode operation within the Power-Up Mode menu as
described in the "Power-Up Modes" section of this manual�
2. Set all controls as follows:
• Both AFS buttons = Off (LEDs off)�
• Both TYPE V™ NR buttons = Engaged (LEDs on)
• Both EQ BYPASS buttons = Disengaged (LEDs off)
• Both INPUT GAIN controls = 0dB
• Both LOW CUT buttons = Engage these buttons (LEDs on) as long as you do not have
a low cut filter engaged in an active crossover, loudspeaker management processor, your
amplifier(s), or powered speakers� If you do have a low cut filter engaged somewhere in the
signal chain, post iEQ, leave these buttons disengaged (LEDs off)�
• Both PeakStopPlus
• Both RANGE +/-15 buttons = Engaged (LEDs on)
NOTE: Whenever amplifiers are powered on, be sure to reduce audio levels at the power
amplifiers when changing the setting of this switch as it may generate an audible transient�
• All EQ Frequency Band sliders = Flat (center detent)
3. For best performance, set the gain structure of the sound system� This is beyond the scope
of this manual, but there is much information about this process in books and on the
internet� This is when you will determine where the iEQ's INPUT GAIN controls need to
be initially set (they may require further adjustment after equalizing the sound system as EQ
changes may change the output gain of the iEQ processor)� This is also when you will set the
PeakStopPlus
®
dedicated limiters, the limiters within a loudspeaker management processor, powered speakers
with built-in limiters, or any limiters post iEQ, set the iEQ's PeakStopPlus
controls to the "OFF" position�
4. Using a reference CD, a known and trusted vocal mic, or a real time analyzer and calibrated
microphone, EQ the sound system to taste�
5. Press and release each AFS button until they are both lit yellow�
This completes the iEQ setup process�
LIMITER controls = OFF
