If you want to get going in a hurry, first make sure your POWER-Q is correctly patched into your
system. There are two main tasks the POWER-Q will perform: equalizing the tonal balance of the
system and eliminating feedback.
5.1 EQing AN ACOUSTIC ENVIRONMENT: QUICK INSTRUCTIONS.
There are three basic methods of equal-
izing a sound system with the POWER-Q: Automatic Room EQ, Real-Time Analysis, or by ear.
Automatic Room EQ. Make sure you have a reference mic positioned correctly and plugged
into “Ref A” on the back of the POWER-Q (very important for optimal results). Select #1 (“AUTO-
MATIC ROOM EQ”) from the MAIN MENU. Follow the on-screen instructions. Your system will be
analyzed and the EQ adjustments in the POWER-Q will be made in 10 seconds per channel.
Real-Time Analysis. Alternatively, you may elect to play pink noise through your speak-
ers and adjust the Graphic EQ to balance the frequency response. To do this, first make sure you
have a reference mic positioned correctly and plugged into “Ref A” on the back of the POWER-Q.
Then select #4 (“REAL-TIME ANALYSIS”) from the MAIN MENU, press the “MORE” button and
turn on the pink noise independently for Channel A. Use the superimposed Graphic EQ sliders to
make additional adjustments. Repeat the procedure for Channel B.
Equalizing By Ear. You won’t need to plug in a reference mic to EQ your system by ear.
Select soft key #2 (“GRAPHIC EQ”) from the MAIN MENU. This will display the graphic EQ
screen, one channel at a time (you may select which channel with a soft key). You may adjust
individual filters using a combination of left/right arrow keys and the data wheel.
In addition to or instead of the Graphic EQ, you may affect system equalization with the POWER-Q
parametric EQ. This is accessed by selecting MAIN MENU option #3, “FBX AND PARAMETRIC
FILTERS,” and playing an audio source through your sound system and the POWER-Q. Twelve
filters and a high and low pass filter are available for each channel. These filters are accessed using
the up/down arrow keys and can be set to parametric (“PARAM”) using the data wheel. The data
wheel and left/right arrows set the frequencies, filter widths, and filter depths of all filters. Any changes
made to the parametric filters will add to the overall EQ of the system, including graphic EQ settings.
5.2 EXTERMINATING FEEDBACK: QUICK INSTRUCTIONS.
1. Once your room is equalized to your liking (or you may elect not to equalize and proceed
directly to feedback control, though we don’t recommend this), set up your microphones and
acoustic instruments in the positions where they will be used.
2. If you are using your POWER-Q in a 2 channel system, turn the power amp to zero gain for one
channel. This will allow you to set FBX Filters for the other channel.
3. Set all other controls for your sound system at the settings that will be used for performance.
Select soft key #3 (“FBX AND PARAMETRIC FILTERS”) from the MAIN MENU. The POWER-
Q defaults to seven fixed FBX, three dynamic FBX and two parametric filters, and has up to 12
total filters available for each channel. (This means that using parametric filters for room
equalization by changing these defaults reduces the number of FBX filters available for feed-
back control.)
4. Press the MORE button until you see “TURB-” on the screen. Press the adjacent soft key.
5. Highlight “Automatic Setup” with the arrow keys.
6. Raise the master gain of your mixer until feedback is just starting, then press ENTER on the
POWER-Q front panel.
7. The POWER-Q will automatically raise its output gain and set filters, until either all available
FBX filters are set, or until the first dynamic FBX filter is set. Then the POWER-Q will reduce
its output gain to its original level.
8. Repeat this procedure for the second channel, turning down the power amp for the channel just
filtered, and turning up the gain for the second channel.
(This is just one scenario for setting FBX filters. Please refer to Section 11 for additional details.)
