SONAMP DSP 2-150 MULTI-CHANNEL POWER AMPLIFIER INSTRUCTION MANUAL
Parametric EQ
All Sonance DSP amplifier models feature a 10 band parametric
EQ. Adjustments made to the EQ will be displayed on the Output
Frequency Response graph. We strongly suggest not adjusting the
EQ without proper measurement equipment.
EQ On/Off
Turns each of the 10 parametric EQ filters on and off.
EQ Frequency Hz
Enter the frequency in Hz that you would like to adjust.
EQ-Q
This setting determines the width of the adjustment range. The
lower the number the wider the bandwidth. The higher the number
the narrower the bandwidth.
EQ Gain +/-dB
The level of each parametric adjustment can be set +/-12dB.
Careful adjustment of the EQ Gain is necessary to prevent damage
to the speakers. Always increase the level as little as possible.
The first choice should always be to reduce the output to achieve
the target frequency response.
Output Frequency Response Example Image
This graph reflects the changes made below.
The above EQ image shows EQ4 ON at 500Hz, the Q is set to 3 with
a -6dB gain, creating a gradual dip in the lower midrange.
EQ9 shows ON at 3000Hz, the Q is set to 10 with a -6dB gain,
creating a sharp dip in the midrange.
EQ10 shows ON at 10000Hz, the Q is set to 1 with a +4dB gain,
creating a very gradual slope in the high frequencies.
Limiter
The limiter operates as a brick wall limit on the output of the
amplifier. The limiter drop down menu has -3dB, -6dB and -12dB
options. The maximum outputs for each of the models:
All of the above output power ratings are when connected to an
8 ohm load.
Delay
Delay is shown in Milliseconds, Feet and Meters. You can make an
entry in any of the three fields and the other fields will be calculated
automatically.
The minimum delay is .01 milliseconds, the maximum delay is 25
milliseconds.
This function is useful when compensating for distance between
satellites and subwoofers for instance.

IMPORTANT: ONLY MODIFY THE EQ SETTINGS TAB IF YOU HAVE A
STRONG UNDERSTANDING AND EXPERIENCE WITH MANUALLY
CALIBRATING PARAMETRIC CURVES AND HAVE THE NECESSARY
TEST EQUIPMENT. IF NOT, IT IS STRONGLY RECOMMENDED THAT
YOU DO NOT MAKE ANY ADJUSTMENTS ON THE EQ SETTINGS
TAB. ONLY USE THE PRE-PROGRAMMED DSP CURVES AVAILABLE
ON TAB 2. NEVER MAKE ADJUSTMENTS ON THIS TAB BY EAR.
