The Tsunami’s
built-in 7-band equalizer (EQ) will help you get
great sound from any speaker.
Some CV adjustments are obvious (e.g., cutting
frequencies not within the speaker’s range), while others can be tuned to your
personal preference.
Since Lance did not
specify the size of the speaker he is using, we will refer to our 35mm x 16mm
speaker for this explanation.
First, according to its specifications, the
speaker is able to reproduce a frequency range from 250Hz to 13kHz, which is
typical for small speakers.
To start using the
EQ, set CV 153 (Equalizer Control) to 7 to enable the user-adjustable setting.
Then adjust the values in CVs 154-160 (all defaulted to 128), which act as
sliders to boost or cut the frequency range so you can maximize speaker
performance.
Values from 0 to 127 reduce the output from -12db to 0db, and
values from 128 to 255 increase the output from 0dB to +12dB.
CV 153 also
allows you to enable preset cut/boost levels that are configured for various
speaker sizes and types.
For this example, we’re going to apply the
user-adjustable setting so we can alter the sound to our personal preference.
CV 154 controls the
62Hz frequency band, which is too low for our 35mm x 16mm speaker to physically
reproduce (its lowest frequency is 250Hz).
So we’ll set this to 0 so the
speaker will not cause any distortion.
Likewise, CV 155 controls a frequency
that is too low for our speaker (125Hz), so we’ll also set it to a value of 0.
CV 156 controls the 250Hz frequency band, which is the starting threshold of
the speaker’s capabilities.
We can boost this a small amount, so set CV 156 to
175.
The rest of the CVs (157-160) are in the speaker’s frequency in range
as well, so boost these to adjust the sound to your preference.
Try
different settings and listen for what sounds best to you.
Record your
changes so you don’t forget the settings you liked.
Adjusting these
frequencies will help you get the most out of the speaker’s strengths and
provide the ultimate tone control.

behind sound and has tips for speaker installation. You can also watch our EQ demonstration video.
