DaytonAudio DSPB Series, Руководство пользователя

Страница: 26 / 47

A. Input – Inputs 0 and 1 will correspond to the left and right channel of any audio input. This could
be could through an aux jack on the DSPB, or using the KAB21 5v3’s Bluetooth streaming (if both
inputs are present, inputs will mix)
B. Gain Controls – These controls are set up to hardware controlled. AUX_ADC_# blocks connected
to each volume control correspond to the potentiometers on the DSPB. The number in the
volume block is the slew rate time constant NOT volume. It is recommended to keep it at 12.
a. It is recommended to make gain controllable with hardware, but these could be
changed to a slider type of control.
C. EQ Section – SigmaStudio has many possibilities for this section, available by navigating through
the Tree Toolbox and paying special attention to the filters section. The parametric EQ found in
Filters > Second Order > Multichannel allows for visual adjustment of filters and is what we use
here as it is the most user friendly, but there are many other ways to achieve EQ. Click the blue
icon in the block
to adjust the PEQ.
a. Note: You might need to reflash your board by hitting the “Link Compile Download”
button to hear the results of adding a new filter in the PEQ mode.
b. Results with this PEQ can be dramatic. Take caution to avoid overloading speakers.
c. Warning – Read the warning at the beginning of section 3 about this block.
D. Crossover Section – This section is preconfigured for a test bench set of speakers, but it is fully
customizable by clicking the blue icon in the block . This will bring up the appropriate
menu.
E. Delay Section – You might find it useful to have a delay block to time align your woofers with
your tweeter. In this case, the woofer sits further back from the tweeter, so we put a delay on
the woofer. Press ‘samples’ in this block to switch the representation to milliseconds. Please
note that this will affect your phase relationships.
F. Output Section – This might need changed depending on how you have wired your speakers.
This example uses one board for the left channel, and one board for the right channel. DAC0 and
DAC1 represent the outputs of the DSPB, and DAC2 and DAC3 represent the outputs of the KAB
board. It could also be configured that one board is woofers, one board is tweeters.
