DSPM48 Digital Audio Processor Software Instructions（II）

Don't be intimidated by those complicated English words. Let's explain how to use this software in plain English.

Step 1: Get connected and pick the right path. Open the software and check the button in the top-left corner to see if it's the green "Connected". If it's gray, it means the computer isn't linked to the machine yet; just click the "Search" button next to it to find it.

Once connected, you need to know which channel you’re adjusting. Look at the top row of labels:

• In A/B/C/D: Where the audio signal comes in. For example, click In A to adjust the sound for channel A.

• Out 1–8: Where the audio signal goes out to the speakers. Click the corresponding output number to adjust sound for that speaker.

Step 2: Manage the volume (bottom-left corner).

After you select a channel, look for the "Gain" control in the bottom-left corner.

Push it up to make the sound louder, or pull it down to make it quieter. Usually, you can just leave it right in the middle at 0. If it's too noisy, just slide it down a bit.

There is also a "Phase" button down there. Don't mess with it normally. Only click it if you feel the bass is missing or sounds weak and soft. Just give it a try to see if the bass becomes punchier.

Step 3: Assign tasks (The Crossover in the middle).

This is called the "Crossover". Basically, it just assigns tasks to the speakers.

●High Pass: This means "Highs only, no bass". It's usually for small speakers to stop the heavy bass from blowing them out.

●Low Pass: This means "Bass only, no highs". This is specifically for the subwoofer.

●OFF: This means "Give me everything". If you are using those big floor-standing speakers, pick this one to let them play the full sound.

Step 4: Adjust the Tone (Equalizer at bottom right)

This is the most important part, just like adding seasonings when cooking.

• Numbers on the panel: Think of them as different "flavors."

For example:

◦ 100Hz = low end / bass (like kick drum)

◦ 1000Hz = main vocal range

10000Hz = bright, crisp high-end / metallic tones 

• Gain: This is how much you "add" of that frequency.

Turn the gain up if you want more vocals;

turn down the high frequencies if it sounds too harsh or piercing.

• The large black frame in the middle:

It shows a curve. You can drag the points on the line up or down with your mouse.

As the curve changes shape, the sound will change accordingly.

Step 5: Save Your Settings (Scene on the left)

Once you’re happy with the sound, look for the Scene section in the middle-left area.

Choose any number (for example, 1), then click Save.

Next time you turn on the device, just select this preset 1 and click Recall — all your settings will be restored instantly, no need to adjust everything again.

If you don’t save the sound you worked hard on, it will be lost when you power off.

Here’s the simple workflow summary:

First, connect the device in the top-left corner.

Then select the speakers using the Out buttons at the top.

Push the sliders in the bottom-left to adjust the volume.

Drag the curve in the middle black frame to fine-tune the tone.

Finally, save your settings on the left.

All done.
