5. Tips and Troubleshooting
A. DSPB Tips and Troubleshooting
1. Noise
a. If a DSPB is connected to an ICP1, and that ICP1 is plugged into a computer, sometimes
noise can be picked up from the
computer’s USB port. If this occurs, try a different USB
port and make sure to unplug your ICP1 from the PC when it is not in use.
b. If using a laptop, try disconnecting it from power if possible.
c. Turn the amp gain down and turn the input volume up. With the gain all of the way up,
it is expected to have more noise than with it at a lower gain.
d. Check to make sure there is not any damage to cables or ports.
2. The DSPB worked fine before powering it off, but powering it back on there is no sound.
a. This can happen if an ICP1 is connected to a PC, and that ICP1 is connected to a DSPB,
but the DSPB and PC are turned off. When both get turned back on, you might get no
audio.
b. The fix is simple, just unhook your ICP1 from the DSPB and plug it back in if desired.
Press the reset button on the DSPB if sound still does not come on when removing the
ICP1.
3. In general, pressing the reset button on the products in the DSPB series can help solve problems
a. Power cycling can help, as an alternative.
4. My DSPB doesn’t sound like a normal amplifier, something sounds wrong.
a. Try adjusting the potentiometers corresponding to the high pass filters on the board.
b. If using a stereo board, make sure to carefully follow the wiring diagram to ensure your
speakers are in phase with each other. Wiring speakers out of phase will make them
sound incorrect.
5. Follow the guides above closely.
B. ICP1 Sigma Studio Troubleshooting
1. Many problems, especially connection problems, can be solved with a reboot of your Windows
PC and then following the connection guide steps exactly from the start.
2. I cannot get my ICP1 to program.
a. Follow the ICP1 Sigma Studio Connection guide under the quick start section of this
guide. It is not enough to just make the correct connections, it is required to do the
steps in order to have consistent connection results.
b. It is important to try a different micro USB cable . Many micro USB cables endure a lot
of abuse from charging devices, and although they might still provide power, they might
have issues transferring data.
Some micro USB cables don’t have the connections
necessary for data connection to begin with, and were manufactured strictly for power.
These cables are often included with devices that strictly use a micro USB port for
power, and are not intended to be controlled with a PC.
3. I have my potentiometers set correctly in my SigmaStudio schematic, but they don’t work.
a. Ensure that the register control menu is set correctly to utilize the potentiometers. See
the section “ ICP1 Sigma Studio Connection - Quick Start ”
