iDSP INSTALL GUIDE
If you have two subwoofers in your system, you can use an RCA male to dual RCA female cable (also known as an ‘aux
splitter’) or other types of “Y” cables on the output of the iDSP to hook up both of your subwoofers. You could even use a
typical RCA male to stereo RCA cable, and use the white RCA plug for one subwoofer, and the red RCA plug for the other
subwoofer.
AV Receiver and Subwoofer Amplifier Settings
To avoid conflicts between the iDSP’s settings and your AVR / subwoofer amplifier settings, make sure to make the
following adjustments on both before using your iDSP. If your AVR or sub amp supports these settings, you will be able to
find how to adjust them in that product’s user manual/guide.
1) Adjust the low pass dial to the highest frequency available on your AV receiver and subwoofer amp to prevent
interference between your amp crossover and the iWoofer crossover. It is recommended to use the iWoofer software
crossover as opposed to the crossover in your subwoofer amp.
a. Note: A low pass filter means that all of the frequencies below this value will pass through, and frequencies above this
value will be attenuated and then altogether eliminated. This filter is essential for subwoofers and is one of the main things
that separates a subwoofer amplifier from a normal amplifier.
2) Turn off any EQ settings your amplifier, or AVR, might have for bass, to prevent interference between these settings
and the iWoofer software. EQ settings on an amp or AVR will prevent you from getting optimal results from the iWoofer
Pro’s room correction algorithm.
3) Turn off any additional processing you can find within your subwoofer amplifier or AVR unless you are confident it will
not conflict with any DSP settings in iWoofer.
4) Note about AVR Crossovers: For many AV receivers, there will be a single ‘crossover’ frequency setting that will high
pass your main speakers at this frequency, and low pass the signal going to the ‘sub out’ on your AVR. If this is the case
for your system, you will want to utilize this crossover, and set the low-pass frequency within the iWoofer app to 500
Hz (all the way up). It is important to high pass your main speakers with this crossover whenever possible to prevent
interference in the bass range between your main speakers and your subwoofer. Although it’s possible to get a good
response without high passing your mains, the iWoofer room correction algorithm cannot account for the bass response
of your main speakers, which is why we recommend high passing them.
iWoofer App Quick Start
Note: All screenshots shown are from the iOS version of the app. These
instructions will work for the Android app as well, but the look of the app is different.
1. Navigate to the app store of your smart device and search for the “iWoofer” or
“iWoofer Pro” app by Artem Khlyupin and install it.
2. As long as your iDSP has power and the Bluetooth of your smart device is turned
on, you will see a seemingly random string of letters and numbers when opening
the app (this can be renamed in the options menu of the app). Select this device, or
if you don’t yet have a iDSP, press demo mode to view the app. If you have multiple
iDSP devices, they will all show up here.
Troubleshooting: The device will enter standby after a while if it does not sense
any input signal and will not show up on this screen. If this happens to you, either
unplug your device and plug it back in, or provide an input signal to kick it out of
standby. If this does not work, make sure no other smart device is connected to the
iDSPwith the iWoofer app. Otherwise, try a different smartphone or tablet.
