Overview
The Dayton Audio DSP-LF, when combined with the iWoofer app, allows for Bluetooth controls of all of
the popular DSP functions you can expect to find in a subwoofer DSP.
There are two versions of the iWoofer app. The free version that is available on both Android and iOS
has the following features.
- Adjustable frequency
and slope high/low
pass filters (up to 48
db/oct)
- Parametric EQ (up to
25 bands)
- Gain Control
- Subharmonic
Synthesis
- Delay Control
- Phase Control
- Limiter / Compressor
- Dynamic Bass
The premium version of the app (iWoofer Pro, $5) is only available on iOS. The main difference between
these apps is the addition of a room correction feature that utilizes the microphone of your iPhone or
iPad and corrects the room response of your subwoofer with advanced algorithms that automatically
create FIR filters tailored to your specific room and subwoofer. The premium version of the app is only
available on iOS because all iOS devices use consistent microphones with a smooth, predictable
frequency response that can be compensated for in software. Android microphones are not as
predictable as an iOS microphone , due to the number of manufacturers and different implementations.
The premium version of iWoofer also adds extra settings for the limiter/compressor and dynamic bass
control.
Device Connection and Setup
Power
Because of its minimal current draw and convenient 5V micro USB power connection, the DSP-LF can be
powered by nearly any USB Type-A port with a standard micro USB cable. You could use the supplied
power brick, a TV USB port, a desktop or laptop port, or even the port found on the Dayton Audio BSA-
200 or other subwoofer amplifiers to power the DSP-LF. Since Dayton Audio cannot verify the integrity
of all power sources, if results are not satisfactory, it is recommended to use the supplied USB power
brick.
Input Audio Signal
Connecting the DSP-LF to a typical AV receiver is easy. Simply use the provided RCA to 3.5 mm cable by
plugging the RCA end into the 'sub out' port on your AV Receiver (AVR) and the 3.5mm end into the
input side of your DSP-LF. It is okay only to use either the red or white RCA plug, and leave the other
one unused, but you can also use an RCA Y Adapter that is 2 Female to 1 Male to eliminate this.
