Settings & Controls
Setting the Power Mode
ON Mode
If the subwoofer is set to ON mode, it will always be ready to play. However, undesired noise from interference or connection changes may be heard. Use the standard ON mode only if needed, and set the power switch to OFF when not in use.
AUTO Mode
Setting the switch to AUTO enables AUTO Sense. The subwoofer turns ON and OFF automatically in response to signal input. The subwoofer will enter standby mode if no signal is sensed for longer than 15 minutes.
Set the MODE switch to the ON position for setup.
After making all the connections, setup your subwoofer using the following steps
- Plug the subwoofer into an electrical outlet using the included power cord. The status LED will illuminate solid blue when power is present and the subwoofer is ON.
- Set the controls and switches to their initial setup positions
VOLUME set the dial to 50% or 12 o’clock
CROSSOVER adjusts the upper-frequency limit. The purpose is to control the overlap of the upper frequencies of the subwoofer and the main speakers’ lower frequencies. Check your main speaker’s specs to determine their low-end limit.
PHASE set to 0° - Play a movie scene or soundtrack and set the system volume to an average level. Listen to the bass level from your favorite listening position and adjust the volume accordingly.
- Continue listening to your favorite source track and experiment with the phase control until you find the best setting for you. Depending on the location of the subwoofer the bass may sound louder and deeper when the phase has been optimized. In some cases adjusting the phase will have no audible difference.
- The initial setup is now complete. Trevose Subwoofers are equipped with pre-programmed built-in EQ for optimal sound and great performance. You may also use the (optional) iWoofer app to access and custom-tune the DSP to suit listening preferences or room correction for example. There is also a Pro version of the woofer App (IOS Only) that adds additional functions available for a small fee.

iWoofer App: DSP Discovery & Connect
From your listening position, using the Android or Apple App iWoofer App you can make any adjustment needed to get the maximum out of your system.
Open the iWoofer App and Turn On Bluetooth to allow iWoofer to connect to accessories. You may tap Ok, and the app will go into Demo Mode. Otherwise, tap Settings, turn ON Bluetooth, next tap on the Home button, and open the woofer again. Bluetooth range is (30-65ft) the app will find any number of subwoofers equipped iWoofer Hardware, all of them will appear under “Devices Found:” Choose the UDID or MAC address that shows up for your iWoofer-equipped sub.
Main Menu
Ok, we have seen the UDID, and by tapping it we get the main control menu.
The app has a renaming function in the Options/Name menu, and the UDID number could be replaced for any name whatever you like.
X-Over Menu
From here you will be able to fine-tune your subwoofer, carefully matching the main speakers to the sub, using variable slopes and role-offs. Whether you have ported main speakers, needing 24 or even 48dB per octave filtering, or sealed acoustic suspension speakers needing 12dB per octave filtering, we have you covered. The infinitely variable phase correction and choice of cross-over points also provide for much better integration with the main speakers. X-Over – control of Low Pass and High Pass Filters (LPF/HPF), double tap (or tap & hold on > 1S) on the slope to select one, slide left/right to control a frequency (20:500Hz), and up/down to control a ‘Slope” order (2:4:8 or 12/24/48 dB/oct Butterworth). Use this to match your main speakers with the subwoofer.
The LPF/HPF frequencies limit the frequency range for Room Correction (Pro App only).
The Xover menu also controls up to 25 bands of fully Parametric Equalization
The built-in 25-band digital parametric equalization allows you to correct for frequency response dips and peaks caused by positioning and room reflections. You can do this by ear, or use a free frequency response app, or upgrade to the ProApp (IOS only)and simply use your phone’s microphone to measure the frequency response and then start making up to 25 different equalization adjustments until the response curve has been corrected. For iPhone users you can run autoroom equalization/correction, allowing the Pro App to create the EQ filters needed to deal with Room Acoustics issues.
Equalizer (PEQ), to add a new PEQ tap to the “+” icon, to delete select the “Trash” icon. Slide curve right/left to set a frequency, up/down to set a gain (db), zoom in/zoom out to control a Q factor (PEQ bandwidth), double tap (or tap&hold on > 1S) on PEQ line to select it.
Options Menu
Name
By default the Name field is filled with UDID, you may rename it there. UDID shows the MAC address of the connected iWoofer Hardware.
Restore Factory Setting
In case you want to reset all parameters to defaults. Be aware that this default is not exactly the same as was preset by the manufacturer of your subwoofer. As mentioned before, the very first connected iWoofer hardware will offer an app to import preset from DSP, this one is the manufacturer’s default preset.
Change Pairing Code
Let you set a password for your subwoofer/app. In case the password is forgotten, please press and hold the Pair button on the rear panel of your subwoofer during 3Sec. The subwoofer password will be reset to zero. Preset Manager allows you to save/load and export presets. Please note that only after saving a preset the subwoofer will memorize new parameters. Without saving a preset, the subwoofer loses new parameters after turning Off. Export presets are carried out thru the IOS email account, but the import could work by hyperlink on the website.
Preset Manager

Auto On/Off
Allows you to adjust auto On threshold in mVRMS units, and hold On time in minutes. 10mVRMS and 2 minutes are default values.
Gain Slider
The volume slider with Input Level indication (gray/green/red means, the signal is less/more than Auto On Threshold, or input clipped).
SHS
The ability to restore sub-harmonics that have lost or not been included in early recordings. All musical notes consist of the original note and a series of harmonics or fundamentals of that frequency, combined, they produce the note you hear. Sub Harmonic Synthesizing (SHS) restores those lost harmonics. Sub Harmonic Synthesizer (old tracks bass restoration, a good example is Jackson Sisters – I Believe In Miracles or Diana Krall – Temptation). Ideal for sealed subwoofers.
Delay Controls
2.5:65mS or 5:67.5mS for the FIR room correction mode (latency 2.5/5mS). Sometimes needed to match the delay with full-range speakers (if delayed).
Phase
The 1st order all-pass filter F 10:10000Hz. Sometimes needed to match the phase of the main speakers in the cross-over region. For Pro-App features and explanations download the full digital manual from osdaudio.com
