TREVOCE EQ DSP SUBWOOFER INSTALL GUIDE
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 an ‘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 Pro-
App (IOS only)and simply use your phones 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 auto-
room 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 “+” icon, to delete select “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.

Name: By default the Name field 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 defaults 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 app to import preset from DSP, this one is the manufacturer’s default preset.
Change Pairing Code: let you to set a password to you subwoofer/app. In case if 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 allow you to save/load and export presets. Please note that only after saving a preset the subwoofer will
memorize a new parameters. Without saving a preset, subwoofer loses a new parameters after turn Off. Export presets
carried out thru the IOS email account, but the import could work by hyperlink on website.

HW Controllers (not recommended)
Hardware controller options lets you to adjust or deactivate up to four knobs or switches on the rear panel of your
subwoofer. For a full control by app please switch off all controllers, otherwise turning Off/On of the subwoofer will return
the control to the rear panel knobs.
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, signal is less/more than Auto On Threshold, or input
clipped).
SHS
The ability to retore 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.
