TREVOCE15 EQ DSP SUBWOOFER INSTALL GUIDE
Installation Precautions:
Before installing
Thank you for buying the latest version of our most popular subwoofer.
The additional upgrades we have made make this the best all-round sub in our history. Incorporated in the Trevoce15 EQ DSP is the
new native EQ, and the IWoofer DSP engine. The native EQ has allowed us to extract the maximum bass extension possible from our
design. This allows the full range of musical instruments and special effects to be reproduced. The Trevoce EQ DSP Series does this all
without any increase in the size of the sub. Our Trevoce subs offer the smallest footprint you will nd in triple driver designs.
Before connecting your subwoofer, make sure all equipment is switched off and that voltage switch is set to your country’s voltage. Do
not connect the subwoofer power supply cable before completing all connections.
Features:
World Class Digital Amplier Technology
The TreVoce DSP Series powered subwoofer incorporates the latest digital amplier technology to maximize performance

solutions available.
Tuned System Performance
Rear mounted volume control, low pass crossover, phase control and App controlled DSP ensure optimal system integra-
tion and built-in native EQ ensures the deepest bass frequencies.
Cabinet
An attractive furniture quality solid cabinet with ‘leather’ nish, provides the foundation for high sound quality and clarity.

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
connections changing may be heard. Use the standard ON mode only if needed, 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:
1. 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.

2. Set the controls and switches to their initial setup positions:
VOLUME set the dial to 50% or 12 o’clock
CROSSOVER adjust the upper frequency limit. The purpose is to control the overlap the upper frequencies of the
subwoofer and the main speakers lower frequencies. Check your main speakers specs to determine their low-end
limit.
PHASE set to 0°
3. 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.
4. Continue listening to your favorite source track and experiment with the phase control until you nd 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.
5. Initial setup is now complete.
Trevoce 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 iWoofer App (IOS Only) that adds additional functions available for a small
fee.
iWoofer Setup
1. If you intend to use the custom DSP functions you must rst download the iWoofer app from the App Store or Google Play.
2. Continue reading to setup iWoofer app to access and setup the custom DSP features of the TreVoce.

X-Over Menu
From here you will be able to ne-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 ltering, or sealed
acoustic suspension speakers needing 12dB per octave ltering, we have you covered. The innitely 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 reections. 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 lters 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.

Options Menu
Name: By default the Name eld lled 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 rst 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.

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 lter F 10:10000Hz. Sometimes needed to match the phase of the main speakers in the cross-over
region.
