Introduction
Our product goal is simple: to deliver the beauty and realism of your music into your home with as little change as
possible. We know what our competition has to offer, and you can be sure that we constantly strive to make the
value of our products substantially more. We hope you enjoy your new Wyred 4 Sound product for years to come,
and that you consider us in the future as we continue to provide exceptional and innovative audio components to
music lovers worldwide. All Wyred 4 Sound products are proudly designed and hand-assembled in California.
Design Features
There are many reasons why the STI-v2 series integrated amplifiers are better than the competition. To start with, the
volume control in the STI-v2 is a true-resistive ladder type that offers truer linearity and superior sonic quality. The
line-stage within the integrated doubles as an unbalanced to balanced converter which provides a balanced signal
from unbalanced inputs.
A loop in/out feature is also on hand with the STI-v2 integrated amplifiers. In the setup menu, you can select the loop
feature to insert a digital crossover or similar devices into the audio path. When the loop feature is activated, Input 5
becomes loop in, and the AUX out becomes loop out.
With a set of balanced inputs, 4 sets of unbalanced inputs and a set of unbalanced outputs, connection possibilities
are vast. Absolute phase and balance control are easily managed via the included full-function remote.
User interface is made easy with the VFD display and optical rotary encoder. Allowing input naming and HT Bypass
input selection, the setup menu is easily accessed for customization. Several display dimming steps including “off”
are available through the remote. Powering up the STI-v2 can be done by pushing in on the volume knob, by
pressing power on the remote, and by the remote DC trigger in when HT Bypass is selecting in the setup menu.
When an input is selected to be used as the HT input, the DC trigger can be activated by a surround processor to
power up the unit, and automatically set the volume to unity gain. This allows for all volume controls to be made
through the surround processor. When the processor is shut down, so is the STI-v2. When 2-ch listening is desired,
then manual operation can be executed from the front of the unit, or through the remote.
Front Panel Operation
The front of the STI-v2 offers several features, power on/off, input selection, volume control, muting, setup routine,
and display for user feedback. For phase, balance, and dim control, the remote must be used. To enter the setup
mode, input up and down must be pressed simultaneously with pushing in the volume knob. Once in the setup
menu, input up/down is used to scroll through the settings, mute is used to select the setting for adjustment, and the
volume knob is used to adjust the setting. For input naming, the volume control is used to select the character and
the mute button to move to the next character position for adjustment. Once all settings are made (they are
automatically saved once changed), the setup menu can be closed by pressing and holding the power button
(volume knob) at any time.

Setup Menu / Instructions
To enter the setup menu proceed with the following steps:
1. Make sure the unit is plugged in, power switch on rear is on, and the unit is off.
2. Push and hold in the Input up and down buttons while pressing the power button (knob) once.
3. Release all the buttons when the setup screen shows up on the display.
4. Use the input up and down buttons to navigate the menu function.
5. Use the mute button to select and enter the menu function.
6. Use the volume knob to change the setting with-in the menu function.
(You can press the input buttons to save the settings and move to another function)
7. Once all settings have been made, press the power button again (knob) to set and store your selections.
When selecting the HT Bypass input, make sure that the proper input is selected which is connected to your HT
processor. When the trigger is applied after this setting is made, the unit will automatically select that input, set the
volume to -0db, and turn on other connected equipment via the DC trigger output.
When the Loop out feature is used, Aux out becomes the loop out which will feed the connected components input,
and Input 5 will become the loop in which will come from the output of the connected component. Please note: the
loop in connectors are directly connected to the internal amplifiers as if the unit was a standalone amp with 27db of
gain. The loop out is controlled by the volume control, but the loop in is not. Make sure you have all connections
made properly to ensure no damage is made to your equipment.
Powering Your STI-v2
When power is applied to the STI-v2 and the switch located on the rear is in the on position, the STI-v2 will turn on.
If you would like to manually turn the amplifier on and off, this switch is where you would want to do so. Leaving
your amplifier on all the time will not hurt it, shorten the lifespan, or degrade the future sound. The STI-v2 series
amplifiers make zero noise internally and to connected gear. The unit shouldn’t be in any way noticeable of its
operation other than the display status on the front panel. To prevent power surges, we recommend using quality
surge suppressor equipment. Turning the switch off on the rear of the unit will also protect against surges and spikes
should some occur without proper protection.
DC Trigger
The STI-v2 series stereo amplifiers are equipped with a 12VDC remote trigger input and output. You can connect the
12V trigger output of your processor or source to the 12V trigger input on the amplifier for an easy remote power up
and HT configuration every time. When the unit is in standby via the remote trigger, the amplifier is powered up, but
disabled. The current draw in standby mode is less than 10W per channel, and shouldn’t measure too much on your
electricity bill. The trigger input will work from 5-25V, so there shouldn’t be any issue with the voltage tolerance on
source equipments outputs rated for 12V. You can also connect the trigger output to additional amplifiers or
equipment to be turned on and off with the STI-v2 amplifier.

Getting Connected
⚠
CAUTION: Disconnect the power cord or power the unit off with the back switch before making any connections
to minimize the risk of electric shock and possible loudspeaker damage. Power your amplifier on after all final
connections have been made. NOTE: This is a balanced amplifier and you should NEVER connect either output to a
ground point! Doing so may cause damage to your amplifier and/or connected gear and void warranty repair.
The binding posts that you will find on the STI-v2 series are made of nothing but the best. Each binding post is made
of highly ductile “OFC” copper alloy. Both clamping nuts are built out of one piece, and offers excellent grip. All
metallic surfaces offer a 24-carat gold-plating, and are non magnetic surfaces. The binding post will accept 4mm
banana plugs, spades of 6 and 8mm, and crimped cable ends up to 10 AWG. The easiest connection is made with
banana plugs, but be sure that you use the highest quality that you can find. Make sure that the banana plugs fit
snugly into the terminals. Some inexpensive banana plugs can cause a highly resistive connection which can result in
a noticeably higher distortion output to the connected speakers.
The RCA (unbalanced) jack is made with high quality gold plated copper, and should be properly connected with
interconnects of the same value. The Neutrik XLR (balanced) connectors are the finest balanced connector on the
market, and are the best possible option for connecting your amplifier to your sources.
Using Wyred 4 Sound power and interconnect cables would be a great way to ensure your system is closer to what
we call “our reference”. We offer superior cables at an affordable price. For more information, please visit our website
or send an email to [email protected] .
“Break-in” Period
Your new STI-v2 series amplifier will deliver outstanding performance right out of the box. However, you should plan
on improvements as it reaches its normal operating temperature and once all of the components have a chance to
“settle in”. Our experience has shown that the amplifier has reached its’ potential after the initial 300 hours. You will
find that the initial 100 hours, the amplifier will start to shed the initial “brightness” and somewhat harsh transitions.
During the second 100 hours, the amplifier will start to become more fluid, and smoother overall. The remaining 100
hours is where the lesser of the change happens, and you might still notice improvements over time.
After the initial break in period, your amplifier will be ready to perform within minutes of powering it on.
Troubleshooting
No sound? If you have your input source and speakers connected and you can’t get music to play, check the
following:
1. Verify that the power cord is plugged in and that the outlet is powered up.
2. Check the front panel and make sure that the blue light is on.
3. If the front panel is blue and there still isn’t any sound, put your ear next to the tweeter of your speaker and have
someone turn your amplifier off then on again at the rear switch. You should barely hear a click when the amplifier is
turned on and off
4. If you can hear the amplifier turn on and off, but there still isn’t any sound, make sure you are getting a signal to it.

5. Verify that the input selector is selecting the proper input for what you have connected.
6. If the input is in the proper position and still no sound, then try replacing the interconnects to verify the connection
between the amplifier and source.
7. Verify that the interconnects are conducting by replacing them on a different set from a connection that you know
works.
8. Now that you have interconnects that you know work, try connecting the amplifier to another source that you
know has worked in the past.
If you are still experiencing problems after checking all possibilities and using the resources provided please contact
your dealer or Wyred 4 Sound directly for further assistance.
Got Hum?
Is there too much hum or hiss coming out of your speakers? If you put your ear right next to the tweeter of your
speaker, you should barely be able to hear any hiss from the amplifier in normal conditions. If the noise is easily
heard at a distance, try putting your source on mute, or pause. If this eliminates the noise, it’s inherent in the source
or preamplifier. If your source doesn’t disconnect the outputs when muted, and the noise still exists while muted, try
disconnecting the inputs to the amplifier. If the noise is still there when the inputs are disconnected, and the inputs
are shorted with shorting plugs, then your amplifier may need some servicing. If the noise is not there when the
inputs are disconnected, try putting a cheater plug (ground isolator) on one or all components in order to eliminate a
ground loop issue. NOTE: We only recommend using a ground isolator for troubleshooting purposes, and should be
removed after the problem has been found. Having the ground of any unit disconnected can potentially create a
dangerous situation.
An easy way to locate a noisy component is to replicate the problem then start disconnecting components one at a
time, starting with a source. Digital cable boxes and satellite receivers are notorious for making ground loop hum.
This is normally caused by the potential difference on the input wire (shield side) for either of the boxes when
referenced to ground. If this is the case in your system, the installation of an isolating transformer would be the
easiest solution and are normally readily available at your local electronics parts store. A better solution is a power
strip with grounded and surge protected F-connectors that you can pass a signal through.
Amplifier Faults
When the amplifier faults, there will be no indication other than the lack of music. The STI-v2 series amplifiers are
very robust and can handle the heaviest of loads. Under normal circumstances, there shouldn’t be any issues with
faulting. If you suspect a problem, check the outputs and speaker connections to make sure they aren’t shorted to
each other or ground. If the amplifier faults while playing music loud, you may need a bigger amplifier for your taste
or system. Contact your dealer or Wyred 4 Sound for other options you can explore.
