The ST series amplifiers are a stereo amplifier design that will produce peaks in excess of
125W/330W/625W with 8 ohm loads and 220W/625W/1225W with 4 ohm loads per channel depending on
model. Each channel of the stereo amplifiers is powered from their own dedicated power supply. The compact
and effective design is made easy thanks to the switching power supply that powers the bridged switching output
stage derived from ICEpower™ technology.
In comparison with other products similarly provided by many companies, our product is superior. The
ST series amplifiers contain input stage which we designed to act as a buffer between your amplifier and your
input source. Our proprietary FET input stage couples your gear directly to produce an input impedance of
60.4K ohms which makes the integration of preamplifier selection endless. Other companies connect the input
and output connectors directly to the amplifier module which will not properly mate with select preamp sources
because of the low input impedance, and will cause less than optimal sound.

As you can see, the front panel doesn’t offer any sort of power switch or function buttons. The window
that is located in the middle of the front panel will appear to be blue when it’s is in operation mode. There is also
a potentiometer that can be accessed from the bottom of the unit to control the brightness of the light bar. A
small screwdriver like what is used on sunglasses must be used to adjust the brightness. Slowly adjust the turn-pot
until the desired brightness is achieved.

When power is applied to the amplifier and the switch located on the rear is in the on position, the
amplifier 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 ST series amplifiers make absolutely zero noise internally and to connected gear and shouldn’t be in
any way noticeable of its operation other than the blue light bar 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.

The ST series stereo amplifiers are equipped with a 12VDC remote trigger. You can connect the 12V
trigger output of your preamp or source to the 12V trigger input on the amplifier for an easy remote power up
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 5W 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.

The light bar can be adjusted for brightness through a clearance hole on the bottom of the chassis. As a
factory standard, the amplifiers are configured for maximum brightness. One can dim the light bar by using a
miniature flat head screwdriver (sunglass repair driver), and rotating the potentiometer on the bottom of the
chassis. The light bar to be turned completely off if so desired by rotating the potentiometer in the opposite
direction as delivered. Also having multiple amplifiers may require the units to be adjusted for common
brightness between units.

CAUTION: Disconnect the power cord or put the power switch in the off position before making
any connections to your amplifier to minimize the risk of electric shock and possible loudspeaker
damage. Power your amplifier 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.
The binding posts that you will find on the ST 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 preamplifier.
Using the new W4S power and interconnect cables would be a great way to ensure your system is
closer to what we call “our reference”. We are now offering superior cables at an affordable rate that
anyone can afford. For more information, please visit the web-site, or send an email to
support@wyred4sound.com.

One of the benefits of the ST series amplifiers is the input stage. The proprietary dual, fully balanced
FET input stage offers unparalleled integration with any source. The input stage helps your preamp drive your
amplifier with ease. What happens with our competitors units is that the input signal becomes hard to drive at
times, and some sources start to clip at that point. The signal that causes the most “stress” (peaks) is what will end
up being chopped up, or incomplete. The input stage will provide a constant 60.4k ohm load on the source.

The XLR/RCA switch on the rear of the unit completely isolates the unbalanced input from the balanced
input. The separation of all connections is to eliminate any possible combination of signals if both happen to be
connected simultaneously. The input to the amplifier can only be selected by either the XLR or RCA input at
any given time.

Each channel of the amplifier has its own over-current and thermal protection. Before any damage is
done by a short circuit, over-current, or over temperature, the amplifier will go into protect mode. When this
happens the output is immediately turned off and the music will turn silent. The best procedure to take, should
something like this happen is to turn the amplifier off immediately. Determine what has caused the problem. If
the amplifier is beyond operating temperature, give it a chance to cool, and then power it back up. If the amplifier
is not beyond normal operating temperature, check all connections for possible shorts. If you can’t find any
reason for the problem, disconnect everything from the unit and power it up. If the unit powers up, but no sound
is passing through when you connect it your system, your unit may need to be repaired.

Your new ST 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. One will find that the initial 100hours, 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 one 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.
Leaving the amplifier on all the time is recommended for optimal sound and will not shorten its life, nor will it
degrade future sound.

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 switch is selecting the proper input for what you have connected.
6. If the switch is in the proper position and still no sound, then try replacing the interconnects to verify
the connection between the amplifier and source.
7. Verifiy 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.

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 preamplifier 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
trouble shooting 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.

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. If it faults
without playing to loud, your speakers may be too demanding for what you have and may require a higher wattage
amplifier. Contact your dealer or Wyred 4 Sound for other options you can explore.
