Introduction
We greatly appreciate your purchase and trust that your new SX-1000R will provide you top-notch performance and years
of satisfaction. All Wyred 4 Sound products are designed with one thing in mind: to bring the beauty of your music to life. Our
hope is that you will come to admire us as a true audiophile-centric company committed to producing award-winning
products that offer real value and pride-of-ownership.
Design Features
The SX-1000R is a perfect example of what can be accomplished when excellent engineering, knowledge and execution are
combined. Adding to that are the high-caliber components used, selected for their functionality, durability, and quality.
Benefitting from its own dedicated power supply, the SX-1000R will produce peaks in excess of 625W with 8Ω loads and
1225W with 4Ω loads. 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.
A note on the input stage
With a meticulous and refined input stage that has been optimized for frequency response, distortion and performance,
balanced or unbalanced inputs can be utilized with exceptional results. A tremendous amount of time has been spent tuning
the front end to help produce a sound that is at once fluid, dynamic and involving. The circuit includes a dual-differential
common mode converter which has been derived from our award-winning DAC-2. Regardless of input type, the high-quality
differential input stage allows us to feed the amplifier with a true balanced signal. Another function of the front end is to
isolate impedance mismatches which would otherwise become harmful to the sound. The high 91k Ω input impedance
ensures synergistic matching with both solid state and tube components without loading down the output stage of your
source. Furthermore, our third generation technology will significantly reduce the detrimental effects of a noisy source
through balanced circuitry, audio grade capacitors, and the quad-paralleled front end.

Getting Connected
⚠
CAUTION: Disconnect the power cord or power the unit off before making any connections to reduce risk of electric
shock and/or loudspeaker damage. NOTE: This is a true balanced amplifier. Never connect outputs to a ground point. Doing
so may cause damage to the amplifier and/or connected gear and also void the warranty.
1. Power Switch
Use the rocker switch to power the amp on or off. Although leaving the amplifier always on should be ok, we
recommend turning equipment off when not in use, especially for long periods of inactivity. Powering the amp off
will also help protect against electrical surges and spikes.
2. Outputs
The WBT nextgen™ binding posts are some of the finest available. Use high quality speaker wire terminated as bare
wire or with bananas or spades.
3. Inputs
Either XLR or RCA interconnects may be used. For optimal performance, we recommend XLR.
4. AC Inlet
Attach the supplied or your own power cable here. Be sure to observe proper voltage. Use of a quality surge
protector is recommended to help prevent any damage from potential electrical events.

5. 12v Trigger In
You can connect the 12v trigger output of your preamp or source to the 12v trigger input of the SX-1000R for easy,
remote power up. When the unit is in standby via the remote trigger, the amplifier is on, but disabled. The current
draw in standby mode is less than 5W per channel. The trigger input will work from 5-15v, so there should be no
issues with voltage tolerance on source outputs rated for 12v.
6. XLR/RCA Switch
The XLR/RCA switch completely isolates the XLR input from the RCA input. This eliminates any possible combination
of signals should both inputs be connected simultaneously. Be sure to set the switch according to the type of
connection you are using.
Placement
The SX-1000R is built to provide years of trouble-free enjoyment. To maximize its life and your enjoyment, be sure to treat it
like you would any fine piece of quality equipment. Take care not to place it in areas where excessive dust, dirt, moisture or
other contaminants are present. A minimum of 4” of clearance should be observed around the top and sides to allow for
airflow. We recommend elevating it on an audio rack, shelf or amp stand instead of placing it directly on the floor.
Light Bar Brightness
The light bar brightness can be adjusted through a hole on the bottom of the chassis. Dim or brighten the light bar by using a
miniature flat head screwdriver and rotating the potentiometer inside. In this way, the light bar can be turned completely off if
desired.
Short Circuit/Over-Current Protection
Your SX-1000R has built-in current and thermal protection. Before any damage can be done by short circuit, over-current or
temperature, the amplifier will go into protect mode. If this happens, the output is immediately terminated. Should this occur,
power the amplifier off prior to troubleshooting. If the amplifier is abnormally warm/hot, let it cool before powering it back
on. If the amplifier is not beyond excessively warm, check all connections for possible shorts. If you can’t find any indication
of the problem, disconnect everything but the power cord and power it on. If the unit powers on but no sound is heard when
you connect it back to your system, the unit may need to be repaired. Contact your dealer or Wyred 4 Sound if this occurs.
“Break In” Period
Your new SX-1000R series amplifier will deliver outstanding performance right out of the box. However, optimal
performance will be realized after it reaches normal operating temperature. Further improvements will be heard once all of
the internal components have had a chance to “break in”. Experience has shown that the amplifier will realize its full potential
after being played ~300 hours.

Troubleshooting
No Sound?
If you have your source and speakers connected with music playing but no sound is audible, check the following:
1. Ensure none of your components are in ‘mute’
2. Verify that the power cord is plugged in and that the both the unit and outlet are powered on.
3. Check the front panel and make sure that the light bar is on.
4. If the light bar is o 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
5. 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.
6. Verify that the XLR/RCA switch is properly set.
7. Try replacing the interconnects to verify the connection between the amplifier and source is sound.
8. Verify your interconnects are working by replacing them on a different set from a connection that you know works.
9. 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?
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 troubleshooting purposes only, 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 start disconnecting components one at a time, starting with your source
component. Digital cable boxes and satellite receivers are notorious for creating a 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
If the SX-1000R faults, see section “Short Circuit/Over-Current Protection” above for possible reasons. 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, it may mean you may need a more powerful amplifier for your tastes or system. If it faults without playing too loud,
your speakers may be too demanding and may require a higher wattage amplifier. Contact your dealer or Wyred 4 Sound for
further assistance.
