Introduction
Congratulations on purchasing uandksound's products! Welcome to join the growing uandksound
owner family.uandksound's T-series studio-specific monitors are high-precision speakers that
continuously improve the processing of difficult audio. This is also the meaning of these monitor
speakers. They can really restore the sound in the sound material.
The key features and design elements of the T-series monitors make uandksound a "studio
standard." The series uses a very strict design concept, which is very similar to uandksound's
other uandksound products.

The T-Series includes new custom bass and tweeters, side-slanted side panels for improved
acoustic reflection and acoustic short-circuiting, and a new cabinet design that improves
structural integrity and provides an extended bottom end. The slotted sound hole can be greatly
eliminated. Less voice hole. In addition, we offer valuable features and practical features, such as
improved speaker protection circuitry to give users more peace of mind, using new drivers to
expand the frequency response.
The result is this trusted studio-specific reference monitor that delivers clear bass, clear
mid-range, and precise natural treble.
It's a subtle difference in key sound synthesis or the need to capture some special sounds, and
you'll immediately see that the T-series, like yourself, knows the job.
This manual will help you familiarize yourself with the many features of the D-series monitors and
how they operate. We hope that you will spend a few minutes familiar with this manual. Thank
you for choosing uandksound!
Important note: The T-Series monitors were originally packaged in specially designed carton.
Please keep these packaging materials in a safe place to transport or transport monitor speakers.
design concept
The monitor sound system in the studio is a tool that “measures”the sound channel changes in
an auditory manner. Ask an experienced sound engineer who thinks the best studio-specific
monitor speakers should be, basically you will get the same answer. That is "high precision, high
transparency, flat response and true restoration of sound."
Simply put, the electrical signals that the sound engineer wants to enter the monitor can be
reproduced by the mechanical action of the frequency converter, and the quality of the sound
that is desired to be reproduced is not biased or degraded to any degree. Professional sound
engineers rely on monitor speakers to express their sound as different audio media as accurately
as possible to convey their acoustic vision. Technically, this is achieved by a monitor that meets
three key important criteria. Spectrum balance, distortion management and resonance
management.
1. Spectrum balance (sound quality)
Studies have confirmed that the correct spectral balance is very important for studio-specific
monitor speakers.
Frequency balance is defined as
Smooth on-axis response
Smooth octave response

Smooth off-axis response
After years of audition and listening to feedback from top engineers and manufacturers,
uandksound engineers have mastered how to make properly tuned monitors an effective
recording tool.
The T-Series is designed to be as flat as possible to ensure that the sound you hear is the true
sound of the sound material without any rendering or enhancement. You can be confident that
the mix will be precise and phase-consistent.
2. Distortion management
Any loss or addition to the tone signal is distortion, which is present in the speaker itself. The
T-Series has extremely low speaker distortion, which clearly helps to provide a more accurate
sound reproduction.
Different power amplifier distortions, the most common such as intermodulation distortion,
transient love intermodulation distortion and harmonic distortion have also been eliminated.
The effects of physical conditions on the waveform, such as the intimacy and diffraction of the
sound holes, can also cause distortion. The design philosophy adopted by uandksound engineers
is based on the complete elimination of these lossy sound conditions or the minimization of their
impact.
3. Resonance management
Resonance means that after removing the drive source, some objects will tend to vibrate at a
particular frequency point. Resonance also has a crucial impact on the performance of the
speaker. The design element of uandksound is to minimize the resonance of the small drive and
the outer casing.
Design element
New custom tweeters and woofer designs - uandksound has a reputation for designing
high-performance studio-specific monitor speakers. T-series monitors are no exception. We have
specially customized a Kevlar fiber low frequency drive for each module. Kevlar is one of the
strongest, thinnest and hardest materials available for modern speaker cone structures. Kevlar's
special physical properties minimize the possibility of axial and conical fractures of the cone
structure. Both the tweeter and the woofer have a faster attack time. The new tweeter expands
the range and improves distortion.
Anti-Resonance Low-Frequency Expansion Enclosure Design The T-Series monitor enclosures are
made of MDF material, which has a stronger structural integrity than a cabinet made of standard
ABS solid materials. The method makes the strength of the box large, and the MDF also has a
resonance suppression characteristic, which can effectively extinguish the small box resonance.

The new cabinet design offers many benefits - the T-series monitors are manufactured in MDF,
depending on the basic design of the cabinet. The cabinet has an inner and outer partition wall
filled with a lightweight sound absorbing material. Advantages of MDF materials: One advantage
is that the cabinet design can be made with thicker partition walls. The sound absorbing material
located between the inner and outer hard shells serves as a sound insulating material to reduce
the possibility of resonance dry interference. The second advantage is that there are no parallel
partitions inside the cabinet. It is possible to eliminate standing waves and standing wave nodes
that are unfavourable to the internal and external acoustic response of the casing. All of these
features help to eliminate possible interference from the cabinet to the sound of the speaker
system.
The active sub-filter-T series amplifier contains three active filters. (Subsonic, low pass and high
pass). These three filters work together to achieve a seamless integration of the drive
components, ensuring smooth spectral balance.
Bi-amp design - uandksound's amplifier consists of high-fidelity components and a simple and
thorough audio path. The output power is balanced to match the sensitivity of the low frequency
and sorghum drives as well as power management. The T-series monitors use a toroidal
transformer for minimal noise.
Contoured panels - Like other uandksound speaker products, all cabinet zooms and sound holes
are rigorously shaped to reduce diffraction for better detail and stereo sound. The curved panel
reduces off-axis scattering and helps achieve better off-axis audio.
The slotted sound hole and the slotted sound hole reduce the intimacy and diffraction that are
common in poorly designed circular sound holes.
The limit switch can be disabled. The monitor has a limit circuit that provides more powerful
protection. This limit switch is off by default. The limit switch is used to reduce side effects
caused by the power amplifier and or the speaker drive overload. Enabling the limit switch will
greatly reduce the possibility of damage to the small drive. The limit switch can be turned off via
the “Limit Limiting Limit Switch”on the rear panel. It is limited to the use of the monitor
speakers within a reasonable range. The best level of no-audio distortion is determined by the
help of the indicators on the front bezel.

(A) System level adjustment
The input sensitivity is adjusted by an adjustment device that is neatly attached to the rear panel
(counterclockwise to reduce sensitivity). The adjustment range is from Min to Max. The preset
gain is Min, which is sufficient for most situations. Adjustments are usually required only when
the user is using a T-series monitor in a surround sound system and needs to balance the level, or
if the monitor's source is overheated and cannot be adjusted.
(B) High frequency adjustment (T6 only)
The high frequency adjustment is achieved by a 3-position toggle switch located on the rear
panel. The adjustment factor is +1dB, flat, or 1dB, and the upper limit of the high frequency is
2KH. “The commercial preset is flat (the toggle switch is in the middle). The type of adjustment
that should be taken is determined based on the room acoustics to ensure that the monitor has
the proper frequency response.

(B) Low frequency adjustment (T6 only)
This three-speed switch is used to adjust the low frequency response of the monitor. Poor low
frequency components are produced near the wall. Adjust the low frequency adjustment switch
to compensate for the over-amplified low frequency response. The type of adjustment that
should be taken is determined based on room acoustics to ensure that the monitor has the
proper frequency response.
When the monitor speakers are affected by indoor obstacles such as walls and corners, the low
frequency response can be adjusted by the three-speed pull switch. The “all”setting means
“whole space”and provides the strongest low frequency response. The "quarter" setting
means a quarter of the space, providing attenuated low frequency response. The “two-for-one”
setting means “half space”, and its frequency direction should be between no attenuation and
one-quarter space attenuation. The monitor speakers are preset by the manufacturer as “all”
space. More about this setting Please continue to read this document.
(C) Stroke indication limit switch
The limit indicator/limit switch has three set gear positions.
1. The “ON”position indicates that the limit indicator (red) is on and the limit switch is
bypassed. When the red indicator light is on, the amplifier output approaches the limiter value.
The red indicator light flashes occasionally to indicate that the monitor speakers are not damaged.
If the red indicator light is on for a long time, turn down the monitor input signal amplitude to
avoid damage to the speaker. When tracking the over-mixed volume, you can use the appropriate
setting of the limiter indicator to indicate that the monitor may be damaged due to excessive
volume.
2. The “OFF”gear position indicates that the limiter indicator (red) is newly opened and the
current limit switch is bypassed.
3. The "Limited" gear position indicates that the input signal will flow through the limiting circuit
and the signal will be limited when the signal amplitude exceeds a preset threshold. The indicator
light is illuminated when the amplifier is overloaded so that the limit switch is activated. The
duration and luminous intensity of the green indicator light will increase as the limit is increased.
Restriction devices are not recommended for mixing because the limitations on the audio signal
change their audio characteristics. If you do need to use a limiting device when mixing, it is
recommended to turn down the system input amplitude to prevent the audio signal from being
overloaded.

Connection system
Turn on the power
All connections are completed, all controllers and adjustments should be set to a minimum, and
all other equipment should be powered up before the T6 monitor is energized. The power on/off
switch is located on the rear panel.
Audio mute switch
When the switch is placed in the "on" position, the timing circuit will be activated. If the system
does not detect the audio signal, the high voltage power supply will be turned off after about 20
minutes. The low voltage power supply still supplies current. The monitor speakers will unmute
when the signal is detected. If the level of the audio material used is low or the sound is
intermittent, such as game music or surround mix, it is recommended to turn off the auto mute
switch.
Connector
The Neutrik®Combo connector plugs
into the XLR, 1/4" TRS and 1/4" earphone plugs.
Please note that the 2-pin input forward signal
must be connected to the sleeve at the signal
source if an unbalanced connection is used.
This can be done with a suitable wire or adapter.
Install monitor speakers
By definition, near-field reference monitor speakers reduce indoor reverberation. This contrasts
with conventional stereo configurations or large-scale speaker arrays during the recording period.
In the latter two environments, the sound from the speakers passes through the ceiling, walls
and floors, greatly enhancing the sound. Near-field monitors provide great flexibility due to the
reduced sound-to-ear path, making the sound less susceptible to different room environments.
Equally important is the ability to adjust high frequency and low frequency characteristics. It
compensates for the effects of indoor irregular environments and achieves high precision sound.
See the High Frequency Adjustment and Low Frequency Adjustment section of this manual. Note
that these adjustments are only available for T6.
A depressing indoor environment usually requires an increase in high response. Similarly,lowering
the high frequency direction can change the indoor reverberation. The first reflection of the
woofer can be compensated by adjusting the low frequency, whether it is a reflection from the
floor in a common stereo setting or a reflection from a mixing console (when the monitor is
placed on the tuning table bridge).
Placing the monitor near the back wall, side wall or corner enhances the low frequency effect. In
general, if you move the monitor to two or three feet from the wall or corner, the low frequency
