Please take note the following instructions before installing your Trends TS-10/
TS-10R Hi-Fi System, they will enable you to get the best performance and prolong
the life of the product.
- This unit must not be exposed to dripping or splashing water or other liquids. No
objects filled with liquid, such as vases, shall be placed on the unit. In the event,
switch off immediately, disconnect from the main supply and contact your dealer or
us for advice.
- Do not route the power cable so that it can be walked upon or damaged by other
items near it.
- Electronic audio components have a running in period of around a week (if used
several hours per day). This will allow the new components to settle down; the
sonic properties will improve over this time
- If you do not intend to use this unit for a long period of time, unplug it from main
socket.
- To clean the unit, wipe its case with a moist, lint-free cloth. Do not use any cleaning
fluids containing alcohol, ammonia or abrasives. Do not spray an aerosol at or near
Trends TS-10/TS-10R Hi-Fi System.
- These units are not user serviceable, never attempt to repair, disassemble or
reconstruct the unit if there seems to be a problem. A serious electric shock could
result if this precautionary measure is ignored. In the event of a problem or failure,
please contact your dealer or us.

Thank you for purchasing Trends TS-10/TS-10R Hi-Fi System. This package
provides a set of amplifier unit and loudspeakers. The amplifier unit, Trends TA-10.2
SE, applies the latest proprietary T-amp technique enabling it to provide audio quality
for audiophile with high power efficiency (up to 90% lesser) and low heat generation.
Despite of the hand-held size, its output is equivalent to gigantic high-end products,
while it costs only 1/5 to 1/10 of the latter. With the provided Trends SA-10/SA-10R
Speakers, Trends TS-10/TS-10R Hi-Fi System is absolutely the best choice of
audiophiles longing for quality, cozy and simplicity.

4.1 Trends TA-10.2 SE Mini Class-T Stereo Amplifier
·applied the proprietary T-amp technology for audiophile quality sound, high power
efficiency (90%) and less heat generation.
·provide up to 2x15W output for area 200-300 ft2 (20-30m2).
·an AC adaptor of low ripple and noise is bundled for continuous power supply
(without changing batteries).
·minimized mutual interference by separation between amplifier & AC adaptor.
Flexibility of applying other power sources, e.g. lead-acid battery, is reserved.
·applied the audiophile-grade Trends MKP capacitors as audio input coupling
capacitor which guarantee the best original audio signal feed into the amplifier.
·applied the latest Rubycon MCZ series tank capacitors, the best companion of
Trends Tripath Class-T amplification, as the power filtering capacitor.
·applied ALPS volume knob.
·option to work as a pure power amp by simply reset jumpers to by-pass the volume
controlling circuit.
·standard gold-plated audio and speaker sockets used to be compatible with most
audiophile quality cables.
·built-in over-current protection.
·built-in over-temperature protection.
·applied 2-sided high quality PCB.
·DC bias is adjustable up to ±5mV (pre-set before shipping), allowing to suppress
the "pop" sound when power on/off and also increase the sound purity.
·air-core inductor used (instead of magnetic-core) for better sound.
·the stylish & specially-plated aluminium case provides not only good-looking, and
also provides outstanding shielding capability.
4.2 Trends SA-10/SA-10R Speakers
·1" polymer dome tweeter with neodymium magnet and lightweight for low mass
and clear, detailed highs.
·tweeter is aligned left and right respectively for better 3-dimensional effect. (Trends
SA-10R only)
·Double Magnet structure for shielding and optimized field strength, lowering
distortion from vibration.
·applied the proprietary Trends core inductor for better sound.
·low loss rubber driver surrounds for a lifetime of reliable high performance.
·sockets is plated with 24K gold making better audio performance.
·compact design, easy setup for Hi-Fi room, living room, sleeping room or even
right beside your laptop computer.

6.1 Offset the DC bias voltage of the speaker terminals
There are two blue adjustable potentiometers (Rt) for offsetting the DC bias voltage
between the positive (+ve) and negative (-ve) terminals of each channel. Offset this
DC bias voltage can enhance the purity of the sound and minimize the “pop” sound
when power on and off. The DC bias has been pre-set in factory. But after run-in for a
period, it would be slightly changed that the fine-tuning is needed.
Before you tune these, you need a screwdriver (take off the case), a small
screwdriver (turn the screw of the potentiometer) and a (digital) multi-meter to
detect the DC bias voltage.
1. Use screwdriver to take out the two top level screws in the front panel & another
two screws in the back panel. Then, open the upper case.
2. Power ON the amplifier.
3. Use the multi-meter to detect the DC voltage (200mV) between +ve & -ve
terminals of the RIGHT channel.
4. Turn the screw on the top of the LEFT (near the front panel) potentiometer by a
small screwdriver clockwise or anticlockwise until the voltage as close as to
±0mV.
5. Then, repeat step 3 and 4 for the LEFT channel by turning the screw on the top
of the RIGHT (near the back panel) potentiometer.
6. Power OFF the amplifier.
7. Cover back the upper case and tighten the screws.
6.2 Configure as power amplifier (by-pass the volume control)
You can simply configure the amplifier as an integrated amp (with volume control
function) or as a pure power amp (no volume control function) by resetting the
jumpers in J2 as follows:
