TA-10.1 Class-T Stereo Audio Amplifier

Trends TA-10 Class-T Stereo Audio Amplifier

Trends Audio introduces the mini-size Class-T stereo amplifier TA-10 providing up to 2x15W output with the bundled AC power supply unit. Thanks to the Tripath's proprietary Class-T Digital Power Processing (TM) technology and our special techniques in circuit design and component selection, TA-10 achieves the sound quality of high-end HiFi but in a very affordable price. TA-10 performs very like Class-AB amplifiers with high fidelity and warm sound. Yet, its power efficiency and physical size is just like Class-D amplifiers. Even it's maximum output power is only 2x15W, TA-10 is actually powerful to push even the floor-stand speakers with sufficient and good control of bass sound.

Audiophile amplifier is no longer "The Larger, the Heavier & the Hotter, the Best Sound"!!! This is a revolution technology among these several eras of the audio techniques. Though the product is only in a palm size, the sound quality is audiophile grade. Yet, the price is only one tenth of the same quality amplifiers. It is totally broken the tale story that “the larger, the heavier, the more power consumption, the hotter, the best sound amplifier”. We shoot down the audiophile amplifier in the high sky. Let more audiophiles, music lovers or even PC/Mac users can enjoy the high fidelity music in an affordable price.

Audio techniques are at a standstill The Hi-Fi user should know that though the CD, SACD, DVD-Video, DVD-Audio, EVD, HDV, Blue-Ray DVD, etc… audio video storage and replay technologies are ever-changing, the basic amplifier technology has no change for 60 years. The most popular Class-A, Class-AB, and Class-B amplifiers are several eras’ technology. Only the production technologies of electronic components and accessories improved. The basic technology and sound quality has no revolution improved. The later developed Class-D amplification technology though has the advantages of mini-size, energy saving and low heat; the sound is not very good. It can only apply for the low-end audio composites, Television, active multi-media speakers. It’s difficult to reach the field of audiophile. That’s why “the larger, the heavier, the more power consumption and the hotter, the best audiophile amplifier” is becoming a truth by most audiophiles in these eras. Recently, even more audiophiles go back to play tube amplifiers.

Class-T amplification broken the bottleneck Trends Audio’s TA-10 applied the well accept Tripath’s proprietary class-T audio amplification technology. This integrated the class-D digital audio signal processing technique (PWM) with the Class-AB power amplification into a small IC. It has the mini size, low heat advantages of Class-D amplifiers and also has the high fidelity sound quality of Class-AB amplifiers.

Ingenuity Design + Audiophile Materials Besides applied Tripath’s class-T technology, Trends TA-10 also put much effort and applied much proprietary techniques into the circuit design, components matching, sound tuning and even the case grounding and shielding. Additionally, we applied audiophile electronic components, wholly aluminum case (light, stylish, good shielding from interference), standard gold-plated sockets, high-quality AC power supply. All of them significantly improve the sound performance.

For circuit & function design, there are much more thoughtful functions for audiophiles:

1. Separated amp unit & power supply: It reduces the mutual interference and also let audiophiles freely to match different power supplies as they want. The 12V lead-acid rechargeable battery should be a good alternative (battery provides purer DC than electric network).
2. Separated analog ground and digital/power ground to reduce interference. The proper decoupling and shielding by the case further reduce interference. The purer sound and silent background achieved.
3. Added the DC Offset tuning circuit (Left-bottom side of the picture) to effectively reduce the DC between the speaker terminals down to 1mV. It further improves the signal noise ratio.
4. Simply reset the jumper to (Left side of the picture) skip the volume knob and related circuit to change the amplifier as pure power amplifier. You can then add a tube or transistor pre-amplifier before to increase the driving power and to tune the sound.

• applied the proprietary T-amp technology for audiophile quality sound, high power efficiency (90%) and less heat generation
• compact design (mini-size & light weight), easy portable and setup
• provide up to 2x15W output
• an AC adaptor is bundled for continuous power supply.
• separated amplifier & AC adaptor design to minimize mutual interference and flexible to apply other power sources, e.g. lead-acid battery.
• standard gold-plated audio and speaker sockets used to be compatible with most audiophile quality cables.
• applied the specially designed audiophile-grade “Trends” MKP capacitors as audio input coupling capacitor which guarantee the best original audio signal feed into the amplifier. [Trends TA-10.2 Series only]
• applied the lowest LSR & highest ripple current Rubycon MCZ series tank capacitors as the power filtering capacitor which best suit the switching PWM characteristic of class T (class-D) amplifier. [Trends TA-10.2 Series only]
• applied the smaller yet better quality ALPS 9mm sealed volume pot which provide better sound in the volume control
• applied 4mm thick aluminum faceplate .
• provided the option of TA-10.2P (Power Amplifier edition) which cancelled the volume pot and simplified the front panel for those who always apply it with Trends PA-10 or other pre-amplifier for audio selection & volume control.
• Re-organized the sockets layout of the back panel which provides a more convenient audio cable and speaker cable connections. [Trends TA-10.2 Series only]
• enhanced the chassis with beautiful satin finish and smarter black/white contrast. [Trends TA-10.2 Series only]
• the DC bias between speaker terminals can be offset (close to ±0mV) by adjusting the potentiometers (factory pre-set). It suppresses the "pop" sound when power on/off and also increase the sound purity.
• option to work as a pure power amp by simply reset jumpers to by-pass the volume controlling circuit
• built-in over-current protection
• built-in over-temperation protection
• audiophile-graded parts and components
• 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.
