Reftone 2LD 監聽喇叭及DTA-120迷你擴音機套裝

Reftone 2LD are small, passive near-field reference speakers that allow you to hear full range audio clearly at low volumes, for accuracy and placement. The clarity in the midrange exposes sonic details that may be hidden on some active monitors. In a mix, there are so many important things in the midrange so it’s crucial to hear every element clearly. Because they accurately represent the midrange and low-end so well, Reftones help you make audio decisions that don’t need to be corrected later. Use Reftone to check your sound for all stages of production: tracking, editing, mixing, mastering, broadcast and post-production (ADR, foley, sound design, video/audio editing). They are made for all user levels and environments like professional and home studios, laptop rigs, edit bays, DJ booths and mobile recording/editing setups. Engineers, Producers, Broadcast Pros, Video Editors, DJs and Students all trust Reftone speakers when they make their crucial audio mix decisions. Designed by an audio engineer, the proprietary paper driver and high quality wooden cabinetry make Reftone the reference speakers your ears can rely on too.

Big-Amplifier Power

The DTA-120 amplifier delivers the power of a monster amplifier in a tiny package. Thanks to Tripath’s proprietary Class T technology, plus a robust Dual Parallel BTL configuration, the DTA-120 tackles the toughest speaker loads with ease, all while delivering the sound quality and low distortion of a conventional Class-AB amplifier. The dual-power-chip design delivers 60 watts (RMS) per channel of efficient power into an 4-ohm load (up to 120 watts total), and 40 watts (RMS) into 8 ohms – continuously, with no reduction in output. That means powerful bass and clear output that keeps on going, even with the most demanding speakers.

Convenient, Small Size

With the DTA-120 amplifier, you get the most power possible from the smallest footprint imaginable. At under 3-1/2” wide, 2-1/4” tall, and 6” deep, the DTA-120 delivers more power per cubic inch than any other mini amplifier. All this is thanks to the revolutionary, cool-running Class T digital PWM amplifier technology and the extruded aluminum heatsink case. The robust external switching power supply hides out of sight. But since it can supply high current with even higher peaks, the DTA-120 can easily drive HUGE speakers.

High-End Features and Quality

The DTA-120 amplifier delivers the features you expect in a much more expensive amplifier, at a fraction of the size and price. The housing is black-anodized aluminum, with a thick machined faceplate and a silky-smooth volume control. The rear panel features high-quality, gold-plated RCA inputs and shielded, gold-plated 5-way binding posts that accept any type of speaker cable. A high-current DC power jack is also used to ensure maximum power transfer to the amp. On the front panel, there’s a second 3.5mm audio input jack, as well as a ¼” headphone jack that receives its signal from a separate, high-quality headphone amplifier stage controlled by the main volume knob. (3.5mm to ¼” adapter included.)

Works With ALL Your Sources

In a world of changing digital and wireless specifications, the high-quality analog design of the DTA-120 remains virtually future-proof. Just connect it to any device with a headphone output jack and begin enjoying powerful, high-quality audio through your own speakers. Short signal paths inside the amplifier preserve all the quality of the input signal, and the DTA-120 automatically switches from the rear inputs to the front input when connected. No switches to flip, and just one knob. The DTA-120 is the perfect complement to your smartphone, tablet, laptop, PC, television, or any other audio source.

Head-Fi Friendly Design

The DTA-120 is the ultimate desktop amplifier. Not only can it drive even the smallest and least-efficient speakers to almost painful levels without strain, making it perfect for powering desktop mini-monitor speakers, but it also offers a separate solid-state headphone amplifier stage capable of powering even the most demanding headphones to high listening levels while preserving clarity, detail, and a refined sonic character. However you like to listen at your desk, the DTA-120 is the perfect partner.
