Fine-Sounding 60Wpc Rotel A12 Integrated Amplifier Handles Digital and Analog, Features Integrated aptX Bluetooth, Wolfson 24-Bit DAC, MM Phono Preamplifier, and More

Analog or digital. Streams or physical formats. Wireless or wired connections. A one-box solution engineered to handle practically any music need and reproduce it with addictive fidelity and faithfulness, the Rotel A12 integrated amplifier comes with aptX Bluetooth, a MM phono preamplifier, outstanding Wolfson 24-bit/192kHz DAC, and PC-USB input capable of DSD. And it’s all housed in a sleek, space-saving 3.625 x 17 x 13.5-inch (HWD) chassis. 

Functionally, the 17.6-pound A12 outputs a conservatively rated 60Wpc of continuous power. Four sets of line-level inputs, four digital inputs, a preamp output, a front-panel headphone input, two sets of speaker binding posts, and RS232 connectivity speak to its flexibility. Inside, a robust power supply anchored by a Rotel-manufactured toroidal transformer along with British-made slit-foil capacitors ensure A12 can handle difficult-to-drive speakers as well as challenging dynamic peaks. 

It all means that A12 presents your source – be it an LP, CD, file, or stream – with sought-after clarity, warmth, detail, and accuracy. Unlike most mass-market integrated amplifiers, it benefits from construction techniques that prize hand-selected parts and careful execution of circuitry and signal paths. Whether employed in a den, office, bedroom, or your main listening area, A12 punches far above its weight class and gives you a plethora of options as well as user-friendly operation that extends to tone controls, a 12V trigger, front-panel iOS input, and handy remote control.

"The Rotel A12 is one of the few amps we’ve reviewed with a PC-friendly USB input – and it does so for under $1,000. The amp’s delicious midrange and overall musicality are practically miraculous at this price. Bluetooth sweetens the deal, though if you want network audio features, you’ll have to look elsewhere or be willing to add an external gadget. But for those who want a fine cabled solution to most connectivity challenges, this little amp excels."
– Mark Fleischmann, Sound & Vision, Top Pick

"The Rotel A12 is an easy recommendation for anyone looking to move beyond mass-market stereo receivers. It delivers great sound for $999, with enough power to make it compatible with many speakers."
– Al Griffin, SoundStage! Access

"The A12 is the sort of amp you can build a first-rate audiophile system around, and not break the bank."
– Steve Guttenberg, CNET

Circuit Topology 
It’s not enough to simply use good parts. Where you put them is equally if not more important. Which is why Rotel keeps circuit paths as short as possible. That’s also why it often uses more expensive "onboard" relay source switching rather than routing a signal from a rear panel input to a front panel control. Rotel also relies heavily on Symmetrical Signal Trace design. This keeps each channel’s signal path identical to the others to preserve the imaging and soundstage. In addition, the company employs electrically superior "star" grounding techniques to improve performance because star grounding routes all ground connections to a single point to reduce potential loops that might introduce noise or produce hum. Further, Rotel Class A/B amplifiers don’t use output inductors because they decrease control and, consequently, sound quality.

In-House-Built Power Supplies
The heart of any audio component is the power supply, of which the type, size, and material plays a major part. Refusing to leave something so important to anyone else, Rotel invested the money and developed the knowledge to build its own toroidal transformers. Without a good power supply, the rest of the design can never deliver the desired performance. Rotel engineers carefully evaluate the power requirements of each new model. This information is conveyed to the transformer engineering team, which calculates the requirements including voltage, current, physical size, and product type. These engineers then design the exact specification for the transformers and begin the process of designing the transformer and winding a sample for testing. Each transformer is custom built to exacting standards using materials conforming to the strictest of standards. The metal winding material of the transformer is rigorously checked to confirm no impurities exist in the steel. The wire used for Rotel transformers is sourced from trusted suppliers that produce certified documentation of the copper materials. Each transformer core is built, baked, wound, and stress-tested to ensure power supply delivers all the clean, undistorted power each component requires for optimum audio performance.

Critical Evaluation
Rotel has found that critical listening is as important, if not more so, than even the most sophisticated instruments in the hands of experienced engineers. That’s why its development team places such importance on critical listening sessions. Electronic and acoustic engineers, both in the U.K. and Asia, have honed their aural acuity over the course of decades of collective experience to evaluate each stage of product development from working samples, through pre-production and, finally, to verify that final production is the same as the pre-production units. Some sessions evaluate different circuit elements: capacitors, resistors, and active devices such as transistors or operational amplifiers. Others focus on differences in circuit layouts or differences caused by power-supply elements.
