THX® Ultra2™ Certified
THX certification, it is your guarantee that it will accurately present movies the way they were mixed by the filmmaker in the studio. In the case of THX Ultra2 certification - the ultimate benchmark for home audio performance—a power amplifier must offer high-quality, high-output performance for multi-channel playback in large rooms. Among the strict criteria that THX uses for judging the quality of a power amplifier are measurements of continuous power output, distortion levels, and heat generation.
All-Analog Circuitry Unaffected by Digital Noise
A standard integrated A/V receiver has the dual task of both processing and amplifying audio signals, and is therefore susceptible to noise interference from digital circuitry. As a dedicated power amp with all-analog circuitry, the DTA-70.1 suffers no such interference. When partnered with a high-quality pre-pro, the DTA-70.1 offers all the benefits of pure analog amplification: a warm, musical, and full-bodied sound.
HICC (High Instantaneous-Current Capability) - Experience audio with greater dynamics
When an amplifier outputs an audio signal, the connected speakers accumulate energy, reflex, and send energy back to the amplifier. The amplifier must then immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current required to achieve this is also necessary to handle speaker impedance fluctuations, which can force an amplifier to provide four to six times its usual current load. The DTA-70.1’s instantaneous current capability ensures that audio output is not affected by power limitations. In order to handle high levels of instantaneous current, the DTA-70.1 incorporates several key design features.
