Premiera D1S: High-End Class D Integrated Amplifier

Premiera D1S is a modern integrated Hi-Fi stereo amplifier of class D with a built-in network player, DAC, Bluetooth, HDMI ARC, Wi-Fi, AirPlay 2 and a nominal output power of 101 W per channel (4 Ohm) with distortion less than 0.08%. The appearance of the Premiera D1S amplifier, despite its compactness and restraint of design, is extremely functional – on the front panel there are only two encoders (control knob and volume control), a display and a headphone jack. The display is very informative, and a convenient and simple settings menu, which can be controlled using the encoder or remote control, allows you to select the desired source for playback, turn on loudness compensation, adjust the tone block, adjust the display brightness and, if necessary, return to factory settings.

The Premiera D1S has seven different inputs for all kinds of input signal sources. The HDMI ARC input expands the capabilities of the preamplifier, allowing you to play the soundtrack from any modern TV that supports this function. You can connect two analog sources to the D1S’s stereo RCA inputs. The adjustable line output allows you to use the D1S as a preamplifier. The digital signal is processed by the modern ES9018K2M Sabre DAC with 32-bit HyperStream™ architecture. The convenient and intuitive Audio System mobile application allows you to connect to Wi-Fi and configure the amplifier’s network player.

The Premiera D1S output stages operate in class D, which uses pulse-width modulation (PWM). PWM technology provides the compact amplifier with high efficiency (about 90 percent), exceptional frequency response linearity when reproducing a wide frequency range, and low distortion. Premiera D1S is a modern compact integrated amplifier with an original design, a wide range of functions, the latest analog and digital technologies, universal use, excellent sound, and a price that is unlikely to be offered by its closest competitors.
