TEAC will release the AI-301DA-Z pre-main amplifier with USB-DAC, which is said to be ideal for high-quality playback of TVs and notebook PCs, from January 29th. The price is open, but it is expected to be sold at around 52,800 yen including tax. Equipped with a Burr-Brown DAC "PCM1795", it supports up to PCM 192kHz/32bit high-resolution sound source playback and DSD 11.2MHz native playback. When connected to the TV via optical/coaxial digital, the power can be turned on and off in conjunction with the TV, and the "remote control learning function" allows you to adjust the volume of this unit with the remote control of the TV or recorder, so you can connect the speaker here. If you connect it, you can enjoy high-quality sound playback on your TV. The power amplifier is made by Denmark's ICEpower, and adopts the HCOM (Hybrid feedback Controlled Oscillating Modulator) method that faithfully amplifies the input signal and the MECC (Multivariable Enhanced Cascade Control) feedback loop. With a high output of 40W + 40W (4Ω) and a highly efficient circuit design, it generates little heat and does not require a cooling fan, providing a quiet environment required for pure music listening. In addition, the headphone circuit uses the CCLC (Coupling Capacitor Less Circuit) method. High-dimensional headphone listening with sufficient low frequency and good response by eliminating the adverse effects on sound caused by capacitors in general headphone circuits, such as phase delay, low-frequency level reduction, and capacitor-colored sound. It is said that the environment will be realized. The input terminals are equipped with RCA x 2, USB-B x 1, optical digital x 1, coaxial digital x 1. The USB connection supports "asynchronous mode" that eliminates transmission jitter and "Bulk Pet" transmission technology that allows you to enjoy changes in sound quality with four types of transfer modes. In addition, it also supports Bluetooth connection. In addition to SBC/AAC, the codec supports aptX, and a newly received codec confirmation function is also installed. Frequency response is 2Hz - 100kHz (-5dB), S/N is 95dB (LINE input, IHF-A/LPF 20kHz 1kHz 2V input), THD+N is 0.01% (1kHz, 8Ω, 1W). The housing is designed with a compact size of 215mm width based on the concept of "compact high-performance audio that can be placed on the desktop". Adopting an aluminum panel, a motor-driven volume knob, and a robust metal chassis with excellent damping properties, it maintains the dignity of an orthodox Hi-Fi device while minimizing the impact of vibration on sound quality. matter. Equipped with screw type (banana plug, AWG8 compatible) speaker terminal, subwoofer output (RCA pin jack), and headphone output. The external dimensions are 215W x 61H x 254Dmm (including protrusions) and the weight is 2.1kg. It comes in two colors, black/silver.
