ROKSAN, network playback compatible integrated amplifier

Streaming Amplifier/Integrated Amplifier

The Streaming Amplifier/Integrated Amplifier is an integrated amplifier equipped with an amplifier circuit that has been improved while being based on the ROKSAN components. The difference between the two models is the presence or absence of Blue Sound's multi-room streaming platform "BluOS".

Both models have a power supply unit equipped with a powerful 400VA high-capacity toroidal transformer, a multi-layer board that realizes a short signal path, and minimize crosstalk between each input system in an amplifier with a mixture of digital and analog sources. Equipped with a ground-switching technology that suppresses the noise, it is designed to reproduce various sources with high sound quality.

Streaming Amplifier equipped with BluOS supports streaming services such as Amazon Music, Spotify, Deezer, TIDAL (not yet serviced in Japan), Qobuz (not yet serviced in Japan). It also has a network playback function, and supports PCM playback and MQA decoding up to 192kHz/24bit. It can be operated with the BluOS control app.

The Integrated Amplifier is not equipped with BluOS, but it has S/PDIF input, MM phono input, and Bluetooth input, and can be combined with CD Transport and Turntable to build a smart system. In addition, MQA decoding is not supported.

Both are compatible with Bluetooth, and the profile supports A2DP. Codec supports SBC, AAC, aptX.

The input terminals are equipped with RCA x 2 systems, MM phono/RCA x 1 system, coaxial x 2 systems, and optical digital (up to 96kHz/24bit) x 2 systems. The output is equipped with RCA x 1 system that also serves as a pre-out and a 3.5mm stereo mini terminal.

The Streaming Amplifier is also equipped with a LAN terminal and USB x 2 systems as digital inputs. It also has a USB-miniB terminal as a control terminal.

The power amplifier output is 80W+80W/8Ω, 130W+130W/4Ω. The SN ratio is >80dBa@1W/8Ω, >98dBa@75W/8Ω. THD+N is <0.02% (1kHz, 2ch, 1W@8Ω, A-weighted). Channel separation is >75dB@10kHz. Gain is 29dB.

The SN ratio of the preamplifier is >104dB (unweighted). THD+N is 0.002% (1kHz, 2Vrms, A weighted). Channel separation is >102dB (1kHz, 100mV).

Power consumption is up to 350W, less than 0.5W in standby. External dimensions are 432 x 373 x 76 mm (width x depth x height/including terminals). The weight is 10.48kg for the Streaming Amplifier and 10.37kg for the Integrated Amplifier. A remote control, a Wi-Fi antenna (USB), and a USB cable are included.
