A preamp, also known as a preamplifier, is an electronic audio amplifier that converts a weak electrical audio signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and an active speaker. Without this, the final audio signal would be noisy or distorted. Can be used with Arylic active speakers, such as RK525.
The preamp is to amplify the audio signal to the input range acceptable to the power amp. It has the characteristics of selecting the required audio source signal and amplifying it to the rated level and beautifying the sound.
The role of the preamp:
Select the required audio source signal and send it to the rear stage, and at the same time close other audio source channels, and amplify the audio source signal to the rated level to achieve high-fidelity sound quality.
The difference between an audio power amplifier and a preamplifier
The preamp is to amplify the audio signal to the input range that the power amplifier can accept, and the audio power amplifier is to generate the maximum power output to drive a certain load amplifier under the specified distortion rate conditions.
The preamp is an audio processing device before the input audio power amplifier; the amp controls the power of the sound, and the preamplifier controls the audio range.
Arylic s50 preamp has a built-in high-quality DAC, which can improve the sound quality. Support Ethernet RJ45, RCA and AirPlay, DLNA, UPnP, Spotify connect, Qplay input, RCA and Optical output. It can turn your traditional old-fashioned wired active speakers into wireless speakers and improve the sound quality.

Love it! Great customer support!
This is my first streamer which I connected to active speakers and television via optical. I must say, the real potential of my speakers im using now. Best quality dac in the price range and steamer is the must have thing for audiophile for wireless music. This will go with me for long.
Ich bin voll zufrieden mit dem Gerät, einziger Kritikpunkt ist die 4Stream App, die hängt sich gerne mal auf und muss neu gestartet werden.
Really great product.
I have 30y old Denon amplifier, which now step into digitized world!
I use this as preamp to watch TV (out to powered speakers and sub). Small and easy to use, as well as easy to crank music from phone via bluetooth. Love that 1/8” stereo out from TV is governed by TV volume, so that I can still just use 1 remote! Could have used optical, but then need extra remote for volume.
I own the S10, A50 and S50. They are all working very well. Very happy with them.
