The Arylic B50 is a versatile Bluetooth stereo amplifier designed to enhance your audio experience by offering both wireless and wired connectivity options, along with the ability to transmit audio to other Bluetooth devices. This device serves as a central hub for various audio sources, allowing you to connect traditional analog and digital components, as well as modern digital media.
At its core, the B50 functions as a stereo amplifier, capable of driving passive speakers with a robust output. It integrates Bluetooth 5.2 technology, enabling it to act as both a Bluetooth receiver (RX) and a Bluetooth transmitter (TX). As a receiver, it allows you to stream music wirelessly from your mobile phone, tablet, or other Bluetooth-enabled devices to your connected passive speakers. As a transmitter, it can take audio from any of its input sources (Line in, Phono in, Optical in, HDMI ARC, USB disk drive, or USB DAC) and stream it wirelessly to up to two Bluetooth speakers or earbuds simultaneously. This dual functionality makes the B50 a flexible solution for various listening scenarios, from powering a traditional stereo setup to wirelessly extending audio to other rooms or personal headphones.
The B50 offers a comprehensive array of input options to accommodate a wide range of audio sources. It includes a dedicated Phono input with a ground connector, specifically designed for turntables, providing the necessary amplification for vinyl playback. A Line input (RCA) is available for connecting devices with line-level outputs, such as CD players, tape decks, or other analog audio equipment. For digital audio sources, the B50 features an Optical input, supporting high-resolution audio up to 192kHz/24bit PCM encoding, and an HDMI ARC (Audio Return Channel) port, allowing seamless integration with modern televisions to enhance TV audio through your passive speakers. Additionally, the device is equipped with a USB Type-A port for playing music directly from USB disk drives and a USB Type-C port for connecting to a PC, enabling it to function as an external USB DAC (Digital-to-Analog Converter).
Output options are equally comprehensive, including banana plug terminals for connecting 4-8ohm passive speakers and an RCA subwoofer output for integrating an active subwoofer into your audio system, providing enhanced bass response.
The B50 is designed for ease of use, offering multiple control methods. The front panel features a power switch, an IR sensor for remote control, and a multi-functional volume knob that also serves as an input mode selector. A series of status LEDs clearly indicate the current input source and Bluetooth status. For instance, a flashing Bluetooth LED signifies receiver mode awaiting connection, while a steady Bluetooth LED indicates a successful connection. When in transmitter mode, the Bluetooth LED will flash alongside the active input source LED.
The included remote controller provides convenient access to all essential functions, including power on/off, volume adjustment, input source selection (Phono in, Line in, Optical in, ARC, USB, DAC), play/pause controls, and dedicated buttons for enabling Bluetooth transmitter pairing and receiver mode. It also offers treble and bass control, as well as preset EQ options (Flat, Classic, Pop, Jazz, Rock, Vocal) to tailor the sound to your preferences.
For advanced control and customization, the B50 integrates with the "Go Connect" mobile application, available for both Android and iOS devices. This user-friendly app automatically detects nearby B50 devices and allows for comprehensive control over playback, input source selection, Bluetooth pairing, Bluetooth transmission, and in-depth EQ settings. This provides a modern and intuitive way to manage your audio system.
Connecting to Bluetooth devices is straightforward. In Bluetooth receiver mode, the device appears as "B50 XXXX" (where XXXX is the serial number) on your transmitting device. Once connected, the B50 remembers paired devices for automatic reconnection. The B50 supports connecting up to two Bluetooth devices simultaneously in receiver mode, allowing for seamless switching between audio sources. In Bluetooth transmitter mode, the B50 will search for nearby Bluetooth receiver devices (speakers, headphones) and connect to them, streaming audio from the selected input source. The device also supports connecting a second Bluetooth receiver device, expanding your wireless audio distribution capabilities.
The USB disk drive playback feature offers resume playback, meaning if you stop playing music, switch input modes, or unplug the drive, the B50 will resume from the last played song when you re-enter USB mode. This adds a layer of convenience for users with extensive local music libraries.
The B50 is designed for reliable operation. In the event of an issue, the status LEDs will flash if the device enters protection mode, typically due to overheating or a short-circuited output. In such cases, the user is advised to turn off the device and check for the cause.
For troubleshooting or resetting the device to its default settings, a reset button is located on the back panel. This button serves multiple functions:
Firmware updates are indicated by all LEDs turning on, and users are instructed not to power off the device during this process to ensure proper update completion.
For advanced audio tuning and customization, the B50 is compatible with the "ACPWrokBench" Windows application (sold separately). This software allows users to fine-tune audio effects such as Music Noise Suppressor, Virtual Bass, Stereo Widener, Exciter, and a 10-band EQ. The application provides real-time feedback during tuning, and custom settings can be saved and exported for use with other B50 devices, offering a high level of personalization for audiophiles.
The device's design, with external antennas for both BLE and standard Bluetooth connections, ensures optimal wireless performance. The use of a dedicated power adapter provided with the package is emphasized to prevent damage to the device, highlighting a key aspect of proper maintenance and longevity.
