The WTX-1100 is a Bluetooth receiver designed to bring modern connectivity to any audio system. It supports aptX HD technology with transmission up to 24 bits/48 kHz. It uses a tri-core processor paired with a Cirrus Logic CS4344 converter to ensure high audio signal quality.
Robust Design and Versatile Connectivity
The Advance Paris WTX-1100 Bluetooth receiver is built around a sturdy aluminum casing. This metal construction sets the WTX-1100 apart from its predecessor, the WTX-700, while offering better protection for the internal electronic components. Its compact dimensions (130 mm wide, 150 mm deep, and 47 mm high) allow for discreet integration into any hi-fi environment.
The front panel features a glossy black acrylic finish, highlighted by three blue LEDs indicating operating status and transmission mode. A power button completes this sleek façade. The rear panel houses all the connections: a stereo analog output on gold-plated RCA jacks, a digital optical TOSLINK output, and a gold-plated coaxial RCA digital output. This triple connection option allows the WTX-1100 to adapt to virtually any existing audio system.
An adjustable Bluetooth antenna is attached at the back, ensuring optimal reception within a 10-meter range. Power is supplied via a micro-USB port, with an included power adapter featuring multiple plugs for different international electrical standards.
Technical Architecture and Signal Processing
At the heart of the WTX-1100 is a Qualcomm Bluetooth 5.0 chip (QCC solution), supporting SBC, AAC, aptX, and aptX HD codecs. This broad compatibility ensures optimal connection with all source devices, whether Android smartphones, Apple devices, or computers.
This high-level performance is made possible by the integration of a Tri-core processor, combining a 32-bit Dual-Core and a 120MHz Single-Core. This specific processing architecture efficiently manages the digital data stream, reducing jitter and optimizing audio signal synchronization.
The Cirrus Logic CS4344 digital-to-analog converter is another key component of the architecture. This 24-bit/192 kHz DAC incorporates several proprietary technologies, including PopGuard, which eliminates unwanted noise when powering on or off. The CS4344 offers a dynamic range of 105 dB, allowing both the most delicate passages and the most intense crescendos to be reproduced without compression or audible distortion.
The entire circuit benefits from meticulous design, with carefully selected components and optimized routing to minimize interference. The digital outputs allow users to bypass the internal DAC if they prefer to use an external converter of their choice.
Evolution in the Advance Paris Range
The WTX-1100 represents the culmination of a line of Bluetooth receivers that began with the WTX-500. The dongle format, which plugged directly into the back of the amplifier, has been replaced here by an elegant rectangular metal case, offering more space for circuitry and better heat dissipation.
Compared to the WTX-1000, its direct predecessor, the WTX-1100 brings several substantial improvements. The most notable is the addition of the aptX HD codec, allowing transmission up to 24 bits/48 kHz versus 16 bits/44.1 kHz for standard aptX. The tri-core processor replaces the previous architecture, offering greater processing power for real-time audio signal handling.
The Advance Paris WTX-1100 wireless audio receiver pushes the boundaries set by its smaller sibling, the WTX-700, by offering more comprehensive connectivity (including digital outputs), a Cirrus Logic CS4344 DAC, and a high-quality metal chassis. This evolution is accompanied by a noticeable improvement in the signal-to-noise ratio, further reducing the background noise inherent in any Bluetooth transmission.
Installation and Everyday Use
Setting up the WTX-1100 is particularly straightforward. After connecting it to the amplifier or audio system via one of the available outputs and powering it through the micro-USB port, the device is turned on with a press of the front button. On first use, the WTX-1100 automatically enters pairing mode, appearing as “WTX-1100” in the list of available Bluetooth devices.
Once the initial pairing is complete, the receiver remembers up to eight different devices, making future connections easier. Switching from one source to another happens automatically, with the last active device taking priority. This intelligent connection management eliminates tedious manual switching when changing sources.
The effective range reaches 10 meters in open space, with good tolerance to obstacles. Practical tests show a stable connection even through one wall, with the first dropouts only occurring beyond that distance. The adjustable antenna allows you to optimize reception according to the room’s layout.
