What Is the WTX-1100?
The Advance Paris WTX-1100 is a Bluetooth receiver for hi-fi systems. It lets you play music from your phone, tablet, or laptop on your home speakers — no wires between your device and the receiver.
Most Bluetooth receivers just focus on being easy. The WTX-1100 focuses on sound quality. It uses aptX HD, which sends music at 24-bit quality — the same as hi-res music files. Inside, a Cirrus Logic CS4344 DAC turns the digital signal into analog sound. A tri-core processor cleans up timing errors before the signal reaches the DAC. The result is better-sounding wireless music.
The WTX-1100 replaces the older WTX-1000. The new model adds aptX HD (the WTX-1000 only had standard aptX). It also has a better DAC and a sturdier aluminum case.
How It Gets the Most Out of Bluetooth
Bluetooth used to mean lower sound quality. Two things have changed that: better codecs and better processing. The WTX-1100 uses both.
aptX HD codec. Standard Bluetooth (SBC) strips a lot of detail from your music. aptX HD keeps much more. It streams at 24-bit/48kHz — the same bit depth used in hi-res downloads. The WTX-1100 also supports standard aptX (CD quality at 16-bit/44.1kHz), AAC (for iPhones), and SBC. So it works with every Bluetooth device.
Tri-core processor. Jitter means tiny timing errors in digital audio. Even small jitter can make music sound harsh or blurry. The WTX-1100 has a tri-core processor — a 32-bit dual-core plus a 120 MHz single-core. These fix the timing before audio reaches the DAC. This keeps your music clean and smooth.
Cirrus Logic CS4344 DAC. A DAC is the part that turns digital music into analog sound. Many Bluetooth receivers just use the basic DAC inside the Bluetooth chip. Advance Paris uses a separate one — the Cirrus Logic CS4344. It’s a 24-bit/192kHz converter picked for better sound. Using a dedicated DAC is a key reason the WTX-1100 sounds as good as it does.
Three output options. The WTX-1100 has three ways to connect to your system. Stereo RCA analog output for any amp with a line-level input. Optical Toslink digital output for feeding an external DAC. Coaxial RCA digital output for the same job using a coaxial cable. Having all three means it fits almost any setup.
Who Is This Best For?
You want to stream music from your phone to your hi-fi, and you care about how it sounds.
You have an Android phone with aptX HD and want a receiver that can use it.
You want to use your own DAC. The digital outputs let you send the signal to your preferred converter.
You own the older WTX-1000 and want a step up to aptX HD.
You want a Bluetooth receiver with a solid metal case — not a plastic dongle.
How Does It Connect to Your System?
The WTX-1100 has three outputs. You can use one, two, or all three at the same time.
Stereo RCA analog output (gold-plated) — the most common choice. Run a pair of RCA cables to any open input on your amp or preamp. This carries the analog signal after DAC conversion. Ready to play.
Optical Toslink digital output — sends digital audio to an external DAC. Use this if you have a better DAC you’d rather use.
Coaxial RCA digital output — does the same job as the optical output, but with a coaxial cable. Some gear works better with one type. Having both gives you options.
Pairing is simple. Turn on the WTX-1100 and put it in pairing mode. Find it in your phone’s Bluetooth list and tap to connect. The WTX-1100 remembers up to 8 paired devices. You don’t have to pair them again each time. Only one device plays at a time.
The unit comes with a power adapter and an external antenna for better Bluetooth range.

Features & Specifications
24-Bit Wireless Audio — aptX HD
The WTX-1100 streams at up to 24-bit/48kHz over Bluetooth using aptX HD. It also supports standard aptX, AAC (for iPhones), and SBC. Every Bluetooth device works with it.
Dedicated Cirrus Logic CS4344 DAC
Advance Paris uses a separate Cirrus Logic CS4344 DAC instead of the basic one in the Bluetooth chip. This 24-bit/192kHz converter was chosen for better sound quality. It does the job of turning digital music into the analog signal your amp needs.
Tri-Core Processor for Low Jitter
A 32-bit dual-core processor and a 120 MHz single-core processor manage audio timing. This keeps jitter — small timing errors that hurt sound quality — very low. Clean timing means cleaner sound from the DAC.
Three Output Options
One stereo RCA analog output (gold-plated), one optical Toslink digital output, and one coaxial RCA digital output. All three work at the same time. Use the analog output for your amp, or the digital outputs to feed your own external DAC.
Bluetooth 5.0 with 8-Device Memory
Bluetooth 5.0 gives a stable wireless connection. The WTX-1100 remembers up to 8 paired devices. Switching between them is quick. Only one plays at a time.
Aluminum Chassis with LED Indicators
The case is solid aluminum — not plastic. Three blue LEDs on the front show power, connection, and HD codec status. The rear connectors are gold-plated. At 130 × 150 × 47 mm (5.12” × 5.91” × 1.85”), it fits easily on a shelf or in a rack.

Frequently Asked Questions
Frequently Asked Questions
What is aptX HD, and how is it different from regular aptX?
Both are Bluetooth codecs made by Qualcomm. Standard aptX streams at 16-bit/44.1kHz — about the same as a CD. aptX HD streams at 24-bit/48kHz, which is hi-res quality. That means more detail in your music. Your phone needs to support aptX HD too. Most newer Android phones do.
Does the WTX-1100 work with my iPhone?
Yes. iPhones use AAC for Bluetooth, and the WTX-1100 supports AAC. You won’t get aptX HD quality from an iPhone, but AAC still sounds good. For the best quality, use an Android phone with aptX HD.
How do I get the best sound from the WTX-1100?
Use a phone that supports aptX HD. Play music from a hi-res service like Tidal or Qobuz. Connect to your amp with the RCA output. If you have a better external DAC, use the optical or coaxial output instead. Your amp and speakers matter too.
Can I use more than one output at the same time?
Yes. The RCA analog output, optical Toslink, and coaxial RCA all work at the same time. This is handy for comparing your external DAC to the built-in one, or for feeding two devices at once.
How does the WTX-1100 compare to the WTX-Tubes?
Both use aptX HD, Bluetooth 5.0, and the same output types. The difference is the output stage. The WTX-1100 uses a Cirrus Logic CS4344 DAC for clean, neutral sound. The WTX-Tubes adds two vacuum tubes in a Class A circuit for a warmer, softer sound. Pick the WTX-1100 for accuracy. Pick the WTX-Tubes for warmth.
Will there be a delay when watching video?
For music, you won’t notice any delay. For video, there can be a small gap between the picture and the sound. aptX has about 70ms of delay. aptX HD has about 130ms. Most phones adjust for this on their own. If you use the WTX-1100 mainly for music, this won’t matter.
How many devices can it remember?
Up to 8. Your phone, tablet, and laptop can all stay paired. You don’t have to set them up again each time. Only one device plays at a time. Switching is quick.
What else do I need?
A Bluetooth device (any phone, tablet, or computer), an amp with an open input, and RCA cables (not included). The power adapter and antenna come in the box. If you want to use the digital outputs, you’ll need an optical or coaxial cable too. Call us at 800-942-0220 if you need help matching the WTX-1100 to your system.
