FiiO SA1 High-Fidelity Desktop Speaker

31-band high-precision lossless PEQ
Be your own pro audio engineer
The SA1, unlike most similar products, supports a 31-band high- precision lossless PEQ that can be used in all input modes. Through the FIIO Control app, you can fine-tune and calibrate the frequency response curve. For problems such as non-flat frequency response curves caused by complex room reverberation and standing waves, you can take control and optimize the sound thanks to the PEQ.

Variety of inputs and outputs Find everything you need
The SA1 is a pair of active speakers with a wide variety of inputs and outputs when compared to similarly-priced products. It includes RCA and 3.5mm analog inputs; a built-in DSP; supports USB, coaxial, and optical digital inputs as well as high-res Bluetooth input. Particularly noteworthy of the SA1 is the built-in phono preamp, allowing even entry-level products to shine.The SA1 is also equipped with a subwoofer output, allowing the SA1 active speakers to perfectly fit within your home theater setup. The SA1 covers most usage cases for listeners looking for a speaker within its price range.

RCA/PHONO IN: Standard RCA and phono inputs.
AUX IN: Standard 3.5mm stereo analog line input.
USB IN: Type-C digital input, supports up to 96kHz/32bit.
COAX IN: Standard RCA coaxial digital input, supports up to 192kHz/24bit.
OPT IN: Standard Toslink optical digital input, supports up to 96kHz/24bit.

Supports LDAC high-res Bluetooth
Enjoy the best of wireless sound
In addition to a variety of analog and digital inputs, the SA1 also supports LDAC high-definition Bluetooth decoding and Bluetooth version 5.4, which allow for wireless high-bit-rate audio up to 990kbps for richer sound. Thanks to the high-resolution digital inputs and LDAC support, the SA1 is both Hi-Res Audio and Hi-Res Audio Wireless certified.

Multiple built-in sound presets
Supports app control
The SA1 comes with eight sound presets and allows you to save up to three custom PEQ setups, all of which can be adjusted through the FIIO Control app. In addition to the typical pop, jazz, classical, R&B, and dance sound presets, there is also a specially-tuned monitoring-style curve that compensates the frequency response curve to a flat line, allowing the SA1 to transform into active desktop studio monitor speakers.

3.5-inch wood fiber woofer
Compact yet powerful
Although the SA1 is an entry-level product, its woofer is the same 3.5-inch size as that of the SP3/SP3 BT and is made of the same wooden fiber pulp manufacturing process as in FT1 wood headphones. The pure pulp fiber diaphragm is both lightweight and sturdy, and outputs rich sound. By adjusting the pulp material, ratio, and the proportion of long and short fibers, we made the diaphragm more rigid and fine-tuned the sound. The wooden fiber diaphragm has a thick and rich sound, with dense and lush vocals. Due to these advantages, it is no wonder that other well-known brands utilize this kind of driver in their speakers even now. Additionally, the 3.5-inch woofer is paired with a large 75mm flexible suspension, allowing that driver to achieve bass extension down to 65Hz.

3/4 inch aluminum-magnesium alloy dome tweeter
Silky smooth to your ears
The SA1 uses a monitor-grade aluminum-magnesium diaphragm dome tweeter that provides with crisp, clear sound. It brings a uniquely enjoyable listening experience with plenty of detail.

Texas Instruments digital amp
Guaranteed good sound
Being a desktop active speaker, the internal amplification is extremely important. The SA1, like the SP3/SP3 BT, is equipped with two Texas Instruments TI TPA3118 Class D digital amplifiers. The main and auxiliary speakers each are driven in four ways, with woofer output power up to 20W*2 and tweeter output power up to 5W*2. The TPA 3118 has high conversion efficiency and features low noise, ensuring the purity of the audio signal.

Acoustic design 2.0
Active electronic two-way crossover
The SA1 is designed to be a set of professional active speakers. The crossover point is set at 3.5kHz, which best suits the characteristics of the drivers, power supply, and circuitry – maximizing the SA1’s sound quality. The SA1 employs a two-way second-order active filter circuit to enhance the flexibility and control precision of the crossover. This crossover design effectively isolates each driver's signal from the others–leading to reduced intermodulation distortion, avoided driver overload,and significantly improved power efficiency.

Built-in phono preamp
For beginners or experts
The SA1 is equipped with a built-in phono preamp, designed with standard RIAA equalization in order to ensure faithful reproduction of sound from your vinyl records. When using a vinyl turntable without a built-in preamp (vinyl turntable only has PHONO OUT), you can switch the SA1 to the PHONO setting to use the internal SA1 phono preamp. If the vinyl turntable already has a built-in preamp (such as the FIIO TT13), simply switch the input toggle to RCA IN.
