FIIO SP3 BT from Official Japanese Number FIIO Active Speaker Desktop Bluetooth [Ships store/Serial Included] (Black)

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Stable performance using high-class Bluetooth chip Qualcomm QCC5124: Qualcomm QCC5124 is used as the Bluetooth chip. Dual DSP and Dual-core design provide reliable and stable performance even with high bit rate sound sources. Compatible with Bluetooth codec LDAC / aptX Adaptive / AAC: Bluetooth supports all major codecs. Supports SBC / AAC / aptX / aptX-LL, including LDAC, aptX Adaptive, and aptX HD, which realize high-resolution wireless. If you connect with LDAC, you can secure a transmission bit rate of up to 990kbps and enjoy delicate and rich sound quality of 96kHz/24bit. Equipped with a rich variety of input interfaces such as USB Type-C, coaxial, and optical digital, ensuring further expandability: In addition to analog audio input, SP3 BT newly supports USB Type-C, coaxial, and optical digital input. It allows for flexible connections from sound source devices, and allows for simple wiring configurations. The expanded input interface makes it easier to connect to a variety of new devices, expanding the range of applications that suit the scene. *Supported sampling rates for USB Type-C, coaxial, and optical digital input are 44.1kHz, 48kHz, and 96kHz. Other sampling rates are not supported. Equipped with a 3.5-inch large-diameter midwoofer that uses a carbon fiber diaphragm: The SP3 BT is equipped with a 3.5-inch large-diameter midwoofer in a compact housing. The woofer's diaphragm is made of highly rigid and lightweight carbon fiber material, suppressing unnecessary resonance and achieving excellent dynamics and sound field expression. Furthermore, the internal and external magnetic circuit design, which places magnets inside and outside the voice coil, achieves a powerful magnetic flux of up to 1.2 Tesla, maximizing the potential of the woofer. Equipped with a 25mm silk dome tweeter that enables high-quality high-frequency reproduction: The SP3 BT is equipped with a 25mm silk dome tweeter that uses a KSV copper-clad aluminum wire voice coil that enables ultra-wideband reproduction. Sound-absorbing material is placed inside the diaphragm to absorb unnecessary sound waves, and a large space behind the magnetic circuit effectively suppresses back pressure on the driver. We have achieved a rich mid-to-high range that is the core of music. In addition, by controlling the directivity of the mounting surface using a waveguide, a wide sweet spot is achieved, making it possible to create an ideal sound field even on a desktop with little flexibility. Equipped with an S-shaped bass reflex port that improves low-frequency expression: SP3 BT is equipped with an S-shaped bass reflex port structure to achieve both a compact housing and high-quality low-frequency expression. This S-shaped port has a carefully designed length and diameter to properly control airflow, achieving a low frequency response of 65Hz (±2dB). Achieving a clear and deep bass range that exceeds the cabinet size. Equipped with a multi-amplifier circuit with 2-way active crossover: In order to maximize the performance of the two drivers, the SP3 BT uses a multi-amplifier circuit configuration with separate amplifiers for the tweeter and woofer. The signals sent to each driver amplifier are accurately separated by an active crossover circuit. Each signal divided by the 3.4kHz crossover is driven by Texas Instruments' class D amplifier module "TPA3118". The multi-amplifier configuration provides 30W drive power to the woofer and 10W drive power to the tweeter, which not only reduces intermodulation distortion, but also avoids overload and significantly improves power efficiency. In addition, the power supply circuit, which has a power supply capacity of 100W, uses two large Nichicon 4700uf capacitors to provide a clean and stable power supply to the amplifier circuit, providing a sense of scale and drive power that exceeds its class despite the compact housing. Compact aluminum die-cast housing: The SP3 BT housing is made of aluminum die-cast material. Suppresses resonance that adversely affects sound quality and effectively dissipates heat from the amplifier section. Furthermore, it plays a role in preventing electromagnetic interference from outside. It was designed with consideration given to achieving both high sound quality and space saving on the desk. Equipped with standby function and automatically starts according to usage: SP3 BT is equipped with a standby function and automatically enters standby mode if there is no input signal for about 20 minutes. It starts up immediately when a signal is detected, eliminating cumbersome operations and allowing for intuitive use. Supports the Bluetooth control app "FIIO Control" and allows for your favorite tuning with 10-band parametric EQ: SP3 BT supports connection with the Bluetooth control app "FIIO Control" to further enhance your listening experience. From "FIIO Control", you can tune to your desired sound quality by selecting the Bluetooth codec to connect and setting the Q value and gain of each band using the 10-band parametric EQ. Additionally, the SP3 BT has an equalizer on the back that allows you to adjust the low frequency level from -8dB to 0dB. This allows you to adjust the bass appropriately depending on the song, preference, and installation location. The desktop speaker "SP3 BT", which achieves excellent dynamics and sound field expression, is back with long-awaited Bluetooth support!
