FIIO K7BT. Bluetooth Amplifier/DAC. Black

Introducing the FiiO K7BT, the Bluetooth version of the renowned FiiO K7 that offers the same structure with the addition of wireless connectivity. This device incorporates Bluetooth 5.1 and can handle high-resolution audio codecs such as LDAC, aptX Adaptive and aptX LL, among others. With standout features such as two gain levels, a dual AK4493SEQ DAC and a THX AAA 788+ amplifier, the FiiO K7BT ushers in an era of superior power and exceptional wireless performance.

The FiiO K7BT features a six-stage audio design with balanced analogue and digital sections that minimise interference and enhance sound reproduction. Equipped with the THX AAA 788+ amplifiers from the K9 Pro, the K7BT delivers an output of 560 mW into 300-ohm headphones and 2000 mW into 32-ohm headphones, both with 1% distortion. This allows for optimal compatibility with both low and high impedance headphones, delivering a listening experience that really gets to the heart.

The K7BT's Bluetooth HD technology ensures smooth, low-latency transmission with high-resolution sound. Through its dedicated app, the wireless experience is significantly enriched. In addition, the AK4493SEQ DAC guarantees refined and detailed sound, enabling musical rediscovery. The XMOS XUF208 decoder handles multiple audio formats efficiently thanks to its dual-clock management.

Additionally, the K7BT features RGB indicator lights that add a touch of colour and dynamism to any space. Intelligent overheat and overload protection systems ensure safe and efficient operation in a variety of environments. With an advanced power design that includes multiple independent, low-noise LDO-regulated stages, the K7BT is designed to deliver clear and powerful energy for a superior listening experience.

The FiiO K7BT is adaptable for a variety of uses and is compatible with both headphones and powered speakers, offering standard and balanced connection options. The aluminium build quality, coupled with a sleek black finish and gold accents of the THX and Hi-Res Audio badges, complemented by RGB lights, give it a luxurious and modern look. The smooth volume wheel with 112 steps of adjustment ensures precise control for all your audio devices.
