- Newly upgraded Bluetooth supports for LDAC, APTX-HD, APTX, AAC, SBC.

Description:
CSR8675 Bluetooth 5.0 is used as digital audio signal receiver. CSR8675 is a powerful and highly integrated wireless audio solution program, which supports for SBC, A2DP, AAC, APTX, APTXLL, APTX-HD lossless digital signal transmission. ES9023 adopts advanced SABRE digital-analog conversion technology. It excels in sound quality and affordable price. Op amp for JRC5532DD is used in analog output part. Socket-style installation way makes it easy to replace op amp for users to improve sound quality. Supports direct replacement of all dual op amp chips.

Bluetooth receiver enables optical, coaxial, analog (RCA), headphone (3.5mm port) outputs. It can be used with digital amplifiers, DAC decoders and traditional AV power amps. It supports 24Bit/192KHz for optical and coaxial signals. It can drive 300Ω headphones.

JC-SQ1, a Bluetooth receiver, can be used as a DAC decoder. When it is connected via Bluetooth, its coaxial port is for SPDIF coaxial digital signal output. When Bluetooth connection is disabled, coaxial port is for SPDIF coaxial signal input. After decoding, it turns to be analog signal (RCA, 3.5mm ports) to output.

The sound quality of Bluetooth receiver is better than that of smartphones in driving headphones. Our receiver first extracts the digital signal of mobile phone audio. After ES9023 decoding, it is converted into analog signal, and then your headphone unit is driven by operational amplifier for JRC5532DD. The effect is much better than that by using an integrated sound card of mobile phone.

Dual ±15V are used to drive op amp part for analog signal. Dual voltage power supply enables perfect dynamics and driving force.

① Power Switch: Turn it upwards to ON to turn on, and turn it downwards to OFF to turn it off.
② Bluetooth Status Indicator: When red and blue lights flash alternately, the device is in searching state (recognized). At this time, mobile phone or tablet computer and other devices turn on Bluetooth to search. The Bluetooth name of our DAC is JC-AUDIO-HIFI or JC-AUDIO-HD. When you find it, click the Bluetooth name to automatically connect. When the screen of mobile phone or tablet computer shows that it is connected, it proves that the device has been connected via Bluetooth. When blue light is on, the device is in Bluetooth connection state.
③ Headphone Jack: 3.5mm headphone jack can directly drive 8-300Ω headphones.
④ Linear Output: RCA left channel output port. It can be directly connected to an amplifier or active speaker.
⑤ Linear Output: RCA right channel output port. It can be directly connected to power amplifier or active speaker.


⑥ Bluetooth External Antenna Interface: Screw on external antenna to enhance Bluetooth signal receiving. Unblocked distance can reach more than 20m.
⑦ Coaxial Signal Interface: Can be used for signal input or output. When Bluetooth is not connected, it is in coaxial signal input mode. At this time, JC-SQ1 can be used as a coaxial signal decoder. When Bluetooth connection is enabled, this interface automatically switches to coaxial signal output mode, which can be connected to a more advanced decoder to decode Bluetooth audio signals. Your mobile phone or tablet PC becomes a Bluetooth digital turntable.
⑧ Optical Fiber Signal Interface: Bluetooth SPDIF signal output, which can be directly connected to a decoder to decode Bluetooth audio signals. There is a customized optical input version, please contact customer service for specific operations.
⑨ Power Input Interface: DC 5V, 3A-6A. Please not use a voltage greater than 5V.
