1 / 2 S400/S450 Product Instruction Manual 一：S400/S450 Product Instruction Manual S400/S450 is a new high fidelity multifunctional audio playback device with built-in DSP+20 EQ sound processing and independent sound algorithm. Supports Bluetooth 5.3, allowing devices such as TVs, computers, mobile phones, set-top boxes, etc. to be actively connected to S400/S450 devices via wireless Bluetooth to play music. 二：Performance characteristics and indicators 1: Power input: 20V/3.6A 2: Frequency response 50Hz-20kHz 3: Signal to noise ratio>65dB 4: Distortion<5% 1000 Hz 5: Output power (2.1 mode) (2 * 9W+1 * 35W) 8: Impedance 4 Ω 2 / 2 三：system connection The early S400/S450 system will perform color coding on speaker wires and subwoofer labels. The later products will have a combination of color coding and shape. The modular seats have specific socket sleeves that are easy to connect. 四：Precautions for use Improper use during operation may damage the S400/S450 audio equipment. The following methods can extend the usage time of S400/S450. The normal operating temperature of audio equipment is 0 º C-45 º C. (32 º to 113 º) If exposed to excessively high ambient temperatures for a long time, it may damage internal components and accelerate the aging of electrical components. The control panel of S400/S450 should not be directly exposed to sunlight and exposed heat sources. 3. During the playback process, avoid continuously increasing the maximum volume. An appropriate volume can prolong the playback time and delay the use of electrical components.
