HD375 is a high-performance HDMI2.0b two-in-one-out audio separation audio extractor. It is  HDMI2.0b inputs and 1 HDMI output with audio extraction function. Support panel buttons, infrared remote control function and automatic switching of plugging and unplugging, support ultra-clear 4Kx2K@ 60Hz, HDCP 2.3, (HDCP removal and crack function), support eARC and ARC functions. Split HDMI audio that supports PCM, 7.1LPCM, DTS, AC-3, Dolby Panorama and HD audio input out of optical, headphone and HDMI AUDIO Only output. It can be used with the HDMI high-definition output of DVD players, Blu-ray players, network players, set-top boxes, PS2, PS3, Xbox360, PC and many other entertainment devices. This product can be used in places with limited noise, transmission distance and safety, data center control, information distribution, conference room presentations, as well as digital environments and corporate training venues.

Features

Audio separation function: separate the input HDMI audio into optical fiber, headphone and HDMI AUDIO Only output;

2 HDMI inputs can be switched freely, panel buttons, infrared remote control function and automatic switching of plugging and unplugging;

Audio mode selection, if the TV does not support 7.1, HD, DTS, it is forced to support it through the switch;

Support ultra-clear 4K*2K@60Hz (YUV444/RGB888), not only 4Kx2k@24/25/30Hz;

Support HDMI version: support HDMI2.0b, backward compatible with HDMI1.0, HDMI1.3, HDMI1.4;

Support HDCP version: HDCP2.3 is backward compatible with HDCP1.4;

Support HDCP removal crack: effectively solve the HDCP compatibility problem of some HDMI devices

Support Audio: Support PCM, 7.1LPCM, DTS, AC-3, Dolby Panorama (only HDMI port support) and HD audio;

Support audio return: eARC/ARC dual mode, perfect solution to the old HDMI amplifier does not support eARC;

Support HDR10/HDR10+;

Support video resolution 480/576/720/1080/4Kx2K@24/25/30/60Hz;

Support 4K60Hz Dolby Vision;

Supports lossless output, that is, separating the audio does not affect the HDMI output, ensuring that the input and output are completely consistent;

In support of ARC mode, HDMI Audio Only can also output synchronously;

The HDMI Audio Only output is fixed to HDMI1.3, and the maximum support is 7.1, which perfectly solves the problem of mismatching power amplifiers.

Connection and operation:

Input mode

1: HDMI loop out: connect the HDMI output port of the set-top box to the HDMI INPUT1 or HDMI INPUT2 input port of the HD375 through the HDMI cable (HDMI cable uses 19 cores + 1), and connect the HDMI OUTPUT output port of the HD375 to the HDMI OUTPUT output port of the HD375 through the HDMI cable. The audio and video are connected to the display terminal such as the TV.

Input method 2: eARC/ARC audio return, connect the HDMI OUTPUT interface of HD375 to the HDMI ARC interface of the audio source equipment such as TV through HDMI cable (HDMI cable uses 19 cores + 1) (Note: Please connect it with ” ARC” marked HDMI interface!), set the audio output mode of the TV and other equipment to ARC output.

2. Connect the HD375 audio output to the power amplifier or active speakers or wired headphones through optical fiber, coaxial, HDMI or 3.5mm audio cable.

3. Connect the USB power cable to the DC 5V interface of the device (choose a charger with an output voltage of 5V 1A (be sure donot use a variable voltage fast charge)).

4. Switch to the corresponding channel by toggling the input audio format switch or input method.

Flexible switching of outputs:

2CH: 2.0 stereo channel output (the audio source needs to be switched to PCM)

5.1CH: Support optical 5.1 digital surround audio (DTS, Dolby, AC3) and other source output; support 24bit/192Khz audio sampling rate

PASS: HDMI output to TV (Note: most TVs only support PCM decoding)

Pay attention to the one-to-one correspondence of the channels, and select the mode switch in the correct connection output mode (the HDMI output TV supports the format of pcm).

5. Finally, connect the DC head of the power adapter to the DC input of the decoder, and then insert the adapter plug into the power socket.

9. TV/2.0/5.1/7.1 switch

Flexible switching of outputs:（Flexible switching output: (Note: do not switch the output channel mode in the working state, and then power on when the switch is not powered on.)）

Flexible switching of outputs:

TV: The output resolution will be based on the EDID displayed on the TV, HDMI audio extraction and separation, 2.0CH audio

The signal is output from 3.5mm, 5.1CH audio is output from optical coaxial, and 7.1CH audio is output from HDMI.

2.0CH: HDMI separated and extracted audio will be output on the 3.5mm interface, HDMI interface and optical coaxial interface, and the audio format is all 2.0 channel PCM format.

5.1CH: HDMI separated and extracted audio will be output on HDMI interface and optical coaxial interface.

(Note: The 3.5mm audio port does not support 5.1 channel, 5.1 channel audio, please disconnect the 3.5mm audio cable.)

7.1CH: The audio format is LPCM, and the audio extracted by HDMI will be output on the HDMI interface.

(Note: If the TV or monitor does not support channel 7.1, there is no audio signal here.)

10. Turn on/off the ARC function (when the ARC input is connected and debugged, the indicator light will be on by short press to turn it on. If there is no ARC signal input for about 10 seconds, it will be off, and you need to press the ARC switch again to turn on)

11. HDMI input switch (button to switch HDMI input signal source)

Common fault judgment and processing methods:

Before turning on the power, you should carefully check whether the connection line is normal, and you must ensure that all interfaces are properly connected.

Common fault judgment and processing methods are as follows:

Trouble phenomenon causes and solutions

1 No power

1. Check whether the power light of the host is on, if not, check whether the power supply or the power cord is correctly connected to the power interface of the host

2. Whether the power supply is DC 5V; whether the current reaches 1000mA

2 No sound

1. Whether the HDMI audio and video separation line is connected well, the indicators are all normal light

2. If ARC is connected, check if the TV supports ARC function

3. The adapter audio format switch is correct

4. Whether the HDMI cable is connected to the HDMI port of the TV that supports ARC

5. Whether the TV has turned on the ARC function (use the TV’s remote control to turn it on)

6. Whether it is an AGW26 standard HDMI2.0 version of the high-definition cable (inferior or HDMI 1.3 version of the high-definition cable without ARC function)

3 There is only noise or abnormality in the RCA interface and headphone interface

1. Set the TV to stereo output (PCM/LPCM 2 channel output)

4 Optical fiber without 5.1 output

1. Check whether the audio format currently playing on the TV is 5.1 channel

2. Set the optical port of the TV to source output (different brands of TVs behave differently, such as Sony TV: “output unchanged compressed audio” or “for multi-channel content, only output unchanged compressed audio” “)

3. The adapter audio format switch is correct
