Components Introduction

Top Panel:

1. LCD Screen
   To show the device status intuitively. Please refer to the following “Screen Display” for more information.

2. MIX Knob
   In Recording mode, to adjust volume level of the output audio from Line Output ports; In Streaming mode, to adjust volume level of the output audio from 3.5mm and USB-C ports；the volume indicators will change according to the volume level.

3. Volume Indicator
   Indicating the volume level of the output audios.

4. Recording/Streaming Mode Switch Button
   Short press to switch between Recording mode and Streaming mode.
   AD5 outputs stereo audio in recording mode, IN1 stands for the left channel, and IN2 the right channel; AD5 outputs mono audio in streaming mode.

5. Mute Touch Button
   Touch to turn on/of Mute.

6. Denoise Touch Button
   Touch to turn on/switch/turn of denoise. Please switch to denoise 1 mode when using dynamic mics; Please switch to denoise 2 mode when using condenser mics.

7. EQ/REV Touch Button
   Long press to switch to EQ or Reverb; short press to choose EQ/REV modes.

Front Panel:

1. Input Port IN1/2
   6.35 TRS instruments and XLR micrphones can be connected to AD5 through the input ports IN1/2. In Recording Mode, IN1 stands for the left channel and IN2 the right channel.

2. Gain Control Knob 1/2
   Adjust the preamp gain for input signals at IN1/2 respectively.

3. 48V Phantom Power Switch 1/2
   Turn on/of 48V Phantom Power. When you turn this switch on, phantom power will be supplied to the XLR jack connected to the IN1/2 ports. Please turn it on when using a phantom powered microphone.
   1. When connecting/disconnecting microphones to AD5, please set the gain of AD5 to the minimum before turning on/of 48V Phantom power to avoid damaging the devices.
   2. When connecting devices not requiring 48V phantom power to IN1/2 port, please make sure to turn of 48V phantom power.

4. Inst Switch 1/2
   Turn on/off the input impedance. Please turn the inst switch on when connecting Hi-Z instruments such as an electric guitar/bass to achieve better input effects.
   1. It’s recommended to set the gain of AD5 to the minimum before turning on/off Inst switch to avoid feedback problems and damage to the devices.
   2. When connecting devices not requiring high inpedance to IN1/2 port, please make sure to turn off Inst switch.
   3. To protect your speaker system, leave the monitor speakers turned off when turning the Inst switch on/off.

5. 3.5mm Monitoring Port 1
   Plug in 3.5mm TRS/TRRS headphones to monitor.

6. Monitoring Mode Switch
   Switch monitoring mode. In direct monitoring mono mode, the monitoring audio is mono; In direct monitoring stereo mode, the monitoring audio is stereo (IN1 stands for the left channel and IN2 the right channel); In direct monitoring mode, AD5 will route the audio signals from IN1/2 directly to the monitor outputs and headphones with zero latency. In input monitoring mode, audio signals from IN1/2 will be routed to the DAW software and then to the monitor outputs and headphones with mixed audio, which will cause a delay in monitoring.

7. Loopback Switch
   Loopback uses the ‘virtual’ inputs, which have no physical connectors on the audio interface itself but can directly route the digital signal streams back to DAW software, it can capture all the audio signals from your computer(e.g., the audio signal output from a web browser) to input to the audio interface.
   Short press to turn on/of Loopback. When Loopback is on, AD5 will output audio signals both from IN1/2 and USB-C ports; When Loopback is o, AD5 will output
   audio signals from IN1/2 ports.
   Loopback only affects the audio output of the USB-C port, not the 3.5mm port.

8. Monitoring Volume Control Knob
   In Recording mode, to adjust monitor volume level of the 3.5mm ports; In Streaming mode, to adjust monitor volume level of the 3.5mm and Line Output ports.

Back Panel:

1. Power/Language Switch Button
   Long press to turn on/off; short press to switch the language of AD5
   between Chinese and English.

2. USB-C Charging Port
   Users can charge AD5 through the 2 in 1 cable.

3. USB Port 1/2
   To connect phones/computers to input/output audio signals via the 2 in 1 audio cable. Phones/computers can route audio singals to AD5 and AD5 can achieve the digital output of audio signals from both phones/computers and IN1/2.

4. 3.5mm Port 1/2
   To connect phones to input/output audio signals via the 3.5mm TRRS-TRRS audio cable. Phones can route audio signals to AD5 and AD5 can achieve analog output of the audio signals from phones and IN1/2. The 3.5mm port can capture all the audio signals from your phone(e.g., the audio signal from a guest on the phone) to AD5. The audio signal from the phone won’t be routed back. Thus the guest on the phone can hear the whole podcast mix, but without their own voice. This type of mix is
   known as ‘mix-minus’.

5. 3.5mm Monitoring Port 2
   Plug in 3.5mm TRS/TRRS headphones to monitor.

6. Line Output Port
   Connect to the monitor speakers, L means the left channel and R the right channel.

7. Reset Hole
   If the device cannot be charged or is unable to function, insert the reset pin into the reset hole to reset it.
