Introduction

You can use this product to record high-quality audio on your computer.
Not only record the human voice through the microphone input port; also can record the instrument sound of an electric guitar or bass through the instrument input port of the ¼-inch (6.35 mm) jack; at the same time, you can connect the physical output to the speaker, active monitors, headphones or any other audio equipment for real-time monitoring.

Operation Interface

1 3 INST switcher – blue LED indicates that high ohmage state is selected, gain range and input impedance will be changed.
2 4 +48V – phantom power switch for microphone input – enables 48V phantom power at the XLR socket (required for professional studio condenser microphones)
5 USB LED – The LED light will be powered when connect to computer
6 PHONES – knob adjusts the output level at the headphones output.
7 GAIN 1 – adjust the input gain level for the channel 1.
8 10 Line – “Combo” input sockets – connect microphones, instruments (e.g., guitar), or line level signals here. Combo sockets accept both XLR and ¼” (6.35 mm) jacks. Microphones connect using XLR plugs; instruments and line level signals should be connected via ¼” (6.35 mm) jack plugs of either TS or TRS type.
9 Volume VU meter – used for confirming sign level Green = signal, Red = clipping, CLIP LED indicates that the audio signal in the channel is too loud. Turn the corresponding GAIN knob counter-clockwise until the CLIP LED no longer light.
11 GAIN 2 – adjust the input gain level for the channel 2.
12 DIRECT MONITOR – this switch determines how input sources are to be monitored and steps between three Direct Monitoring modes: OFF, MONO and STEREO. When set to OFF, monitoring of input sources is via the DAW; in MONO or STEREO, monitoring is taken directly from the preamp inputs and is therefore free of any possible latency effect.
13 – adjust the output signal level of the [LINE OUTPUT]. OUTPUT ¼ ”-to-
14 – ¼ ” TRS output jack. If your headphones have a ¼ ” TRS jack plug, connect them directly; if they have a 3.5 mm TRS “mini jack”, use a TRS 3.5 mm jack adaptor. Note that it is likely that headphones fitted with 4-pole TRRS plugs will not operate correctly.
15 The anti-theft lock hole.
16 LINE OUTPUTS LEFT and RIGHT – 2 x ¼ ” (6.35 mm) TRS jack sockets; connect to powered studio monitors.
17 USB 2.0 Type-C connector – Connect to a computer via this connector.

Fault Detect

1. Not working after connecting?
   We recommend replacing the USB-C cable to retest and check whether the connection is correct and firm.

2. How to confirm successful contacted with your computer by USB data cable?
   (1) Windows
   Step 1: Connect this product with computer via USB cable;
   Step 2: Computer open device manager;
   Step 3: The selected “Sound, video and game controllers” shows the device name ” USB AUDIO DEVICE” of the product.
   (2) Mac OS
   Step 1: Open the settings in the Mac OS System Prefrences;
   Step 2: Find the sound;
   Step 3: Select the device ” USB AUDIO DEVICE ” for sound input
   When you need to monitor through this product, open the settings in the Mac OS System Prefrences, find the sound, and then select the device ” USB AUDIO DEVICE ” for sound output.
   

3. Does it make noisy when use?
   We recommend that you only connect the USB-C cable, turn on the monitor, and it is normal to hear the current sound with headphones, and it indicates the product is no problem; if there are other noises, you can try to re-plug or replace the cable.

NOTE

1. The microphone input port uses a standard 3-pin XLR socket, which is compatible with most types of microphones.
2. Mac, Windows10 or above driver-free installation, you can install [ASIO4ALL] if you have special needs.
