[INPUT
1 GAIN] Knob Determines the basic volume of channel 1. Adjust the controller to make the corresponding [PEAK] LED (2) flash briefly when singing and playing at the maximum volume -
[MIC/LINE 1] [PEAK] Indicator
It will light up when the input signal is too large. The indicator will light up when the input signal level is lower than 38 of clipping distortion. Set the optimal recording level adjustment [INPUT GAIN] knob so that the [PEAK] indicator flashes briefly at the maximum input volume! -
[MIC/LINE 1] [SIG] Indicator
Itwill light up when there is an input signal. When the input signal level is too low, when the indicator does not light up, adjust the [INPUT GAIN] knob so that the [SIG] indicator light is always on when speaking -
[INPUT
1 HI-Z] Switch Inputimpedance switch(On / Off). When connecting a high- impedance instrument such as an electric quitar or electric bass directly to the [MIC / LINE 1] jack, you can turn on the switch. When the switch is turned on, the instrument and the [MIC / LINE 1] jack can be connected with an unbalanced phone plug.
Note: To protect your speaker system, please turn off the monitor speakers when turning on/off the
[INPUT
1 HI-Z] switch. Itis also a good way to adjust all output level controllers to the minimum gear.
Failure to observe these precautions will produce loud sudden noises that may damage your equipment and hearin -
[MIC/LINEL] Jack
Used to connect microphones or digital musical instruments. This jack can be connected to both XLR type plugand phone type plug (balanced/unbalanced), MIC (LXR) / LINE (TRS).
Note: Pharttom power will supply power to the XLR plug which i cannected to the [MIC / LINE 2] Jack -
STEREO/MONO switchable switch
Valid for all MIC signals, when pressed, the signal from the [MIC/LINE 1/2] jack will be output to both channel of the [MAIN OUT L/R jack and the L/R channel of [PHONES] jack. -
[IMIC/LINE 2] Jack
Used’to connsct micraphones,digital musical instruments, electrc guitarsorelecric basses. This jack an be connected to both XLR type plugs and phone-type plugs (balanced/unbalanced)
Note: Phantom power will be supplied to the XLR plug which is connected to the [MIC / LINE 2] jack -
[MIC/LINE 2] [PEAK] Indicator
It will light up when the input signal is too large. The indicator will light up when the input signal level is lower than 3d8 of clipping distortion. Set the optimal recording level adjustment [INPUT GAIN] knob so that the [PEAK] indicator flashes briefly af the maximum input volume. -
[MIC/LINE 2] [SIG] Indicator
Itwill light up when there is an input signal. When the input signal level is too low, when the indicator does not light up, adjust the [INPUT GAIN] knob 5o that the [SIG] indicator light is always on when speaking -
[INPUT 2 GAIN] Knob

[High Speed USB 2.0] Port
Used to connect to computers or i05 devices.
Note: When connecting to the computer via [USB2.0] port, please observe the following to prevent data damage.
Note: Please observe the following precautions before connecting or disconnecting the USB cable.
Quitall application software running on the computer.Set all output level controllers to the minimun value.
Please wait at least 6 seconds between connecting/disconnecting the USB cable.
Note: When the sound card is connected to an iOS device, Apple accessories may be required -
[Transfer switch]
Used to select the power supply port of the sound card. To use bus power via the [USB2.0] port, set the switch to the [USB2.0] side. To supply power through the [V DC] port, st the switch to the [5V DC] side -
[5V DC) (5V DC) Port
Used to connect USB power adapter or USB mobile battery. When Q24 connecting to devices that do not have sufficient bus power, such as iPad, use the power supply. (The USB power adapter and USB mobile battery are notincluded when the sound card
is sold)
Notice:Please carefully read the safety precautions for the USB power adapter or USB mobile battery.
Please use a USB power adapter with a 5-pin micro USB plug or a USB mobile battery. Output voltage 4.8V to 5.2V,
Output current 0.9 A or above, please Use [SV DC] port. Evenif the sound card is connected to the computer, when the switch s set to the [SV DC. You can still use an external power supply through the [5V DC] port. This can avoid power supply problems. For example, i the equipment connected to the sound card shares the same power outlet with the computer, the difference in voltage may cause ground loops. If the power supply to the computer’s USB port is unstable, it will also cause a decrease in sound quality. -
[+48V] switch
Turn on/off phantom power . When the switch is turned on, the phantom power will supply power to the XLR plug connected to the [MIC / LINE 1/2] jack.When using a phantom-powered condenser microphone, turn on the switch,
Note: When using phantom power, check the following items to prevent noise and damage to the Q22 or connected equipment.Do not connect or disconnect any devices when the phantom power is on. When setting the phantom power to on or off, adjust all output level controls to the minimum When the connected device does not need to provide phantom power to the [MIC/HI-Z 1/2] jack, be sure to turn off the phantom power.
Note: When the phantom power switch is turned on and off all input/output ports will be muted for a few seconds. -
[GROUND] Zero-potential grounding point. If noise or exchange hum occurs when the equipment is connected to a PC or other power supply equipment, a clean earth wire can be connected to this point to reduce and eliminate interference.

Fault resolution
Power indicator is off ?
Setting of the transfer switch correct?
When power is not supplied to the device, the power indicator is off. When
using an AC adapter, move the switch to the [SV DC] jack, and move the switch
to the [USB 2.0 jack to provide bus power (computer only).
The power indicator blinks continuously
If the power is insufficient, the indicator light will continue to flash. Move
the switch to the [V DC} jack, and then use the USB power adapter or USB
mobile battery to supply power.
Confirm whether the correct USB cable is used Be sure to use the included USB
cable.
No sound
Confirm whether the correct USB cable is used. Be sure to use the included USB
cable.
Is the volume control of this device set to the correct level?
Confirm the [OUTPUT] knob and [PHONES] knob.
Are the microphone and monitor speakers properly connected to the device?
Please refer to the “Manual” to confirm the correctness of the connection.
Is the power switch of the monitor speaker turned on?
Make sure the switch of the monitor speakers is turned on.
Abnormal sound (noise, interruption or distortion) Does the computer meet the
system requirements?
Confirm system requirements. The PC operating system is too old, reconfigure
the PC operating system. Check whether the recording level is overloaded, it
is recommended to set the recording level at OdB (OdB= IV).
Are you recording or playing long continuous audio?
The computer’s audio data processing capability depends on many factors,
including CPU speed and access to external devices, reducing the audio track
and then checking the sound again.
Is the microphone properly connected to the device?
Connect the microphone to the device with an XLR type plug.
If you use a phone plug, the volume may be insufficient.
(TRS is only used for LINE input)
