Feature 1. This mixer uses ultra-low impedance circuits and professional balanced input and output to minimize noise and achieve incredible quietness. Each input channel is equipped with a split microphone preamplifier, not a standard integrated circuit, but a paired ultra-low-noise transistor that operates at high current, making the product quality rich in the low frequency band and clear in the mid frequency band.
Cabinet installation instruction We recommend ensuring at least 11 U of cabinet space. Including the cable connecti on to the computer, we recommend at least 13 U of cabinet space. 10U is about 445mm, 11U is about 489mm, 12U is about 533mm, 13U is about 577mm, and 14U is about 623mm.

Function introduction 1:PHANTOM+48V switch and indicator light Use this switch to turn phantom power on or off. When this switch is on, DC+48V power can be applied to the XLR input socket. When the switch is on, the indicator light will light up. An independent phantom power switch for each MIC channel.

Function introduction 5:Stereo input jack LINE(L/MONO,R) This input jack is an unbalanced phone type line stereo input jack. 6:Stereo input jack LINE(L,R) This input jack is used to connect line-level instruments, such as electronic keyboards and audio equipment. Two jack types are available: phone type and RCA pin type. Note: On any given channel, you can use either a phone jack or an RCA jack, but not both together.If both types of jacks are used at the same time, only the phone jack...

Function introduction 11:Equalizer knob This three-band equalizer adjusts channels in three frequency bands: high/mid/low. Setting this knob to the position produces a flat frequency response. Turning the knob to the right enhances the corresponding frequency band, while turning the knob to the left Frequ ency bands that can be attenuated.

Function introduction 1. Output part 20:SEND socket (AUX1-4) These are impedance-balanced phone-type output jacks. These jacks output the signal from AUX1-4 respectively. These jacks can be used, for example, to connect to an effector or prompt box or other monitoring system. 21: MONITOR OUT jack These impedance- balanced TRS phone...

Function introduction 27:SEND MASTER AUX1-4 control adjusts the output to the AUX1-4 jack signal level. Note: SEND 4 controls entry into digital effects at the same time signal size of the transmitter. 28:ST switch at GROUP If this switch is turned on, the mixer will send the signal processed by the GROUP fader to the stereo bus.

Function introduction 33:POWER (power) indicator light This indicator light lights up when the mixer is powered on. 34:Level meter The LED display indicates the signal level (the signal level sent to the C-R OUT and PHONES jacks) by the selector switch mentioned in 31 above. Corresponds to the "0" point of the standard output level.
