XLR + 1/4’’ jack combo (balanced and unbalanced). The microphone
preamplifier with differential (balanced) input mode provides a clear signal and
limits noise.
2. TALK OVER switch
Set this switch to “ON” to reduce the volume of channel 1, channel 2 and the USB
device, so that the microphone signal stands out. Set this switch to the “OFF”
position to switch off this Talk Over function.
3. Gain adjustment
This function adjusts the microphone signal. If the signal is too strong, turn the
button to the left, and vice versa.
4. High frequency gain adjustment
This equipment can increase or reduce signals with a center frequency of 10 KHz
by12dB.
5. Low frequency gain adjustment
This equipment can increase or reduce signals with a center frequency of 100 Hz
by 12dB.
6. Volume control
This dial allows you to precisely control the volume level.

14. Mid frequency gain adjustment
Allows you to adjust (+12dB/-26dB) signals with a center frequency of 1.1KHz.
15. High frequency gain adjustment
Allows you to adjust (+12dB/-26dB) signals with a center frequency of 14KHz.
16. CH1 control dial
Allows you to have a 30mm linear decrease, and can control the level precisely.
17. CH2 control dial
Allows you to have a 30mm linear decrease, and can control the level precisely.
18. CD1 and LINE1 selected switch
Select the CD input or line input.
19. CD2 and LINE2 selected switch
