+48V If you are about to use condenser microphone, turn Phantom power switch ON to feed your microphone with 24/48V. If you use dynamic microphone or microphone with his own power, you can switch this OFF. |
![]() |
PAD If you are using microphone as an input, this button should be set to “Off” position. If you are using input from the mixing console or CD player, please set this switch to “On” position. |
![]() |
COMP (Compressor/Limiter operation button) To provide perfect output signal without clipping or distortion, you can switch the Comp button ON. If you switch this OFF, signal in output could contain signal clipping or distortion. |
![]() |
HPF (High Pass Filter) This button helps to avoid distributing low-end rumble like a microphone handling noise or pops. You have 2 options – full range or 160Hz low-cut frequency. The one you choose depends on the sound, you want to filter out. |
![]() |
OSC (Oscillator operation switch) To test signal level, which is coming to the outputs, you can switch this Test 1kHz sine signal oscillator on. After recipients set the levels in their recording devices, you should switch this function OFF. When compressor switch is set to ON, output signal level won’t exceed this maximum output level. |
