SP OT L IG 4. CONTROL ELEMENTS HT Mono and Stereo Input Channels 1 The MONO MIC/LINE Channels Your APM120 is equipped with 8 (12 for APM160) low-noise microphone preamplifiers with optional phantom power, 45 dB of Gain and over 115 dB of S/N ratio. You can connect almost any type of microphone. Dynamic microphones do not need phantom power. Use phantom power only with condenser microphones but make sure that the phantom power button is disengaged before connecting the microphone.
SP OT L IG 4. CONTROL ELEMENTS HT 5 MONO IN GAIN This control is provided with 2 different indications: One is for the MIC and the other for LINE levels. When you use a microphone, you shall read the MIC ring (0~-45dB); when you use a line level instrument, you shall read the LINE ring (+15~-30dB). For optimum operation you shall set this control in a way that the PEAK LED(18) blinks only occasionally in order to avoid distortion on the input channel.
SP OT L IG 4. CONTROL ELEMENTS HT 9 HI If you turn this control up, you will boost all the frequencies above 12 kHz (shelving filter). You will add transparency to vocals and guitar and also make cymbals crispier. Turn the control down to cut all frequencies above 12 kHz. In such way you can reduce Sibilances of human voice or reduce the hiss of a Tape player. 10 MID This is a peaking filter and it will boost/cut frequencies from 100 Hz to 8 kHz depending on the position of the MID freq control.
SP OT L IG 4. CONTROL ELEMENTS HT 15 PAN/BAL Control Abbreviation of PANORAMA control for mono channels, or the stereo channels, always says, BALANCE control. Keep this control in center position, then the signal will be positioned in the middle of stage. 16 MUTE Switch Each channel is equipped with the MUTE switch.

5. INSTALLATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate your APM Series. However, we advise you to read the following section carefully to be the real master of your own mix. Not paying enough attention to the input signal level, the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel: 1.
