4. CONTROL ELEMENTS 1 4.1 The MONO MIC/LINE Channels These are channel 1 through channel 8. You can connect balanced, low impedance microphones to the XLR socket. On the 1/4" phone jack you can connect either a microphone or a line level instrument. You shall never connect an unbalanced microphone to the XLR socket if you do not want to damage both the microphone and the mixer. MIC 1 2 1 3 1 48 Volt phantom power LINE IN 1 2 It is available only to the XLR Mic sockets.
6 4.5 STEREO INPUTS These are Channel 9 through 12. They are organised in stereo pair and provided with 1/4" TRS phone sockets. If you connect only the left jack, the input will operate in mono mode. 4.6 +4dBu/-10dBV Switch LINE IN 9/10 LINE IN 11/12 LEFT (MONO) LEFT (MONO) 6 7 Your PM-12 provides the gain select switch, which is used to adjust the sensitivity of line input on stereo channels.

Your system will sound much bigger than what it is. The gain range goes from -15dB to +15dB and the center frequency is 80 Hz.
4.12 FADER 17 This fader will adjust the overall level of this channel and set the amount of signal sent to the main output or the corresponding subgroup output. SG/PEAK SG/PEAK MUTE 18 4.13 ASSIGNMENT Switches MUTE 10 10 dB dB 5 Each channel provides three assignment switches: SUB1-2, SUB 3-4 and MAIN L-R.

4.18 SUBGROUPS Control Section - SUBGROUPS ASSIGN TO MAIN MIX 30 Through these switches, you can operate the subgroup faders as a master control for assigning the subgroups to MAIN MIX. Engage the LEFT switch to send the corresponding subgroup signal to MAIN MIX L, and the RIGHT switch for MAIN MIX R. When engaging the both switches, the signal will be sent to L/R of MAIN MIX.
