SP OT L IG 4. 3. CONTROL ELEMENTS HT 1 MIC/LINE MONO INPUT (1 to 6) Your PBM8 is equipped with 6 low-noise microphone preamplifiers with optional phantom power, 50 dB of Gain and over 90 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. 3. CONTROL ELEMENTS HT 5 DSP/FX The AUX2 control is configured as POST-FADER, so the audio signal will be affected by channel LEVEL control and sent to the resident digital multi-effect. Via the AUX2 OUT jack, the AUX2 signal can be sent to an external effects device, and in such case the resident digital multi-effects will be automatically disconnected.

SP OT L IG 4. 3. CONTROL ELEMENTS HT 15 MONITOR LEVEL CONTROL This control is used to adjust the level of the monitor output. 16 MAIN MIX LEVEL CONTROL This control is used to adjust the overall volume of the main mix output. 17 MAIN MIX LEVEL LED DISPLAY This LED display will show you the Main Mix output level. Make sure that the +10 LED only lights up occasionally. The optimal level is when the -10 and 0 LED light up.
SP OT L IG 4. 3. CONTROL ELEMENTS HT 21 MONITOR OUT JACK Use this balanced MONITOR jack to connect the input of an external amplifier or active monitor speaker. 22 MAIN OUT JACKS These jacks are used to output the Main Mix signal to an external amplifier or active speaker. 23 HEADPHONE OUT JACK This is a stereo phone type output jack. It is used to send out the Main Mix signal to a pair of headphones. 24 AUX2 OUT JACK The phone jack is used to output the line level signal of the AUX2 post fader bus.

5. INSTALLATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate your PBM8. However, we advise you to read carefully the following section to be the real master of your own mix. Not paying attention enough to the input signal level, to 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.
