3. QUICK START
This is the fastest way to get something out from your PBM8, if you have a keyboard and a microphone.
a.Plug the microphone into Channel 1 MIC IN.
b.Turn down AUX and LEVEL controls on the input channel.
c.Turn down MONITOR and MAIN master controls.
d.Put the EQ controls on center position.
e.Connect 2 passive cabinets to the rear speaker cabinets or 2 active cabinets to the front MAIN OUT connectors.
f.Turn on your PBM8.
g.Sing or speak into the microphone with normal volume and adjust the channel LEVEL control of half.
h.If you like, you can add some equalization at this stage.
i.Turn up the MAIN LEVEL control until you reach the desired volume. The +10 LED on the Master LED meter should flash only occasionally, otherwise you will hear the distortion. If this LED is not active and you still hear distortion, please turn down a little the input LEVEL control or reduce the output level of your source instrument.
j.Connect your stereo keyboard into channel 7/8 and repeat the sequence.
Here you are. It is your first gig with your PBM8.

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. Phantom power will not damage your dynamic microphones but it may damage tube or ribbon microphones. So make sure to read the microphone instructions manual before engaging phantom power. Use switch (19) to activate/deactivate phantom power. These 6 channels are also equipped with 1/4" TRS balanced/unbalanced LINE-IN plugs to connect line-level instruments such as keyboards, drum machines and effect devices.
NOTE: Never try to connect a line-level signal to the XLR MIC input when the phantom power is engaged, or you may seriously damage your equipment.
2 MIC/LINE STEREO LINE INPUTS
These are channels 7/8 and 9/10. They are organised in stereo pair and provided with XLR balanced socket and 1/4" TRS phone sockets. If you connect only the left jack, the input will operate in mono mode, that is the mono signal will appear on both input channels. You can use these inputs with a stereo keyboard, drum machine, etc.
3 LEVEL CONTROL
This control is used to adjust the overall level of respective channel. The adjustable range goes from 
to +10 dB.
4PAN
This is the PANORAMA control, or balance control. You can adjust the stereo image of the signal via this control. Keep this control in center position and your signal will be positioned in the middle of stage. Turn this control fully counter clockwise and the signal will be present only on the left speaker and vice-versa. Of course a large number of intermediate positions are available.
