1MIC/LINEMONOINPUT(1to6)

Your PBM8 is equipped with 6 low-noise microphone preamplifiers with optional phantom power, 50 dB of Gainandover90dBofS/Nratio.Youcanconnect 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.
