Following page picture shows the PBM8.350 UM standard connections for a live set.

Connect three or more microphones to mono MIC channels (1~3); connect keyboards or signal processors to either line input of stereo channel 7~8 or line input of mono channel; connect the CD player to line input of mono or stereo channel; other stereo line signal source can be connected to line input of channel 9~10.

You can connect either an external amplifier or active speaker to the monitor output jack. Using the main output jacks on front panel, you can connect an external power amplifier to driving the 1 or 2 sub-woofers or 2 active speakers. Besides, you can connect a pair of headphone to headphone output jack. On the rear panel, there are powered mix output connectors , you can connect to these powered connectors 2 passive speakers.

You can use the AUX1 output jack to connect a powered stage monitor, or the stage monitor external power amp.

If needed, you can also use the 2-track in/out connectors to connect the DAT or cassette for recording.

output controls are turned down. This will avoid damages to your speakers as well

as excessive noise.

3.3 Please connect a passive speaker to your PBM8.350 UM speakon connector or

1/4 '' jack(#35). Otherwise ,you can connect a pair of active speakers directly to

your PBM8.350 UM Main Out Left & Right 1/4 '' jacks(#18).

3.4 Complete these connections as illustrated.

3.5

When no external power amplifier or active speaker is connected to the main output L/R of your PBM8.350 UM, please switch on your PBM8.350 UM after turning on all external devices. After your live set, switch off your PBM8.350

UM before all external devices.

3.6 When the external power amplifier or active speaker is connected to the main output L/R of your PBM8.350 UM please switch on your PBM8.350 UM before the external power amplifier or active speaker. After your live set, switch off your PBM8.350 UM after the external power amplifier or active speaker.

4. CONTROL ELEMENTS

4.1 MONO/STEREO Input Channel Section

Your PBM8.350 UM comprises 6 mono input channels and 2 stereo input channels, each of them including

-20dB PAD, 3-band equalizer, AUX sends, PAN and

LEVEL controls. The following content will detail the each part.

1 MONO Input Channels (1 ~ 6)

CH1 through Ch6 are provided of MIC IN and LINE IN connector. Use the XLR MIC IN connector to connect low noise microphones preamp and low level signal, which also feature +48V phantom power, allowing you to connect condenser microphones. Use the 1/4" TRS

LINE IN connector to connect either a microphone or a line level instrument such as synthesizers, drum machines, effects processors...

Note: You shall never connect an unbalanced microphone to the XLR connector if you do not want to damage both the microphone and the mixer.

2 STEREO Input Channels (7 ~ 10)

CH7 through CH10 are organised in stereo pair. Via the

1/4" TRS input connectors, you can connect the outputs from stereo devices such as synthesizers, effects processor or any stereo line level signal. If only the left jack was connected, the input will operate in mono mode.

Via the XLR MIC IN connector, you can connect the low level sources.

3 -20dB PAD Button

Pressing this button will attenuate the input signal by

20dB. In such way you can produce increased headroom and reduce the risk of distortion due to quite "hot" signals.

4 EQUALIZER

Your PBM8.350 UM features a 3-band equalizer allowing you to adjust the high, mid and low frequencies separately o n e a c h c h a n n e l . A l l b a n d s p r o v i d e a b o o s t or cut up to 15dB , flat at the center detent.

4. CONTROL ELEMENTS

HIGH

This is the treble control. You can use it to get rid of high frequency noises or to boost the sound of cymbals or the high harmonics of the human voice.

MID

This is the midrange control. It affects most fundamental frequencies of all musical instruments and human voice. An attentive use of this control will give you a very wide panorama of sound effects.

LOW

This is the bass control. It is used to boost male voice , kickdrum and bass guitar. Your system will sound much bigger than what it is.

MON (AUX1) Control

Your PBM8.350 UM has two auxiliary sends which can be used for sending signals to external or internal effects device or for creating a monitor mix, these sends are used to adjust the level of respective channel signal sent to

AUX bus, and the adjustable range goes from - to +10dB. The AUX1 control is configured as PRE-FADER, which means that the signal is sent out before reaching the channel fader. It is used for a stage monitor mix in a live set, or for a headphone mix in recording application.

DSP/FX (AUX2) Control

The AUX2 control is configured as POST-FADER, so the AUX send level will be affected by channel fader. Via the AUX2 OUT jack, the AUX2 signal can be sent to an external effects device, furthermore, the AUX2 signal can also be assigned to internal onboard effect module.

PAN Control

Abbreviation of PANORAMA control for mono and stereo channels. It is used to determine the amount of channel signal sent to main mix left and right outputs. Keeping this control in center position, the signal will be positioned in middle of "stereo field". Turn this control fully counterclockwise, the signal will be present only on the left of main mix and vice-versa.

Channel LEVEL Control

This control is used to adjust the overall level of respective channel. The adjustable range goes from - to +10dB.

4.2 MASTER SECTION Controls

6. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your PBM8.350 UM. 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 corrupt signal or no sound at all. So you should follow this procedure for every single channel:

Turn down all Input and output controls.

Connect phantom powered microphones before switching on the +48Volt

phantom power switch.

Set the output level of your PBM8.350 UM or the connected power amplifier

at no more than 75%.

Now, set the MONITOR level at no more than 50%. In this way you should

monitor your mix, connecting a pair of headphones or a pair of powered studio

monitor speakers.

Position EQ controls on middle position.

Position panoramic (PAN) control on center position.

Properly increase the input gain for maintaining a good headphone and ideal

dynamic range.

Depending on the actual application, turn slowly the input and output level

controls for obtaining the maximum gain before distortion.

Now repeat the same sequence for all input channels. The main LED meter

could move up into the red section. In this case you can adjust the overall

output level through the MAIN MIX control.

6.1 Audio Connections

You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.

STEREO GRAPHIC EQ

Your PBM8.350 UM is equipped with a stereo graphic EQ for MAIN MIX, and a mono EQ for MONITOR MIX. Each EQ provides 9-band fader controls. Via these faders, you can boost/attenuate the selected frequency up to 15dB at a preset bandwidth. When all faders are at the center position, the equalizer output is flat response. They are used to modify the frequency "contour" of a sound. Since there is no bypass switch, the EQ function will be activated as soon as you turn on your PBM8.350 UM.
