1.  Introduction

Caution!
We should like to draw your attention to the fact that extreme volumes 
may damage your hearing and/or your headphones or loudspeakers. 
Turn the MAIN MIX faders and phones control in the main section 
fully down before you switch on the unit. Always be careful to set the 
appropriate volume.
1.1  General mixing console functions
A mixing console fulfils three main functions:
Signal processing: Preamplification, level adjustment, mixing of effects, 
frequency equalization.
Signal distribution: Summing of signals to the aux sends for effects 
processing and monitor mix, distribution to one or several recording tracks, 
power amp(s), control room and 2-track outputs.
Mix: Setting the volume level, frequency distribution and positioning of the 
individual signals in the stereo field, level control of the total mix to match 
the recording devices/crossover/power amplifier(s). All other mixer functions 
can be included in this main function.
The interface of BEHRINGER mixing consoles is optimized for these tasks enabling 
you to easily keep track of the signal path.
1.2  The user’s manual
The user’s manual is designed to give you both an overview of the controls, 
as well as detailed information on how to use them. In order to help you 
understand the links between the controls, we have arranged them in groups 
according to their function. If you need to know more about specific issues, 
please visit our website at http://behringer.com, where you’ll find explanations 
of e.g. effects and dynamics applications.
1.3  Before you get started
1.3.1  Shipment
Your mixing console was carefully packed in the factory to guarantee safe 
transport. Nevertheless, we recommend that you carefully examine the 
packaging and its contents for any signs of physical damage, which may have 
occurred during transit.
◊ 
If the unit is damaged, please do NOT return it to us, but notify your 
dealer and the shipping company immediately, otherwise claims for 
damage or replacement may not be granted.
1.3.2  Initial operation
Be sure that there is enough space around the unit for cooling purposes and to 
avoid over-heating please do not place your mixing console on high-temperature 
devices such as radiators or power amps. The console is connected to the 
mains via the supplied cable. The console meets the required safety standards. 
Blown fuses must only be replaced by fuses of the same type and rating.
◊ 
Please note that all units must be properly grounded. For your own 
safety, you should never remove any ground connectors from electrical 
devices or power cables, or render them inoperative.
◊ 
Please ensure that only qualified people install and operate the 
mixing console. During installation and operation, the user must have 
sufficient electrical contact to earth, otherwise electrostatic discharges 
might affect the operation of the unit.

2.  Control Elements and Connectors
This chapter describes the various control elements of your mixing console. 
All controls, switches and connectors will be discussed in detail.
2.1  Mono channels
2.1.1  Microphone and line inputs
Fig. 2.1: Connectors and controls of mic/line inputs
MIC
Each mono input channel offers a balanced microphone input via the XLR 
connector and also features switchable +48 V phantom power supply for 
condenser microphones. The XENYX preamps provide undistorted and noise-free 
gain as is typically known only from costly outboard preamps.
◊ 
Please mute your playback system before you activate the phantom 
power supply to prevent switch-on thumps being directed to your 
loudspeakers. Please also note the instructions in chapter 2.4.2 
“Voltage supply, phantom power and fuse”.
LINE IN
Each mono input also features a balanced line input on a ¼" connector. 
Unbalanced devices (mono jacks) can also be connected to these inputs.
◊ 
Please remember that you can only use either the microphone 
or the line input of a channel at any one time. You can never use 
both simultaneously!
