Introduction

XENYX Mic Preamps

The microphone channels feature high-end XENYX Mic Preamps that compare well with costly outboard preamps in terms of sound quality and dynamics and boast the following features:

• 130 dB dynamic range for an incredible amount of headroom
• A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear reproduction of even the finest nuances
• The extremely low-noise and distortion-free circuitry guarantees absolutely natural and transparent signal reproduction
• They are perfectly matched to every conceivable microphone with up to 60 dB gain and +48 volt phantom power supply
• They enable you to use the greatly extended dynamic range of your 24-bit/192-kHz HD recorder to the full, thereby maintaining optimal audio quality

“British EQ”

The equalizers used for the XENYX Series are based on the legendary circuitry of top-notch consoles made in Britain, which are renowned throughout the world for their incredibly warm and musical sound character. Even with extreme gain settings these equalizers ensure outstanding audio properties.

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 amplifiers). 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.

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. The illustrations at the beginning of each chapter show the controls described in each respective chapter.

• The block diagram supplied with the mixing console gives you an  overview of the connections between the inputs and outputs, as well as the associated switches and controls.

For the moment, just try and trace the signal path from the microphone input to the FX send connector. Don’t be put off by the huge range of possibilities; it’s easier than you think! If you look at the overview of the controls at the same time, you’ll be able to quickly familiarize yourself with your mixing console and you’ll soon be making the most of all its many possibilities.

If you need to know more about specific issues, please visit our website at http://behringer.com, where you’ll find explanations of (for example) effects and dynamics applications.

Before you get started

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.

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.

• Never connect the XENYX to the power supply unit when the latter is connected to the mains! First connect the power supply unit to the console, then connect the power supply unit to the mains.
• 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.

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.

Mono channels

Microphone and line inputs

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 2.3.5 “Phantom power and LED displays”.

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!

GAIN

Use the GAIN control to adjust the input gain. This control should always be turned fully counterclockwise whenever you connect or disconnect a signal source to one of the inputs.

Equalizer

All mono input channels include a 3-band equalizer, except for the 502, which is equipped with a 2-band EQ. All bands provide boost or cut of up to 15 DBV . In the central position, the equalizer is inactive.

The circuitry of the British EQs is based on the technology used in the best-known top-of-the-line consoles and providing a warm sound without any unwanted side effects. The result are extremely musical equalizers which, unlike simple equalizers, cause no side effects such as phase shifting or bandwidth limitation, even with extreme gain settings of $15 DBV.

The equalizer of the mono input channels

EQ

The upper (HIGH) and the lower band (LOW) are shelving filters that increase or decrease all frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower band are 12 kHz and 80 Hz respectively. The mid band (1202/1002/802) is configured as a peak filter with a center frequency of 2.5 kHz.

LOW CUT

In addition, the mono channels (1202 and 1002) are equipped with a steep LOW CUT filter (slope at 18 dB/oct., -3 dB at 75 Hz) designed to eliminate unwanted low-frequency signal components.

FX sends, panorama and level adjustment

The FX send/panorama/level controls

FX (1202/1002/802 only)

FX sends (or AUX sends) enable you to feed signals via a variable control from one or more channels and sum these signals to a bus. The bus appears at the console’s FX send output and can be fed from there to an external effects device. The return from the effects unit is then brought back into the console on the aux return connectors (802) or normal channel inputs. Each FX send is mono and features up to +15 dB gain.

As the name suggests, the FX sends of the XENYX mixing consoles are intended to drive effects devices (reverb, delay, etc.) and are therefore configured post-fader. This means that the mix between dry signal and effect remains at the level determined by the channel’s aux send, irrespective of the channel fader setting. If this were not the case, the effects signal of the channel would remain audible even when the fader is lowered to zero.

PAN

The PAN control determines the position of the channel signal within the stereo image. This control features a constant-power characteristic, which means the signal is always maintained at a constant level, irrespective of position in the stereo panorama.

LEVEL

The LEVEL control determines the level of the channel signal in the main mix.

CLIP

The CLIP LED’s of the mono channels illuminate when the input signal is driven too high, which could cause distortion. If this happens, use the GAIN control to reduce the preamp level until the LED does not light anymore.

Stereo channels

Stereo line inputs

LINE IN

Each stereo channel has two balanced line level inputs on ¼” jacks for left and right channels. If only the jack marked “L” (left) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals. Both inputs will also accept unbalanced jacks.

Equalizer stereo channels (802)

The XENYX 802 features a stereo 3-band EQ in each stereo channel. The filter characteristics and cut-off frequencies are the same as those in the mono channels. A stereo EQ is highly preferable to two mono equalizers. When working on a stereo signal, as two separate EQ’s will usually produce an unwanted discrepancy between the left and right channels.

The equalizer of the stereo input channels

FX sends, balance and level adjustment

The FX send/balance/level controls

FX

The FX sends of the stereo channels function similar to those of the mono channels. However, since the FX send buses are both mono, a mono sum is first taken from the stereo input before it is sent to the FX bus. The 502 is not equipped with FX sends.

BAL

The BAL(ANCE) control determines the levels of left and right input signals relative to each other before both signals are then routed to the main stereo mix bus. If a channel is operated in mono via the left line input, this control has the same function as the PAN control used in the mono channels.

LEVEL

The LEVEL control determines the volume of the channel being sent to the main mix.

+4/-10

The stereo inputs of the XENYX 1202 and 1002 have an input sensitivity switch which selects between +4 DBV and -10 DBV. At -10 DBV (home-recording level), the input is more sensitive (requires less level to drive it) than at +4 DBV
(studio level).

Connector panel and main section

Send/return effects path

FX send/return connectors

FX send/return controls

AUX RETURN

802 only: the STEREO AUX RETURN connectors are used to bring the output of the external effects device (whose input is derived from the aux sends) back into the console. You can instead use these connectors as additional inputs, but any effects device will then have to be brought back into the console via a normal stereo channel. This does, however, give you the ability to use the channel EQ on the effects return signal if you wish.

• When using a stereo channel as effects return path, the FX control of the relevant channel should generally be turned fully down to avoid undesirable feedback.

If only the left connector is used, the AUX RETURN automatically operates in mono. Use the AUX RETURN control to determine how much of the effects signal is sent to the main mix.

FX SEND

The FX SEND output (does not apply for 502) should be connected to the input of an external effects unit. The post-fader FX signal you created using the input channel FX controls is sent to the effects unit via the FX SEND output. Use the FX SEND control of the main section to adjust the overall send level (1002 and 1202 only).

Monitor and main mix

PHONES/CONTROL ROOM

The stereo PHONES jack (at the top of the connector panel) is where you connect headphones. The unbalanced CTRL ROOM OUT jacks carry the summed effects and main mix signals, as well as soloed channel signals. The PHONES/CONTROL ROOM control adjusts the level of both headphones and main monitor outputs. The 502 is not equipped with control room outputs.

Monitor/main mix connectors

MAIN MIX

The MAIN OUT connectors are unbalanced mono jacks. The main mix signal appears here at a level of 0 DBV. The MAIN MIX fader adjusts the volume of these outputs. The XENYX 802 and 502 mixing consoles feature a rotary control for this purpose.

Monitor control and main mix fader

2-Track connectors

2-TRACK INPUT

The 2-TRACK INPUTs are used to bring an external signal source (e.g. CD player, tape deck, etc.) into the console. They can also be used as a standard stereo line input, so the output of a second XENYX or BEHRINGER ULTRALINK PRO MX882 can be connected.

 2-Track input/output

Alternatively the line or tape output of a hi-fi amplifier with source selection switch could also be hooked up here, allowing you to easily listen to additional sources.

2-TRACK OUTPUT

These connectors are wired in parallel with the MAIN OUT and carry the main mix signal (unbalanced). Connect the 2-TRACK OUTPUT to the inputs of your recording device. The output level is adjusted via the high-precision MAIN MIX fader or rotary control (802).

Signal assignment

Assignment switches of the main section

2-TR TO MIX

When the 2-TR TO MIX switch is depressed, the 2-track input is assigned to the main mix providing an additional input for tape machines, MIDI instruments or other signal sources that do not require any processing.

2-TR TO CTRL ROOM (502: 2-TR TO PHONES)

Press the 2-TR TO CTRL ROOM/PHONES switch if you want to monitor the 2-track input via the CTRL ROOM OUT. This provides an easy way to monitor signals coming back from tape to ensure that they are recording correctly.

• If you are recording a signal via the 2-TRACK OUTPUT and wish to listen to this simultaneously via the 2 TRACK INPUT, do not use the 2-TR TO MIX switch. Doing this would create a feedback loop, since the signal
  would be routed, via the main mix, back to tape via the 2-TRACK OUTPUT. To monitor the 2-TRACK INPUT, use the 2-TR TO CTRL ROOM switch to assign the tape signal to the monitors) or headphones. This will avoid the tape signal being routed to the 2-TRACK OUTPUT.

FX TO CTRL

If you want to monitor only the FX send signal in your headphones or monitor speakers), press the FX TO CTRL switch. This mutes the main mix signal while routing the FX SEND output to the monitors). The XENYX 802 and 502 do not feature this switch.

Phantom power and LED displays

Phantom power and control LEDs

+48 V

The red +48 V LED lights up when phantom power is on. The PHANTOM switch activates the phantom power supply on the XLR connectors of all mono channels.

• Please do not connect microphones to the mixer (or the stage box/ wall box) as long as the phantom power supply is switched on. Connect the micro-phones before you switch on the power supply. In addition, the monitor/PA loudspeakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute in order to allow system stabilization.

POWER

The blue POWER LED indicates that the console is powered on.

Level indicator

The high-precision 4-segment display accurately displays the relevant signal level.

LEVEL SETTING: To correctly set the gains of the channels, first set the LEVEL controls of the input channels to their center positions (0 dB). Then use the GAIN controls to increase the input amplification until signal peaks show O dB on the level meter.

When recording to digital recorders, the recorder’s peak meter should not go into overload. While analog recorders can be overloaded to some extent, creating only a certain amount of distortion (which is common and often desirable), digital recorders distort quickly when overloaded. In addition, digital distortion is not only undesirable, but also renders your recording completely useless.

• The peak meters of your XENYX display the level virtually independent of frequency. A recording level of 0 dB is recommended for all signal types.

Installation

Mains connection

AC POWER IN

Connect the power supply to the 3-pin mains connector on the rear of the console. Use the AC adapter supplied to connect the console to the mains.

The adapter complies with all applicable safety standards.

• Please use only the power supply unit provided with the console.
• Never connect the XENYX to the power supply unit while the latter is connected to the mains. First connect the console to the power supply unit, then connect the power supply unit to the mains.
• Please note that both the power supply unit and the mixing console heat up considerably during operation. This is completely normal.

Audio connections

You will need a large number of cables for different applications. The illustrations below show how the connectors should be wired. Be sure to use only high-grade cables. Please use commercial RCA cables to connect the 2-track inputs and outputs. You can, of course, also connect unbalanced devices to the balanced inputs/ outputs. To do this, use either mono plugs or stereo plugs with the ring and  sleeve bridged (pins 1 and 3 in the case of XLR connectors).

Caution! Never use unbalanced XLR connectors (PIN 1 and 3 connected) on the MIC input connectors when using the phantom power supply.
