(1). PEAK LED INDICATOR This LED indicators lets you check the level of the signal input to the channel. The peak indicator lights when the input signal reaches 5dB below the channel’s clipping point. This indicator shows the level of the Post-EQ / pre-fader signal. If the PEAK indicator lights more than briefly on high-level transients, you should use the GAIN control to decrease the input sensitivity of the channel. If this does not work, reduce the output level of the connected source.
(2). GAIN CONTROL According to the level of the input signal, use this knob to adjust the input to an appropriate level. The best balance of S/N and dynamic range will be achieved if you adjust the GAIN control so that the peak indicator lights
occasionally. This control adjusts the channel’s mic input sensitivity between
-50dB and -6dB and the line input sensitivity between -30dB and +14dB. The mono/stereo combination input channels have a sensitivity of +20dB to
-20dB.
(3). HPF (High-Pass Filter, cut frequencies below 75Hz) This switch toggles the HPF on or off. To turn the HPF on, press the switch in ( ).
(4). 3 BAND EQUALIZER CONTROLS This is a 3-band equalizer with center frequencies, range and type as shown below. The frequency response is flat when all knobs are in the “0” position.
(5). AUX CONTROLS This knobs control the level of the signals sent to AUX bus. This control is placed before the channel volume; it will not be affected by the channel level volume.
(6). EFX CONTROLS This knobs control the level of the signals sent to EFX bus. The channel signals mixed by this bus have their overall level set by the EFX SEND Control to the EFX SEND jack on the front panel. Since this control is placed after the channel fader, the signal level will be affected by the channel fader setting.

FRONT PANEL CONTROLS – CHANNEL CONTROL SECTION (continued)
(7). PAN /BAL CONTROL
PAN (Mono Channel) This control pans the channel signal across the master L and R buses, thus determining the perceived position of the sound from that channel in the output stereo sound field. If a PAN control is set all the way to the left, for example, the sound from that channel will be heard from the left speaker system only. If it is set all the way to the right, the sound will be heard from the right speaker system only. Intermediate settings will cause the sound to appear at corresponding locations in the stereo sound field.
BALANCE (Stereo Channel) This control adjusts the balance or the L/R position of the stereo input signal. Turning the BALANCE control to the left of center moves the apparent source toward the MAIN L moves the source toward the MAIN R bus.
(8). CHANNEL LEVEL VOLUME This is the channels main level control. It determines the level of the signal that is sent from the channel to the master mixing and effect buses. It is the settings of the input channel faders that determine the mix, or the balance of sound levels between the instruments or other sources connected to the inputs. When a channel is not being used, its volume should be set at the minimum position to prevent the addition of unwanted noise to the main program signal.

FRONT PANEL CONTROLS – MAIN CONTROL SECTION
(1). PHANTOM POWER INDICATOR
This indicator lights when the phantom power switch is turned on.
(2). PHANTOM POWER SWITCH This switch toggles phantom power on or off. If you set the switch on, the mixer supplies power to all channels that provide XLR microphone input jacks. Set this switch on when using one or more condenser microphones.
WARNING, be sure the microphone you are using is compatible or will not be affected by phantom power. Failure to do so may result in equipment damage. Please see the notes below:
NOTE: When this switch is on, the mixer supplies DC +48V power to pins 2 and 3 of all XLR-type MIC INPUT jacks.
NOTE: Be sure to leave this switch off ( ) if you do not need phantom power.
NOTE: When the switch is pressed on ( ), be sure that only condenser microphones are connected to the XLR input jacks. Note, however, that the switch may be left on without problem when connecting to balanced dynamic microphones. Be sure the balanced dynamic microphone you are using is not affected by phantom power in any way before connection is made. The same applies with ribbon microphones.
NOTE: When the switch is pressed on ( ), do not use single-ended (unbalanced) microphones or instruments into the XLR input jacks. Do not plug
instrument outputs into the XLR input jack unless you know for certain it is safe to do so.
NOTE: To avoid damage to the speakers, be sure to turn off the amplifier (or powered speakers) before turning this switch on or off. We also recommend that you turn all controls (MAIN L/R, CTRL ROOM / HEADPHONE, etc) to minimum settings before operating the switch, to avoid risk of loud noises that could cause hearing loss or device damage.
(3). TAPE IN CONTROL This control adjusts the level of the playback signal that is inserted to the master mixing bus from the TAPE IN RCA jacks on the top panel.
(4). STEREO RETURN CONTROL Adjust the level of the mixed L/R signal sent from the RETURN jack (L (MONO) and R) to the Main L/R bus.
(5). CTRL ROOM /PHONES CONTROL Controls the level of the signal output to the HEADPHONE jack and the CONTROL ROOM L and R jacks.
(6). MAIN L/R MASTER VOLUME This volume adjusts the final level of the combined signals from all channels.
(7). OUTPUT LEVEL METER A vertical row of ten LED shows the continuous output level of MAIN OUTPUT L/R. This type of display is highly visible
under poor lighting conditions. The 0 LED means an output level of +4dB for +4dB output (that’s the rated level).
(8). POWER INDICATOR This indicator lights when the power switch is turned on.

FRONT PANEL CONTROLS – INPUT/OUTPUT CONNECTORS
(1). Channel Input Jacks MIC JACKS
A 3-pin XLR-type connector is used for balanced low impedance microphone inputs. (pin 1: sleeve, 2: hot, 3:cold)
BALANCED LINE IN JACKS A standard 1/4” phone jack is used for balanced or unbalanced line level signals. Examples of line level signals include most electronic keyboards, synthesizers, turn-tables (with appropriate pre-amps), tape decks and the line outputs from other mixers.
(2). CHANNEL INSERT I/O JACK These are input/output jacks located between the head-amplifier and the high pass filter. These jacks allow you to use graphic equalizers, compressors, noise filters, or other devices.
(3, 4). CHANNEL INPUT JACKS These are unbalanced stereo line input jacks. Two jack types are provided phone type and RCA pin type.
(5). TAPE IN JACKS These RCA pin jacks input a stereo sound source. Use these jacks when you want to connect a CD or DAT directly to the mixer for monitoring.
NOTE: You can adjust the signal level using the TAPE IN control in MAIN control section.
(6). REC OUT JACKS The REC OUT jacks send the pre-fader signal from the master bus for recording by the tape deck.

FRONT PANEL CONTROLS – INPUT/OUTPUT CONNECTORS (continued)
(7). SEND JACKS
* AUX: These are unbalanced phone jacks-type output jack. This jack output the signal form AUX bus, respectively. You use this jack, for example, to connect to an effector or to a cue box or other such monitoring system. * EFX: These are unbalanced phone jacks-type output jack that output the signal form the EFFECT bus. You use this jack, for example, to connect to an external effector
(8). RETURN L (MONO), R Jack These are unbalanced 1/4” phone-type line input jacks. The signal received by these jacks is sent to the MAIN bus and AUX bus. These jacks are typically used to receive a return signal from an external effect (reverb, delay, etc.)
NOTE: These jacks can also be used as an auxiliary stereo input. If you connect to the L (MONO) jack only, the mixer will recognize the signal as monaural and will propagate the identical signal on both L and R jacks
(9). MAIN L/R OUTPUT JACKS These jacks deliver stereo output of the mixer signal. You use these jacks, for example, to connect to the power amplifiers driving your main speakers. You also use these jacks when you wish to record the signal utilizing the level control applied by the main volume in the main Control section.
(10). CONTROL ROOM OUTPUT JACKS Use these stereo phone-type output jacks to connect to your monitor system.
NOTE: The main output signals also route to these jacks controlled by the CTRL ROOM / PHONES volume.
(11). HEADPHONE JACK Connect for headphones. This is stereo phone-type output jack (3-conductor TRS).
NOTE: The main output signals also route to these jacks controlled by the CTRL ROOM / PHONES volume.

POINTS TO REMEMBER
(1). AC ADAPTOR IN CONNECTOR
Connects to the included power adaptor. NOTE: Use only the adaptor included with this mixer. Use of a different adaptor may result in fire or electric shock.
(2). POWER SWITCH Use this switch to turn mixer power to ON.
- In all cases, use good quality twin screened audio cable. Check for instability at the output.
- Always connect both conductors at both ends, and ensure that the screen is only connected at one end.
- Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety and
screen returns to the system start point.
- Equipment which has balanced inputs and outputs may need to be electrically isolated from the equipment rack
and/or other equipment, to avoid earth loops.
It is important to remember that all equipment which is connected to the mains is a potential source of hum and interference and may radiate both electrostatic and electromagnetic radiation. In addition, the mains will also act as a carrier for many forms of RF interference generated by electric motors, air-conditioning units, thyristor light dimmers etc. Unless the earth system is clean, all attempts to improve hum noise levels will be futile. In extreme cases there will be no alternative but to provide a completely separate and independent ‘technical earth’ to replace the incoming ‘noisy earth’. However, always consults your local electricity supply authority to ensure that safety regulations are not being infringed.

capabilities. typically the feeds to the mix are implemented on rotary level controls. an aux return on the mixer is intended to connect to the output of the supplemental equipment.
balance the relative levels of the left and right channels of a stereo signal.
balanced a method of audio connection which ‘balances’ the wanted signal between two wires and a
screen which carries no signal. any interference is picked up equally by the two wires, which results in cancellation of the unwanted signal.
clipping the onset of severe distortion in the signal path, usually caused by the peak signal voltage being
limited by the circuit’s power supply voltage.
DAT Digital Audio Tape, a cassette-based digital recording format.
dB (decibel) a ratio of two voltages or signal levels, expressed by the equation dB=20Log10 (V1/V2). Adding
the suffix ‘u’ denotes the ratio is relative to 0.775V RMS.
DI (direct injection) the practice of connecting an electric musical instrument directly to the input
of the /DI Box mixing console, rather than to an amplifier and loudspeaker which is covered by a microphone feeding the console.
direct output a post fade line level output from the input channel, bypassing the summing amplifiers, typically
for sending to individual tape tracks during recording.
equalizer a device that allows the boosting or cutting of selected bands of frequencies in the signal path.
fader a linear control providing level adjustment.
feedback the `howling’ sound caused by bringing a microphone too close to a loudspeaker driven from its
amplified signal.
foldback a feed sent back to the artistes via loudspeakers or headphones to enable them to monitor the
sounds they are producing.
frequency response the variation in gain of a device with frequency.
gain the amount of amplification in level of the signal.
headroom the available signal range above the nominal level before clipping occurs.
highpass filter a filter that rejects low frequencies and passes only high frequencies. the cut-off frequency
determines the limit that frequencies are rejected or allowed to pass through.
impedance balancing a technique used on unbalanced outputs to minimize the effect of hum and interference when
connecting to external balanced inputs.
22
GLOSSARY (continued)
insert a break point in the signal path to allow the connection of external devices, for instance signal
processors or other mixers at line level signals. Nominal levels can be anywhere between -10dBu to +6dBu, usually coming from a low impedance source.
pan (pot) abbreviation of ‘panorama’: controls levels sent to left and right outputs.
peaking the point at which a signal rises to its maximum instantaneous level, before falling back down
again. It can also describe an equalizer response curve affecting only a band of frequencies, (like on a graphic equalizer), “peaking” at the centre of that band.
peak LED a visual indication of the signal peaking just before the onset of clipping.
PFL a function that allows the operator to monitor the pre-fade signal (pre-fade listen) in a channel
independently of the main mix.
phase a term used to describe the relationship of two audio signals. In-phase signals reinforce each
other, out-of-phase signals result in cancellation.
polarity a term used to describe the orientation of the positive and negative poles of an audio
connection. Normally connections are made with positive to positive, negative to negative. If this is reversed, the result will be out-of-phase signals (see ‘phase’ above).
post-fade the point in the signal path after the monitor or master fader and therefore affected by fader
position.
pre-fade the point in the signal path before the monitor or master fader position and therefore
unaffected by the fader position.
rolloff a fall in gain at the extremes of the frequency response.
shelving an equalizer response affecting all frequencies above or below the break frequency i.e. a
highpass or lowpass derived response.
spill acoustic interference from other sources.
transient a momentary rise in the signal level.
unbalanced a method of audio connection which uses a single wire and the cable screen as the
signal return. This method does not provide the noise immunity of a balanced input (see above).
+48V the phantom power supply, available at the channel mic inputs, for condenser
microphones and active DI boxes.

(1). TÉMOIN DE CRÊTE Ces témoins permettent de vérifier le niveau du signal d'entrée au canal.
Les témoins de crête s’allument lorsque le signal d'entrée atteint 5 dB en
dessous du point d'écrêtage du canal. Ces indicateurs montrent le niveau
du signal après l’égaliseur et avant le fader. Si les témoins de crête restent
allumés pendant les transitoires de haut niveau, vous devez diminuer la
sensibilité d'entrée du canal à l’aide du bouton GAIN. Si cela ne marche
pas, réduisez alors le niveau de sortie de la source connectée.
(2). CONTROLE DE GAIN Selon le niveau du signal d'entrée, utilisez ce bouton pour régler l'entrée sur un niveau approprié. Le meilleur équilibre du Rapport signal/bruit et de la gamme dynamique sera atteint si vous réglez le GAIN de manière que les témoins de crête ne s'allument que de temps en temps. Ce bouton permet de régler la sensibilité du canal d'entrée du micro entre
-50dB et -6dB et la sensibilité d'entrée ligne entre-30dB et +14 dB. Les canaux d'entrée mono/stéréo combinés ont une sensibilité de 20 dB à
-20dB.
(3). HPF (Filtre passe-haut, fréquences de coupure inférieure à 75Hz) Ce bouton permet d’activer/désactiver le HPF. Enfoncez le bouton ( ) pour activer le filtre HPF.
(4). BOUTONS DE L’ÉGALISEUR 3 BANDES Il s'agit d'un égaliseur 3 bandes avec fréquences, gamme et type moyens comme indiqué ci-dessous. La réponse en fréquence est nulle lorsque tous les boutons sont en position "0".
(5). BOUTONS AUX Ces boutons contrôlent le niveau des signaux envoyés au bus AUX (auxiliaire). Avant signifie non affecté par la position du fader du canal.
(6). BOUTONS EFX Ces boutons contrôlent le niveau des signaux envoyés au bus EFX. Les signaux du canal mélangés par ce bus ont leur niveau global fixé par le bouton EFX SEND vers le connecteur EFX SEND du panneau avant. Le signal du bus EFX est également introduit dans le processeur de signal numérique interne. Etant donné que ce bouton est placé après le fader du canal, le niveau du signal sera affecté par le réglage du fader du canal.

BOUTONS DU PANNEAU AVANT - SECTION CONTROLE DE CANAL (suite)
(7). BOUTON PAN/BAL
PAN (canal mono) Ce bouton effectue un panoramique du signal du canal à travers les bus maîtres L (gauche) et R (droite), déterminant ainsi la position du son perçu de ce canal dans le champ sonore de sortie stéréo. Si un bouton PAN est positionné à fond vers la gauche, par exemple, le son à partir de ce canal sera reproduit par le système d’enceintes gauche uniquement.
S’il est positionné à fond à droite, le son sera reproduit par le système d’enceintes de droite uniquement. Une position
intermédiaire fera apparaître le son à des endroits correspondants dans le champ sonore stéréo.
BALANCE (canaux stéréo) Ce bouton permet de régler la balance ou la position L (gauche)/R (droite) du signal stéréo d'entrée. Tourner le bouton BALANCE vers la gauche par rapport au centre fait déplacer de la source apparente vers MAIN MIX L (gauche), fait déplacer la source vers le bus MAIN MIX R (droite).
(8). FADER DE CANAL Il s'agit du contrôle du niveau principal des canaux. Il détermine le niveau du signal qui est envoyé depuis le canal vers le mixage principal et les bus d'effets. Ce sont les réglages des faders des canaux d'entrée qui déterminent le mixage, ou la
balance des niveaux sonores entre les instruments ou les autres sources connectées aux entrées. Lorsqu’un canal n'est
pas utilisé, son volume doit être réglé à la position minimale pour empêcher l'ajout de bruit indésirable au signal du programme principal.
