Precautions

1. Location

Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity — such as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation or vibration which could cause mechanical damage and locations subject to strong electromagnetic ﬁelds, such as close to broadcast equipment.

2. Ventilation

The unit has ventilation slots on the bottom panel. Do not block these vents.

3. Avoid Physical Shocks

Strong physical shocks to the unit can cause damage. Handle it with care.

4. Do Not Open the Case or Attempt Repairs or Modiﬁcations Yourself

This product contains no user-serviceable parts. Refer all maintenance to qualiﬁed Yamaha service personnel. Opening the case and/or tampering with the internal circuitry voids the warranty.

5. Always power off before making connections

Always turn the power OFF before connecting or disconnecting cables. This is important to prevent damage to the unit itself as well as other connected equipment.

6. Handle Cables Carefully

Always plug and unplug cables — including the AC power cord — by gripping the connector, not the cord.

7. Clean With a Soft Dry Cloth

Never use solvents such as benzine or thinner to clean the unit. Wipe clean with a soft, dry cloth.

8. Always Use the Correct Power Supply

Make sure that the power supply voltage speciﬁed on the rear panel matches your local AC mains supply. Also make sure that the AC mains supply can deliver more than enough current to handle all equipment used in your system.

Input modules

A/B switch

This switch selects the signal source of the input module. Select INPUT A (XLR type) or INPUT B (1/4” phone type).

2

20dB pad switch

This is a 20dB input pad (attenuator) that affects INPUT A and INPUT B. If the level of the input signal is too high for adjustments to be made using

the GAIN control alone, use the pad to attenuate the signal to an appropriate level. The pad is on when this switch is pressed in.

3

GAIN control

This controls the gain of the preamp for INPUT A and INPUT B. Gain is variable to a maximum of 44dB.

The GAIN control is always used in conjunction with the SIGNAL indicator and the PEAK indicator. Adjust the GAIN control so that the SIGNAL indicator is always lit when an input signal is present, and the PEAK indicator lights occasionally. If the PEAK indicator lights frequently, lower the GAIN control to prevent the signal from distorting.The following table shows usual settings for the GAIN control.

high pass ﬁlter switch

80

This switch cuts the input signal below 80 Hz at 12dB/octave. The ﬁlter is turned on when the switch is pressed in.

By using the high pass ﬁlter, you can reduce or eliminate wind noise, mic pop noise, and power supply hum etc.

6

EQ controls (HIGH, MID FREQ, MID, LOW)

This is a 3-band equalizer with center frequencies, range, and type as shown below.

HIGH: 12 kHz +/–15dB shelving type MID: 250 Hz ~ 5 kHz (variable) +/–15dB peaking type LOW: 80 Hz +/–15dB shelving type The frequency response is ﬂat when the knob is in the center position.

3

EQ switch

This switch turns the EQ on/off. When the switch is pressed in the EQ is on. In addition to bypassing the EQ when it is not being used, this switch provides a convenient way to compare the equalized and unequalized signals.

7

AUX 1 / AUX 2 controls

These adjust the signal level that is sent to each output AUX SEND 1 and AUX SEND 2. These signals are pre-fader (i.e., they are taken from before the fader adjustment). Nominal level is at 3 o’clock position.

AUX 3 / AUX 4 / AUX 5 controls

8

These adjust the signal level that is sent to each output AUX SEND 3, AUX SEND 4 and AUX SEND 5.

The signals controlled by AUX 3 and AUX 4 will depend on the setting of the PRE switch.

• When the PRE switch is not pressed They control the post-fader signal.

• When the PRE switch is pressed They control the pre-fader signal.

AUX 5 controls the post-fader signal. Nominal level is at 3 o’clock position.

C

PFL switch

PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor

the signal of the input module regardless of the fader position, the settings of the ON switch, the group assign switches, or the AUX settings. As the name suggests, the signal is taken pre-fader (post EQ). You may listen to an individual module, or to two or more modules simultaneously. The PFL indicator located at the top of the STEREO module will light when a PFL switch is on.

C

Fader

This adjusts the signal level that is sent to the various outputs. Faders are

∞

used individually or in conjunction with the faders of the other input modules to create the desired mix balance. A position at the zero (0) marking is the nominal level. Raising the fader above 0 provides up to 10dB of gain.

These switches assign the signal of the stereo module to the group outputs and the ST output. The PAN control located below adjusts the stereo position of the signal between the odd (ODD) group and left (L) outputs and the even (EVEN) group and right (R) outputs.

7

BAL/PAN control

The BAL/PAN knob adjusts the balance or the L/R position of the stereo module signal. For example if this knob is turned all the way to the left, the signal will be sent only to the L and odd (ODD) groups whose assign switches are pressed. If it is turned all the way to the right, the signal will be sent only to the R and even (EVEN) groups. If the knob is set to the center position, the same amount of signal will be sent to the stereo L and R, and the odd/even groups.

8

LEVEL control

This adjusts the output level of the stereo module.

ON switch

This switch turns the stereo module on/off. When the switch is pressed the stereo module is on. Be sure to turn off input modules that are not in use. Even when a module is off, the SIGNAL and PEAK indicators will light if a signal is being input. You can also use the PFL switch to monitor the signal even if a module is off.

PFL switch

PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor the signal of the stereo module regardless of the fader position, the settings of the ON switch, the group assign switches, or the AUX settings. As the name suggests, the signal is taken pre-fader (post EQ). You may listen to an individual module, or to two or more modules simultaneously.

La section master offre les caractéristiques suivantes:

• Cinq commandes AUX SEND de type curseur

• Indicateur indépendant à trois points pour chaque commande AUX SEND

• Commutateur TO ST et commande Pan pour chaque GROUP.

• Commutateur GROUP ON, commutateur AFL et curseur 100mm pour chaque GROUP

• L e commutateur MONI/ST2 permet de commuter le signal de sortie ST2/MONI OUT de deux façons:

1) Un des signaux d’une source externe entre par le bus stéréo, le bus PFL ou

le bus 2TR IN.

2) Le même signal comme signal de sortie STI1 OUT.

• Un commutateur ON, L+R , et un curseur contrôlent le signal de sortie ST2/MONI OUT.

Vous trouverez en outre les fonctions suivantes:

• Entrées XLR pour micro

Modules d’entrée

1

Commutateur A/B

Ce commutateur sélectionne la source de signal du module d’entrée. Sélectionne INPUT A (type XLR) ou INPUT B (type jack 1/4).

2

Commutateur d’atténuation 20dB

Il s’agit d’un atténuateur d’entrée de 20dB qui affecte INPUT A et INPUT B. Si le niveau du signal d’entrée est trop haut pour effectuer des réglages au

moyen de la commande GAIN uniquement, utilisez le commutateur d’atténuation pour ramener le signal à un niveau adéquat. L’atténuation est activée lorsque le commutateur est enfoncé.

3

Commande GAIN

Cette commande contrôle le gain du préampli pour INPUT A et INPUT B. Le gain est variable jusqu’à un maximum de 44dB.

La commande GAIN s’utilise toujours en conjonction avec le témoin SIGNAL et le témoin PEAK. Réglez la commande GAIN de sorte à ce que le témoin SIGNAL soit toujours allumé lorsqu’un signal est présent à l’entrée et que le témoin PEAK s’allume sporadiquement. Si ce dernier témoin s’allume souvent, diminuez le GAIN pour éviter toute distorsion du signal. Le tableau suivant vous données les réglages habituels pour la commande GAIN.

Lorsque le niveau du signal après égalisation (niveau nominal 0dB) atteint –10dB, le témoin SIGNAL s’allume. Ce témoin indique qu’un signal entre.

Lorsque le niveau du signal après égalisation atteint 3dB avant le niveau de saturation, le témoin PEAK s’allume pour indiquer que le signal s’approche du niveau de saturation. Réglez donc le niveau du signal en fonction du statut du témoin PEAK. Pour la procédure, voyez l’explication donnée pour la
