Parts of the EMX62M owner’s manual have been revised. Please refer to the following revisions rather than the corresponding sections of the original owner’s manual. Révisions du Mode d’emploi de l’EMX62M F Nous vous remercions d’avoir opté pour le mélangeur amplifié EMX62M de Yamaha. Nous avons apporté une série de révisions au Mode d’emploi de l’EMX62M. Nous vous invitons à tenir compte de ces changements dans les sections correspondantes du Mode d’emploi original. P.11 P.10 ■ MAIN section D ■ Section MAIN D C C C Level Meter This LED display shows the level of signals received at the MAIN OUT jack (input/output panel 9). Note: The SPEAKERS 1 & 2 jacks (rear panel 1) output the signals received at the MAIN OUT jack via the internal power amplifier. Check the output signal level via the LIMITER indicator (D). C Indicateur de niveau Cet indicateur à diodes affiche le niveau des signaux reçus par la borne MAIN OUT (tableau des entrées/sorties 9). Remarque: Les bornes SPEAKERS 1 & 2 (face arrière 1) produisent les signaux transmis à la borne MAIN OUT et amplifiés par l’amplificateur de puissance interne. Le témoin LIMITER (D) permet de contrôler le niveau du signal de sortie. D LIMITER indicator If the output level of signals received at the SPEAKERS 1 & 2 jacks (the output of internal power amplifier) reaches maximum, the indicator will light. Caution: If the LIMITER indicator flashes continuously, the internal power amplifier section is being excessively overloaded and may malfunction. Reduce the output level at the MASTER control (B) below the level that the indicator flashes only briefly on the highest transient peaks. D Témoin LIMITER Ce témoin s’allume lorsque le niveau du signal reçu aux bornes SPEAKERS 1 & 2 (et transmis par l’amplificateur de puissance) atteint la valeur maximale. Attention: Si le témoin LIMITER clignote de façon permanente, l’amplificateur de puissance interne est saturé et pourrait présenter un dysfonctionnement. Dans ce cas, réduisez le niveau de sortie avec la commande Master (B), de sorte que le témoin ne clignote plus que brièvement aux pics de niveau.

The MONITOR control is not affected by the channel’s LEVEL control 4, since the MONITOR signal is sourced before that control. C EFFECT control 1 2 The EFFECT control determines the level of the input signal that is fed to the EFFECT bus and subsequently the onboard effects processor and EFFECT OUT jack (input/output panel 4). EFFECT bus signals are fed simultaneously to the onboard effects processor and the EFFECT OUT jack for use with external effects processors. The EFFECT bus signals are affected by the channel’s LEVEL control 4, since the EFFECT signal is sourced after the EFFECT control. To send a channel signal to the EFFECT bus, both the EFFECT and LEVEL controls must be turned up. D LEVEL control 3 4 5 1 HIGH & LOW EQ controls The 2-band equalizer allows you to boost or cut the low or high frequency range for each channel. The frequency response is flat when the controls are in the center (▼) position. Rotating clockwise boosts frequencies, rotating counterclockwise cuts them. The center frequencies are as follows: HIGH: 10 kHz ±15 dB shelving type LOW: 100 Hz ±15 dB shelving type The LEVEL control determines the level of the input signal that is fed to the MAIN bus and internal power amplifier. The MAIN bus signal is routed to the MAIN OUTPUT jack (input/output panel 9), SPEAKERS 1 and 2 jacks (rear panel 1), and PHONES jack (input/output panel A). E PAD switch (1–4 only) The PAD switch attenuates the input signal by 30 dB. When connecting a line-level source to inputs 1 through 4, or if a microphone signal is distorted, use the PAD switch to attenuate the input signal. B MONITOR control The MONITOR control determines the level of the input signal that is fed to the MONITOR bus and subsequently the MONITOR OUTPUT jack (input/output panel 0).

C Use the MONITOR MASTER control to set Note: When connecting line-level sources to input channels 1 through 4, turn on the corresponding PAD switch. The Low-Z and Hi-Z jacks on input channels 1 through 4 cannot be used simultaneously. The EMX62M features a built-in digital effects processor, allowing reverberation or ambiance to be added to vocals or instrument sounds. B Turn on the power, starting with the sound sources and finishing with the EMX62M. Reverse this order when turning off the power. √” C Set the MAIN MASTER control to the “√ position. D While speaking into a connected mic, or playing a connected instrument, adjust the input channel LEVEL control so that the 0 LED of the MAIN section level meter lights occasionally. Repeat this procedure for each channel. E Use the EQ controls on each input channel to adjust the tonal characteristics of each source. F Use the 7-band graphic equalizer to adjust the tonal characteristics of the main output. G Use the MAIN MASTER control to set the overall volume level of the main mix. Monitoring By connecting a powered monitor speaker to the MONITOR OUTPUT, you can create a monitor mix independent of the MAIN mix, since the EMX62M—Owner’s Manual the overall level of the monitor mix. Using the Built-in Effects 1 Turn on the digital effects processor by pressing the DIGITAL EFFECT ON switch. The DIGITAL EFFECT indicator lights up. B Use the DIGITAL EFFECT switches to select an effects program. VOCAL REVERB....... Reverb suitable for vocals. LARGE HALL ............ Reverb typical of a large hall. SMALL HALL ............ Reverb typical of a small hall. C Set the MAIN EFFECT RTN control to the √” position. “√ D While speaking into a connected mic, or playing a connected instrument, adjust the EFFECT control of the input channel that you want to process. E Use the MAIN EFFECT RTN control to adjust the overall level of the processed sound. F Use the MONITOR EFFECT RTN control to feed the processed signal to the MONITOR bus and subsequently MONITOR OUTPUT. Note: If the processed sound is distorted even with an EFFECT RTN control turned down, turn down the EFFECT control on each channel.  Installing an optional rack mount kit 17 Installing an optional rack mount kit You can rack-mount the EMX62M using an optional rack mount kit (RK-88). Rack mount kit RK-88 Installing the rack mount bracket 1 Remove the carrying handle by loosening and removing four screws. • Bracket × 2 • Screw × 6 Before you rack-mount the EMX62M, make sure that sufficient ventilation will be maintained. (Never install the unit in a sealed rack.) If you are going to install multiple devices including the unit in a rack, keep a 1U space or more between the devices. Use a blank panel with holes for ventilation if you wish to insert a panel between the devices. You will need a 7U space to install the rack mount. After installation, the unit will project 62 mm from the front surface of the rack. 2 Attach one of the rack mount brackets to the side of the EMX62M using three included screws. 62 3 Attach the other rack mount bracket in the same way. EMX62M—Owner’s Manual  18 Troubleshooting Troubleshooting The following table describes the possible malfunctions of this demvice, and the appropriate actions to be taken in each case. Problem The POWER indicator is lit. Sound is no longer output from the speakers. Cause Action The load on the amplifier of this device was too great, and the protection circuit for the amplifier has operated. Possible reasons for the excessive load are an excessive level setting in the channel control section or main section, insufficient ventilation, or insufficient load impedance of the connected speakers. Please wait. When the device cools off, normal operation will resume automatically. However, please check the following three points to prevent the problem from recurring. • If the level setting is excessive, lower it to the nominal level. You can refer to the peak level indicators of the main section when doing so. • If the device is not ventilated sufficiently, refer to the cautions given at the beginning of this manual and take appropriate measures to insure adequate ventilation. • If the load impedance (including a short) is too low, refer to the section on rear panel (page 14) and change the connections so that the impedance is correct. Connections between devices have come loose. Inspect the connections, and correct any faulty connections. Other The device may have malfunctioned. Please contact your dealer. Other Unbalanced sound output from the speakers The speaker’s protection circuit has Turn off the power to the EMX62M, or lower the volume been activated due to excessive input level. The EMX62M will return to its normal operation in No high range several seconds. Then, turn on the power to the unit or signals. is heard from raise the volume level and check to see if the high range is the speakers. audible. Maintain the level so that the protection circuit will not be activated. Powered Mixer Q&A Q: The built-in effect is not effective. A: The ON switch in the DIGITAL EFFECT section may not be turned on. Or, you have adjusted the EFFECT control in the Channel section or the MAIN EFFECT RTN control. Q: The monitoring sound from the speakers is not powerful enough relative to the level of the input sound. Q: The stereo output from the synthesizer has been routed to the Super Hi-Z jack of channel 6, but the monitoring sound is not stereo. Q: The signal is sent from the EFFECT OUT jack to the connected effect processor. Then the effect sound is returned to the AUX IN jack. However, no signal is input to the mixer. Q: An external powered speaker is connected to the MONITOR-OUTPUT jack. However, the signal is not sent to the speaker even when the MASTER control in the MONITOR section is turned. Q: Can the Low-Z jack and the Hi-Z jack be used at the same time? Q: Can a single speaker be connected to the mixer? EMX62M—Owner’s Manual A: The equalizer LOW control for each channel may be set to negative values. A: You can use Super Hi-Z (or LINE) 1 and 2 jacks at the same time. However, they are internally routed into a mono channel, and therefore the signals from 1 and 2 jacks are output as mono signal. A: The AUX IN control in the MAIN section may not be rotated to right. A: The MONITOR controls for input channels may not have been adjusted. A: You cannot use the Low-Z jack and the Hi-Z jack for the same channel at the same time. A: Yes. Use a speaker with an impedance of 4-8 ohms.  Specifications 19 Specifications ■ General Specifications Maximum output power 135 W/8Ω @0.5% THD at 1 kHz (SPEAKERS OUT) 200 W/4Ω @0.5% THD at 1 kHz (SPEAKERS OUT) 175 mW/40Ω @0.5% THD at 1 kHz (PHONES OUT) Frequency response 20 Hz–20 kHz +1 dB, –3 dB @1 W output into 8Ω (SPEAKERS OUT) 20 Hz–20 kHz +1 dB, –3 dB @+4 dB output into 10 kΩ (MAIN OUT, MONITOR OUT, EFFECT OUT) Total harmonic distortion Less than 0.5% @20 Hz–20 kHz, 100 W output into 4Ω (SPEAKERS OUT) Less than 0.3% @20 Hz–20 kHz, +14 dB output into 10 kΩ (MAIN OUT, MONITOR OUT, EFFECT OUT) –124 dB equivalent input noise, –68 dB residual output noise (SPEAKERS OUT) –88 dB residual output noise (MAIN OUT, MONITOR OUT) Hum & noise (Average, Rs=150Ω) (with 20 Hz–20 kHz BPF) –79dB (83 dB S/N) (MAIN OUT, MONITOR OUT) Master level control: nominal level Channel level controls: minimum –69 dB (73 dB S/N) (MAIN OUT, MONITOR OUT) Master level control: nominal level 1 channel level control: nominal level –75 dB (79 dB S/N) (EFFECT OUT) All channel level controls: minimum –69 dB (73 dB S/N) (EFFECT OUT) 1 channel level control: nominal level Maximum voltage gain 86 dB CH IN (Lo-Z) to SPEAKERS OUT (CH1–4) 66 dB CH IN (Lo-Z) to MAIN OUT, MONITOR OUT (CH1–4) 66 dB CH IN (Lo-Z) to EFFECT OUT (CH1–4) 48 dB CH IN (Lo-Z) to REC OUT (CH1–4) 56 dB CH IN (Hi-Z) to MAIN OUT, MONITOR OUT (CH1–4) 26 dB LINE IN to MAIN OUT (CH5) 26 dB AUX IN to MAIN OUT 22 dB 2TR IN to MAIN OUT 46 dB Super Hi-z IN to MAIN OUT (CH6) Crosstalk at 1 kHz 65 dB adjacent input, 65 dB input to output Input channel equalization ±15 dB Maximum HIGH 10 kHz shelving * LOW 100 Hz shelving * * Turn over/roll-off frequency of shelving: 3 dB below maximum variable level.
