EMX620—Owner’s Manual  6 Front & Rear Panels Front & Rear Panels Control Panel ■ Channel Section The channel controls are used to set the EQ, MONI and EFFECT send levels, channel LEVEL, and PAD for each channel. 1 HIGH 1 –15 +15 LOW –15 +15 MONI 2 0 EFFECT 10 0 LEVEL 10 0 10 4 PAD 1 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 B MONI control The MONI control determines the level of the input signal that is fed to the MONI bus and subsequently the MONITOR OUTPUT jack. The MONI control is not affected by the channel’s LEVEL control, since the MONI signal is sourced before that control. EMX620—Owner’s Manual 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. EFFECT bus signals are fed simultaneously to the onboard effects processor and the EFFECT OUT jack for use with external effects processors. The EFFECT control is affected by the channel’s LEVEL control, since the EFFECT signal is sourced after that control. To send a channel signal to the EFFECT bus, both the EFFECT and LEVEL controls must be turned up. D LEVEL control 3 5 C EFFECT control The LEVEL control determines the level of the input signal that is fed to the MAIN bus, MAIN output section, and internal power amplifier. 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.  7 Control Panel ■ DIGITAL EFFECT Section ■ MAIN Section The DIGITAL EFFECT section is used to turn the built-in digital effects processor on and off and select effects programs. The MAIN section is used to set the MAIN MASTER level, 7-band graphic equalizer, AUX IN and TAPE IN levels, and MAIN EFFECT RTN level. It also contains the LIMITER indicator and main output level meter.

G DIGITAL EFFECT ON switch & indicator The DIGITAL EFFECT ON switch is used to turn the built-in digital effects processor on and off. The indicator lights up when the processor is on. When the processor is on, its output is fed to the MAIN and MONI buses via the MAIN EFFECT RTN and MONI EFFECT RTN controls respectively. The effects processor can also be turned on and off remotely by connecting an optional footswitch to the FOOT SW jack. 9 0 H Graphic equalizer The 7-band graphic equalizer is used to boost or cut certain frequencies of the MAIN output signal by up to ±12 dB. It affects the MAIN OUTPUT signal, the speaker outputs, and the PHONES. I EFFECT RTN control The MAIN EFFECT RTN control determines the level of the signal from the built-in digital effects processor that is fed to the MAIN bus and subsequently the MAIN outputs. J AUX IN control The AUX IN control determines the level of the AUX IN signal that is fed to the MAIN bus and subsequently the MAIN outputs. K TAPE IN The TAPE IN control determines the level of the TAPE IN signal that is fed to the MAIN bus and subsequently the MAIN outputs. L MASTER control The MAIN MASTER control determines the output level of the MAIN OUT, speaker outputs, and PHONES. M Level meter The 5-LED meter displays the level of the MAIN output signal. EMX620—Owner’s Manual  8 Front & Rear Panels N LIMITER indicator The LIMITER indicator lights up when the limiter circuit, which is designed to protect the internal power amplifier against excessive input signals and load mismatches, activates. If the LIMITER indicator lights up, back off the MAIN MASTER level control, or the appropriate channel LEVEL control a little. If the indicator remains lit, make sure that the impedance of the connected speaker system is correct. The MONI section is used to set the MONI MASTER level and MONI EFFECT RTN level. E 10 EFFECT RTN F 0 10 MASTER MONI O EFFECT RTN The MONI EFFECT RTN control determines the level of the signal from the built-in digital effects processor that is fed to the MONI bus and subsequently the MONITOR OUTPUT.
