Front and rear panel 11 s MONITOR section This section allows you to adjust the tone and volume of the MONITOR bus, and specify the mix level of the built-in effect and the external input signals. D +12 6 0 6 -12 +12 +6 6 +3 0 0 6 -5 -12 -10 125 250 500 1k 2k 4k 8k GEQ E 0 10 EFFECT RTN F 0 10 2TR IN MONITOR 0 10 MASTER H G D Graphic equalizer This is a 7-band graphic equalizer that allows you to adjust the frequency response of the MONITOR bus signal, providing a maximum of ±12 dB of cut/boost for each frequency band. You can use these sliders to reduce the level of frequency bands at which feedback easily occurs. Frequency response is flat when a slider is in the center position. Moving a slider in the positive direction will boost, and in the negative direction will cut. This graphic equalizer affects both the MONITOR bus signal that is output to the speakers and the line level signal which is output from the MONITOR jack (input/output panel 6). E EFFECT RTN control This controls the level of the effect sound which is returned from the built-in digital effect to the MONITOR bus. F 2TR IN control This controls the level of the signal routed from the 2TR IN jack (input/output panel 5) to the MONITOR bus. G MASTER control This adjusts the final level of the MONITOR bus. It affects both the MONITOR bus signal which is output to the speakers and the line level signal which is output to the MONITOR jack (input/ output panel 6). H Peak level indicator This indicator allows you to monitor the level of the signal which is output from the MONITOR jack (input/output panel 6). Note: To avoid distortion, adjust the MASTER control (G) so that the 0 indicator lights occasionally. s POWER AMP section This section allows you to select the signals that will be input to the built-in two-channel power amplifier. POWER AMP I LIMITER J MAIN MAIN MON MAIN MAIN BRIDGE A B I LIMITER indicator This indicator lights up when the level of the signal output from the power amp section reaches the maximum and the limiter is activated. Adjust appropriate control so that the indicator lights up for only a short while when the signal reaches the maximum level. Note: The indicator lights up or flashes for a longer duration if the power amp section is significantly overloaded, which could result in malfunction. Avoid such a situation. J Power amp select switch Select one of the following three settings to route the signals to the appropriate jacks, depending on the speaker connection at the SPEAKERS jacks (rear panel 1). • MAIN-MON With this setting, the MAIN bus signal will be output from the SPEAKERS A 1/2 jacks and the MONITOR bus signal is output from the SPEAKERS B 1/2 jacks. The MASTER controls (B, G) in the MAIN and MONITOR sections are both effective. • MAIN-MAIN With this setting, the MAIN bus signal will be output from the SPEAKERS A 1/2 jacks and from the SPEAKERS B 1/2 jacks. Only the MASTER control B in the MAIN section becomes effective. • MAIN BRIDGE With this setting, the MAIN bus signal will be output from the BRIDGE jack. The two power amp channels will be bridge connected. Only the MASTER control B in the MAIN section becomes effective. EMX66M-Owner's Manual
