This graphic equalizer affects both the MAIN bus signal that is output to the speakers and the line level signal which is output from the MAIN jack (input/output panel 6). D EFFECT RTN control This adjusts the level of the effect signal which is returned from the built-in digital effect to the MAIN bus. E AUX IN control This adjusts the amount of signal that is sent from the AUX IN jack to the MAIN bus. F TAPE IN This adjusts the amount of signal that is sent from the TAPE IN jacks to the MAIN bus. G MASTER control This adjusts the final level of the MAIN bus. It affects both the MAIN bus signal which is output from the speakers, and the line level signal which is output from the MAIN 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 MAIN 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 output from the built-in two-channel power amplifier, and to select the BRIDGE mode. 2AMPs 300W 300W 1 2 LIMITER I MAIN BRIDGE MAIN MAIN MAIN MONITOR J POWER AMP 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 specify the signals that will be output from power amp 1/2. • MAIN BRIDGE With this setting, the MAIN bus signal will be output from the BRIDGE jack. The two power amp channels (A and B) will be bridge connected. Only the MASTER control G in the MAIN section becomes effective. • MAIN-MAIN With this setting, the MAIN bus signal will be output from the POWER AMP 1 A/B jacks and from the POWER AMP 2 A/B jacks. Only the MASTER control G in the MAIN section becomes effective. • MAIN-MONITOR With this setting, the MAIN bus signal will be output from the POWER AMP 1 A/B jacks and the MONITOR bus signal is output from the POWER AMP 2 A/B jacks. Only the MASTER controls in the MAIN and MONITOR sections G, A are both effective. EMX660-Owner's Manual
