User manual YAMAHA CS80E

[. . . ] The input signals for the two channels can be selected as MAIN+MAIN, MAIN+MONITOR, or MAIN (bridge connection). · Independent 7-band graphic EQ is provided for both the MONITOR section and the MAIN section. This allows the volume and frequency response to be adjusted separately for the main speakers and monitor speakers. · Two limiter circuits are built-in to prevent excessive input levels to the amp. [. . . ] In that case, the signal processed by the digital effect will be sent to the MAIN/MONITOR bus. The mix level of the effect sound is adjusted by the EFFECT RTN control of the MAIN and MONITOR sections. EMX640--Owner's Manual 4 Front and rear panel 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. s MAIN section This section allows you to adjust the tone and volume of the MAIN bus, the mix level of the built-in effect, and the mix level of the external input. +12 · 6 · 0 · 6 · ­12 125 250 500 1k 2k 4k 8k +12 · 6 · 0 · 6 · ­12 9 +12 · 6 · 0 · 6 · ­12 125 250 500 1k 2k 4k 8k +12 · 6 · 0 · 6 · ­12 +6 +3 0 ­5 ­10 C B +6 +3 0 ­5 ­10 H G A EFFECT RTN AUX IN TAPE IN MASTER MASTER 0 EFFECT RTN MAIN MONITOR D E F 9 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). C Graphic equalizer This is a 7-band graphic equalizer that allows you to adjust the frequency response of the MAIN bus signal, providing a maximum of ± 12 dB of cut/boost for each frequency band. 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. 0 EFFECT RTN control This controls the level of the effect sound which is returned from the built-in digital effect to the MONITOR 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. A 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). 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). B 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 (A) so that the 0 indicator lights occasionally. 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. EMX640--Owner's Manual Control panel 5 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. s POWER indicator & PHANTOM switch I 1 LIMITER K 2 ON OFF POWER PHANTOM +48V L MAIN BRIDGE MAIN MAIN MAIN MONITOR J POWER AMP K POWER indicator This indicator will light when the power of the EMX640 is turned on. 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. Phantom power is switched on/off in simultaneously for channels 1~6. If the two channels are used independently, two speakers can be connected to the POWER AMP 1 A/B jacks and two more to the POWER AMP 2 A/ B jacks, for a total of four speakers. If the two channels are used in a bridge connection, only one speaker can be connected to the BRIDGE jack. If you wish to use the two channels independently, but only connect a speaker to the A jack or B jack, use a 4~8 speaker. When using the A and B jacks simultaneously, connect 8~16 speakers. In this case, be careful not to connect a speaker to the BRIDGE jack. If you are connecting a speaker to the BRIDGE jack, use a 8~16 speaker. In this case, be careful not to connect a speaker to the POWER AMP 1/2 A/B jacks. Note: Use the power amp select switch (control panel J) to select the signal which is sent to the jacks, or to activate the bridge connection. Caution: When using a bridge connection, do not connect anything to the POWER AMP 1 and POWER AMP 2 jacks. Likewise, when using the POWER AMP 1 and/or POWER AMP 2 jacks, do not connect anything to the BRIDGE jack. 2 Power switch This switch turns the power of the EMX640 on/ off. Note: Before turning the EMX640 on/off, turn down the MASTER controls of the MONITOR and MAIN section. EMX640--Owner's Manual 8 Connections Connections When connecting various devices, be sure to use cables and plugs of the appropriate standard. s Speaker connection There are three ways in which speakers can be connected to the EMX640; a single speaker each can be connected to either the A or the B jack of POWER AMP 1 and of POWER AMP 2, two speakers can be connected in parallel to both the A and B jacks of POWER AMP 1 and of POWER AMP 2, or a single speaker can be connected to the BRIDGE jack (bridge connection).
