User manual YAMAHA EM-120

[. . . ] 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 ST OUT fader (K) below the level that the indicator flashes only briefly on the highest transient peaks. 1+ 1­ 2+ 2­ A+ A­ B+ B­ Jacks 2 are 1/4"phone jacks. The setting of the control panel power amp select switch Y will determine the signal that is output to these jacks, and the number and appropriate impedance of the speakers that can be connected. P. 15 P. 33 Other indicators and controls ^ Level Meter This LED display shows the level of signals received at the ST OUT jack (input/output panel 0). ` Block/Level Diagram PA SPEAKERS OUT MAXIMUM OUTPUT [500W/4] NOMINAL OUTPUT [100W/4] +30dB +20dB +11dB +4dB +10dB 0dB Note: The SPEAKERS 1 & 2 jacks (rear panel 3) output the signals received at the ST OUT jack via the internal power amplifier. Check the output signal level via the LIMITER indicator (X). [. . . ] The signal of the EFFECT 1, 2 buses is sent to the EFFECT SEND 1, 2 jack (input/output panel 9). It is also sent to the built-in effect when the ON switch S in the digital effect section is turned on. Note: The amount of signal that is sent to the EFFECT 1, 2 bus from each channel will be affected not only by the setting of the EFFECT 1, 2 control, but also by the setting of the channel fader C (post-fader send). D PHANTOM indicator This will light when the PHANTOM switch (input/output panel 3) is on. D s Stereo sub input section In this section, you can adjust the input level of external equipment connected to the ST SUB IN 1, 2 jacks on the input/output panel. 7 PAN (panpot) control (EMX5000-20: Channels 1­16, EMX5000-12: Channels 1­8) The PAN knobs set the stereo position of the signal that is sent to the STEREO bus. The signal is located in the center when the knob is positioned at "w, " at right at R, and at left at L. E E 8 BAL (balance) control (EMX5000-20: Channels 17/18­19/20, EMX5000-12: Channels 9/10­11/12) The BAL knobs set the balance between the left and right channels, and assign the signals received at inputs 17/18­19/20, 9/10­11/12 to the STEREO bus. F G F G 9 ON switch, indicator This is an on/off switch for the input signal of each channel. The indicator will light if this switch is turned on. 0 PEAK indicator The indicator will light 3 dB before clipping, warning that clipping level is near. E AUX 1, 2 controls This knob adjusts the amount of the signal sent from the ST SUB IN 1 and 2 jacks (input/output panel 7) to the AUX 1, 2 buses. A SIGNAL indicator This indicator will light if a signal is being input to the corresponding channel. F ST (stereo) control The ST knob adjusts the amount of stereo signal sent from the ST SUB IN 1 and 2 jacks to the STEREO bus. EMX5000-20/EMX5000-12--Owner's Manual 12 Front and rear panel G PFL (pre-fader listen) switch When this switch is turned on, the signal at the point before the ST control knob F is sent to the PHONES jack (input/output panel D). Note: The ST control setting does not affect the level of the signal sent to the PFL/AFL buses (pre-fader send). If the Power amp select switch Y is set to AUX 1MONO, this fader also adjusts the level of the signal sent from the SPEAKERS B 1/2 jacks to the speakers. If the Power amp select switch Y is set to MONO BRIDGE, this fader adjusts the level of the signal sent from the SPEAKERS A 1 jacks to the speaker. K ST OUT fader s Master control section In this section, you can adjust the final level of the outputs. The ST OUT fader adjusts the final level of the signal sent from the STEREO bus to the ST OUT jacks (input/output panel 0). If the Power amp select switch Y is set to ST L-R, this fader also adjusts the level of the signal sent to the SPEAKERS jacks (rear panel 3). Note: The setting of this fader does not affect the signal output from the STEREO bus to the ST SUB OUT jacks. L L AFL (after fader listen) switch When this switch is on, the output signal that passes through the corresponding fader is sent to the PHONES jack (input/output panel D). Use these switches when you wish to monitor a particular output signal through the headphones. s 2TR IN section In this section, you can adjust the input level of a cassette deck or a CD player that is connected to the 2TR IN jacks (input/output panel 5). H I J K H AUX 1 fader The AUX 1 fader adjusts the final level of the signal sent from the AUX 1 bus to the AUX SEND 1 jack (input/output panel 8). If the Power amp select switch Y is set to AUX 1-MONO, using this fader enables you to adjust the level of the signal sent from the SPEAKERS A 1/2 jacks to the speakers. M N M ST (stereo) control This knob adjusts the level of the signal sent from the 2TR IN jacks to the STEREO bus. I AUX 2 fader The AUX 2 fader adjusts the final level of the signal output from the AUX 2 bus to the AUX SEND 2 jack (input/output panel 8). The indicator will blink when this switch is on. a PHONES control This knob adjusts the level of the signal monitored via the PHONES jack (input/output panel D). b ST SUB OUT control This knob adjusts the final level of the signal sent from the STEREO bus to the ST SUB OUT jacks (input/output panel A). Note: The setting of this control does not affect signals that are sent from the STEREO bus to the ST SUB OUT jacks and the SPEAKERS jacks. ] c LPF control, ON/OFF switch This switch applies a low-pass filter to the signal that is output from the PFL/AFL bus to the MONO OUT jack. The frequency is indicated by the position of the slit in the control trimmer that is set into the panel above the switch. To adjust the frequency, use a slotted screwdriver to turn the control to the desired position. This will output the region below the frequency (80­120 Hz) you specify by the control knob. Use this when you are using a sub-woofer. EMX5000-20/EMX5000-12--Owner's Manual 16 Front and rear panel Input/output panel 1 3 4 56 8 0 A E FG 2 1 Channel input jacks (INPUT A, INPUT B) EMX5000-20: 1­16, EMX5000-12: 1­8 By using the GAIN control (control panel 2) you can connect any of the jacks to a wide range of sources, from mics to line-level devices (including synthesizers and rhythm machines). The INPUT A jacks can provide +48V phantom power, allowing you to use condenser microphones. The nominal input level is from ­16 dB to ­60 dB when the 26 dB pad switch (control panel 1) is off, or from +10 dB to ­34 dB when it is on. They are compatible with microphones of output impedance 50­600 or line level devices of 600. Pin connections for the jacks are as follows: INPUT A jacks (XLR type) INPUT B jacks (TRS phone jacks) * 7 9 B DC Note: It is not possible to simultaneously use both the INPUT A and B inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source. [. . . ] Use a speaker with an impedance of 4-8 ohms.
