To take the best advantage of your mixer, we recommend careful reading of this Instruction Manual . . .even if you already have a good general understanding of mixers. The setups on the following pages are meant only as guidelines. We have attempted to cover many applications. It would be impossible to cover all conceivable setups, which are infinite as your own imagination. SECTION ONE Brief Operating Instructions NOTE: Be sure the AC POWER switch is turned OFF when making all signal and speaker connections. EMX150 Front Panel EMX200 Front Panel (K) ©(Q)(R) (Q) (£)©(9)(r) (§) FRONT PANEL A. Pad switch. Gain control, & LED peak indicator The Pad and Gain control adjust the input sensitivity of the EMX mixers over a wide range. The PAD switch inserts a 20 dB pad ahead of the preamplifier, and the GAIN control continuously adjusts the sensitivity of the preamplifier between —20 and —60 dB. The adjacent LED turns on to warn of impending distortion when the GAIN control level is 3 dB below clipping. B. High, Mid/Frequency and Low EQ controls These continuously variable knobs allow ±15 dB equalization in the following frequency ranges: HIGH................8 kHz shelving. MID.................0.35-5 kHz sweepable peaking. LOW................100 Hz shelving. Response is flat at center position. E MX 300 Front Panel C. FBI and FB2 send controls These controls feed a post-EQ, pre-fader signal to the FB1 and FB2 busses which feed the FB1 and FB2 outputs, respectively. These foldback sends may be used for stage monitoring, additional effects mixes, or mono or stereo recording mixes. D. Echo control Adjusts the amount of post EQ, post-fader signal fed from the channel to the internal analog delay (echo) unit or an external echo, reverb, or effects device. E. Pan control This knob feeds the input channel signal to the left and right stereo program mixing busses. The stereo program buss then feeds the SPEAKER, LINE and HEADPHONE outputs via the master program faders. F. Channel Fader These set the mix level of each channel. These smooth linear faders also provide a good'visual indication of the overall mix levels. G. VU Meters Two meters on the EMX150 indicate average speaker power output level. On the EMX200 and EMX300 an additional pair of meters indicate the average output level of the two F.B mix busses. The meters are illuminated when AC power is ON. H. EQ In/Out Switch This switch by passes the channel equalizer for A-B comparisons during setup; quick changes in sound, and for the clearest, quietest sound when EQ is not needed. I. Graphic Equalizer Two banks of linear slide controls independently vary the frequency response of the left and right program outputs. There are nine GEQ controls per channel. Center detents mark the flat position (no EQ effect) for each control. J. FB1 and FB2 Controls These controls apply signals from the AUX inputs to the respective FB busses. K. Aux Pan These controls position the AUX 1 and AUX 2 input signals left-to-right on the stereo program buss. L. Aux Volume These controls set the level of any program fed to the mixer via the AUX 1 and AUX 2 input jacks. Following these controls, the AUX inputs are also affected by the master program faders. M. Delay Time Adjusts the delay time of the internal analog delay unit. If this control is adjusted while the delay is in use, pitch changes may occur during the time the control is actually being moved. N. Feedback Adjusts the amount of feedback applied to the internal analog delay unit, and therefore the number of "repeats" the delay unit produces. Careful adjustment of Delay Time and Feedback can produce reverb-like effects. O. Echo Return This control sets the level at which the output signal from the internal analog delay unit or from an external echo device is mixed into the stereo program buss. The echo signal is applied equally to the left and right program busses, and is therefore a "center" effects return. If the ECHO RETURN jack is used as an auxiliary mon...
