10 Front and rear panel Front and rear panel Control panel s Channel control section In this section, you can adjust equalization (frequency response), volume level, effect and AUX output levels for the input signal of each channel. 1 2* 2 3 4 4 5 5 6 6 7 8 9 9 0 0 A A B B C C 1 26 dB pad switch This switch attenuates the input signal by 26 dB. Attenuation is on when the switch is pressed inward. 2 GAIN control Use this knob to adjust the sensitivity according to the input signal level, so that the input level is appropriate. For the best balance of S/N ratio and dynamic range, adjust this knob so that the peak indicator 0 lights occasionally. * When the knob is at the " " position, the input sensitivity will be +4 dB. 3 (High pass filter) switch This is an on/off switch for the high-pass filter. The high-pass filter is on when the switch is pressed inward, and the frequency region below 80 Hz will be attenuated at 18 dB/octave. 4 Equalizer controls (HIGH, MID, LOW) This is a 3-band equalizer that adjusts the high frequency range, mid frequency range, and low frequency range of each channel. When the HIGH and LOW knobs are in the "w" position, the high and low ranges will have a flat response. Turning a knob toward the right will boost the corresponding frequency range, and turning it toward the left will cut it. For the mid range, use the upper MID knob to specify the center frequency of the range, and use the lower knob to set the amount of boost or cut that will occur. The frequency response is flat when the lower knob is set to the "w" position. Turning the lower knob toward the right will boost the corresponding frequency range, and turning the knob toward the left will cut it. The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows: HIGH: 10kHz, ±15 dB, shelving type MID: 250Hz-5kHz, ±15 dB, peaking type LOW: 100Hz, ±15 dB, shelving type EMX5000-20/EMX5000-12-Owner's Manual
