Resumen del manual
Truth in slider position became a requirement. The curve traced out by the slider positions on Constant-Q designs indeed represent the actual change to the frequency response. On conventional designs they do not. Only for EQA131 and EQA 231 FRONT AND REAR PANELS 4 FRONT AND REAR PANELS EQA215 EQA131 1. Power Switch 2. Filter Level Controls 3.

Power Switch This switch is pressed to turn power ON, pressing the switch again turns the power off. Always turn on your equalizer BEFORE your power amplifiers are turned on, and always turn off equalizer AFTER your power amplifiers have been turned off. 2. Filter Level Controls Each of these sliders control the output level of each of the 31 (or 15) bandpass filters. Center detent position is grounded for guaranteed flat response. 3. Filter Range Switch & Indicators The gain range of the filter sliders is switchable (as a group) from +/-6dB to +/-12dB for maximum boost/cut capability. When this switch is in the "OUT MOST" position, at 6dB, the green LED will illuminate. When it is in the "IN MOST" position, at 12dB, the yellow LED will illuminate. 4. Bypass Switch When it is the "IN MOST" position, equalizer is bypassed. Its associated LED indicates status. (See 8. Bypass indicator) 5. HPF Frequency Control (EQA 231 and EQA131) To cut down unwanted signal, this control determines the roll-off frequency of the High-Pass Filter. The roll-off frequency can be adjusted from 10Hz to 250Hz by turning this knob. Because of its high roll-off slope, the HPF can be efficiently used to cut down the "HUM" from preceding instruments, or to prevent low-frequency resonance. 6. LPF Frequency Control (EQA 231 and EQA131) To cut down unwanted signal this control determines the roll-off frequency of the Low-pass filter. The roll-off frequency can be adjusted from 3KHz to 40KHz by turning the knob. Because of its high roll-off slope, this LPF can be efficiently used to cut down the high- frequency noise from preceding instruments, or especially used to roll-off high-frequency sound to obtain a more natural sound in acoustic situations. 7. Level Control This controls the level of the incoming signal. Turn this control down if the PEAK LED illuminates steadily. Unity gain can be set by turning this knob its center detent position. 8. Bypass Indicator When the green LED is illuminated this indicates that the unit or channel is in the bypass mode. Signal is routed directly from the input to the output without passing through any circuit (often referred to as "hard-wire bypass"). 5 Specifications Equalizer: EQA231 ……………………………1/3-Octave ISO Spacing From 20Hz to 20KHz EQA131 ……………………………1/3-Octave ISO Spacing From 20Hz to 20KHz EQA215 ……………………………2/3-Octave ISO Spacing From 25Hz to 16KHz Type ………………………………Constant Q (Accuracy 5% Center Frequency) Range ……………………………±6dB or ±12dB (Switch Selectable) Inputs: Connectors ………………………XLR 3Pin, 1/4" TRS Impedance ………………………20K Ohms Bal; 15K Ohms Maximum Level …………………+24dBu (Bal) +18dBu (Unbal) Outputs: Connectors ………………………XLR-3Pin, 1/4" TRS Impedance ………………………Typ. <150 Ohms Maximum Level …………………+24dB Bal; +18dB Unbal (2K Ohms) +18dB Bal; +12dB Unbal (600 Ohms) Overall Gain Range ………………Off to 3dB ( Unbal Out ) Sliders Centered Off to 9dB ( Bal Out ) Sliders Centered PEAK LED …………………………Threshold 5dB ( Below Clipping) Frequency Response ……………20~20KHz +0, -2dB HPF Filter …………………………10~...
