4 - BYPASS: When depressed, this switch routes the input signal directly from the BALANCED INPUT jacks (#9) to the BALANCED OUTPUT jacks (#10), bypassing the equalizer controls completely. This is useful when comparing the equalized signal to the original. The adjacent LED (linked graphically to the switch with a solid line) glows red when in the bypass mode. 5 - PEAK LED: This indicator glows red when the input or output signal is within 5dB of clipping. Adjust the LEVEL control (#8) so this LED only flashes during strong, peak-level signals. 6 - LOW CUT: Use this control to set the rolloff frequency for the high pass filter. The filter is continuously variable from 10Hz to 250Hz with a rolloff of 12dB/octave. 7 - HIGH CUT: Use this control to set the rolloff frequency for the low pass filter. The filter is continuously variable from 3kHz to 40kHz with a rolloff of 12dB/octave. 8 - LEVEL: Use this control to adjust the input signal level. For the best signal to noise ratio set this control so the PEAK LED (#5) flashes on strong, peak-level signals. The overall output signal level of the equalizer is determined by the setting of this control and the EQ sliders (#2). 9 - BALANCED INPUTS: The mixing board, amplifier or instrument (“source”) may be connected to the equalizer using either of these jacks. However, only one jack may be used at a time. Different methods of connection are described and illustrated on pages 9 and 10. 10 - BALANCED & UNBALANCED OUTPUTS: The equalizer may be connected to the mixing board or amplifier using either of these jacks. The 1/4” phone jack and the XLR jack are balanced. The RCA jacks are unbalanced. Different methods of connection are described and illustrated on pages 9 and 10. 11 - GROUND LIFT: Use this switch to electronically disconnect the signal ground from the mains and chassis earth ground. This may be helpful in eliminating ground loops which cause hum. 12 - VOLTAGE SELECTOR: The equalizer is designed to be used with either 95-130VAC or 190-250VAC power sources. Check the AC line voltage of the outlet and set this switch accordingly before plugging in the unit. 13 - FUSE HOLDER: This contains the fuse for the AC mains. If the fuse blows, replace it with only the same size and type. If the fuse blows repeatedly, check the AC line voltage and the equalizer’s voltage selector switch. If the problem persists contact your Crate Pro Audio dealer. 14 - POWER CORD: Connect the power cord to a suitable source of AC line voltage. Be sure to match the voltage selector switch (#12) to the line voltage before making this connection! In order to reduce the risk of shock, DO NOT defeat the ground pin of the power cord!

Each slider adjusts the signal ±6dB or ±12dB depending on the setting of the RANGE switch (#3). Moving a slider up boosts the signal; moving it down cuts the signal. The center detent is the “flat” position (no boost or cut). 3 - RANGE: Use this switch to select one of two adjustment ranges for the EQ sliders (#2). With the switch out, the adjustment range is ±12dB. When this switch is depressed, the adjustment range is ±6dB. Care should be taken not to accidentally change the range from 6dB to 12dB during operation if extreme boosts are used, since the boosts will dramatically increase if this occurs. 4 - BYPASS: When depressed, this switch routes the input signal directly from the BALANCED INPUT jacks (#7) to the BALANCED OUTPUT jacks (#8), bypassing the equalizer controls completely.
