FRONT PANEL

1. EQ Bands – Use these sliders to boost or cut the level of each audio frequency band. When all the sliders are

in the center position, the equalizer outputs a flat frequency response.

2. Input Level Meter – Displays the level of the incoming signal. The "0 dB" position is unity gain (no boost or

attenuation). If the clip LED lights continuously, turn down this control.

3. SIG CLIP – Flashes red when the input or output signal gets within 5 dB of clipping. If this occurs, turn down

the input or output signal to avoid distortion.

4. Range – Selects which of the two boost/cut ranges the EQ band sliders will use, either ±6 dB or ±15 dB.

WARNING: Adjusting this switch generates a loud transient. Before changing the setting of the switch, reduce

the audio level of your power amplifier.

5. Hi Pass – Reduces the low frequencies from the signal.

6. Low Pass – Reduces the high frequencies from the signal.

7. EQ On – Select to bypass the EQ and hear the unprocessed signal.

5. 1/4” and XLR Outputs – Connect these outputs to a mixer’s Aux Return or powered speakers.
