Introduction

The Australian Monitor Installation Series AMIS215EQ & AMIS31EQ are single rack unit graphic equalizers. Both equalizers feature constant Q circuitry, selectable 6dB or 12dB slider range, balanced XLR, 6.35mm TRS & unbalanced RCA inputs & outputs, EQ bypass switches, ground lift switches, output level controls & overload LED’s. These features are usually associated with equalizers many times the price of these Australian Monitor Installation Series graphic EQ’s. The AMIS215EQ & AMIS31EQ are extremely well featured graphic equalizers at a contractor friendly price.

1. Power Switch

This switches the mains power “on” to the unit.

2. Channel 2 Equalizer Section

This section refers to the controls for channel 2. This section is duplicated for channel 1.

3. EQ Filter sliders

These sliders control the output level of the 15 band pass filters in each channel. The centre position will give a flat response.

4. Range Switch.

This switch will change the range of the filter sliders from +/-6db to +/-12dB maximum cut or boost. This switch affects all channel sliders.

5. +/-6dB LED.

This LED will illuminate green when the range switch is set to 6dB.

6. +/-12dB LED.

This LED will illuminate yellow when the range switch is set to 12dB.

7. Bypass Switch.

This switch routs the channels input signal directly to the outputs, bypassing all EQ circuitry. This switch is used to compare EQ’d signal with unequalized material.

8. Bypass LED.

This red LED indicates that the bypass switch is activated for this channel.

9. Channel Level Control

This level control can either cut or boost the output level for each channel. The centre position will give unity gain.

10. Clip LED.

This red LED indicates if any section of the equalizer is within 5dB of clipping. Occasional blinking of this LED is acceptable but a steadier illumination indicates either the EQ’s level controls should be reduced or gain from the preceding audio component should be reduced to avoid distortion.
