Clever Features, Contractor Friendly AMIS215EQ Stereo 15 band 2/3 Octave Graphic Equalizer AMIS31EQ Mono 31 band 1/3 Octave Graphic Equalizer Installation And Operation Manual
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.
Front Panel AMIS215EQ 1 2 2 3 4 5 6 7 8 9 10 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.
Front Panel AMIS31EQ 2 1 2 3 4 5 7 6 8 10 11 9 1. Power Switch This switches the mains power “on” to the unit. 2. Enlarged Equalizer Section This section refers to the controls for equalizer. 3. EQ Filter sliders These sliders control the output level of the 31 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.
Back Panel AMIS215EQ/AMIS31EQ 1 7 2 3 4 5 8 6 1. Back Panel Section. This section refers to the back panel for the AMIS31EQ. This section is duplicated for channel 1 & channel 2 of the AMIS215EQ. 2. 6.35mm TRS Input Jack. This line level input accepts a balanced 6.35mm TRS jack. The balanced connector should be wired tip=Positive, Ring=Negative & sleeve=Ground. 3. Balanced XLR Input. This input again accepts a line level signal with the XLR wired Pin2=Positive, Pin3=Negative & Pin1=Ground.
4. 6.35mm TRS output Jack. This is the line level output of this channel. The 6.35mm jack should be wired as point (2). 5. Balanced XLR output. This is the balanced XLR line level output of this channel. The XLR should be wired as point (3). 6. Unbalanced RCA Input/Output. These RCA Input/Outputs provide an unbalanced line level input & output. The RCA connectors should be wired Tip=Positive Sleeve=Ground. Note: Only one style of connector should be used at one time. 7. Ground Lift Switch.
3. Set all slider controls to the centre detent 0dB position. 4. Set the range switch to the 6dB position (green LED illuminated). 5. Apply signal to the audio system. 6. Release the bypass switch (red LED off) 7. If the overload LED illuminates you may need to turn the level control down until the LED flashes occasionally or is off. 8. Equalize your audio system as desired. 9.
