• Speakers: The AMP2s features two mid-range speakers (left and

right) and one woofer speaker. The AMP1s have two woofers. All

models of the AMPx-X8 Series contain high performance

transducers driven by three power amplifiers. Two amplifier/

driver combinations handle midrange and high frequency

information in the left and right (stereo) speaker channels, while the

third channel reproduces and sums the left and right channel

information below the crossover point in the woofer (bass) speaker.

Note that the woofer channel is not a dedicated LFE (sub-woofer) or

center channel.

• Level Meters (1 through 8): Source channels 1 through 8 are

displayed through eight audio level meters (four on the left side;

four on the right side). These level meters, high-resolution LED bar

graph displays and feature a dynamic range of 66 dB with PPM dot

channel) will respond to balance adjustments in tandem with the

left and right speaker channels.

• Level Meter Brightness (Potentiometers, Left and Right): Use a

small slot screwdriver to adjust the brightness of the bar graph

meters using these two recessed trim pot controls. The left control

adjusts the brightness of the left four LED bar graphs and the right
