• 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
over VU bar ballistic characteristics.
• Headphones (1/4" Jack): Select the headphone audio sources as
you would for the internal speakers. When you plug in headphones
the speakers will mute.
• Volume (Rotary Knob): This control adjusts the loudness of the
audio reproduced by the internal speaker channels or connected
headphones.
• Balance (Rotary Knob): This control adjusts the volume balance
between the left and right speaker channels. Note that this control
attenuates the signal from the source, so that the left and right bass
frequencies (summed together and reproduced in the woofer
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
Figure 2–1 and Figure 2–2 on the next page.
