Figure 1–2 AMP1-DA/106 Front Panel
Speakers: The AMP1-DA/106 speaker system is comprised of two
mid-range tweeter speakers (left and right) and two woofer
speakers (left and right). The two mid-range speakers reproduce, in
stereo, only the mid and high frequencies, while the two woofer
speakers monorally reproduce the low frequencies.
Headphone Jack: This jack accepts a standard 1/4" stereo (ring/
tip/sleeve) phone plug. Select the headphone audio sources as you
would for the internal speakers. When you plug in headphones, the
internal speakers will mute.
Bar Graph Brightness: This control is recessed into the front panel
and can be accessed using a small flathead screwdriver. Turning the
trim pot clockwise will simultaneously increase the relative
brightness of the LED segments in both bargraphs.
Audio Level Meters: Audio levels for the selected input sources are
displayed via these two 106-segment tri-color (green, amber, red)
LED bargraph display level meters. These two bargraph displays
feature an Auto-Calibration feature and are user adjustable for
Display Mode and Reference Level via a rear panel DIP module.
Peak Hold, PPM Ballistics, and Alternative Scales can be set via an
internal DIP module. See pages 18 and 19 for more information
regarding these DIP switch module locations and settings.
Digital Source Select Switch: This switch selects between the two
AES/EBU In (In 1 or In 2) source inputs. Note that for the
selected AES source to be monitored, the
Analog/Digital Source
Select
switch must be set to Digital.
