• Speakers: The AMP1 V Series monitors feature two mid-range
speakers (left and right) and two woofer speakers (one woofer in the
AMP2 models). 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 500 Hz crossover point in the woofer (bass)
speaker. Note that the woofer channel is not a dedicated LFE
(subwoofer) or center channel.
• Headphones: This jack accepts a standard 1/4" phone type stereo
plug. When you plug in headphones, the internal or external
speakers will mute.
• Source or Left Speaker/Right Speaker (Assign): Use the left bank
of four buttons to assign one to four of the four available channels
for monitoring from the left speaker channel. Use the right bank of
four buttons to assign one to four of the four available channels for
monitoring from the right speaker channel. Channel buttons toggle
on/off and will light up blue to indicate they are selected. Operation
for each bank of four buttons is as follows:
• Single Channel Select: Press and release a single channel
button to select that channel (and deselect any previous
selection). Pressing and releasing the selected channel button
again will deselect it.
• Multi-Channel Select (Summing): Press and hold down a
desired channel button, then press other channel buttons to
add (sum) additional channels (or press any again to
deselect). Release all buttons to accept the selection set. When
multiple channels are selected, pressing and holding an
already selected channel button will allow further
modification to the selection set. Releasing all buttons accepts
the new selection set. Pressing and immediately releasing an
already selected channel button will select only it and deselect
all other channel selections.
If the user presses a previously selected (lighted) channel button,
but then decides not to make any changes to the selection set, the
user should keep the button depressed for at least 1.5 seconds
