MODEL NUMBERS: These are the particular loudspeakers and subwoofers for which the MX8700 is
configured.
OUTPUTS: These correspond to the output connectors and are listed on the label as:
S = SUB
L = LOW
M = MID
H = HIGH
OUTPUT USE: The uses are listed on the label as:
sub = subwoofer (for separate subwoofer system)
low = low frequency (for 2-way and 3-way loudspeakers)
l/m = low/mid (for 3-way loudspeakers with a passive low/mid crossover)
mid = mid frequency (for 3-way loudspeakers)
m/h = mid/high (for 3-way loudspeakers with a passive mid/high crossover)
hi = high frequency (for 2-way and 3-way loudspeakers)
n/c = no connection. The output is not used for this configuration.
EAW PART #s: These are the MX8700 part numbers for the factory loaded presets for each channel.
4.2
Front Panel Controls / Indicators
4.2.1 Power LED
The
POWER
LED indicates that the unit is powered and turned on. The power switch is located on the
rear panel.
4.2.2 Input Headroom Indicator
The
INPUT
headroom indicator is a six-segment peak-responding bar graph that indicates the signal level
from -20 dBu to clipping. The headroom indicator monitors the input to the A/D converter, after the input
level control. Ideally, you want the highest peak level to illuminate the +12 dBu segment, but not the CLIP
segment.
You can set the level lower than this, but understand that you are reducing the signal-to-noise ratio.
4.2.3 Sub Mode Switches
There are three “
SUB
” switches that match the operation of the MX8700’s
SUB
outputs to the operating
conditions of the subwoofers.
Ch 1 SUB
and
Ch 2 SUB
adj
- Adjacent mode: This mode provides a true low pass / high pass crossover between the LOW
frequency output and SUB output. Use this mode when the main system and the subwoofers are
arrayed together. This configuration typically provides the flattest overall response.
off
- Off Mode: In this mode the SUB output is turned off. The LOW frequency output is reconfigured
for extended bandwidth operation by lowering the high pass filter frequency and adjusting equalization
and protection parameters.
dis
- Distant Mode: This mode overlaps the crossover frequencies between the SUB and LOW out-
puts. Use this mode when the subwoofers are located remotely from the main speaker system. The
overlap minimizes the dislocation of the sonic image caused by the remote location of the subwoofers.
inv
– Inverted Mode: The inverted mode inverts the polarity of the SUB output relative to the LOW
output for that channel. The setting for this parameter depends on the relative locations of the main
and subwoofer systems. You can determine the setting for this parameter by using proper test equip-
ment or you can do it the old fashioned way: by ear.
