How to Set a Band-Pass Filter
To build a proper band-pass filter, the low-pass
frequency must be greater than the high-pass
frequency. The MS-A1004 will not allow you to set
the low-pass filter frequency to a lower value than
the high-pass filter frequency. To enable a band-pass filter, first select the High-Pass Filter frequency and slope, as
indicated above. Next, select the low-pass filter frequency and slope. Once the settings are complete, the controls
will time out after 15 seconds.
OUTPUT LEVELS
Setting the Output Level
Use the Output Gain Control to adjust the balance between the subwoofer and the full-range speakers,
between the front and rear speakers, or between the midrange, mid-bass or tweeters in a bi-amped or
tri-amped (all active) system. The output level is adjustable in 0.5dB increments, with a display of 80 indi-
cating maximum output. The lowest setting will mute the output and "
To set the output level, press the CW or CCW buttons to highlight the output-level parameter for adjustment, and
turn the rotary controller to adjust the output level.
WIRELESS BASS CONTROL
Overview
The MS-WBC (sold separately) is battery-powered and also
vehicle. The MS-WBC transmits a signal only when the control is
rotated. The amplifier(s) must be on to receive and respond to the
control, so adjustments made to the control when the amplifier(s)
is/are off aren't recognized.
How to Pair the MS-WBC Wireless Bass Control with the MS-A1004
The optional MS-WBC wireless bass controller must be paired to the amplifier in order to be used. When the ampli-
fier is first turned on, the amplifier is not paired with any controller.
Press and hold both CCW and CW buttons simultaneously for more than three sec-
onds and the amplifier will enter Setup mode. Continue pressing the buttons for four
more seconds until the pairing indicator
buttons.
Pairing must occur within 15 seconds. The time remaining is indicated at the far right
of the display. Turn the knob on the bass controller during this 15-second period. The
wireless bass controller will be recognized by the amplifier and will automatically pair
the two together.
After a successful pairing, the upper HP filter digits will display the bass controller
version number for three seconds. Then the amplifier will return to the normal (RUN)
mode.
If a valid pairing has not occurred, the amplifier will remain unpaired. After the 15-sec-
ond countdown, the amplifier returns to the Setup mode.
If your system includes several MS Series amplifiers, pair them one at a time. Once all
the amplifiers are paired and have returned to the normal (RUN) mode, turn the knob to
synchronize all amplifiers.
