MartinLogan 1000 - Manual (Page 7)

Level Knob
Setting the level too high will cause the bass to seem bloat-
ed and is the single most common cause of bad sounding
subwoofers. A rule of thumb is that the subwoofer should
not draw attention to itself, but should simply make the sys-
tems low end seem more extended and accurate.
Phase Control Switch
The phase control is entirely dependent on the size and
configuration of your listening environment, the placement
of the unit, and your seating arrangement. Due to the way
bass sound waves develop in different rooms, there is
no rule of thumb for setting phase. For instance, if your
room has a peak at the subwoofer crossover area, you
may wish to set the phase so the actual acoustic outputs
of the subwoofer and main speakers are out of phase.
Experiment, try different settings and be patient.
Crossover
When the Dynamo 1000 is connected in multi-channel
mode (via its Right/LFE input), the crossover switch should
be set to 'Bypass (LFE In)' so that the low pass filter is not
active and your processor handles the bass management.
When connected in 2-channel mode (via its line level left/
right input), the crossover switch should be set to 'Variable
(L&R In)' so that the low-pass filter is active.
Low Pass Filter Knob
When the Dynamo 1000 is connected in multi-channel
mode (via its LFE input), the low pass filter is not active
and your processor handles the bass management. When
connected in 2-channel mode via its line level left/right
input, the low-pass filter is active.
As a general rule the low pass filter should be set equal
to approximately 70% of your speaker’s lowest frequency
response. Remember, this is a general rule. We advise
that once you try the recommended setting using the for-
mula above, you should try the surrounding settings to see
which sounds best.
Wireless Sync Button and Status LED (not shown above)
The wireless sync button is used to establish connection
to the optional SWT-1 MartinLogan Subwoofer Wireless
Transmitter (sold separately and available from your autho-
rized dealer or the Xtatic shop at www.MartinLogan.com).
The Wireless status LED indicates the current status of the
wireless connection (see page 10 for further details).
Status LED (not shown above)
When the status LED (located on the back of the
subwoofer) is blue, the subwoofer is on. When the status
LED is red the subwoofer is in standby mode.
Master Power Switch (not shown above)
Located on the back panel of the subwoofer, the Master
Power switch must be set to 'Auto On' for the subwoofer
to operate. When set to 'Auto On' the subwoofer will
automatically enter a power saving mode when no audio
signal is detected. The subwoofer will automatically come
out of power saving mode when a signal is detected.
