Operating the RESOLV 120a
Control Functions and Indicators
Volume Control
The volume control is used to
adjust the amount of level to the
RESOLV 120a subwoofer. In addi-
tion, the volume control will also
control the output level of the
high-pass outputs. Therefore, if
you are using the RESOLV 120a
without using the high-pass
outputs (for example, when the
RESOLV 120a is connected to an
external crossover) the volume
control adjusts the low frequen-
cy output of the RESOLV 120a. If
you are using the RESOLV 120a’s
internal electronic crossover to
run satellite speakers, then the
volume control will adjust the
overall system level.
Sweep Hz
The Sweep Hz control selects the upper range cutoff frequency of the RESOLV 120a’s internal electronic crossover.
The RESOLV 120a’s crossover provides a 12dB per octave Linkwitz Riley filter curve. The Sweep adjusts the high-
est frequency that the RESOLV 120a will reproduce, and at the same time, the high-pass outputs track the selected
crossover frequency as the lower limit frequency to the satellite speakers.
Power/Protect LED
The POWER/PROTECT LED is a dual color LED which has three states; OFF, GREEN AND RED. The following chart
shows the POWER/PROTECT LED and the different operating conditions it represents.
AUTO ON SWITCH LED - OFF LED - GREEN LED - RED
ON Not Applicable RESOLV 120a - ON PROTECT
AUTO SLEEP RESOLV 120a - ON PROTECT
OFF RESOLV 120a - OFF Not Applicable Not Applicable
If the RESOLV 120a receives a clipped signal for a long duration of time the unit will shut down and enter PROTECT
mode. When the RESOLV 120a is in Protect, you will see the POWER /PROTECT LED is lit up in red. If this happens
simply turn the unit off, wait a minute and then re-power up the unit. The LED should return to a green color again
indicating normal operation . At this point, readjust the level you’re sending to the RESOLV 120a so that the signal is
not clipped and the unit will operate properly.
Auto On Switch
The AUTO ON switch is used to select the RESOLV 120a’s power operating mode. When the switch is set to OFF
the unit is not operational. When the AUTO ON switch is set to the ON position, the unit is always on. To engage
the RESOLV 120a’s SLEEP function, slide the AUTO ON switch to the AUTO position. In this mode, the RESOLV 120a
enters a stand-by, or "SLEEP" condition after no input signal is sensed for a period of approximately 10 minutes. The
RESOLV 120a will return to the normal operating mode as soon as it senses a signal present at the inputs.
Phase Switch
The RESOLV 120a can be switched for inverted phase operation by setting the PHASE SWITCH to the 180° (degree)
position. Experiment with this switch to provide the best blend between the subwoofer and satellite speakers.
