Impression Series 6 Owner’s Manual
This section describes the functions and/or use for each of the amplifier controls
located on the back of the subwoofer. See the diagram of the back of the subwoofer
on the next page.
1. Voltage Selector Switch:
Before connecting the amplifier to any power source
make sure the AC Voltage Selector is set to either 110V or 220V to match the
power voltage in your area.
WARNING! If the voltage setting does not match the AC power supplied,
damage to the Subwoofer Amplifier may result.
2. Volume/Gain Control:
The volume/level control should be at the minimum
setting (all the way counter-clockwise) before plugging the subwoofer into an
AC wall socket. Once plugged in, turn the level control up one quarter of a turn
(9 o’clock position) for an initial setting. The level control may be adjusted
while playing to match the subwoofer level with the rest of the system.
IMPORTANT! The volume control should be at the minimum setting (all the way
counter-clockwise) before plugging the subwoofer into an AC wall socket.
3. Crossover Frequency Control:
The variable crossover frequency control allows
you to set the low-pass crossover point of the subwoofer anywhere from
40-150 Hz. Increasing the crossover frequency will allow more mid-bass output
from the subwoofer. Decreasing the frequency will allow only deeper bass from
the subwoofer. Experiment with setting the crossover frequency control at
highest setting initially.
NOTE:
Read the Important Notice regarding bass management on page 4.
4. Auto Signal Tracking:
The subwoofer amplifier uses “smart” signal tracking
circuitry. Once the power cord is plugged in and the switch set to auto, the amplifier
automatically turns on when a signal is detected at the Line or LFE inputs and turns
off when no signal has been detected for about 15 minutes.
5. Phase Control: This control changes the phase of the subwoofer. Changing
the phase will change the way the subwoofer and main speakers interact with
each other at the crossover frequency. Varying the phase position may result
in more or less mid bass depending on the phasing between the main speakers
and the subwoofer. Generally, the phase is left at the “0 degrees” position.
6. Line Inputs:
Line level inputs are used to connect to most full-range stereo receivers
or processors, use both the L and R terminals.
7. LFE In:
The Low Frequency Effect input is to connect to the “LFE” bass
management output of the receiver or processor and may also be called
“Subwoofer Output”.
