Subwoofer Amplifier Controls and Setup
IMPORTANT NOTICE REGARDING BASS MANAGEMENT: It is important the signal being sent to the subwoofer be a non-boosted or “flat” signal. To be sure of this, check the settings on your receiver or processor to make sure any “bass boost”, “super bass” or “loudness” is set to Off. In most cases a home theater receiver or processor will determine the crossover frequency through bass management settings. In this configuration, connect the receiver or processor to the Line Level Input. Your subwoofer will now reproduce the bass frequencies the way they were originally recorded. Use the subwoofer level control and the individual bass management control within the receiver or processor to adjust the subwoofers’ volume if necessary. Once set, the volume controls should not need to be altered as the subwoofers’ volume will track with the master volume control of your receiver or processor.
This section describes the functions and/or use for each of the amplifier controls located on the back of the subwoofer. Refer to the diagrams on the pages 8 and 9.
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. If using this input experiment with setting the crossover frequency control at highest setting initially. Increasing the crossover frequency will allow more mid-bass output from the subwoofer. Decreasing the frequency will allow only deeper bass from the subwoofer.
NOTE: Read the Important Notice regarding bass management above.
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 preamplifier or high level inputs and turns off when no signal has been detected for 15 minutes.
