The following controls refer only to the LA110 subwoofer.
1. PHASE: speaker phase (0° to 180°) refers to sound waves arriving to the listener from multiple speaker boxes in
the room at the same time being in step with each other.
Sometimes for various reasons not covered in these instructions, speaker sounds from a speaker can arrive out of
phase as compared to other speakers which can cause a diminished overall sound to arrive at the listeners
positions.
When audio arrives being out of phase the sound from each speaker can cancel some of the sound resulting in an
overall diminished sound level. By switching the speaker phase switch from a state to another state can help to
clear up any diminished bass sounds.
2. POWER LED: Power indicator lamp. Glows green in "ON" mode if audio signal is present. Glows red in both "OFF"
mode and "ON" mode if receiving AC power, and if audio signal is not present after approximately 30 minutes.
3. Auto Switch: Two-position power switch. In the "ON" mode, the subwoofer's amplifier is automatically activated
if an audio signal is present and will automatically become inactive when there is no audio signal present after
approximately 30 minutes. In the "OFF" mode, power is shut off to the amplifier.
4. CROSSOVER LEVEL: Allows the user to adjust the crossover frequency between 50Hz to 150Hz.
5. LEVEL: min and maximum for volume level.
6. Line Level Input/LFE: Low signal level input from Receiver or other low-level sources.
7. High Level Inputs: subwoofer can accept high level inputs from amplifier/receiver
8. High Level Outputs: provides a high-level loop through connection to the front speakers.
9. POWER: Two-position power switch. In the "ON" mode, the subwoofer's amplifier is automatically activated if an
audio signal is present and will automatically become inactive when there is no audio signal present after
approximately 30 minutes. In the "OFF" mode, power is shut off to the amplifier.
10. POWER CORD RECEPTACLE: Connect the IEC power cord to this receptacle (supplied with the subwoofer). If the
IEC cord does not fit in your AC outlet, please purchase another AC cord from your audio dealer or electrical
supply store.
11. REPLACEABLE FUSE: Protects system from overload. Refer to qualified service personnel to change the fuse.
12. VOLTAGE MAINS: the subwoofer can accept AC Mains voltage ranging from 100VAC to 240VAC. The appropriate
power cord must be used depending on the country voltage being used.
