WARNING: Changes or modifications to this unit is prohibited and any changes made that are not expressly approved
by Cerwin-Vega! Inc in writing will void the warranty and any subsequent claims that arise and made to Cerwin-Vega!
Connections:
1. CROSSOVER & SUBWOOFER INPUTS:
Some models can be BiWired or BiAmped:
•LA44, LA165, LA265 and LA365: allows the user to gain diect access to the woofer or tweeter independantly
by first removing the jumper bars.
•Top two terminals are the tweeter.
•Bottom two terminas are the woofer(s).

Connecting your Front Speakers:
The passive speakers all use an input terminal cup type of connection as shown in Figure 1 below.
Figure 1: Speaker Terminal Connection
Note: it is recommended that you turn your receiver and or amplifier volume down to a minimum that you
plan to use to power your speakers and then power off the receiver and or amplifier before attempting to
connect speaker wires to your receiver and or amplifier.
Connect your Left and Right front speakers first with speaker wires to the terminal connections as shown in
Figure 1 above.
Connect the other end of the speaker wire to your receiver / amplifier power output connections, please see
Figure 2, example shown below.
Figure 2: Receiver High Level Output to Front Speakers
Note: when plugging up each speaker, be sure to connect the (-) speaker terminal to the receiver / amplifier
(-) terminal that you will be using as your sound source.
Connect the (+) speaker to (+) between the speaker to the receiver / amplifier (+) terminal that you will be
using as your sound source.
Failure to connect properly may result in an out of speaker phase condition that may result in a diminished
overall sound.

5
Connecting your Center Channel:
Referencing figure 3 below, the center channel is a passive speaker and audio connections are made via the
input terminal cup either using a banana style of plug or simply unscrewing the metal hex nut connector and
placing the wire into the hole in the shaft then retighten the connection. Connect the other end of the
speaker wire to your receiver / amplifier “CENTER” channel output connections, please see Figure 3,
example shown below.
Note: Before attempting to connect speaker cables to your receiver or amplifier, it is also advised that you
decrease the volume of the device down to the lowest setting that you intend to use to power your speakers
and then turn the device off. Make sure to connect the (-) speaker terminal on each speaker to the (-)
receiver or amplifier terminal that will serve as your sound source.
Use only a high-quality grade of speaker wires to the center channel input terminal connections and your
receiver / amplifier.
An improper center channel connection could cause the speakers to be out of phase, which would degrade
the overall sound, but will not harm the speaker or receiver/amplifier.
Figure 3 Center Channel Input terminals and Receiver Center Channel output connections.

6
Connecting your Surround Sound Speakers:
Referencing figures 4 & 5 below, the surrounds are passive speakers positioned typical just behind where the
person sits to the left and right sides.
Connections to the left and right channel surrounds are made via the input terminal cups. Connections can
be made using either a banana style of plug or simply unscrewing the metal hex nut connector and placing
the wire into the hole in the shaft then retighten the connection. Connect the other end of the speaker wire
to your receiver / amplifier “SURROUND” LEFT AND RIGHT channel output connections, please see Figure 4,
example shown below.
Note: Before attempting to connect speaker cables to your receiver or amplifier, it is also advised that you
decrease the volume of the device down to the lowest setting that you intend to use to power your speakers
and then turn the device off. Make sure to connect the (-) speaker terminal on each speaker to the (-)
receiver or amplifier terminal that will serve as your sound source.
Use only a high-quality grade of speaker wires when connecting the surround speakers to your receiver /
amplifier.
An improper surround speaker connection (reverse polarity) could cause the speakers to be out of phase,
which would degrade the overall sound, but will not harm the speaker or receiver/amplifier.

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.
