RIOR TO INSTALLATION

Carefully unpack your subwoofer, saving the box and all of the packing material; at

some point you may need to transport, ship, or move your subwoofer. Before
continuing with the installation, please make sure the subwoofer is unplugged and
the power switch is turned “OFF.”

WARNING: Severe damage may result from

improperly selected voltage. Set voltage selection switch, to the proper AC voltage.

NSTALLATION

Please read the following to determine which installation procedure is best for your

audio/video system. For additional hook-up connections, you may want to refer to
your A/V receiver, processor, preamplifier, or amplifier’s manual.

NOTE: Be sure to read

and observe the “Safety Instructions” on preceding page before starting the installation.

ONTROL

ESCRIPTIONS

The following controls are located on the subwoofer’s rear panel, as shown (back cover).

Attention! The Cerwin-Vega VE-28S have LFE, LINE-LEVEL, and SPEAKER-

LEVEL input connections; choose one option only for hook-up. Do not hook up

more than one option!

LFE INPUT:

Mono “low frequency effects” connection. Use this input if

receiver/preamp/processor has a dedicated LFE or subwoofer OUT.

Refer to

the owner’s manual provided by your receiver/preamp/processor manufacturer.
(see figure 1, back cover for hook-up)

LINE-LEVEL INPUT:

Stereo low level input to subwoofer. Connect to “LINE-OUT”,

“MAIN-OUT or PREAMP-OUT”, of your receiver/preamp/processor using a dual RCA
patchcord (not supplied).

Refer to the owner’s manual provided by your receiver/

preamp/processor manufacturer. (see figure 2, back cover for hook-up)

SPEAKER-LEVEL INPUT:

Stereo high-level inputs to subwoofer. Use these terminals

when line-level connections are not available from A/V receiver/preamp/processor.
Connect to SPEAKER outputs on receiver using high quality speaker wire (16-gauge
or heavier).

(see figure 3, back cover for hook-up)

SPEAKER-LEVEL OUTPUT:

Audio loop of stereo high-level (SPEAKER-LEVEL)

inputs . Use to loop (continue) signal to speaker connections to the left
and right main speakers.

VOLUME CONTROL:

Controls volume level of subwoofer. Use to balance the output

of the subwoofer with the main speaker output.

CROSSOVER FREQUENCY:

The crossover control allows you to adjust the upper

limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s
response will begin rolling off above the set frequency. Set the CROSSOVER FRE-
QUENCY to the lower value listed in the main speaker manual.* (Note: Crossover
control does not function when LFE input is used.)

PHASE:

This switch allows you to compensate for having the subwoofer

in a different location than the main speakers. This control allows the signal to be
delayed 180 degrees so the output of the subwoofer will blend in with the
main speakers. Slide the PHASE switch to “180”. At the listening position, listen to
the midbass output. If it sounds weak, set PHASE back to “0.”

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.

OTES

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.

VOLTAGE SELECTION:

User-switchable voltage selection for use with 110-120V/

220-240V AC.

Attention: All subwoofer models come from the factory preset to

110-120 volts.

To select a different voltage, use a flat head screwdriver to reposition

the switch to the desired voltage.

WARNING: Severe damage may result from

improperly selected voltage. Make sure you know the voltage requirement of

the country you are in before attempting to connect this subwoofer to AC

power.

POWER CORD RECEPTACLE:

Connect IEC cord to this receptacle (supplied

with the VE subwoofer). If the cord supplied does not fit an available AC outlet,
purchase the correct AC cord from your audio dealer or an electrical supply store.

REPLACEABLE FUSE:

Protects system from overload, replace with fuse rating as

indicated on amplifier panel at fuse location. The fuse holder is located at the AC
receptacle. Gently pry open to access the fuse.

LACEMENT

Your VE Series powered subwoofer produces low frequencies which are omnidirectional.

As a result, placement requirements for your subwoofer are flexible and subject to your
listening room’s acoustic characteristics. To determine the best position for your
subwoofer, start by positioning it along the same wall, or plane, as your main speakers.
Experiment with various locations until you find the location that sounds best to you.

Note: Typically, your powered subwoofer will sound louder when placed in close
proximity to walls or corners.

Caution! Cerwin-Vega VE-28S speakers are intended for FLOOR

PLACEMENT ONLY! Do not place heavy objects of any type, such as televisions on

top of any Cerwin-Vega speaker unless otherwise recommended by Cerwin-Vega!

VE Series speakers are for residential applications only.

S u b w o o f e r I n s t a l l a t i o n

* Refer to the owner’s manual provided by your main speaker manufacturer to
determine your main speaker’s low end frequency response.
