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, (10) to the proper aC voltage.

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.

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!
1. 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)
2. 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)
3. SpEakER-lEVEl InpUt: Stereo high-level inputs (3) 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)
4. SpEakER-lEVEl oUtpUt: Audio loop of stereo high-level (SPEAKER-LEVEL)
inputs (3). Use to loop (continue) signal to speaker connections to the left and right main speakers.
5. VolUME ContRol: Controls volume level of subwoofer. Use to balance the output
of the subwoofer with the main speaker output.
6. 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 FREQUENCY to the lower value listed in the
main speaker manual.* (NOTE: Crossover control does not function when LFE input is used.)
7. 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.”
8. 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.
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. 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.
11. 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.
12. 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.

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.

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