CERWIN-VEGA! PROFESSIONAL
Introduction
Congratulations - Welcome to the Cerwin-Vega! Family! You’ve joined a growing group of audio professionals who have
turned to Cerwin-Vega! for the most advanced audio reproduction systems available. All Cerwin-Vega! products are
thoroughly tested to insure that they meet or exceed our performance specifications. Backed by the best service in the
industry, Cerwin-Vega! is dedicated to quality and reliability. For a complete overview of Cerwin-Vega! products and
services, log onto www.cerwin-vega.com
Before you begin
The Cerwin-Vega! P-Series active speakers covered by this manual are designed for portable applications in which the
speakers will be stacked directly on a floor, stage, stable platform, or mounted on a tripod stand or pole-mount. CerwinVega! does not support suspension of the subwoofer models covered by this manual nor are these models intended for
fixed installation in outdoor or high moisture environments. Moisture can damage the speaker cone or surround and
cause corrosion of electrical contacts so avoid exposing the speakers to direct moisture.
Cerwin-Vega! speakers can generate considerable energy. When placed on a slippery surface such as polished wood or
linoleum, the speaker may move due to its own mechanical vibration. Precautions should be taken to assure that the
speaker does not fall off a stage or table on which it is placed.
Some Cerwin-Vega! speakers include a receptacle cup to allow mounting of a satellite speaker on top of the subwoofer
using a standard speaker pole shaft. When using a standard speaker pole shaft, be sure to observe the following
precautions:
CAUTION: There are a wide variety of pole stands and pole shaft available in the market. Please refer to
qualified service personnel from the pole stands and pole shaft manufacturer for installation service. Improper
use of accessory and inappropriate installation will present a tripping hazard.
Check the speaker pole shaft specification to be certain it is designed to support the weight of the speakers.
Observe all safety precautions specified by the speaker pole shaft manufacturer.
Always verify that the subwoofer is placed on a flat, level, and stable surface.
Route cables so that performers, production crew, and audience will not trip over them, toppling the speaker.
Always be cautious in windy, outdoor conditions as the stability of the entire system may be compromised.

Quick Start
The steps below provide a quick reference on how to setup and use a single loudspeaker. A typical setup will follow the
same basic steps.
Make sure the loudspeaker is unplugged.
STEP 1
STEP 2
STEP 3
NOTE(s)
Be sure the master switch is to set to the ‘OFF’ position.
Turn the Volume to the lowest level (fully counter-clockwise)
Check that the loudspeaker voltage selector is set to the same voltage as the AC power outlet.
Place the loudspeaker in the ideal location. See the Loudspeaker Placement page for
recommended usage.
Connect the source audio equipment output to the loudspeaker input. Be sure the source
equipment is powered on and set to a normal output level.
Connect the power cord to the loudspeaker and AC power outlet.
Set the master power switch to the ‘ON’ position and verify the rear POWER LED indicator is
illuminated.
Slowly turn the volume clockwise until the sound output is at the desired level. If there is no
sound, check to make sure the source equipment is providing audio output.
When you are done using the loudspeaker, set the master power switch to ‘OFF’ before removing
any cables and turning off the source audio equipment.
Do not switch the loudspeaker voltage selector or MIC/LINE switch while the loudspeaker is
powered ‘ON’ and plugged into an AC power outlet.
Loudspeaker placement
Never point a microphone directly at a loudspeaker as this will result in extreme feedback (unwanted sound). Be
sure the loudspeaker is placed away from the front of the microphone or directly behind the microphone when
in a floor monitor position.
When used with turntables, carefully place the loudspeaker so that any vibrations do not interfere with the
turntable performance and functionality.
Avoid placing the loudspeaker in the corners or along the walls of a room. This will increase the low-frequency
sounds and the sound will result in a muddy and incoherent sound reproduction.
Avoid placing the speakers directly on a hollow stage. It is better to place the loudspeakers on tripod stands or a
sturdy table.
The loudspeaker should be placed two to four feet above the ear level of the audience since the human body
can absorb sound especially at high frequencies. This will make sure the entire audience can hear the sound
system with the best possible clarity.

(C) SIGNAL/CLIP INDICATORS
Each of the three inputs is monitored by an indicator that provides status on the incoming audio signal. The SIGNAL
indicator is illuminated when there is an audio signal present with a level greater than -30dBu, approximately the lowest
level before a MUTE condition. The CLIP indicator is illuminated when the audio signal is clipping and adjustments must
be made to avoid amplifier shutdown and poor sound quality. Adjustments to prevent clipping are made by reducing the
input signal gain/level on the appropriate channel or reducing the volume level on your audio source, if possible.
(D) INPUT 1 & INPUT 2 INPUT JACKS
A combination input on each channel allows for either XLR or ¼” TRS cable types.
(E) INPUT 3 INPUT JACKS
A pair of ¼” TS unbalanced input jacks is provided on this channel for stereo connections such as a keyboard or media
device. Devices with RCA outputs can use these inputs with the appropriate cable or plug adapter. Both input jacks on
this channel are summed into one mono signal.
(F) THRU 1 & THRU 2
The balanced XLR outputs THRU 1 & THRU 2 are parallel connections to the respective INPUT 1 and INPUT 2. The level
controls for INPUT 1 & INPUT 2 will not affect the signal on the direct output connection.
(G) MIX OUTPUT
This is a balanced XLR output that is a sum of all three input channels. This output is not affected by changes to the
Main Volume knob or the custom features but is affected by the levels set on each channel level knob. This connection is
designed to provide an output which combines all three input channels together for connecting to another
P1000X/P1500X powered speaker or a recording device.
(H) MAIN VOLUME KNOB & REMOTE VOLUME CONTROL
It is highly recommended to have the volume set to the minimal (MIN) level upon initial system start-up and it can be
adjusted two different ways. On the main volume knob, volume is increased in a clockwise rotation and decreased in a
counter-clockwise rotation. Another method to control the volume is by using the Remote connection (sold separately).
A removable three-terminal jack can be wired over long distances to a remote volume control device with a
corresponding connection.
(I) INDICATORS
Three indicators provide operating condition status on the P1000X/P1500X:
1) The POWER indicator (green) will illuminate when power is properly applied to the P1000X/P1500X and the
main power switch is ‘ON’.
2) The LIMITER indicator (yellow) will illuminate when the P1000/P1500X automatically reduces the sound output
to prevent damage to the speaker. While the P1000X/P1500X is producing sound, it is suggested to reduce the
volume level so the LIMITER indicator does not illuminate. Continuing use of the P1000X/P1500X while this
indicator is illuminated may result in a protect condition where no sound can be produced.
3) The PROTECT indicator (red) will illuminate when the P1000X/P1500X automatically places itself into a condition
where sound output is shutoff. This condition may be the result of excessive limiting, an excessive heat
condition, or a low voltage condition. These conditions all can cause significant damage to the product.

(J) CUSTOM FEATURES
ENHANCED EQ SWITCH
The ENHANCED EQ switch adjusts the contour of the overall frequency response and attenuates the mid-range
frequencies which helps increase focus on the low and high frequencies while potentially reducing feedback. This
feature is ideal for situations where an external mixer or EQ device is not available or playback only situations such as
mobile DJ’s. It is recommended that users listen to their system with this switch both on or off to determine what is
best for their needs.
VEGA BASS BOOST SWITCH
Engaging the VEGA BASS BOOST switch to ‘ON’ adds low frequency gain to the signal and dynamically adjusts the lowfrequency response based on the speaker volume level. Leaving the switch ‘OFF’ and engaging the HIGH PASS FILTER is
recommended when using the P1000X/P1500X with a subwoofer. When using the P1000X/P1500X with the P1800X
subwoofer it is also recommended to engage the HPF THRU & LPF SUB switch on the P1800X for the best performance.
HIGH PASS FILTER SWITCH
When engaged to ‘ON’, the HIGH PASS FILTER (HPF) switch attenuates overall frequency output below 80Hz. This is
recommended to reduce stage rumble when the speaker is used as a floor monitor or in situations where low
frequencies need to be attenuated such as in combination with a subwoofer.
FRONT LIMITER LIGHT SWITCH
Setting the FRONT LIMITER LIGHT switch to ‘ON’ will enable the limiter indicator light on the front of the P1000X/P1500X.
This allows the user to see when the limiter is engaged in situations where it needs to be visible such as during a sound
check.
