Two-Way/Bi-Amped Speaker: The Cerwin-Vega P1500X is a two-way, bi-amped,
full-range bass-reflex speaker. It employs a 15" woofer and a 1.75"
high-frequency compression driver, powered by a custom 1500W Class-D amplifier.
A proprietary hemi-conical horn provides premium sound clarity over an even and
wide coverage area.
Rugged Enclosure: The enclosure is built of a lightweight, robust
polymer featuring integrated ribs for durability and resonant free performance.
The enclosure also includes a steel-mesh grille and comfortable ergonomic
Inputs/Outputs: The P1500X offers a variety of inputs and outputs for
different sound reinforcement applications.
- 3 Inputs: Both, Input 1 & 2 feature a balanced combination input
which allows for either XLR or1/4" TRS cable types. Input 1 & 2 can be set
to Mic (2kohm) or Line (40kohm). Input 3 consists of a pair of 1/4" TS
unbalanced input jacks for stereo connection, such as a keyboard or media
device. Both Input 3 jacks are summed into one mono signal
- Outputs: The balanced XLR "THRU 1" & "THRU 2" outputs are
parallel connections to the respective Input 1 and Input 2 channels. The
level controls for Input 1 and Input 2 will not affect the signal on the
direct output connection. The "Mixer Out" 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 P1500X powered speaker or a recording device.
Mixer Controls: The Cerwin-Vega P1500X's mixer controls enable
exact tuning and exceptional performance for any sound reinforcement
- Volume: The main volume knob increase the overall output of the
powered speaker. Volume is increased in a clockwise rotation and decreased
in a counter-clockwise rotation.
- Input Level: Each level knob adjusts the gain level on the
respective input signal. The full clock-wise position (MAX) sets the gain
level to maximum whereas a full counter-clockwise (MIN) position sets the
gain level to the minimum "MUTE" level. It is recommended to set each level
knob to the middle position and the main volume knob to the MIN or fully
counterclockwise position when first connecting the system.
- Enhanced EQ: 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: Engaging the VEGA BASS BOOST switch to "ON" adds
low frequency gain to the signal and dynamically adjusts the low-frequency
response based on the speaker volume level. Leaving the switch "OFF" and
engaging the High Pass Filter is recommended when using the P1500X with a
subwoofer. When using the P1500X with the P1800X subwoofer it is also
recommended to engage the HPF THRU & LPF SUB switch on the P1800X for the
- High Pass Filter: 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.
Status Indicators: The P1500X features LEDs to indicate Power, Signal,
Clip, Limiter, and Protect status.
- Power: The POWER indicator (green) will illuminate when power is
properly applied to the P1500X and the main power switch is ON".
- 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.
- Clip: 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.
- Limiter: The LIMITER indicator (yellow) will illuminate when the
P1500X automatically reduces the sound output to prevent damage to the
speaker. While the P1500X is producing sound, it is suggested to reduce the
volume level so the LIMITER indicator does not illuminate. Continuing use of
the P1500X while this indicator is illuminated may result in a protect
condition where no sound can be produced. Note, upon initial power up the
indicator will blink. This is normal behavior as it will indicate the
firmware version in the unit.
- Protect: The PROTECT indicator (red) will illuminate when the
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.
Mounting Options: The Cerwin-Vega P1500x's angle-adjustable pole mount
socket, side-wedge shaped enclosure, and M10-threaded suspension points support
a variety of permanent and portable setups.
- Studio Monitor: The P1500X can be used as a floor monitor by
laying the cabinet on its side at a fixed 45-degree angle toward the
performers. It is recommended to engage the High Pass Filter which cuts low
frequencies to minimize any low frequency bass-coupling or stage rumble
between the loudspeaker and the stage platform. Be sure that the P1500X and
cables are not located where they can become a tripping hazard. It is
recommended to use right angle XLR or right angle 1/4" jacks where possible
to avoid cable binding between the loudspeaker and stage platform.
- Pole Mounting: The P1500X has two different pole mounting angles;
level and 7.5-degrees down. This allows the loudspeaker to be adjusted to an
angle that provides optimal audience coverage. For example, a loudspeaker
placed on a raised stage platform may have the pole mount adjusted to
7.5-degrees downward so the front audience will not be missed. Adjust the
pole mount angle on the loudspeaker before it is placed onto a pole. On the
bottom of the loudspeaker is a rotating disc with two tabs and a position
indicator. Use the two tabs to rotate the disc so that the position
indicator is aligned with either 0 (level) or 7.5 (angle downwards). Be sure
the disc "clicks" into place and cannot rotate freely.
- Suspension Points: The P1500X suspension points are M10 threads
with a depth of 25mm. Two suspension points are located on each handle (top
for vertical orientation and on the side for horizontal orientation) as well
as two pull-back points located on the rear of the unit.
Applications: The Cerwin-Vega P1500X is well suited
for almost any sound reinforcement application, from live performances to DJ
gigs, as well as public speaking engagements. The P1500X is a versatile
product that can be used as a single speaker for a small venue, set in pairs,
paired with a powered sub for a larger venue needing more coverage and SPL.
- Single: A single P1500X powered speaker can be used to reinforce
sound for a wide variety of performances. For example, a vocal microphone,
an acoustic-electric guitar, and either a keyboard or media player can be
connected to the speaker. Each individual channel volume can be adjusted to
create the right balance while the main volume knob controls the overall
- Stereo: A second P1500X loudspeaker can easily be added using a
standard XLR/mic cable. A two speaker system can cover a wider audience and
situations where more volume is needed. To add a second P1500X loudspeaker,
connect the Mix Output of the first speaker to Input 1 or Input2 on the
second speaker then set the level and main volume to an appropriate setting
on the first speaker. Be aware that the main volume on the first speaker
will not change the volume on the second speaker so make sure to set the
input and main volume knobs to similar settings.
- Add A Sub: For demanding applications where even greater bass
response is ideal, adding subwoofers to a pair of P1500X speakers is a great
idea. Your audio source is connected to Input 1 on the P1800SX subwoofer
(sold separately) and then the signal is linked to the P1500X speakers by
using the P1800SX Thru 1 outputs.
- Daisy Chained: Some events may require several P1500X speakers
spread across a long distance or a large stage front to provide adequate
sound reinforcement for the entire audience. Since there are multiple
sources, the loop out from the mix output should be used to daisy-chain to
the next P1500X and then use the thru-out from the second speaker onward.
