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 ensure 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, visit www.cerwin-vega.com
Before you begin
This manual covers the CVXL-Series active speakers: the CVXL-112, CVXL-115, and CVXL-215 (referred to as “tops”) and the CVXL-118s and CVXL-218s (referred to as a “subs”). These speakers are designed for portable applications (such as being mounted on a tripod stand or pole mount or stacked directly on a floor, stage, or stable platform) and fixed installations (such as being “flown” or suspended using appropriate wall/ceiling mounting hardware). These speakers are not intended for fixed installation in high-moisture or outdoor environments, as moisture can cause corrosion of electrical contacts and damage the speaker cone or surround. Cerwin-Vega does not support suspension of the subwoofer models covered in this manual.
Cerwin-Vega speakers can generate considerable vibrational 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 when in operation.
The CVXL-118s and CVXL-218s subwoofers include a receptacle cup to allow mounting of a satellite speaker using a standard speaker pole shaft. When using a standard speaker pole shaft, be sure to observe the following precautions:
There are many types of pole stands and pole shafts available. Please refer to qualified service personnel from
the pole stand and pole shaft manufacturers for installation service. Improper use of accessories or inappropriate installation could present a hazard.
Check the speaker pole shaft specification to be certain it is designed to support the weight of the speaker. Observe all safety precautions specified by the speaker pole shaft manufacturer. Always verify that the subwoofer is placed on a surface that is flat, level, and stable. Route cables so that they will not be tripping hazards. Always be cautious in windy outdoor conditions, as the stability of the entire system may be compromised.

STEP 1
Make sure the loudspeaker is unplugged from the AC mains. Be sure the power switch is set to the OFF position. Turn the LEVEL knob to the lowest level (fully counterclockwise).
STEP 2
Place the loudspeaker in the intended location. 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.
STEP 3
Connect the power cord to the loudspeaker and AC power outlet. Set the POWER switch to the ON position and verify the POWER LED indicator is illuminated. Slowly turn the LEVEL knob clockwise until the sound output is at the desired level. If there is
no sound, check to make sure that the source equipment is providing audio output.
NOTES
When you are finished using the loudspeaker, set the POWER switch to the OFF position BEFORE removing any cables or turning off the source audio equipment.
Quick Start
The steps below provide a quick reference on how to set up and use a single loudspeaker. A typical setup will follow the same basic steps.
Loudspeaker Placement
Never point a microphone directly at the loudspeaker, as this will result in feedback (unwanted sound). Be sure
the loudspeaker is placed away from the front of a microphone or directly behind a microphone when it is in a floor monitor position.
When used with turntables, the loudspeaker should be carefully placed so that any vibrations do not interfere
with the turntable performance and functionality.
Avoid placing the loudspeaker in corners or along the walls of a room. Doing so will increase the low-frequency
sounds, which will result in a muddy and incoherent sound reproduction.
Avoid placing the speaker directly on a hollow stage. It is better to place the loudspeaker on a tripod stand 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 ensure that the entire audience can hear the sound system with the best possible clarity.

Rear Panel - Mixer - CVXL-112, CVXL-115, CVXL-215
INPUT 1, INPUT 2, INPUT 3 GAIN KNOBS
Each 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 Level knob to the MIN or fully counter-clockwise position when first connecting the system.
INPUT 1, INPUT 2 MIC/LINE SWITCH ES
Set each switch according to the equipment connected to INPUT 1 and INPUT 2. For example, if a microphone is connected to INPUT 1, set the switch to ‘MIC’. If a mixing console or acoustic-electric guitar is connected then set the switch to ‘LINE’.
NOTE: The input switch must be properly set to the device that is connected to the input. Any mistake may result in unexpected sound level.
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. 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.
INPUT 1 & INPUT 2 INPUT JACKS
A combination input on each channel allows for either XLR or ¼” TRS cable types.
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.
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.
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 Level knob or the custom features but is affected by the levels set on each channel gain knob. This connection is designed to provide an output which combines all three input channels together for connecting to another CVXL powered speaker or a recording device.

MAIN LEVEL KNOB & REMOTE VOLUME CONT ROL
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 Level 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.
INDICATORS
Three indicators provide operating condition status on the CVXL-112, CVXL-115, or CVXL-215:
1) The POWER indicator (green) will illuminate when power is properly applied and the main power switch is
‘ON’.
2) The CLIP indicator (yellow) will illuminate when the sound output is near the maximum and automatically
reduced to prevent damage to the speaker. In such a condition, it is suggested to reduce the volume level so the CLIP indicator does not illuminate. Continued use, 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 a fault occurs and the speaker automatically places itself
into a condition where sound output is shut off. This condition may be the result of excessive clipping, excessive heat, or low voltage. These conditions all can cause significant damage to the product.
CUSTOM FEATURES
MODE
The MODE switch adjusts the contour of the overall frequency response optimizing the speaker for use as either a stage monitor (CVXL-112), for vocal reinforcement (CVXL-115, CVXL-215), or a main sound system (CVXL-112, CVXL-115, CVXL-215). When set to ‘MAIN’, the response is controlled by the MAIN EQ switch described below. When set to ‘MONITOR’ on a CVXL-112, the mid-range and sub-low frequencies are attenuated which helps increase focus on the low and high frequencies while potentially reducing feedback and muddiness. When set to 'VOICE' on a CVXL-115 or CVXL-215, the high and low frequencies are slightly attenuated allowing for better intelligibility when used as a PA (public address) system. It is recommended that users listen to their system with this switch in either setting to determine what is best for their needs.
MAIN EQ
The MAIN EQ switch adjusts the contour of the overall frequency response optimizing the speaker for use as either a main PA speaker or for playback of recorded music. When set to ‘LIVE’, the response is optimized for using the speaker as a PA (public address) or sound reinforcement system. When set to ‘PLAYBACK’, low frequencies are increased and mid frequencies are decreased to enhance pre-recorded music. These settings are ideal for situations where an external mixer or EQ device is not available or for playback only situations such as mobile DJ’s.
HIGH PASS 100 Hz
When engaged to ‘ON’, the HIGH PASS 100 Hz switch attenuates overall frequency output below 100 Hz. 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.

Rear Panel - Mixer - CVXL-118s, CVXL-218s
SIGNAL/CLIP INDICATOR
Each of the two 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. 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.
INPUT 1 & INPUT 2 INPUT JACKS
A combination input on each channel allows for either XLR or ¼” TRS cable types.
THRU 1 & THRU 2
The balanced XLR outputs THRU 1 & THRU 2 are high pass filtered from the respective INPUT 1 and INPUT 2 connectors. The crossover frequency of the high pass filtering is determined by the position of the CROSSOVER FREQUENCY switch.
LINK OUTPUT
This is a balanced XLR output that is the sum of the two input channels. This output is not affected by changes to the Main Level knob or the custom features. This connection is designed to provide an output which combines both input channels together for connecting to an additional powered speaker.
MAIN LEVEL 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.
INDICATORS
Three indicators provide operating condition status on the CVXL-118s and CVXL-218s:

2) The CLIP indicator (yellow) will illuminate when the sound output is near the maximum and automatically
reduced to prevent damage to the speaker. In such a condition, it is suggested to reduce the volume level so the CLIP indicator does not illuminate. Continued use, 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 a fault occurs and the speaker automatically places itself
into a condition where sound output is shut off. This condition may be the result of excessive clipping, excessive heat, or low voltage. These conditions can cause significant damage to the product.
