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 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.
CERWIN-VEGA PROFESSIONAL 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. STEP 1 Make sure the loudspeaker is unplugged. 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.
CERWIN-VEGA PROFESSIONAL Rear Panel - Mixer - CVX-10, CVX-15 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.
CERWIN-VEGA PROFESSIONAL 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 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).
CERWIN-VEGA PROFESSIONAL Rear Panel - Mixer - CVX-18s, CVX-21s 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.
CERWIN-VEGA PROFESSIONAL CUSTOM FEATURES POLARITY REVERSE In situations where the CVX-18s or CVX-21s is not optimally located, a polarity reverse switch is provided which inverts the audio signal by 180 degrees and can improve low frequency performance. In certain situations, the location of the subwoofer may be out of phase with the full-range speakers. By reversing the polarity of the subwoofer, the phase will match the full-range speakers with the benefit of not having to relocate the subwoofer.
CERWIN-VEGA PROFESSIONAL CVX Power Connections - Rear Panel The CVX power connections are located on the rear panel. It is suggested to understand the power connections and descriptions below to insure proper use. AC INPUT VOLTAGE SELECTOR The loudspeaker can be used with 100-120V AC or 220-240V AC power supply lines. Be sure the voltage selector switch is set to the proper voltage before connecting the power cord.
CERWIN-VEGA PROFESSIONAL Using the CVX-10 or CVX-15 as a floor/stage monitor The CVX-10 and CVX-15 can be used as floor monitors by orienting them as shown below. This places them at a fixed 45degree angle toward the performers. It is recommended to use MONITOR mode for this application, as it reduces the volume of frequencies that are prone to feedback. Be sure that the loudspeaker and cables are not located where they can become a tripping hazard.
CERWIN-VEGA PROFESSIONAL Using the pole mount - CVX-10 only The CVX-10 features a SHAFT GRABBER pole mount cup that reduces unnecessary wobble when the speaker is mounted on a pole. To use the SHAFT GRABBER, spin the disc counter-clockwise until the pole can fit into the pole mount cup. Next, spin the SHAFT GRABBER disc clockwise until the speaker has a tight fit with the speaker pole.
CERWIN-VEGA PROFESSIONAL Using the pole mount - CVX-15 only The CVX-15 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 to improve front audience coverage. Adjust the pole mount angle on the loudspeaker before it is placed onto a pole.
CERWIN-VEGA PROFESSIONAL Using suspension points - CVX-10, CVX-15 only The CVX-10 and CVX-15 suspension points are M10 threads with a depth of 25mm. On the CVX-10, two suspension points are located on the top handle with four pull-back points located on the rear of the unit. On the CVX-15, 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.
CERWIN-VEGA PROFESSIONAL Application #1 - Single CVX-10 or CVX-15 A single CVX-10 or CVX-15 powered speaker can be used to reinforce sound for a wide variety of performances. The diagram below shows an application where a vocal microphone, an acoustic-electric guitar and either a keyboard or media player are used together. Each individual channel volume can be adjusted to create the right balance while the main volume knob controls the overall audience volume.
CERWIN-VEGA PROFESSIONAL Application #2 - Adding a second CVX-10 or CVX-15 A second CVX-10 or CVX-15 loudspeaker can easily be added using a standard XLR/mic cable as in the example below. A two speaker system can cover a wider audience and situations where more volume is needed. To add a second CVX-10 or CVX-15 loudspeaker, connect the MIX OUTPUT of the first speaker to INPUT 1 or INPUT 2 on the second speaker then set the level and main volume to an appropriate setting on the first speaker.
CERWIN-VEGA PROFESSIONAL Application #3 - Adding a Subwoofer For public address (PA) or DJ applications where even greater bass response is ideal, adding a single subwoofer to a pair of CVX-10/CVX-15 speakers offers a high powered compact solution. In the diagram below, an audio source is connected to INPUT 1 and INPUT 2 on the CVX-18s/CVX-21s subwoofer and then the signal is linked to the CVX-10/CVX-15 speakers by using the CVX-18s/CVX-21s THRU 1 and THRU 2 outputs.
CERWIN-VEGA PROFESSIONAL Application #4 - Adding Two Subwoofers For demanding applications where even greater bass response is ideal, adding a pair of subwoofers to a pair of CVX10/CVX-15 speakers is a great idea. In the diagram below, an audio source is connected to INPUT 1 on each CVX-18s/CVX21s subwoofer and then the signal is linked to the CVX-10/CVX-15 speakers by using the CVX-18s/CVX-21s THRU 1 outputs.
CERWIN-VEGA PROFESSIONAL Application #5 - Subwoofer Cardioid Mode - Two Subwoofers For applications where multiple subwoofers are required but are located close to the performers, CVX subwoofers feature a cardioid mode setting which helps to reduce subwoofer levels behind the stage side while still achieving good audience coverage. The diagram and tables below show how to connect two CVX-18s/CVX-21s subwoofers using cardioid mode.
CERWIN-VEGA PROFESSIONAL Application #6 - Subwoofer Cardioid Mode - Three Subwoofers For applications where multiple subwoofers are required but are located close to the performers, CVX subwoofers feature a cardioid mode setting which helps to reduce subwoofer levels behind the stage side while still achieving good audience coverage. The diagram and tables below show how to connect three CVX-18s/CVX-21s subwoofers using cardioid mode.
CERWIN-VEGA PROFESSIONAL Application #7 – Daisy-Chain Some events may require several CVX-10/CVX-15 speakers spread across a long distance or a large stage front to provide adequate sound reinforcement for the entire audience. If there are multiple sources connected to the first speaker, the Mix Out from the first speaker should be used to daisy-chain to the next CVX-10/CVX-15. Any additional CVX-10/CVX-15 speakers should connect Input 1 to Mix Out of the previous speaker.
CERWIN-VEGA PROFESSIONAL Application #8 – Adding a CVX-10 or CVX-15 as a Stage Monitor In a live performance, a performer may wish to have a stage monitor to help hear the sound of the performance better. The diagram below shows a CVX-10/CVX-15 used as a stage monitor for the performer plus two CVX-10/CVX-15 speakers (daisy-chained) for the audience.
CERWIN-VEGA PROFESSIONAL Application #9 – Large Venue/Front of House In larger venues, the Front of House engineer has control of the entire sound reinforcement system using the console mixer. The diagram below shows how a console mixer interfaces with the performers’ on-stage audio equipment with several CVX-10/CVX-15 speakers directed towards the audience.
CERWIN-VEGA PROFESSIONAL Protective Grill All CVX model loudspeakers are shipped with the grill attached. It is recommended to leave the grill in place as it will prevent any accidental damage to the drivers that may result during transportation, setup, and general use. In the event that the grill needs to be removed, simply remove the hex-head screws around the edges of the grill. Remove the grill slowly to avoid damaging the gasket.
CERWIN-VEGA PROFESSIONAL Troubleshooting Problem No Sound No Power Shutdown Cause No connection to active AC power Solution Verify that the loudspeaker is connected to an active AC power source. Various outlets may need to be switched on. Use a lamp as another way to be sure the AC power source is active. Verify that the power switch on the back of the loudspeaker is set to the ON position. Adjust the LEVEL to a setting where sound can be heard. Incorrect power switch position Incorrect LEVEL setting.
CERWIN-VEGA PROFESSIONAL Troubleshooting (continued) Problem Bad Sound Cause Incorrect equipment settings, causing distortion Solution Check the meters on the external mixing console to ensure that the signal is not being clipped by the mixer. If the levels from the mixer are too high, correct the gain structure of the console, first by lowering the pre-amplifier trim (input sensitivity). If this does not lower the signal level sufficiently, then lower the channel faders.
CERWIN-VEGA PROFESSIONAL Care and Maintenance Before any cleaning or maintenance, be sure the loudspeaker is unplugged, turned off, and that all cables have been removed. Be sure to prevent any moisture coming into the openings of the speaker. The loudspeaker can be maintained cosmetically by using a dry cloth. Avoid using cleaning chemicals, as they may harm the finish of the loudspeaker. A direct burst of air should be avoided since it could harm the drivers or force debris into the enclosure.
