SETTING UP THE SOUND SYSTEM

This section is a brief overview of what it takes to hook up a sound system using a CX series mixer. The overview will include some of the different possible set- ups and some basics on how to mix live sound. If you are new to using mixers, you should find this section very informative in helping to operate your sound system properly. If you are experienced with mixers, then you may find some of the information new or presented with a new approach that can help you as well. As always, experimentation is the key to success, so don’t be afraid to use the controls to get a feel for what they do.

1. INPUT CONNECTIONS FROM THE STAGE

For live sound reinforcement or public address systems (P.A. Systems), the input signals to the mixer will come from the microphones and instruments on the stage. Each microphone or instrument to be amplified by the P.A. system must be connected to one of the mixer’s inputs. It is preferred to have as many of the stage instruments as possible plugged into the mixer. This allows the best over- all sound control of the instruments as they are mixed together and then ampli- fied by the P.A. system.

2. ON STAGE OPERATION

The CX Series mixers are small enough to have on stage. The advantages to this are: a band member can operate the mixer so no extra person is needed, and also the microphone, 1/4” phone inputs, and speaker cables are short and plug directly into the mixer, leaving no cables for the audience to trip over. The only disadvantages are the band member / mixer operator, on stage, doesn’t hear what the audience is hearing and because the mixer operator is a band member he can not react fast to problems with the “PA” system such as feed- back and sudden volume changes.

3. REMOTE TO STAGE OPERATION

Many times the mixer will be located a distance from the stage. This allows the performance to be monitored and mixed from the audience’s perspective. Monitoring at a distance from the stage usually means employing a multi-cable cable or more commonly referred to as a “Snake” (available from CARVIN). Each of the microphones and instruments are plugged into the snake box at the stage and the snake cable carries all these signals to the mixer. At the mixer, the snake cable, which fans out to plugs corresponding to the jacks on the snake box, is plugged into the appropriate inputs and line level (pre-amp) outputs of the mixer. All snake cables are numbered, both on the snake box and the cable, to help in keeping track of which microphones are being plugged into which chan-

nels. It is a good idea at this point to label each of the mixer channels according to what instrument each will be controlling. This can be done with masking tape (Scotch brand #230 drafting tape) or another suitable ‘light’ sticking tape. The tape will give you a surface to write on, to properly label the channels. The (XLR) balanced low impedance format will ensure the best possible performance and lowest possible noise when operating with long cable lengths, such as a snake.

CX420 specifications

The Carvin CX420 is a remarkable piece of audio technology tailored for both professional musicians and sound engineers who demand high-quality performance. Known for its versatility and exceptional sound clarity, the CX420 has garnered a reputation as a reliable tool in live performance and studio settings alike.

At the heart of the CX420 is its four-channel design, allowing for multiple inputs and the ability to mix different audio signals seamlessly. This feature is particularly beneficial for live band performances or recording sessions where various instruments and vocals need to be balanced correctly. Each channel is equipped with individual volume and EQ controls, giving users precise control over tone and timbre.

One of the standout technologies in the CX420 is its built-in effects processor. The unit comes with a range of high-quality effects, including reverb, delay, and chorus, allowing musicians to enhance their sound without the need for additional outboard gear. This not only simplifies the setup but also reduces the overall cost for performers looking to produce professional-quality sound.

Another notable characteristic of the CX420 is its sturdy construction. Designed with durability in mind, this audio mixer features a rugged chassis that can withstand the rigors of touring and frequent use. The user-friendly layout ensures that musicians and technicians can quickly adjust settings on the fly, with ergonomically designed knobs and faders.

In terms of connectivity, the CX420 excels with its array of input and output options. It supports both XLR and TRS connections, making it compatible with a wide variety of microphones and instruments. The mixer also features auxiliary sends for external effects and monitors, providing flexibility in routing audio signals.

The Carvin CX420 is not only a mixer but also a tool that enhances creativity. With its exceptional sound quality, user-friendly design, and robust features, it allows musicians to focus on making music rather than getting bogged down in technical details. Whether on stage or in the studio, the CX420 stands out as an essential asset for sound professionals seeking a reliable and high-performing audio solution.
