QUICK START UP

If you’re like most new owners, you’re probably in a hurry to plug your CX mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and the unit turned off, complete the following procedures:

1.CONNECTING AC POWER TO YOUR MIXER

•Check the rear panel to make sure the mixer received uses the proper AC Line Voltage. (USA 120VAC, Europe 240 VAC ...etc.)

•Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer.

2.CONNECTING SPEAKERS (Powered Models Only)

•Use the right and left 1/4” speaker jacks on the rear panel which are con- troled by the main level control on the front). The speaker cables should be non-shielded and at least 18 gauge(AWG) wire. For speaker cable runs of over 20 feet 16 gauge wire is recommended..

NOTE: Do not run your speakers through microphone wire, gui- tar cables, or multi-conductor microphone junction boxes or “snakes” as they are sometimes referred to. This wire is normal- ly shielded and of a very light gauge causing a substantial loss of power and oscillations at high frequencies in the amplifier. All speaker wires must be non-shielded.

3.SpeakerGuardtm and the “PROTECT” LED

•The protect LED comes on along with the output relays in three different pro- tection modes: Shorted speaker outputs, Speaker Impedance below minimum rating, and when the amplifier exceeds maximum operating temperature.

•In event the LED comes on turn off the amplifier and Identify and correct any speaker cable or speaker jack shorts and make sure the total speaker Impedance for each output is 4 ohms or greater. Also make sure the fan is not blocked and check that cool air can circulate around the rear of the mixer.

4.CONNECTING INPUTS TO YOUR MIXER

•For low level balanced devices such as microphones, plug into the balanced MIC inputs using a shielded microphone cable with XLR ends.

•For high level unbalanced devices such as Tape Recorders and Keyboards plug into the LINE input jacks using a shielded cable with 1/4” phone ends.

5.TURNING YOUR MIXER ON

•Adjust all channel and master level controls to their off positions (fully counter clockwise).

•Adjust all “EQ” tone controls— the channel’s Hi, Mid, and Bass and the two master 9 Band Graphic EQ’s to their center detent position.

•Adjust all the Channel “PAN” controls to their center detent position.

•Turn the mixer on by the rear panel power switch and watch for the power LED to come on. Your mixer is now ready to operate.

MAINTENANCE

To bring back the new look, your CX mixer can be washed with mild detergent and/ or a warm damp soft cloth. This will remove normal dust and oil from the front and back panels. Never spray cleaners or detergents directly at the unit. The mixer’s are virtually sealed from outside dust and dirt, but it is recommend- ed to keep the mixer free from dust, dirt, and moisture as much as possible.

CX1252 specifications

The Carvin CX1252 is a highly versatile and robust loudspeaker designed for both professional musicians and sound reinforcement applications. This two-way speaker has earned a solid reputation for delivering exceptional sound quality and performance, making it an essential component in various audio setups, including live performances, installations, and mobile sound systems.

One of the standout features of the CX1252 is its powerful dual 12-inch woofers. These woofers are engineered to produce deep, dynamic bass while maintaining clarity across the mid-range frequencies. The speaker utilizes a high-frequency compression driver that delivers crisp and articulate highs, ensuring a balanced audio experience across the frequency spectrum. Together, these components create a rich, full sound that is ideal for a wide range of musical genres and settings.

In terms of design, the CX1252 features a rugged, durable construction that can withstand the rigors of stage use and transportation. Its enclosed design minimizes distortion while maximizing efficiency, allowing for greater output without sacrificing sound clarity. The speaker is housed in a robust plywood cabinet, which is further reinforced to provide extra durability and reduce unwanted resonances.

The CX1252 also incorporates advanced technologies that enhance its performance. The built-in crossover network ensures seamless integration between the woofer and compression driver, resulting in smooth transitions and a cohesive sound profile. Additionally, the speaker’s wide dispersion pattern helps to cover larger areas, making it suitable for both small and large venues.

Another significant characteristic of the Carvin CX1252 is its versatility in powering options. It is compatible with a range of amplifiers and can be used in various configurations, including standalone setups and as part of larger sound systems. This flexibility makes it an ideal choice for different audio professionals, from DJs to acoustic musicians.

In summary, the Carvin CX1252 loudspeaker stands out for its powerful dual 12-inch woofers, high-frequency compression driver, and durable construction. Its advanced crossover network and wide dispersion pattern further enhance its appeal, making it a top choice for anyone seeking reliable and high-quality sound reinforcement. Whether for live events or installation purposes, the CX1252 is engineered to deliver outstanding audio performance and versatility.
