Congratulations on the purchase of your CX mixer. Your new CX series mixer demonstrates CARVIN’s commitment to producing the highest quality and most sophisticated engineering in the audio industry today. The CX series mixers were designed to be professional mixers in compact units. The CX includes a full function stereo mixer, with two nine band graphic equalizers, a digital signal effects processor and a powerful stereo amplifier. A rack mount version is also available without power amps. Each CX series mixer is surrounded by a strong, lightweight 3/4” poplar plywood cabinet covered with Duratuff II™ carpeting making the CX mixer road worthy.

CX OVERVIEW

The MIC/LINE input channels feature XLR and 1/4” LINE inputs with phantom power for condenser mics. There are 3 bands of EQ, a post fader effect send, and a monitor prefader send on each channel. The master section features two 9 band graphic EQs, master stereo main and monitor mix controls, a complete 16 program effects processor with send and return controls, and a stereo external effects return.

“SHELVING” EQ WITH ACTIVE TONE CIRCUITS

The CX series incorporates 3 bands of EQ per channel. They offer smooth tone curves so your adjustments will sound natural and yet be effective. The high (treble) and low (bass) “shelving” type controls cover the complete upper and bottom portions of the audio range. The MID EQ controls are a “band pass” type which peak at 2.2k Hz for added presence to your mid range tones. Because CARVIN uses “active” tone circuits, you are able to boost or cut your tones without any signal loss to your sound.

RECEIVING INSPECTION—read before getting started

INSPECT YOUR MIXER FOR ANY DAMAGE which may have occurred during shipping.

If any damage is found, please notify the shipping company and CARVIN immediately.

SAVE THE CARTON & ALL P ACKING MA TERIALS. In the event you have to re-ship your unit, always use the original carton and packing material. This will provide the best possible protection during shipment. CARVIN and the shipping company are not liable for any damage caused by improper packing.

SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.

SHIPMENT SHORTAGE. If you find items missing, they may have been shipped separately. Please allow several days for the rest of your order to arrive before inquiring.

RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for your records. Keep your portion of the card and return the portion with your name and comments to us.

INTERNAL SIGNAL ROUTING

Your balanced mic or instrument plugs directly into the high quality XLR Neurtric™ connectors and is then routed into the differential circuits for excellent hum and noise cancellation. As your signal continues within the console, a double-sided printed circuit board (FR-4 fire rated) carefully guards the circuit traces with a copper shield running over the traces. This eliminates RF interference and reduces crosstalk substantially. The printed circuit board has plated-through holes which means that every component is soldered securely in three places (bottom, in the hole and on top). This offers unsurpassed component security while reducing circuit resistance for pure dynamic sound.

HEADROOM

Headroom is very important when designing a mixer—especially for recording. Lack of headroom will cause your sound to become distorted and muddy. This can happen when you turn the volume too high, if the input signal is too hot or if excess bass or treble is added. With most mixers, you have to reduce the input gain to fight headroom problems, but this just increases noise. That’s why we have taken great care in the CX series to make sure that each gain stage is properly designed and balanced for more headroom along the entire audio path.

TOROID SUPPLY

A big feature in the CX power supply is the precision wound Toroid transformer (not available from our competitors) that offers lighter weight with massive current capability for the power amp. The toroid based power supply also offers unsurpassed rejection of noise and hum while providing precision voltage for all preamp stages. Now you can go anywhere and never worry about inconsistent sound due to fluctuating voltages. CARVIN has spared no expense to achieve the best possible quality & performance.
